Complete new solar array for a house. Question regarding panels Hi, first the location, Italy, 42N. The house is in the mountains on approx 600m above sea. I’m thinking of buying some panels, I have 15-20 sq meters roof. Now the other thing is, if I use 15 sqm combi-panels or part it up in idk. 20% thermo and 80% photo panels. I know that photo panels need to be as cool as possible and thermo need to be hot, therefore combi seemed like a bad decision to me due to loss of efficiency. (I read that 50% loss are normal). Since it’s in Italy, and we also have a gas heater, warm water for showering isn’t needed all the time, that’s why I would prefer power over warm water so much. I don’t have an idea on pricing yet, because most local shops only give you an price estimate if you go there and ask. I would want to do that in a local shop, because it’s in the countryside and people tend to be more eager to help if you buy everything first hand from them, also supporting local economy and all...
