Hello everyone,
I have tried to read up on the topic of photovoltaics but have so far barely gotten beyond very optimistic (Google) advertising offers. Here in the forum, I have mainly read critical (mostly older) posts.
About my concern:
We are currently planning a (gable roof) new building for early 2017 with south/east and north/west orientation and have so far followed the classic concept of gas condensing boiler/solar thermal with water storage. Through a colleague, I became aware of the topic of photovoltaics. When he told me that he can (theoretically) generate 3500 kWh/year with a system he bought for €7000 about 3 years ago (but without storage), I became curious.
I would like to know how realistic it is to achieve such a performance with an investment of about €10,000 and to use it completely independently? Currently, we live (3 people) in an apartment and consume about 3800 kWh/year. Of course, I quickly dismissed the idea of the "quick market"...
If at all remotely possible, I would appreciate literature/prices for such an undertaking.
