What to look for when choosing the best solar installer for your projects

When doing a solar review to select the right company for your project, you need to ask the right questions.

Asking the right questions will make it easy and faster for you to identify the perfect solar installer.

Here are some of the questions to ask when selecting a solar installer for your solar installation projects.

1. What’s the capacity of the solar company?

This answer to this question depends on the scale of the project and the capacity of the solar company.

Most small scale solar installers have expertise in setting up solar power systems for small scale purposes.

Their capacity will be able to build solar energy systems for homes, small shops and SMEs.

However, they may not be fit to carry out larger projects like building a solar mini-grid system. 

On the other hand, a full-stack solar installation company will be able to handle both small and large scale projects.

This makes it easy for you to use them for all of your projects and maintain consistency products and service delivery.

2. Does the solar installer have the necessary licenses and insurance?

Solar installation projects are very risky because it involves the use of very fragile solar panels.

Also, home solar installers most times install solar panels on rooftops and are susceptible to accidents. 

To be sure that you do not bear an unnecessary cost of damages, you need to make sure that the solar company has insurance cover for all products.

The insurance cover should be valid during shipment as well as during installation.

Ensure that the solar installer has government-approved licenses or face the consequences of leaving your project to amateurs.

3. Does the installer provide warranties and after-sale services?

Warranties are really important for solar projects to ensure that the system does not breakdown within a short period of time.

Warranties generally range from 1 to 10 years.

You need to be sure that your installer is available to provide you with all the help you need after the project is completed.

That way, you can confirm that the system is in perfect working order before you finally take full responsibility and liability.

4. Has the solar company worked on other solar projects?

When conducting solar reviews, you may want to ask this question to know whether they plan to learn on with your project.

Make sure your installer has a good track record and experience in setting up solar panels.

To make it easy for you, you can request for the solar provider to show you solar power systems done for previous clients.

With pictures and other proof of project existence, you can conclude whether the installer is the right pick for the job or not.

5. What are people saying about the solar installation company?

A company becomes popular when a lot of people keep using their products or services.

Although, some good solar companies may not be so popular, yet they are good.

For those ones that are really popular, you need to read online reviews about them.

Carefully observe the negative reviews from customers. 

If you notice any pattern or similar complaints, it is most likely that you will suffer the same problem.

While some clients may overexaggerate their experience with the solar installer, you should be thorough with your conclusions.

The economic development of communities is heavily dependent on energy access; however, many rural settlements remain unconnected to the national electric grid.

Onono-Anam in Anambra State, Nigeria is one such community, where the lack of electricity has adversely affected the social, health and economic life of the inhabitants of this community who are largely smallholder farmers and petty traders.

Only a handful of the 500 homes in this rural community can afford small generators to meet some of their energy needs, whilst the other inhabitants mainly rely on smoky kerosene lamps and fuel wood.

However, the launch of a 24kW solar mini-grid in 2016 ushered a new era of unlimited power supply which culminated in improved socio-economic well being for Onono-Anam. Several homes are now powered by solar energy; agro-processing now thrives in the community, and night time security has been enhanced.

Over 50 direct and indirect jobs have been created during the project implementation, alongside knowledge transfer, as some of the inhabitants are still involved in post-installation operations. The positive impact of this project has resulted in the installation of an additional mini-grid to serve an additional 300 households in Onono and surrounding communities of Okpechalla, Atachile and Okilo.

Energy access for improved health

Up North in Bisanti, Niger state, the installation of a 40kW solar mini-grid was made possible through a partnership with the Bank of Industry, the United Nations Development Program, and the Institute of Electrical Electronics Engineers (IEEE).

This mini-grid installation has been of immense benefit to the community. Over 300 households and approximately 1,600 people are now connected to the grid. Residents who ran petrol-powered generators for as much as N600 naira for 3 litres could now access 24-hour power supply for 44.5% for that same amount.

Security and social interactions also have greatly improved, and the Primary Healthcare Centre in the community has recorded a 60% reduction in malaria cases in the community.

Many of the residents in this community attest to improvements in their health and well-being as they can use electric fans to sleep comfortably at night despite the heat and humidity synonymous to the region. The local economy has further blossomed as 35 micro, small and medium enterprises have been connected to the mini-grid, and farmers can now irrigate rice farms and earn more money.

