Envision Solar, known for its standalone solar charging stations, boosts San Francisco’s charging network by three units.

Might not seem like a whole lot. However this is part of a data collection program. As Envision Solar reports:

“Three of Envision Solar’s Electric Vehicle Autonomous Renewable Chargers (EV ARCs™) will be placed throughout the city at predetermined sites, each for a three-month time period. The mobile solar units will collect data on frequency and duration of use; the Driving on Sunshine team will evaluate usage reports at the end of the campaign, inform the City on its findings and will donate units to the host sites determined to have the most impact.”

And another!

And another!

This “Driving on Sunshine” campaign is a collaboration with the San Francisco Department of the Environment & Charge Across Town, who will facilitate this program.

Stat Update:  Each unit generates about 16 kWh in a day, which is stored via 22 kWh battery.  Cost of the units are said to be ~$50,000 and come equipped with solar tracking technology and a sing L2 charging connection.

Desmond Wheatley, CEO of Envision Solar stated:

“This is another milestone for our Company. The growing acceptance of our technology is being shown not only by our rapidly growing sales but also by events like ‘Driving on Sunshine’ which combine government support with community advocacy and consumer demand for clean energy solutions that make sense for today’s cities. We are hiring more local employees to keep up with demand and look forward to repeating this demonstration in other cities around the country.”

The Mayor of San Francisco, Edwin Lee, added:

“This program allows the City of San Francisco to demonstrate that electric vehicles can charge from 100-percent renewable sources and with no impact to grid operations, making better use of our energy supply. Driving on Sunshine also helps deliver on the solar and renewable energy goals paramount to moving the City away from fossil fuels.”

These independent solar charging setups are said to normally cost about $45,000, with a 30% government inventive, and these three in particular will be placed at the Stonestown Galleria Mall parking lot, the public parking lot at Embarcadero and Green Street, and a City CarShare lot at 17th & Shotwell Street.

“Envision Solar Installs Solar-Powered EV Charging Stations in San Francisco as Part of “Driving on Sunshine” Campaign.

SAN DIEGO, CA–(Marketwired – April 17, 2015) – Envision Solar International, Inc., (OTCQB: EVSI) (“Envision Solar,” or the “Company”), the leading renewable energy Media, Branding and EV charging product company, announced today the launch of the “Driving on Sunshine” campaign in collaboration with the San Francisco Department of the Environment and Charge Across Town. The program will sponsor free solar-powered electric vehicle (EV) charging in highly visible locations across San Francisco neighborhoods throughout 2015.

Three of Envision Solar’s Electric Vehicle Autonomous Renewable Chargers (EV ARCs™) will be placed throughout the city at predetermined sites, each for a three-month time period. The mobile solar units will collect data on frequency and duration of use; the Driving on Sunshine team will evaluate usage reports at the end of the campaign, inform the City on its findings and will donate units to the host sites determined to have the most impact.

Free EV charging is now available until June 30 at the following locations:
Stonestown Galleria Mall, Lakeshore District, parking lot D
The Embarcadero at Green Street, North Beach District, public parking across from the Exploratorium
17th Street and Shotwell Street, Mission District, City CarShare lot near the 16th Street BART station (available exclusively to City CarShare members)

Representatives from the City of San Francisco, the Port of San Francisco and City CarShare will join the Driving on Sunshine team today at 10:00 a.m. for a ribbon-cutting ceremony on the Embarcadero at Green Street. A second ceremony will be held at the Stonestown Galleria Mall at 1:00 p.m. Driving on Sunshine is funded by the 11th Hour Project, a program of The Schmidt Family Foundation.

Is there any published data on how much energy they can store in 24hrs and what rate they charge vehicles at?

Stimpacker

That array can put out around 14kWh a day in the month of May.

Not much to store and just 1 car can empty that in a day. So meh.

A real grid-tied solar carport works so much better. Waste of subsidies.

14kWh would work for designated parking places at work. That’s more than enough juice to go 40 miles.

Also airports, or anywhere cars sit for a long time.

Not to dismiss your question (I just don’t know) but eyeballing the picture leads me to think these are 300+W panels.
Using PVWatts http://pvwatts.nrel.gov/pvwatts.php
a ≈3000W tracking system in SF could collect only about 10- 25kWh/day (winter to summer averages).

Devil in the details of course.
(a) SF has notorious microclimates with plenty of summer fog in some locations. This might not be fully reflected in the climate data used by PVWatts.
(b) Plus an average doesn’t reflect the reality of a run of sequential cloudy/foggy days.

So with 1/3 of day’s production going into storage, the rest to charging, we would be charging 16kWh/day, or more in summer, and saving up to 8kWh for the next foggy/rainy day.

I’d guess ≈16-24kWh of storage and an L2 (3.3kW?) charging rate ( just to wear down people who might otherwise get a little too greedy).

Be interesting to know the actual answers to your questions though!

In a perfect world, solar would be situated where it is most efficient and electricity would be used only when needed. It is not a perfect world. If you cannot put up solar elsewhere but for some open parking area, and you park regularly in that parking area, and you need the daytime charging, then this makes sense. However, it seems like those are a bunch of “ifs” to have to check off and a shame that one has to create otherwise-expensive solutions on the ground to get around a piece of paper (like electrical purchase from a preferred renewable energy provider) that would otherwise suffice.

Maybe I missed it somewhere, but what’s the motivation for a mobile charging station in the first place (*) ? They’re presumably more expensive than fixed ones to build and transport… If it’s a PR move, PR for what? EV owners presumably know where thet can/can’t charge their cars. If it’s to collect data, data for whom, on what? Data from a mobile station on 3 months use doesn’t seem like it woulkd be representative — it takes a while for usage patterns to settle down.

(*) The practical motivation would be for charging at events: Festivals etc. where the normal population isn’t large enough to justify a station. But that’s not the use case here.

WOW! $50K = Overpriced!
Let’s see.
Two Tesla Powerwall = 20 kWh = $7K
EVSE = $1K (generous here)
That leaves $42K for solar panels, solar tracking technology and hardware. Someone wants to sell an egg for a million dollars instead of selling 1 million eggs for $1 each.
I’m guessing they could sell each for $35K and still make hefty profit.

NPNS! SBF!
