How much power do you gain back form these solar charging options?
if you're asking me, for my trike I bought 2 DM Solar's 145W panels because:Lock said:Watt are the "size" (and number of) your PV panels? And how many hours of daylight do you have... And can the panels be oriented to face and follow the sun?

A Toronto Hydro vulnerability study published last year warned that climate change could result in more severe freezing rain storms, increasing the risk of major power outages.
The study, published in September, 2012, says warmer winter temperatures can increase the intensity and quantity of freezing rain and wet snow, which can damage tree branches and overhead wires. Toronto Hydro estimates that about 26,000 customers were still without power on Friday, six days after a massive ice storm swept through Southern Ontario.
Compared to housecats and windows (not to mention habitat destruction from fossil fuel extraction and transport), solar thermal concentrators are still pretty far down the list of risks to birds.LockH said:An English friend might have said "Trouble Up the Mill" re solar concentration. "Emerging solar plants scorch birds in mid-air"

But I think it’s safe to say they don’t have anything to worry about from ebike-charging photovoltaics, whether roof-mounted or bike-mounted. The power concentration we use is in the form of LiPo’s, which seem to be dangerous primarily to the user, rather than wildlife. :wink:
Hey John, continuing the dialog. After visiting the http://cse.fraunhofer.org/ center in Boston and asking about the highest efficiency panels on the market, and their response that it was SunPower, I've wanted to buy some. Went online and found these: Semi-Flexible 120 Watt Solar Panel High Efficiency Sunpower, Marine Rated.John in CR said:Solar is becoming easy, practical, easily portable and cheap. Forget a genny. Then all you need is food, water, and a secure campsite, so you can go off exploring the wilderness on your ebike every day for extended periods. Traveling very light would be interesting in optimum weather with the right bike and a couple of square meters of fold up and store solar that doubles as part of your shelter. Then just keep going deeper and deeper into the wilderness or extended touring, and all you have to do is schedule extended relaxing stops during peak sun. Dogman lives in the desert but has been shooting down this approach for years, but I know absolutely it will work great. If I could get away from daily family duties for a while I'd love to prove it and just go. It sounds like you are planning exactly that, at least for weekend jaunts, so do it.
