One of the first questions I hear when someone wants to install solar is: “Which inverter should I buy?” And most people already have a number in their head. “Give me 5kVA.” “Give me 10kVA.” “I want a hybrid inverter.” But choosing an inverter shouldn’t start with a number. The right inverter depends on what…
One of the complaints I hear from solar customers is: “Engineer, I bought 550W panels. Why am I only seeing 350W or 400W?” Sometimes the customer is genuinely seeing lower production because something is wrong. But sometimes the panels are working perfectly. The problem is that many people think a 550W solar panel should produce…
I’ve seen customers spend a lot of money on solar and still complain that the system isn’t doing what they expected. Sometimes the problem is the inverter. Sometimes it is the battery. Sometimes it is poor installation. But quite often, the problem started before any equipment was purchased. It started with the system sizing. A…
There is a sentence I have heard many times in solar: “This is the exact system we installed for another customer. It worked perfectly, so let’s do the same thing here.” It sounds reasonable. Why reinvent the wheel when somebody else has already done it? The problem is that solar systems are not templates. A…
Whenever I see a solar installation for the first time, I don’t start by asking: “Which brand of inverter is this?” The brand can be good. The panels can be good. The battery can be expensive. And the system can still be poorly designed. What interests me is how everything comes together. Because a solar…
Let me start by saying something clearly. Not every solar installer in Nigeria is dishonest. There are many excellent installers doing serious work, designing systems properly and genuinely trying to give their customers value. But there is one statement I have heard far too many times in the solar industry. A customer asks: “Will this…
I know that title sounds a little dramatic. But if you are about to spend hundreds of thousands or even millions of naira on solar panels, I honestly think you should pause for a moment. Because one of the biggest mistakes I see people make is buying solar panels first and trying to figure out…
If you’ve installed solar systems long enough, you know the nightmare scenario: a system looks perfect on paper, but when it’s under extreme load, it fails. Batteries drain too fast, inverters trip, or panels don’t supply enough energy. I’ve faced this challenge countless times, and over the years, I’ve developed a method to build solar…
As an installer, I’ve seen this scenario too many times to count: “The inverter is big enough. The battery is sufficient. Why does it trip when the AC starts?” The truth? Most installers — and even experienced electricians — confuse load with surge. And this is one of the main reasons “perfectly sized” systems fail…
Every experienced solar installer will agree on one thing:fixing another installer’s system is often harder than starting from scratch. On paper, it looks simple—identify the fault, replace the bad component, and move on. In reality, inherited solar systems come with hidden problems, undocumented decisions, and assumptions that make troubleshooting frustrating and time-consuming. 1. You Didn’t…
