I have heard good things about Positronics, so that covers the most important decision for buying solar: Who Should I Buy Solar From?
Quality products, price is fine. I don’t have a strong opinion on whether you should get the higher wattage panels or not. However, if it’s not a financial stretch, the TwinPeak do seem enticing
Would love to see a photo of the install once it’s up.
I’ve read your entire series of helpful starters, they are gold to us newbies, you should be congratulated for your time and effort in making it easier for us to understand. I too, like the TwinPeak option, and for sure provide some pics.
