Hi Robert and All, Just 3 of those would power my tiny retirement home and lightweight EV's for 25 yrs for $500 in panels offgrid! Since it is a 34' trimaran in Fla it's perfect as my main load, A/C, follows solar output near perfectly. And it has E- drive . One reason to finish the E woody and generator was to go down to see sunelec and these lams as 250 miles away. I don't mind building frames, junction boxes at those prices. Though they are 72vdc nom. I see prices have dropped again as they are offering full 3-10kw gridtie kits with UL panels for $1.3-$1/wt! Just have a local electrician to permit, install. Payback most everywhere would be 2 yrs or 50% ROI/yr for 25 yrs!! Where else are you going to make that interest? EV's getting cheaper, better batteries now very low cost solar to power them. It's what the Saudi's are so worried about they said 35 yrs ago would happen if oil prices got too high. They held the line on prices for 20 yrs until demand outstripped supply. Now with the tiny 1% surplus causing this price fiasco they have power again for a while, not longer than 2 yrs as the economy will recover because of lower oil prices. One thing on installing solar, Don't do it on the roof unless no other choice. Instead make a carport, patio, lanai, shed, awnings, fence as Robert mentioned, etc makes it easier, cheaper to install and has added value too.

The reason I mention these solar panels on the EV list is because these are without frames. Maybe easier to mount on a truck?
http://sunelec.com/solar-panels/sun-435w-laminates-grade-b.html Here are some 435 Watt solar panels (81” by 41”) that are only 39 cents a watt compared to home solar panels down to about 55 cents a watt (were $4/watt when I got my first ones 4 years ago. That is a 10-to-1 reduction in just 4 years. Meaning they are only a fraction of an inch thick instead of having a frame that is 1.5” thick. So they could mount flat to a vehicle IF you had almost 7 feet by 4 feet of flat surface. Doubt they would be any good on anything but a truck. But the price is amazing. I think they do not have a connection box, and hence the low price. You have to dig out the laminated contact strips and solder to them (and you must include the three bypass diodes too). P.S. I do NOT lament the fact that I paid almost 6 times as much for standard panels only 4 years ago, because the difference has already been made up in 4 years of free electricity. This is an important concept for solar. It make no sense to wait. At any given day’s lowest prices, the future lower prices will be made up for by all the free power you get instead of waiting. And already solar panels are cheaper than windows of the same size, so they just cannot get much cheaper… And you stop burning fossil fuel the day you turn them on. P.S. From the same supplier in Miami, they even have panels as low as 24 cents a watt. But these are the low efficiency ones, so you need about 2.6 times as much space for the same power (but at half the cost). Only useful if you have unbelievable roof space. P.P.S. One person suggested these last panels are not much more than the cost of a FENCE. And so his HOA prevents him from putting up any fence to shield him from his a$$ of a neighbor, but the state does not allow an HOA to block solar panels. So this guy said he would gladly buy the panels just to block his neighbor and the power would just be free on the top! P.P.P.S. Amazingly covering the curved roof of my prius cost $10/watt in 2008 almost 20 times as much. But the only way to do that is with smaller 1’ square modules and these (non-home style) have not changed in price hardly AT ALL in the same 7 years! They still cost about $10/watt. Meaning all the cost reductions in solar are simply due to volume production and that, only for home and commercial sized panels.