The overarching desire of Green Village Electric Projects Limited is to see economic growth and improved social well-being in communities, without compromising environmental sustainability.

In Akpabom, Akwa Ibom State where a 100kW mini-grid was installed, sponsored by the Rural Electrification Fund and All On, businesses and can now run for longer with reduced cost often spent in the past on diesel or petrol for generators. Energy-related spend is now down by 40%.

As a coastal settlement, Akpabom’s fishermen have reduced post-harvest loss as the uninterrupted power supply avails them the opportunity to preserve fishes thereby yielding more income.

The social impact of the projects has resulted in improved quality of life. In Akpabom, there is a 68% downfall in malaria cases experienced in the community, and children could study and play more with the help of street lighting.

Goal: clean and affordable energy for all

As an industry leader, Green Village Electric (GVE) Projects Limited is at the forefront of providing clean and sustainable energy solutions to unserved and underserved rural communities. They also offer off-grid renewable energy solutions to commercial users – such as healthcare, agro-businesses – and residential users. GVE Projects has grown from a student-led idea in 2009 to a company with a staff strength of over 40 employees, serving over 8,984 households across the nation.

The company recently signed the first interconnected mini-grid tripartite agreement in Africa with the Abuja Electricity Distribution Company Plc and Wuse Market Association to Develop a 1MW PV Solar Hybrid system for Wuse Market, Abuja – Nigeria.

Through seed funding, grants, equity/debt financing by organisations such as the IEEE, USADF, USAID, GE Africa, European Union, All On, Rural Electrification Agency/Rural Electrification Fund, UNDP, and the Bank of Industry, GVE has successfully implemented 13 mini-grid projects across the country with new projects in the pipeline Plateau, Rivers, Kogi, Anambra and the FCT.

GVE hopes towards achieving SDG7 – affordable and clean energy for all – while putting smiles on people’s faces, this they have been doing across various communities like Bisanti, Kolwa, Onono, Kolaku, and Egbeke. The company’s target is to serve 3.6 million people in Nigeria and expand into the West African market over the next few years.

What is Renewable Energy?

Renewable energy in Nigeria refers to the energy that comes from renewable resources.

It is also referred to as clean energy and it comes from natural sources or processes that are constantly replenished. 

For example, sunlight or wind keep shining and blowing, even if their availability depends on time and weather.

Types of Renewable energy includes solar, wind, hydro, oceanic, geothermal, biomass, and other sources of energy that indefinitely renew itself in nature.

Forms of useable energy include electricity, hydrogen, fuels, thermal energy and mechanical force.

Beginning of Renewable Energy

While renewable energy is often thought of as a new technology, man has been harnessing nature’s power for a very long time.

We have been using renewable energy for heating, transportation, lighting, and more. 

For instance, man has been using wind to propel boats to sail the seas and windmills to grind grain. 

Also, man harness the sun to provide warmth during the day and help kindle fires to last into the evening. 

But over the past 500 years or so, humans have been increasingly turning away to cheaper, dirtier energy.

Such energy sources like coal and fracked gas have greatly affected our climate and weather conditions.

Now that technology is helping the world to increasingly innovative and uses less-expensive ways to capture and retain wind and solar energy, renewables are becoming a more important power source.

In the U.S.A, for instance, renewable energy sources account for more than one-eighth of US total energy generation. 

The expansion in renewables is also happening at scales large and small, from rooftop solar panels on homes that can sell power back to the grid to giant offshore wind farms. 

Even some entire rural communities rely on renewable energy for heating and lighting.

What are the Sources of Renewable Energy in Nigeria?

Nigeria has an abundance of various renewable energy resources.

However, Nigeria generates a small amount of energy from only four main renewable energy sources. They are 

  • Hydropower
  • Solar
  • Wind
  • Biomass

Status of Renewable energy in Nigeria

Electricity distribution is holding Nigeria back. 

Electricity shortages significantly impede Nigeria’s economic growth. 

Some parts of the country have little or no access to the national grid.

Meanwhile, in other areas electricity is only available for short and varying periods of the day.

Renewable energy penetration in Nigeria is still in its beginning stage.

The only source of renewable energy in the country is hydro-power and biomass.

