What about countries that dont have any state support programs ? For example there is none in my country. I have already calculated, that it takes 8 years minimum to start getting profit from solar panel installment. 8 years is a lot. I dont think people even live more than 10 years in one flat, but those who do, usually are middle class or those who think 1000 times if they can afford to spend that much to install solar panels.
I agree - not everywhere there are comfortable financial conditions and state support. But conceptually - this technology, in the near future, will become available to a wider population, both in terms of availability, price, and ease of construction. I am very sorry that in your country the state has not yet come to understand that it is necessary to diversify energy sources, including through private solar "stations". I am sure that either the state will soon come to this, or private suppliers of solar panels will offer convenient financial programs - this is a natural development of the market.
