“How Can I Maintain My Solar Panels and System to Get 24/7 Electricity in Nigeria?” Expert Advises


A young man who spent millions of naira installing a solar system in his became frustratedDespite how much he had spent on solar panels and batteries, he still could not get longer energy backup hoursA solar expert, Osadebe, explained why power management is important when running solar and how to maximise energy

An anonymous asked:

“How do I maintain my solar panels and system to get 24/7 electricity in Nigeria?

Stable electricity has been one of the core challenges in Nigeria for decades. In recent times, the national grid collapsed many times.

With the high cost of fuel, running a is no longer a cheap alternative, as many are looking towards solar energy.

While setting up a solar system may be a good alternative, power management, and load sizing are things many still do not know. If generating electricity from the sun is the solution, how then does one achieve longer hours with a solar setup?

David Osadebe is an expert in solar systems and mobile inverters. He specialises in the design/build, installation, and optimization of power conversion technologies. David's expertise encompasses various types of inverters, ranging from mobile inverters to DIY setups and full home installations, including grid-tied, off-grid, and hybrid systems.

Using solar for the first time: what you should know

A person wanting to use solar energy for the first time must determine how much power he or she will need. If they have no basic knowledge about it, they'll have to call a professional installer and explain what home appliances he or she wants to run on the inverter and how many hours they want the system to run those loads during sundown. That will enable the installer to give them the right inverter KVA and the right battery KW to run the loads efficiently.

Power management and load sizing for solar

Sizing your solar system is very important if a user wants to maximize usage. It's important to stay on the watts consumption you paid for. The mistake some users make when setting up a solar system at home or office is telling the installer what they want, and after installing, they overload the system by adding more appliances. Doing this will cut short the hours the inverter is supposed to run.

Solar system for a home with 32inch TV, 1 fridge, 2

For this simple home setup, I'll assume the TV will consume 120 watts of power, the fridge will eat about 300w, and the consume 45w each, making 90watts. Total watts consumption is 510 watts in this case.

It's important to oversize your system slightly to avoid human errors, like overload. A 1KVA to 1.5 KVA inverter is okay to power them conveniently.

Solar installation explained

Running 510 watts of appliances on a 2.5kw battery will give you about 5 hours of backup running only from the battery. But when solar panels are added to charge the batteries during the day, and the solar panel's total rating is higher than the battery kilowatt, then the battery gets fully charged during the day.

The loads will run from the excess power from the sunlight, keeping battery usage until nighttime. MPPT can do a better converting excess voltage to usilize while the sun is still shining.

You'll have longer hours running your solar system when a solar panel is added. Your loads will run directly from the batteries at night.

MMPPT vs PWM charge controllers: Which is better?

The PWM controller is cheaper but doesn't deliver the total power/amps coming from the solar panels. The MPPT(Maximum Power Point Tracking) is mainly used for larger systems, it's used for tracking the maximum power point of solar panels.

The MPPT constantly adjusts its operating voltage and current, making sure the solar panels deliver fully. The MPPT is more costly because of the components it's made of.

With the amps test, I did, using the same solar panels and rating, the same battery KW, the same cables, connecting them to a PWM and an MPPT charge controller, the MPPT always delivers higher amps.

Reduce loads to enjoy more solar energy at night

For a user to maximize his or her solar energy system to last longer, he or she must minimize the total energy/watts consumption when utilizing the power from the battery, mostly at night.

Best solar panels for installation in Nigeria

We have three popular panels in the market this day. The monocrystalline, the polycrystalline, and the thin film. The most advised solar panel to use is the monocrystalline solar panels because of their high efficiency and their better performance in low light conditions.

Man installed solar in his house

Meanwhile, Henzodaily.ng earlier reported that a young Nigerian man, @kanisuru7, shared a video of the house he completed. The moment he started the building project was captured on camera.

The TikTok clip showed the moment the building was at the lintel level and woodwork for the roof was about to be done. After the roofing was done, he installed solar panels on it for constant electricity.