Even though there is the presence of wind and solar energy, they have only been deployed in a minimal amount.

To date, fossil fuels entirely dominate the national energy supply in Nigeria. 

Renewable energy resources are grossly underutilised in the country despite their availability in reasonable quantities.

Government Contribution to the Development of Renewable Energy

Even though many homes have been using renewable energy sources prior to this time, the Nigerian government, in 2003, introduced renewable energy as part of its national energy policy.

Successful implementation should result in the installation of enough wind, solar PV, solar thermal, and hydroelectricity sources by 2025 to provide the equivalent of the entire grid capacity in use in Nigeria today.

The Nigerian Electricity Regulatory Commission (NERC) is already committing to stimulate investment in renewable energy generation in Nigeria. 

With a vast and mostly untapped potential in renewable energy resources, the Commission has set a target of generating a minimum of 2,000MW of electricity from renewables by the year 2020.

The main feature of this project include;

  • Guaranteed price & access to the grid
  • Feed-In – Tariff for Solar, Wind, Biomass & Small Hydro
  • Power Purchase Agreement (PPA) based on the plant life cycle of 20 years
  • Electricity distribution companies (DisCos) to procure a minimum of 1000MW (50 per cent of the total projected renewable sourced electricity)
  • Nigerian Bulk Electricity Trading Company (NBET) to procure a minimum of 1000MW (50 per cent of the total projected renewable sourced electricity)

If this project becomes real, we can be very sure of it having a positive impact on the state of electricity generation and distribution in Nigeria.

The use of renewable natural resources, in combination with efficient supply and use of fossil fuels with cleaner technologies, can help reduce the environmental effects of energy use.

It will also help Nigeria in replacing the existing, inefficient fossil fuel technologies that pollute the environment.

Private Sector Participation in Renewable Energy Development

When it comes to private sector participation in the development of renewable energy in Nigeria, GVE Projects Limited is at the forefront of this.

Green Village Electricity (GVE) Projects Limited is the foremost and most innovative renewable energy solutions provider in West Africa.

The company is registered with the Corporate Affairs Commission of Nigeria (RC1071222).

GVE Projects Limited has a lot of achievements in its coffers.

This is because of incredible clients and sponsors like you, private and public partners.

Also, we have been able to position the company as the leader in Nigeria’s renewable energy industry.

We create value for our numerous clients through world-class service delivery with a touch of unique local contexts.

Thanks to the expertise and dedication of our board of directors, management, employees and our various business associates.

We also have a long history perfectly completing renewable energy projects especially solar mini-grid installations around Nigeria.

Most recently, we completed a 1MW interconnected solar mini-grid in partnership with the AEDC to provide constant electricity to the modern Wuse Market in Abuja.

Obviously, this interconnected electricity distribution agreement is the first of its kind in Nigeria.

Moving Foward

As pioneers launching new frontiers in the renewable energy industry in Nigeria, we hope to reach that point where Nigeria has most of its energy coming from renewable energy sources.

In addition, we are working really hard to see that Nigeria continues to get a 24/7 supply of electricity for daily economic activities.

It’s our vision to be the first-choice global renewable energy solutions provider while also providing reliable and sustainable energy solutions to our clients.

With our eyes set on this mission alongside a strategic collaboration with companies and sponsors, we hope to transform the energy and electricity situation in Nigeria.

Off-grid solar systems are completely independent of the power grid. You can also refer to them as independent solar power or stand-alone solar power.

What this means is that with off-grid solar systems you will not need backup power from power companies.

You can only use what your solar energy system produces and what you have stored in your battery bank.

Because off-grid solar energy systems must do not have backup power, they typically have much bigger battery banks than grid-tied solar systems with a battery backup.

Benefits of the off-grid solar system

The use of this type of solar energy system comes with its own advantages too.

