County of San Diego selects Envision Solar EV ARC solar charging stations
07 August 2018
The County of San Diego, California will deploy Envision Solar International’s EV ARC product at the County’s Department of General Services to provide emissions-free EV charging to its electrified fleet vehicles.
The EV ARC product is completely solar-powered and grid-independent. EV ARC products also provide the County with a disaster preparedness solution which will continue to charge vital fleet vehicles during blackouts or other grid interruptions.
The EV ARC products’ emergency power panel will provide first responders with a reliable and clean source of power during disasters or when grid power is not available.
According to the US Census Bureau, there are 3,007 counties and 19,354 cities and towns in the United States. Envision Solar considers the local government market to be an important area of focus for our sales team. The Company has deployed EV ARC products for the California counties of Marin and Fresno, as well as cities like New York, Los Angeles, San Francisco, Pittsburgh, Long Beach, Boulder, Sacramento, Santa Monica, Santa Cruz, Indio, Maywood, and others. The Company’s municipal and county pipeline is expanding.
The EV ARC fits inside a parking space without reducing available parking and generates and stores enough clean solar electricity to power up to 225 miles of EV driving in a day. The system’s solar electrical generation is enhanced by EnvisionTrak, which causes the array to follow the sun, generating up to 25% more electricity than a fixed array.
The energy is stored in the EV ARC product’s energy storage for charging day or night, and to provide emergency power during grid failure. The EV ARC product is a permanent solution but because it requires no trenching, foundations or installation work of any kind, it is deployed in minutes and can be moved to a new location with ease.
EV ARC products power Level I, Level II and DC Fast Charging and can work with a customer’s existing EV charging service provider.
Oh, look, an off-grid system put right in the middle of the grid.
What are the users supposed to do if the day is cloudy, or several days? Not charge vehicles? Not do the essential driving for their jobs?
Having reserve to keep the pack charged means excess generating capacity, which goes wasted. So much battery capacity would be perfect for levelling the "duck curve", but without a grid connection there's no way to use it for that. This scheme reeks of pointless virtue-signalling and wasted potential.

Price per kWh could be varied automatically according to forecasted energy availability, let's say from under 10 cents to over $2.00 + per kWh. This could greatly reduce the size and cost of the battery storage unit.
A standby FC generation clean power unit could be added for extended periods with low sunshine.
