SunEdison developing home solar charging systems for Chevrolet Volt

SunEdison, a subsidiary of MEMC Electronic Materials, Inc., has joined the Pecan Street Inc. smart grid project. As part of its role, SunEdison will be leading development of the advanced home solar photovoltaic (PV) charging systems for the Chevrolet Volt.

Pecan Street Inc. is creating a consumer-focused smart-grid demonstration project in Austin, Texas, built around home applications, and consumer electronics. SunEdison joins other participating companies—Best Buy, Check-It, Chevrolet, Freescale, Intel, Landis+Gyr, Sony and Whirlpool—in deploying products and dedicating researchers to the project who will collaborate with Pecan Street Inc. and University of Texas researchers.

Deployments by member companies include one of the nation’s most highly concentrated residential installations of EVs, home services systems, smart appliances and charging of cars from home solar panels.

A number of the SunEdison-led home solar vehicle charging systems will also have in-home batteries, and all systems will integrate into the home services systems provided by other companies in the Pecan Street Inc. project including Best Buy/Check-It, Intel, Sony and Whirlpool. More than 150 participating residents will have rooftop solar PV, including nearly all of the residents who acquire Volts.

The information about how and when customers use energy supports the development of smart EV+PV systems that provide truly green transportation that does not replace carbon from tailpipes with carbon from smokestacks. The approach also efficiently supports services that are important to consumers and to controlling smart appliances.

While "SunEdison developing home solar charging systems for Chevrolet Volt" - Walmart closed out an e-bike at $200.

Harbor Freight has a 45 watt solar array, with battery controller, for $150 and $5 multi-meter.

Add $90 for a deep cycle 12 volt battery, $30 for 100 watt inverter, and a afternoon to assemble, solar array facing Southward and minimally obstructed.

Bingo - for under $500, 10 miles of daily fuel free EV travel for years(trouble-free months so far).

A optional $20 'Kill-a-Watt' meter is handy.

Like the ad - 'Just Do It'.

kelly - Excellent points...people are more easily convinced to change their behavior when they see how their pocketbooks are affected.

You should be able to charge the e-bike without an inverter. Just sayin'.

The battery pack is 24 volt. I could disassemble and charge each 12v lead-acid battery, but it's easier to use the charger and have 110 vac.

I will replace the ~$30+ batteries when bad, rather than pay ~$120 for the pack.

I problem is that I later bought a li-ion emoto bike for $500 on special. The lead-acid has to be charged after each trip for better longevity. The li-ion can run for over a week(2 mile trips to the mall) and has a built-in charge indicator.

Even with free energy, it's easier to be lazy.

The ICE/oil industry is getting vicious attacking the EV business. They see the handwriting and it says their oil empire is teetering on the edge of collapse.

Solar charger are great - but kelly's rig packaged up for low cost sale at Best Buy, Walmart or Target - would attract the next class of EV and PHEV owners. Certainly if you live in the sunbelt and drive a Leaf or Volt or soon, Model S Tesla, these home solar solutions make good sense.

You don't take the battery apart.  You charge a pair of 12 volt units in parallel, then re-wire in series to charge the bike battery. (Or 3 with a dropping resistor, if you need extra voltage to push the bike battery to full charge.

Not that you particularly need this now, but if either the inverter or AC charger breaks down it will give you another way of getting the job done.
