The CdTe layer used in cells today is about 1/50th the thickness of a sheet of paper, or roughly 2 m, and its sealed up tight between two thick glass sheets.
Crystalline silicon (c-Si) is king today, with 90 of the global PV market, and I believe it will continue to dominate for at least the next decade.4 MIT Future of Solar Energy Study, 2015, in preparation.Lets focus on PV for now.Easy TO play, easy TO WIN - brinmile TO your members dile!Dollars and are approximate conversions.S.We refer to these non-module costs as balance-of-system (BOS) costs, and in many ways, theyre harder to reduce than module costs.Well, your solar electrons arent competing directly with the grids electrons on cost.Electricity demand with solar PV at average solar insolation levels, we would need on the order of 50,000 square kilometers 4which sounds like a lot, margaritaville apparel coupon code until you find out that we currently dedicate 100,000 square kilometers to producing corn ethanol satisfying only 10.S.A solar cell doesnt really care where photons come fromwhether scattered from a cloud or transmitted straight through the atmosphere.So whats stopping solar from taking off?
I encourage you to read the report when its released later this year (and others) and come to your own conclusions about the future of solar.
Scaling: Materials and land use The land use issue is actually not that big a deal.For any given electricity grid and cost of PV, there will likely be a natural break-even point for solar penetrationabove that level of deployment, additional solar generation will no longer be profitable, and further investment in solar is unlikely.Dollars based upon Bloomberg's conversion rates.Just to be clear, the views expressed here are my own.Todays technologies (mostly crystalline silicon PV) canand likely willscale up to multiple terawatts of capacity worldwide by 2030 without any major technological advances.And even though current technologies will likely plateau at some minimum sustainable cost floor, its clear that there are many new and exciting solar technologies in the pipeline, with many new and exciting applications to come.For solar PV in particular, its important to note that the total system cost is no longer dominated by the solar panel itself.Solar-Powered Camel Clinics Carry Medicine Across the Desert.After a solar PV system is installed, it costs almost nothing to operate.Silicon PV is abundant, efficient, reliable, and proven, but it absorbs light poorly.
Its basically a subsidy for solar and a great deal for you, although utilities dont like it because youre not paying your share of the grid upkeep.
