Solar Guides

Panels and inverter get all the attention. The cables and protection between them decide whether your system is safe.

An inverter datasheet has fifty numbers. About eight of them decide whether it suits your home. Here’s how to read them.

Homes use most power at night. Businesses use it in the day, exactly when panels produce. That makes solar especially good value.

Two inverters working together can beat a single big unit, but only if they’re set up correctly. Here’s when it makes sense.

A beeping inverter isn’t always a broken inverter. Most warnings point to something simple you can check yourself.

Panels don’t suddenly die at 25 years. They slowly lose a little power each year. Here’s what that looks like in real numbers.

Earthing is the cheapest part of a solar system and the one most often skipped. It’s also what protects your inverter in a storm.

Two batteries with the same kWh can last very different lengths of time. Depth of discharge and cycle life explain why.
