The government determines for each property the dimension of solar duty. By the furtherance, there is a highest price, where the system is cost neutral for the new house owner.
Is no company ready to deliver the equipment for the solar duty for the maximal professed price, the department of construction has 4 weeks time for an offer for a fulfillment of solar duty.
Is the department of construction also not able to get an offer at the requested price, the new house owner is liberated from the solar duty. The solar industry has to decide between small market with apothecary prices or huge market with decent prices.
boycott and boycott breakers
Naturally, there will be a lot of companies boycotting the solar duty in the first time. They will tell, this price is impossible. It's clear a photovoltaic sales man demanding 5000.-EUR kW peak despite new built most modern photovoltaic factroy can not live with the same system sold in Austria for only 3000.-EUR per kW peak or the house owner is liberated from the solar duty.
But I expect at the new thin film producers, enough companies being enthusiastic about the new market.
