The sun is in our DNA

The annual energy yield of a typical 100 square meter Calpak solar system is 80,000 kilowatts. The total energy cost that can be saved in the 25 years of expected operation of such a system is 220,000 euros. The investment required to install it has an annual return of more than 30% and payback in 3 years at most – not including a possible subsidy that will significantly reduce the expense.
