Ford, SunPower partner on rooftop solar for EV owners

By | August 10, 2011, 8:59 AM PDT

In an attempt to further reduce the price of owning an electric vehicle, American automaker Ford and solar systems provider SunPower said on Wednesday that they would partner to offer customers of Ford’s Focus Electric car a rooftop solar system intended to offset the electricity required by the vehicle to run.

Under the “Drive Green for Life” moniker, the companies are trying to push the sustainability side of an EV — and perhaps calm fears that EV ownership will send electricity bills through the roof. (Even as the gasoline bill disappears.)

It’s also a way for SunPower to directly target customers who are most likely to be receptive to installing solar panels on their home’s roof.

The product in question is a 2.5-kilowatt rooftop solar system made of SunPower’s E18 Series solar panels. SunPower says they produce an average of 3,000 kilowatt hours of electricity each year, enough to handle about 12,000 miles of driving a year, the national average. The system includes a digital monitoring system.

The price tag? A cool $10,000 after federal tax credits (but before state and local rebates). But that’s the price to play in residential solar, and if you’re a brand-new EV owner who just spent some $30,000 on a new car, perhaps you’re interested in closing the loop.

SunPower says it will get in ouch with interested Focus Electric customers and make a house call to begin the process. It says its system will also be compatible with the C-MAX Energi plug-in hybrid electric vehicle Ford plans to roll out in 2012.

Still too expensive.
And, for the $10,000 cost of driving 12,000 miles in the electric vehicle using the solar panels, I can drive my gasoline powered 32mpg car around 80,000 miles. If you want to convince me to go electric, you're going to have to beat that. I can barely afford to drive as much as I want to as it is. sad

It's not $10k per year, it's $10k to install
The PV panels will generate the 3000kWh (or whatever the figure is) every year for the next 20-25 years. So the $10k installation costs need to be spread across that period (with some maintenance like replacing the inverter after 10 years or so, if you need one for a car charger?).

I do have some questions -

I have some trouble believing the 3000kWh figure from a 2.5kW panel array, unless it's located in NM or AZ or similar, but even at 2000kWh it would significantly reduce driving costs.

If you don't store the generated power you need the car or at least a battery pack plugged in. Since the battery pack is probably half the cost of the car you are unlikely to have two. So do you work from home? Is this only for cars that stay at home during the day? Do you work only at night?

Or maybe not too expensive...
You need to understand that gasoline prices are artificially low due to major subsidizing. You would not get the same figures if you paid $10 a gallon for gas or more, like they do in Scotland. I am very fortunate to get a discounted EV charging rate of about $0.025/KWH and so my monthly bill for driving about 32 miles per day, 5 days a week is $6. If the discounted rate went away, it would rise to about a $17/month bill. Hard for me to justify going solar at those prices too, but I would because gasoline, coal, nuclear and other forms of energy all have their disadvantages to solar. Once paid for, the panels are good with some maintenance for a very long time. Your grandkids might thank you for thinking more about the long-term impact.

considering that my car is at work all day, not at home, this would be
almost useless.
it would maybe help run the air and fridge when at work, but without a battery system it wouldn't help my car any.
if it does have a battery storage system included, that would be another expense down the road.
just not ready for that yet.
sorry, i'd like to help, just can't see it happening right now.
happy

Waiting for solar array as part of the car....
....with the inkjet technologies being used to create solar panels, it seems like one goal would be to apply solar panels to the roof and trunks of the car, so no matter where you go, the panel would be there with the car. Probably years away on this one, but certainly worth pursuing....
