For those EVers that haven't delved into solar PV yet. The sun makes up to, but rarely more than 1200 Watts per square meter of area. Sunpower who makes about the best commercial panels is about 20% efficient. You have to be aimed within 30° of the sun to get the full power from it.
The arithmetic is pretty easy to do from there. If we call that panel set 2 Meters^2, then you have a potential of about 0.2 x 2400W = 480W. Just for estimating's sake, what will a car take for a trip in its range? 10kWh? That panel would have to get full sun for 20 hours. Maybe three days in a sunny place There are a lot of ways to cook these numbers and the new flexible Sunpower panels are quite interesting. This will be able to help out, but not fully charge. It could offset heaters in the winter, AC in the summer, run a battery heater even, add more during a charging stop, save a little money, but not much. It is better than I expected when I first started to do the estimate - these are sweet panels. -------------- next part -------------- An HTML attachment was scrubbed...
