We took these https://solarbuildermag.com/residential-solar/hello-lumin-get-to-know-this-nifty-smart-circuit-energy-management-tool/ - look in this store. I was very pleased with the quick installation, the capacity of work, and in general the appearance, which was also a decisive factor for me. For example, I didnt want such panels to spoil the roof of my house or its appearance. Now I am rich in solar energy, I can sell it to my neighbors, and I have become known throughout the area thanks to this very generous investment of mine. I think that's enough.
