Sunrgi recently made an impressive claim at the National Energy Marketers Association’s 11th Annual Global Energy Forum in Washington, DC: They say that their system will soon be able to “produce electricity at a wholesale cost of 5 cents per kWh (kilowatt hour). [A] price competitive with the wholesale cost of producing electricity using fossil fuels and a fraction of the current cost of solar energy.”
They do it with Xtreme Concentrated Photovoltaics (XCPV) by concentrating the Sun’s light close to 2,000 times (!) into extremely efficient solar photovoltaic cells. Part of Sunrgi’s patent-pending technology has to do with the cooling of the solar cells, dual-axis sun tracking, and the way the whole system is optimized for mass-production.
Not only are Sunrgi’s solar power systems more efficient compared to regular PV, but they also take much less surface area for the same power output.

Isn’t a miracle how Solar Energy is becoming so unique and well-known? Who would’ve thought Solar Energy would be this big? It’s nice to see society start to come around to Renewable Energy.
