Yeah there is also a company in Holland who makes these they cost quarter to half the price but has only 500 watts. I'm going to talk to them on how I adapt this to the normal consumer. The other one has 3 times the power of a sunpanel with a 1.70 diameter. But I know you can put then also on your balcony or roof. But first I must speak to them in person. No no goals yet but I'm gonna be a whale sometime. 😆
