definitely curious about that early morning late afternoon sun reflected off water, not as much worried overloading cells capacity with the light fighting through some thicker atmosphere at those angles. the other than has me curious is solar film, apparantly theyve been making it for 5-6 years, but I havent seen anyplace to actually BUY the stuff.. its supposed to be a whole lot lighter, cheaper, and near the same kind of output, heck, I'd cover near a whole darn hull.. has me thinking they're just blowin sunshine up our skirts! "oh we're developing", "oh we're looking for investors", etc.. (but not for sale?!) yeah that light bouncing off the water would be useable and extend the hours charging or running, especially if running north-south-ish with sides facing. other day was searching for "flexible solar panels" only finding the amorphous, that only lasts 6-7 years, and not cheep. (darnit-darnit-darnit!) another member had mentioned seeing 400 at best from a 450 rated panel.. sounds about right with em CHEMTRAILING to dim the sunlight 10-15% or more (verified by NASA too) spending millions of gallons of high grade diesel, hydrocarbon emissions all the way.. to saturate everything with barium (Ba), aluminum (Al).. BAAL ya say? -and they got the "greenies" concerned about natural carbon Di-oxide! sheesh. carbon MONoxide (burnt and unburnt fuel) is toxic to life, so is micro aluminum. they've about shut down everything productive, so the demand for energy should be LOW, but they keep shutting down powerplants to keep demand and prices HIGH, gee thanks? and if they werent flying sorties to bombard us with the chemtrails, I'd think demand for and price of fuel would be a whole lot lower. (its not "conspiracy -theory-", its sabotage!) if anyone doubts it, just look UP to see ribbons in the sky hanging there forever, dissapating into hazy funk, or look at monsanto trying to develop aluminum resistant genetically modified crops that can grow fast with less sunlight, is the truth too!
(yeah, it IS bio-chemical attacks, denial propaganda, profiteering from sabotage, etc.)

One of the curiosities I have is in regards to solar power in the late afternoon sun when the sun and its reflections together span but 30-degrees or so between them. Visually (and based on my sunburns) it appears to often have more than two effective suns coming from the water alone. So I get to wondering if a panel pointed horizontally towards that solar melee would result in output exceeding the panel's rating by 1-2x. Is anyone else curious in this regard? -Myles From: electricboats@yahoogroups.com [mailto:electricboats@yahoogroups.com] On Behalf Of James Lambden

Subject: Re: [Electric Boats] curiosities The secret to tracking on a marine array is to have a solar cell on both sides of the panel, so the panel knows when the sun is behind it. Getting our array to track is our next project. We've bought all the equipment, just have to install it. Once I had my panel straight up, horizontal, and it was generating 20 watts. I moved it to point at the late afternoon sun, and it started generating 200 watts. At full output it is rated at 450 watts, but I rarely see it that high. I can get 400 watts pretty regularly most of the day, which will propel the boat at 3 knots in calm conditions, and double the boat speed while sailing in light wind conditions. Solar Sailing, especially with a tracking array, is incredibly fast compared to traditional sailing. Keep experimenting or contact me if you want more information on a marine articulating solar array. Propulsion Marine Products On Feb 20, 2012, at 7:06 PM, Lonner wrote:
On the subject of solar tracking: the photovoltaic panels I have tested showed very little or no measureable variation in output when moved 15 deg's (1hr) from normal to the sun's position. I have been working on a cheap tracker that would articulate once an hour instead of continuously to take advantage of this. If anyone out there can confirm the result with other panels, it would help move the tracker project off the back burner. I wonder if different types than multi-crystalline are more or less subject to alignment.

Even on land to use concentration you have to track the sun very accurately you have to be in alinement to the source 100% of the time, on a boat all these methods would be nearly impossible. The slight movement of a boat at rest would remove any advantaged of sun tracking not to mention under way.

Any company that has tried at small scale concentration has gone out of business pretty quick, on a boat these cost issue would be even greater. Try pricing three way tracking gear with enough persuasion to track satellite singles at sea this is the exact gear you would need to even attempt concentration at sea.