  1. Avoid Power Outages: No more fears of power outages. Off-grid solar energy systems are reliable for outage situations. These systems store energy even when for some reason the power company is unable to supply electricity.
  2. Reduced electricity costs: Off-grid solar systems rely on sunlight to provide the power you need. As a result, this adds nothing in your monthly electric bills.
  3. Easier Installation: By using simple tools, a homeowner can install a solar off-grid system on their own. This can help reduce the overall system cost substantially.
  4. Easy Alternative for Rural Areas: Rural and remote areas usually have fewer infrastructures. Therefore, connecting them to the main electrical grid can be a challenge and incredibly costly. But by using off-grid solar energy systems, one can offset this significant role. With sponsorship, one can build a solar mini-grid system in a rural area.
  5. Keeping the Environment Clean and Green: Renewable energy sources such as off-grid solar powered systems minimizes carbon footprint that keeps the air and environment clean. Using off-grid technology helps to provide electricity and also reduce your consumption of fossil fuel. Also, this will help minimize the negative impact on the environment

How to set up an off-grid solar system

Now that you know some benefits of the off-grid solar system, you are welcome to think about building one immediately.

However, there is an issue.

No one wakes up one morning to start installing an off-grid solar system without having prior knowledge of what to do.

That is, in fact, the exact reason for this article.

If you want to design a system like this one, you are welcome to use these steps in this article.

Here are the 6 steps to get you started.

1. Figure out how much power you need

This is the most important step in this process, and many people try to skip over it. Don’t be like many people who go by assumptions.

You must sit down and calculate your power load before choosing the components you need for installation.

This calculation will help you determine how much time your solar off-grid system will run.

You’ve got to remember absolutely everything that will be powered by your system.

Any little change in your calculation can make a big difference.

With a basic knowledge of mathematics, you can do the calculation very easily.

  1. Decide what appliances (bulbs, AC, fan, TV etc ) you want to run and how much time (hours).
  2. See the specification chart in your appliances for power rating.
  3. Calculate the Watt Hour which is equal to the product of the power rating of your appliances and run time (hours). Load Calculation Example: Let’s say you want to run a 50W Fan for 4 hours from a solar panel, then the watt-hour is equal to  (CFL) for 5 hours from a solar panel, then the watt-hour is equal to; Watt Hour = 50W x 6 hr = 200
  4. Calculate the total Watt Hour: Just as with the fan you’ll now calculate the watt-hour for other appliances in your home and add them together. Example: compact fluorescent lamp (CFL) = 11W x 7 hr = 77; Fan = 50 W x 4hr = 200; TV = 80W x 3hr = 240
    Total Watt Hours = 77+200+240 = 517

If you have more than one appliance of the same kind, you can multiply the watt-hour for that appliance by the number available.

Now that the load calculation is over, the next thing is to choose the right components to match your load requirement.

Note: If this process is too much maths for you to do, you can just key in the appropriate numbers in this load calculator. There are many other load calculators available on the internet that will serve the same purpose.

2. Calculate the number of batteries you need

Now that you know how much power you need, you need to figure out how many batteries you need to store it.

  • Do you need only enough storage for a day or two?
  • Is there a need to have enough batteries to store 3 or 4 days, or more, worth of power?
  • Do you have another power source, like a generator, that will kick in if the sun doesn’t shine?
  • Will you be storing the batteries in a warm room or will they be in a cold location?

Batteries are rated for storage at around 80 degrees Fahrenheit. The colder the room, the bigger the battery bank you need – by over 50% more for below freezing. Each of these answers affects the size, and cost, of your battery bank.

What voltage battery bank do you need for the off-grid solar system – 12V, 24V, or 48V?

Before going to choose the components for installation, you must decide your system voltage, 12V, 24V or 48V.

The higher the voltage, the lesser the current and the lesser the copper loss will be in the conductor.

This will also reduce your conductor size. Most of the small home solar systems will have 12 V or 24 V.

On the other hand, the larger the system, the higher voltage battery banks are used to keep the number of parallel strings to a minimum and reduce the amount of current between the battery bank and the inverter.

If you are just owning a small system, and want to be able to charge your cell phone and power 12V DC appliances in your RV, then a basic 12V battery bank makes sense.

But if you need to power much over 2000 watts at a time, you’ll want to consider 24 volt and 48 volt systems.

Besides reducing how many parallel strings of batteries you’ll have, it’ll allow you to use thinner and less expensive copper cabling between the batteries and the inverter.

3. Calculate the number of solar panels needed for your location and time of year

Using the off-grid calculator from the previous step, you can also figure out how many solar panels you’ll need for your solar system.

After knowing how much energy you need to make per day from the load calculator, you’ll need to tell it how much sunshine you’ll have to harvest from.

