FAQs on Solar Renewable Energy System
What are the financial benefits of Solar Renewable Energy?

When you install a Solar Renewable Energy system on your property, you save money on your electricity bills and protect yourself against rising electricity rates in the future. You also protect yourself against rising recurrent expenditure on servicing, fuelling & maintaining power generators. In Nigeria, the financial benefits of a Solar Renewable Energy System cannot be over-emphasized in such days of fuel scarcity and low power supply on the Utility grid. Generally, how much you can save depends on the utility rates in your area, but going solar is a smart investment regardless of where you live.

What are the environmental benefits of Solar Renewable Energy?

Solar power, like other renewable energy resources, has many environmental and health benefits. Going solar reduces greenhouse gas emissions, which contribute to climate change, and also results in fewer air pollutants like sulfur dioxide and particulate matter, which can cause health problems.

How do I find out how much I pay for electricity?

The easiest way to find out how much you pay for electricity (and how much electricity you use per month) is to take a look at your utility electricity bill. Don’t also forget to factor the amount you spend in servicing, maintaining and fuelling your power generator.

Do my Solar Renewable Energy system produce power when the sun isn’t shining?

The amount of power your Solar Renewable Energy system can generate is largely dependent on two major factors:
The first factor is the amount of sunlight. In cloudy or rainy days, or at night, your solar panels will produce slightly less energy or no energy.
The second factor is the size of your battery bank. You can decide to have a battery bank large enough to get you covered for days or weeks which depends on your situation and your budget.

Can I go off grid with solar panels?

When you install solar panels on your property, you will still be connected to the Power Utility grid (NEPA) – This is referred to as On-grid. This allows you to charge your battery bank and draw from the grid when your system is not producing all of the power that you need, It is possible to go off the grid with a solar Renewable Energy System; it will cost significantly more.

Will I still receive an electric bill if I have solar panels?

Unless your Solar Renewable Energy system is an off-grid system, you will still receive a bill from your utility (NEPA). However, you can dramatically reduce your bill, or even cut your electricity expenses to ₦0, with a solar Renewable Energy system that matches your energy use.

How much will solar panel maintenance cost?

Solar panel systems are made of durable tempered glass and require little to no maintenance for the 25 to 35 years that they will generate power. In most cases, you don’t even need to clean your solar panels regularly.

Can I afford to go solar?

If you can afford to pay your electricity bill you can afford to go solar.

Is my roof suitable for solar panels?

Roofs with little to no shade and enough space to fit a solar panel system are ideal for installing solar. However, in many cases there are workarounds if your home doesn’t have the ideal solar roof. Our valued technical team shall proffer various options during the course of their site inspection and Energy Audit.

How do Solar Renewable Energy System work?

Solar panels absorb the sun's energy throughout the day. Sunlight on Solar Panels produces direct current (DC) electricity which is stored in your Battery Bank and then converted to alternating current (AC) by a device called an inverter. The output of the Inverter is then wired into your main service panel where it feeds your internal power grid(Load). For more details, click here

How do I determine how large a Solar Renewable Energy system I'll need?

The size of the system is usually directly proportional to the amount of power you use. As part of the proposal process, 3Smart Technologies will perform a site assessment and analyze at least twelve months' worth of utility statements or perform a Load Audit as the case may be. With that information, 3Smart Technologies will present recommendations for your input and feedback with the goal of making sure you feel the ultimate path chosen is ideal.

How much do these systems cost and how much money will I save each year? How long will it take to pay back my investment?

The size of the system is the largest determinant of the price, and the savings rise accordingly. In most cases, the payback period for the investment in a photovoltaic system is roughly 5 years with internal rates of return ranging from 15% to 25%, depending on the avoided cost of energy and the site-specific design and resulting costs.

Is financing available?

The best source of financing is usually the bank, finance company, or mortgage company with whom you currently work.

We don't own the property on/in which we operate. Can we still go solar?

Yes, it's relatively commonplace for property owners to allow their tenants to make improvements in their facilities and we have many customers who are tenants with long-term leases.

Will a roof-mounted system void my roofer's warranty?

We frequently coordinate our work with roofers to ensure warranties remain in force.

My building's roof needs replacing soon. Does it make sense to integrate the installations?

Yes. If you're planning to replace your roof in the next few years, it may make sense to move that up and install the PV system at the same time as the new roof is going on.

How long will my installation take?

This depends mostly on the size of the system, site location, and whether there is an existing electrical /inverter-battery system or not. In general, an Off-Grid 10Kva Renewable Energy System shouldn’t take more than 24 business hours to be installed.

Will installation interfere with my normal business operations?

Most work is conducted on the site of the array installation (roof or ground) and on the electrical board. So, your operations will likely be impacted by the electrical work. We coordinate our efforts with your team, from deliveries, securing equipment and we always schedule site material deliveries and other electrical

What are the maintenance procedures and costs?

Solar PV systems are solid-state technology, have no moving parts and require no maintenance beyond cleaning, which can typically be done with a garden hose. Most systems should be cleaned once or twice a year, concentrated in the dry season. Systems in agricultural areas will likely require 2-3 cleaning per year. Inverters are also solid-state and require little to no maintenance beyond regularly checking the cooling fan outlets and cleaning when necessary.

Does cleaning the modules require any special expertise or equipment?

No special skills or equipment needed. At the completion of each installation, we’ll train your team on how to clean your solar panels. We can also offer scheduled cleaning programs.

What parts will break first?

The inverter(s), which typically have a useful life of 15-20 years, will be the first thing to fail.

How long will Solar Panels last?

Based on manufacturers' in-field experience and reliability testing, Solar Panels will probably last longer, and are more reliable than just about any other capital investment for your business. In 2003, BP Solar published the results of their analysis of warranty claims and reported that of more than two million modules in service over nearly ten years, approximately one-tenth of one percent were reported faulty, noting "this represents one module failure for every 4,200 module-years of operation." Put another way, if your system has one thousand modules, you may experience the failure of ten modules in 40 years.
