Hello,
a friend of mine lives in Palm Springs, which is a prime solar area. I read a lot (am from Germany, which went through a heavy cycle of boom and bust of solar - thanks to 1st very generous subsidies - feed in tariffs - that 2nd were cut down drastically. That was wiping out most of our solar equipment production and new installations. A new residential installation here is now around 1.2 €/Wp - and still the installers and owners make a - though small - profit)
I read about net metering and the upcoming net metering II. About GEC and EGC, firefighters' standoffs,..
A few questions remain:
By what metric does the 10kW size limit for residential PV get measured? STC PTC inverter DC rating inverter AC rating......?
Why are in the US the very expensive high power panels so popular (LGs over 300W, SunPower, Panasonic ....) when good quality panels like Hanwha, Winaico, Aleo are much more economic? If space is at a premium and the generated electricity is very valuable there might be a reason. But most of the time there's enough area.
What are the reasons for the very high labour costs for the installations? We have constructed 40 GWp, and a 2 worker team installs a 10kWp system in 1 day for 1000 to 1200 €. There has to be 1 craftsmaster roofer and 1 craftsmaster electrician (journeyman is not enough by our laws). Of yourse the company has some margin on the equipment (panels, inverter...). A well organized company has 2 teams erecting 8 to 10 systems a week - and makes a good profit. Our health and safety regulations are very strict - as are all our rules and regulations.
Thanks
Michael