This available energy from the sun for a location is referred to as “sun hours.”

The number of “sun hours” is how many hours the available sun shining on your panels at an angle throughout the day equals sunlight, as if it were shining directly on your solar panels when they get the most power.

As you know, the sun isn’t as bright at 8 AM as it is at noon.

So, an hour of morning sun may be counted as half an hour, whereas the hour from noon to 1 PM would be a full hour.

Unless you live near the equator, you do not have the same number of hours of sunlight in the winter as you do in the summer.

You want to take the worst-case scenario when determining the available energy from the sun for your area.

The best option is to choose the season with the least amount of sunshine or sun hours.

That way, you do not end up short on solar energy for part of the year.

4. Select a solar charge controller

Now that we have the batteries and the solar panels we need, the next requirement is a way to manage the transmission of power from the solar panels into the batteries.

A solar charge controller is a device which is placed between a solar panel and a battery.

It regulates the voltage and current coming from your solar panels.

It is used to maintain the proper charging voltage on the batteries.

As the input voltage from the solar panel rises, the charge controller regulates the charge to the batteries preventing any overcharging.

An extremely rough calculation to figure out what size solar charge controller you need is to take the watts from the solar, and divide it by the battery bank voltage.

Then you add another 25% for a safety factor.

Types of Charge Controllers:

Now there’s a bit more to consider with selecting the charge controller. These are the 3 main types of charge controllers;

  1. ON OFF Charge Controller
  2. PWM Charge Controller
  3. MPPT Charge Controller

As much as you can, try to avoid the ON/OFF charge controller as it is the least efficient type.

Among the 3 charge controllers, MPPT has the highest efficiency but it is also relatively expensive than the others.

So, if you are to select a charge controller, you can use either pick the PWM or MPPT.

Here are some tips to help you determine the exact charge controller to use.

  1. If the voltage of the solar panel array matches the voltage of the battery bank, you can use a PWM charge controller. For instance, if you have a 12V panel and a 12V battery bank, then use PWM.
  2. If your solar panel voltage is different from the battery bank voltage, and can’t be wired in series to make it match, you need to use an MPPT charge controller. In essence, if you have a 20V solar panel and you have a 12V battery bank, you need to use an MPPT charge controller.

solar off-grid system charge controller

5. Select an inverter

Now that we have efficiently charged batteries, we need to make the power usable. If you are only running DC loads straight off your battery bank, you can skip this step.

But, if you are powering any AC loads, you need to convert the direct current from the batteries into alternating current for your appliances.

Solar power systems work by first receiving sun rays on the solar panels (PV) which converts the rays into direct current (DC) electricity.

Then, you use a device known as an inverter to convert the DC into alternating current (AC).

AC electricity circulates through every outlet of your home, powering all the appliances.

Inverter Types

There are three main types of inverters for solar installations.

  1. Square Wave
  2. Modified Sine Wave
  3. Pure Sine Wave

Square wave inverters are the cheapest but they are not suitable for all appliances.

The Modified Sine Wave inverter output is also not suitable for certain appliances, especially those with capacitive and electromagnetic devices such as a fridge, microwave oven and most kinds of motors.

Typically modified sine wave inverters work at lower efficiency than pure sine wave inverters.

So, if you are to chose an inverter for your off-grid solar system, I will urge you to choose a pure sine wave inverter.

The inverter may be grid-tied or stand-alone. In our case, it is obviously stand-alone and completely off-the-grid since we are working on an off-grid solar system.

It is also very important to know what type of AC power you need. In North America, the standard is a 120/240V split-phase, 60Hz.

In Europe and much of Africa and some countries in South America, the AC power requirement is 230V single 50Hz.

Some inverters are configurable between voltages and/or frequencies, while many have fixed values.

So, you need to carefully check the specs of the inverter you are purchasing to make sure it matches your needs.

Rating of Inverter:

The rating of the inverter you are going for is also an important metric to consider.

The power rating should be equal or more than the total load in watt at any instant.

Luckily, way back in step one, you created a loads list that figured out both the constant watts and surge requirements of your loads.

From our example, the maximum load at any instant = CFL (11W) + Fan (80W) + Tv (50W) = 141W

By taking some margin we can choose a 200W inverter.

