Envision Solar starts work on parking area solar array in California
Oct 21, 2011 - US-based Envision Solar International Inc (OTC:EVSI) said Thursday it had started construction of a parking area solar array charging system as part of a showcase project in California.
The contract for the project came from a Californian utility of which details were not disclosed. The installation will include Envision's Solar Tree parking area solar structures, electric vehicle charging stations and energy storage units, the company said.
The Solar Tree system's output is 20-25% higher than that of conventional fixed solar photovoltaic (PV) systems as the solar panels follow the sun throughout the day, according to the manufacturer's calculations. The produced power is used to charge electric vehicles, while any extra amount usually goes to the power grid.
