rule # 1 of PV
efficiency% - cost of money % = return %
(1st order arox.)
so if you are the government or a bank that is 0.5%
for the rest of use we are lucky to get 5% LOAN.
wich would be a more effective and cost optimised solution to support a viable on going PV producing corperatons.
Now we give away millons and nextweek they clse the plant.
So we have ant-greeninstead of reen from our goernment green initiitivs.