As our system is 12V we have to select a 12V DC to 230V/50Hz or 110V/60Hz AC pure sine wave inverter.

Please note that an inverter is designed for a specific voltage battery bank, like 12, 24 or 48 volts.

So, you need to know what voltage battery bank you are going to have before you settle on the inverter.

Keep this in mind if you have plans of expanding your solar power system in the future.

If you plan on having a higher voltage battery bank later, be aware that the lower voltage inverter won’t work in the new bigger system.

Therefore, you can either plan ahead and go with a much higher voltage from the start or plan on changing out your inverter in the future.

#6 Balance of system

Much of the work you require to build an efficient off-grid solar power system has been explained from step 1 – 5.

In this final stage, all that is left for you to do is to mount the solar panels in such a way that it will always receive sunlight.

To achieve this, you need to slant the solar panels at an angle and fasten them to your rooftop or in your backyard.

The next is to run a series and parallel connection of the batteries, build the inverter and battery stand and then complete the wiring.

To balance the system, you should look into these little components including:

  • the fuses and breakers for overcurrent protection
  • what breaker boxes will be used
  • what size wire you will need

Once you’ve gone through these 6 steps, you’ll be off and running to designing your own DIY off-grid solar system.

What’s a solar mini-grid?

Providing electricity to rural populations can take any one of three forms: grid extension; standalone solar systems; and solar mini-grid system.

A mini-grid is a small scale electricity network fed by solar energy. Mini-grids represent an interesting and important midway point between stand-alone and major grid electricity systems.

They typically serve remote communities that are not economical to connect to large grids due to their isolation.

For a community that has sufficient population density and diversity of end-users, it makes sense to connect them together.

Using mini-grid systems will save the government a lot of cost in providing stand-alone systems to supply electricity.

The use of a mini-grid also permits the use of generation technologies that might not be feasible or economical at a smaller scale.

Some examples include multiple diesel gen-sets, biomass, as well as small hydro facilities.

However, at GVE-Projects Ltd, we provide electricity solutions for rural, residential and commercial needs using solar mini-grid systems.

We generate and supply electricity– directly or indirectly via batteries – to clients who are connected to this mini-grid electricity network.

A group of people living close to each other, for instance, a village, can easily connect to this mini-grid.

We use the mini-grid technology when our customers have higher energy requirements.

The advantage of a solar mini-grid is that it can meet higher energy demands by for instance local businesses.

A solar mini-grid boosts business activities in rural areas, but can only be realised economically if the distance between clients is relatively small and there is sufficient electrical demand.

How does a mini-grid work?

The way the mini-grid works is very simple. We use solar panels to capture sunlight, which we convert into electricity.

Electricity then goes to an inverter that converts direct current into alternating current.

The alternating current is then fed directly or indirectly (via the batteries) into the electricity network.

Using pole lines to distribute the electricity around the community, it reaches all customers who connect to the network.

In some cases, a diesel generator is used as a back up for the solar power plant.

The generator will feed the network or batteries at times when solar energy production is insufficient.

While the batteries of the electricity network are recharging via a diesel generator, customers will not have access to the network for a period of time.

Advantages of a mini-grid:

There are numerous advantages to the use of solar mini-grids for rural electrification in Africa.

  1. As they’re not connected to the main grid, mini-grids only generate enough electricity for local consumption.
  2. This local nature of mini-grids allows developers to better track and understand a community’s energy needs so electricity supply can match demand.
  3. Mini-grids also avoid the problem of power cuts from the main grid, ensuring a less intermittent supply of electricity.
  4. A more dependable electricity supply allows businesses to stay open later and develop faster.
  5. Clinics also benefit from having constant power supply as well as small provision stores selling cold drinks.
  6. Households can now power fridges, fans and also charge their phones easily.
  7. Solar mini-grid system design requires little maintenance
  8. What’s more satisfying about the solar mini-grid system is that there is no dependence on the import of diesel and fluctuating energy prices
  9. Being environmentally friendly, the solar mini-grid system does not emit pollutants into the surrounding.

You see that the advantages of installing a solar mini-grid system are numerous.

GVE-Projects Ltd has installed a lot of solar mini-grid systems in various communities and business centres in Nigeria.

We are always available to provide energy solutions for your everyday use.
