Solar systems don’t usually fail suddenly without a reason. When a system works perfectly one day and stops the next, it almost always means something has changed—sometimes small, sometimes hidden, but always important. This article breaks down the real reasons solar systems suddenly fail and how to identify them quickly. 1. Battery Voltage Dropped Overnight…
One of the biggest mistakes in solar installations is oversizing one component and undersizing another. Many systems have big batteries with weak panels, or large panel arrays feeding small battery banks. Either way, the system will underperform and fail early. Balancing solar panel capacity with battery size is critical for performance, battery lifespan, and customer…
When a solar system fails, the client usually blames the installer. But as a professional, your job is to diagnose the fault—not guess. A proper system audit helps you identify the exact cause of failure, avoid wrong assumptions, and restore the system quickly and correctly. This guide walks you through a step-by-step framework to audit…
As a solar installer, your reputation is built on one thing: delivering a system that works perfectly. But even the best installation skills can’t save a project if the components supplied are fake or substandard. The sad truth is that the Nigerian solar market is flooded with imitation panels, cloned batteries, and fake inverters that…
One of the most common reasons solar systems fail — especially in Nigeria and other African countries — is panel–battery mismatch.Many systems that “refuse to charge,” “charge slowly,” or “kill batteries early” are victims of wrong panel voltage, wrong current, or wrong total watt capacity. As a solar installer, knowing how to detect panel–battery mismatch…
Running a small shop on solar is one of the smartest investments you can make—zero noise, zero fuel, stable power, and predictable running costs. But the biggest challenge for most shop owners is knowing the right panel size, battery capacity, and charge controller rating. This guide breaks it down into simple, practical steps, with examples…
Sizing solar for a water pump looks scary at first, but it’s just a few clear steps: find the pump’s power use, decide how many hours per day it should run, account for system losses and surge currents, then divide by the energy each panel delivers. Below I walk through the exact formulas, worked examples…
A solar inverter is the heart of your solar system. It converts the DC electricity from your solar panels into AC electricity for your home or business. When it malfunctions, your system may underperform, shut down, or even damage connected appliances. The good news? Many inverter issues are simple to troubleshoot if you follow the…
The dry season in Nigeria brings bright sunshine, but also high temperatures, dust, and harmattan winds. Many solar users expect maximum power during this period, but often experience low output, slow charging, or system malfunctions. These issues are usually caused by common mistakes that can be avoided with simple preventive measures. 1. Neglecting Regular Panel…
The dry season should be the best time for solar energy — bright sunlight, clear skies, and long sunny hours.Yet, many people complain about poor charging, battery drain, inverter shutdowns, or low power output during this period. Why? Because heat, dust, and poor maintenance habits reduce solar efficiency drastically. This guide exposes the top mistakes…
