Featured0:35Solar Inverter Won't Turn On? Fix It in 5 Minutes (2026 Guide)
Maintenance & Issues11 viewsAug 5, 2026
A dead inverter screen looks like an expensive problem. Often it isn't. A tripped breaker, a grid dropout or a DC isolator someone knocked off during maintenance will all produce the same blank display as a genuine hardware failure — and all three take minutes to rule out. Before that, one thing matters more than any of it: solar strings carry lethal DC voltage whenever there's daylight on the panels, regardless of whether the inverter is running. Nothing in this guide requires opening the casing, and nothing should. Everything here is limited to switches, breakers and reading what the display tells you. Dead screen or blinking fault light? Run these safe checks before you pay for a service call. Many inverter faults clear in five minutes.

0:35Installation & SizingHow Many Solar Panels Do I Need? The 2026 Sizing Formula
Ask three installers what size system you need and you'll get three different answers — usually before anyone has looked at your electricity bill. That's backwards. Your bill already contains everything needed to work out the right system size, and the math takes about two minutes. Get it wrong in one direction and you're still importing expensive units from the grid. Get it wrong in the other and you've paid for panels that will never earn back. Here's how to size it properly, with a worked example. Read your bill, find your daily units, and translate them into the right number of panels and inverter size — the 2026 way to avoid over- or under-buying.

0:35Installation & SizingRooftop Solar Layout Mistakes That Cost You Energy (2026 Guide)
Most people spend weeks comparing panel brands and then hand the roof over to an installer without a word about layout. It's the wrong order. Orientation, tilt, shading and string grouping decide how much energy your system actually produces — and unlike the panels, getting these right costs nothing extra. A well-planned array on mid-range panels will out-produce a badly planned array on premium ones. Here's how to plan yours before anyone starts marking the roof. A smart rooftop layout beats a premium panel brand. Orientation, tilt, shade mapping and string grouping — planned properly for 2026.

0:35Brands & ReviewsHow to Compare Solar Inverter Brands in 2026: A Buyer's Guide
Every solar inverter looks the same on the shelf. Same white box, same digital display, same reassuring specs printed on the side. But the inverter is the brain of your system and the component most likely to fail first — and that's where the real differences show up. Price is the easiest thing to compare and the least useful. A brand with genuine local service support and a warranty that's actually honoured in your country is worth far more than the money you save on an unsupported import. Here's what to compare instead. The inverter is the brain of your solar system — and the part most likely to fail first. Here's how to compare brands properly in 2026.
