outstanding! this man never failed to impress me.. =)

Has anyone ever tried an idea of running water lines to cool off the panel and in turn provide house and air heating? Just thought of it and wondering if it works well...

Dont forget that to not help the temperature to go up even more on our dear planet, actually every solarpanel has to have a reflective surface in the same size as the solarpanel or bigger, reflecting the same amount of sunlight back into space..

were did you buy this panel?? 

we ive in the north & we see a major power increase when there is snow on th ground...

the thing is the sun moves and those mirrors dont move wont that affect the reflection back on the solar panels? just thinking if you was to fix mini mirrors on the sid of the panels????

@melkel2010 Quite the opposite, the cold increases the efficency of all electric devices. Solar panels operate increasingly better as temps decline from 70 degrees, and operate best in sub zero temps with clear skies and snow on the ground. Although there are fewer "solar hours" during the winter, the increase in performance due improved efficency will help compensate for the few "solar Hours" available. The extra cost of an MPPT charge controller is worth it if you live in the cold north.

@InTheSticks0001 Awesome info! I live near the 45th parallel in NY and am wondering how these perform in winter. I wonder if it gets very cold (near zero or sub-zero temps) will they lose efficiency? Electric wiring loses conductivity in the lower extremes.

Wouldnt the panel overheat or something

Wouldnt the panel overheat or something

wow thx

Thanks for the demonstration.  I've been told and it does make sense, that snow will do something similar. Fortunately it is cold stuff and lower temps increase efficiency as well.

does it shorten the life of panel?

There's a problem with this. To be useful you would need to put the mirrors in robotic arms to move with the sun?

Makes me speculate if adding light filters could provide as much or more benefit than mirrors alone. If you gather only the most useful wavelengths of light, you could discard the rest, thereby reducing heat (perhaps)--much the same as plants benefit from blue light for photosynthesis. Which wavelengths do PV cells "prefer"? Time for some research...

What is the best way to mount or place the mirrors? I don't feel like standing there all day.

wheres your hot wife lol

during very hot conditions. Surprisingly, solar panels actually lose efficiency if the cells get to hot

I don't think the added heat would hurt the cells but too much heat could definitely damage the EVA (ethyl vinyl acetate) the cells are laminated in.

what happen if you put magnifier glass?

Dan try frosting the PV glass; also painting it white-see if that lowers temp. and increases power. Last try installing some inexpensive comp. fans to the PV case, mabe the cooling effects will offset the energy use.Many thanks to you and your wife for your thought provoking films.

Dan, nice one, you could add plain white painted areas around the solar panel, as you know often used in filming / photography, a cost effective light reflector. If your into green engineering, just add another panel may not be the way forward.

You could build a simple border like a light oven with tin foil behind plexi glass would probably boost any panel by 20% and could be done in a day.

Dan, I like your channel and I think you stuff is great, but after some time... have you deliberated on this? It's such a simple concept that one pretty much assumes that you if you concentrate the lumens, you also concentrate the heat. Sure it'll put out more power, but if a cell is designed to be in open sun, then it's been maximized and it only makes sense it wasn't designed to handle more heat than it was designed for. At a 10% increase in power... at 17% efficiency - BIG Heat additon
