Solar inverter efficiency is a critical specification that directly affects the efficiency of your entire solar system. It is almost always a much more important consideration than solar panel efficiency.
All the power generated by your solar panels has to go through your inverter before you can either use the power in your home or export it to the grid (and get paid) so every percent of extra efficiency that you can squeeze out of your inverter will directly improve the performance and payback of your solar system.
So do you just need to pick the inverter with the highest “efficiency” number on the specification sheet? Well I’m afraid it isn’t quite that simple. (You guessed I was gonna say that didn’t you?!) [Read more…]
