I came across a blurb about solar tiles and solar shingles, caught my interest because I thought I remember back some 30 years ago about some company that was going to develop something along those lines.
While checking into this I came across a site called Solar Power World, their web site is solarpowerworldonline.com. It has a lot of interesting information. When I searched their site for Renogy, it came with a few articles, did not know that Renogy is a Solar panel manufacturer, I thought they were just a reseller.
I wonder how long it will take to develop a 12"x12" solar plate, that will be at minimum, 100W, 10Amps production. Will produce a 100% @ optimum, and produce 80% at less than optimum (cloudy condition). Anyway, just my thoughts for the day.

[...]I wonder how long it will take to develop a 12"x12" solar plate, that will be at minimum, 100W, 10Amps production. [...] 100 watts at 10 amperes is 10 volts. Why do you want solar panels that work at 10 volts? |

Just thinking, 2 x 12" plates, connected in series, would be 20V, 100W, 10Amps. Lets say premium sunshine space is very limited, so, you could have 10 x 12" plates, 5 pairs connected in series. The contraption would be 24" wide and 48" long if arranged in two columns.
The power production would be, what.
I think the next step for solar panels should be, improve the technology so you could achieve 90% efficiency in cloudy conditions, then try to reduce the size of the panels.
I have also been casually trying to keep track of solar panels that produce hydrogen. It seems that there should be a better way of storing energy other than batteries.

If you have any ideas and MOQ, we can also help design and provide solutions. Give us an email or a call (techsupport@renogy.com) or TEL: 1(909) 287-7100. |

100 watts at 20 volts would be 100 / 20 = 5 amperes. It would be nice if we could adjust the laws of physics.
100 watts at 10 volts for 10 amps.
or
100 watts at 20 volts for 5 amps.
You can't eat your cake and have it too.
10 amps at 20 volts = 200 watts.
Sunlight, at a good location for solar power, is about 1000 watts per square meter. There are about 10.76 square feet in a square meter. So, 1000 watts / 10.76 square feet = 92.94 Watts per square foot. At 12 volts that comes to about 7.74 amperes at 100 % efficiency. 10 amps at 12 volts or more from a 12 inch by 12 inch panel isn't possible from planet earth.
