“Historically, we’d been taught that solar modules were the most precious of goods – to be held closely, to be loved. There’s that famous graph showing the price per watt falling from $100 in the 1970s, to the less than 30¢/watt these days. Now, we still care greatly about our solar modules – however – we use them differently as the facade of ideology falls in the face of modern knowledge.
Solar FlexRack has announced that Swinerton Renewables has contracted its GX-3 fixed racking system for a 26.4 MWac solar power system located in Simsbury, Connecticut. The Tobacco Valley Solar Project was developed by Deepwater Wind, who signed a long term power purchase agreement (PPA) with Eversource of Massachusetts. The PPA suggested that the solar power plant would receive payments for both the electricity and value of capacity (like all major utility scale solar plants are paid these days).
The most interesting part of the design in the DC:AC ratio though – a very rough public filing at the end of May (see page 19 pdf) – suggests over 48.6 MWdc of solar power, versus the publicly announced 26.4 MWac.
The blurry public document shows a portion of the project will be greater than 84,000 400-watt solar modules, plus 38,000 395-watt modules manufactured by Jinko, though the model number couldn’t be found. These numbers total 33.6 MWdc of 400-watt, and 15 MWdc of 395-watt modules – totalling 48.6 MWdc. No mention of energy storage could be found in any designs.”
