Rarinn's Ideas

I noticed that photovoltaics are really cheap now. 19.8 kW of peak power would cost around 20 000 PLN (1 USD is equal to 3.65 PLN when I am writing this). Array of 44 of those, with peak power of 475 W each, which actually will be closer to 450 W, because of marketing and degradation progressing with time, will produce aforementioned amount of total peak electrical power. I accounted only for the initial fast degradation, it will slowly get even worse. Appropriate hybrid inverter costs 11 000 PLN.

  To convert solar energy into electricity that will be later used to produce ammonia ( electrolyzing water and Haber–Bosch process ) I propose that photovoltaic thermal hybrid solar collectors (PVT) with compound parabolic concentrators (CPC) mounted on dual axis trackers should be used. cpc_c.ods is my attempt to describe basic parameters of CPC with high-school math (to achieve best results ray-tracing and realistic models of irradiance at various conditions should actually be used).
