This is a cross post from my other blog, Bleecker Mountain Life.
I've been calculating our planned home's energy needs. What I've come up with is a need for 50 245 watt solar panels. That's a lot of panels, and a lot of real estate. I remember reading about new technology last fall, but for the life of me I couldn't remember the name of it. Well, I found it. It's V3Solar.
One problem with flat solar panels is that they're rarely optimally positioned unless you have an expensive tracking system. The performance of photovoltaics also decreases with heat. V3Solar has come up with an ingenious way around both of these problems, and are claiming their system yields an astounding 20 times more energy from the same number of cells.
Rather than me describing it, watch this video. Prepare to be amazed.
If it's truly 20 times more efficient, that means that I'd need 20 times less panels. I could get by with three of these. They even have "trees" to mount these things on to take up less space.
Probably scare the crap out of the chickens, though. And my neighbors in Bleecker would think aliens moved in.
Now, think of applying this technology to your boat? Mounting big, flat solar panels is a problem. Instead, you could mount a small one of these along with all the rest of the crap on the back of your sailboat, or on the upper deck of your trawler.
Cool stuff Dave...
ReplyDeleteHey Dave - we're thinking of adding solar to Winterlude, but from what I was reading, it appears these are 3 meters by 3 meters? Not good for sticking on the top of our arch? Or am I missing something? I can see it for a trawler, in fact, if we switch, we might add ONE for all our energy needs! We figure 450 watts a day will do it, unfortunately we have 225 on Winterlude. :( THX! Jan

ReplyDeleteI'm betting that these things will be downsized quickly, especially for the marine market. I think this technology will be huge.
DeleteHi David, I've been totally enjoying your blogs and
ReplyDeleteI've been following the first since you and Pam were
wintering in Connecticut. I wish I could buy your
boat!
Concerning the PV generators you've found. I'd say things
that sound too good to be true likely are and physics
are physics. The fundamental facts remain: the solar
constant at the bottom of our atmosphere is on the
order of 1000 watts per square meter and solar cells
at best are near 20 percent efficient. The device you
found seems to act as a solar concentrator, a la a magnifying
glass over a burning pinprick. The 20-times increase
in efficiency that the website claims (which I find dubious)
is in terms of the photovoltaic area, not light collecting
area.
In the end, it's all about cost per watt. I hope this invention
performs as promised.
The electric energy needs that you're planning for your Bleecker homestead seems quite high, how many kilowatt hours are you using
monthly on average on Drifted away?
seem quite high.
Very Best Regards
