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 that. That in mind, does any of you guys have or have had a similar setup and how much did it cost altogether (incl installation) tax and all that will be different here but having a +-25% price tag would help. Also any other advice maybe?

Edit: the roof is south, so sun would be on high intensity the whole day. Especially in summer, the days are often very hot and long and almost no clouds

Solar Supports

Solar Supports I'm looking at installing a solar system at our off grid cabin this spring and I'm trying to come up with a good way to get the panels up high enough to catch decent sunlight. The roof of the cabin is not an option as there are some trees blocking it but I do have a shed that I figure I'd be able to brace the supports to, I can't use the shed roof either as it's facing the wrong direction. A couple neighbors have systems which they've put on poles that go up sort of like a street lamp or flagpole style support which is an option but I thought maybe either a frame like a scaffold kind of thing secured to the back of the shed might be a more sturdy option. What have you guys used to elevate your panels on a standalone frame, or have you seen any companies that sell good kits? I'm in BC in Canada as well. Thanks for reading. submitted by /u/dykehoncho [visit reddit] [comments] https://ift.tt/2C1elG6
