Solar Panel Mirror Booster 30% increase in power output with mirrors
Posted by admin in Search Engine Optimization Sunday, 3 October 2010 06:21 25 Comments
This video is a rough version of a concept using broken mirrors to boost the power output of a regular PV panel. Monocrystalline Solar. The Mirrors covered this panel equalling about a 2x factor total. This method done correctly can increase PV output by up to 50% but you risk overheating the cells. I suggest using one mirror maximum and do it for fun. If you need more power, get more panels. Doubling the sunlight adds 25% more power. It is not a 1 to 1 ratio. CPV chips are totally different. They are more expensive per watt than regular PV after price factoring the tracking device, dish construction, cooling unit. This panel was $199 with Free Shipping. SOLD OUT FOR NOW. My experience. Panels deliver the power they claim in a perfect world. Real world, expect 20% loss in conversion, heat, batteries, wiring. So 80 watts = about 64 watts with perfect sun and perfect wiring.

Hey, you guys make awesome videos, and I really like the work you do. The only thing I wonder with this concept, is if you cool the panel using water, as I’ve seen you do before, could you add more mirrors to the system without destroying the cells, or can the cells actually only handle a certain amount of power output?
If you were going to do this, I would do sun angle calculations. Face it towards the south, and have mirrors about 30% lager than the panel itself along the bottom. at such and angle where you get a full reflection right between noon and dusk. and about half the reflection at noon, to avoid burning out the panel, as well as getting a bigger boost during the time of day with less light.
I really like your video, but i wanna make a funny analyzation… I notice in your shadow that your moving your hands around alot behind the camera… haha thats funny… toward the end of the video.. your waving your hands around and no body sees… but your shadow gives ya away… just funny to me..

Very informative video. Got to learn a lot from it.
You would be much better off getting an inverter with higher efficiency. Broken glass mirrors are not only bad luck they scare me.
Great project.. Im working with a grid tie and solar too.. Its funny I was just going to do the very same this weekend and you already did the testing for me.
This was very helpful.. Keep up the great work.

I think galvanized mirrors or white rock will help also.
@cerrocoloradogtomx well, good luck with that bro. You’ll need about 150 of those and permanent daylight.
Dan manten el excelente trabjo hemos estado aprendiendo mucho de ti y tu esposa denise porsupuesto. Espero que no te moleste que hemos copiado algunos de tus videos y los hemos traducido en espanol para mostrarlos en pequenas comunidades en mexico que no tienen electricidad o formas para calentar sus casas. Gracias nuevamente y manten el excelente trabajo.
@paranoidnews Dude: You are pitiful. I’d rather plug my tv and playstation and desktop with 32 inch monitor, router, printer and all cell phone chargers to my solar system and with the money I save every month, buy a couple new games and movies. there is even a little extra money to pay for the phone bill.
@midairmark if you start using stuff like magnifying glasses with fresnel lenses problem is your going to generate alot of heat wich will likely fry your solar panels, like taking a magnifying glass to a solar panel.
Dan-
I really don’t understand what you are doing here. I have several kill-a-watt units and use them regularly. The measure the flow going thru (i.e. to measure how much power is being PULLED) – they are not meant to measure power generated- so i don’t at all understand how it has anything to do with your experiement with the mirrors. We recently had a 1.3 kw system plugged in and when the Kill-a-watt was plugged into the inverter, it would show 0 watts when nothing was plugged into it….
@SwindleFlu Hi,
Yes
Would Mylar film work also?
Dan,
I also have a 40 watt panel that I use for some outdoor lighting. I thought about using your mirror to to boost the panel but it seems to risky for broken glass. I am going to try a piece of polished aluminum instead.
I am looking for a low voltage timer to use with this 40 watt panel. I have it hooked up to a 100 ah marine battery and a photo sensor but don’t really need the lights on all night. Do you know of amy low voltage timers I could use with my system?

Dan,
Ive been watching your videos for a long time & love them. Thx for your efforts.
Ive a 3.8kw solar array on my house pointing SW & have a time of use meter with Los Angels DWP. Since the power peaks in the afternoon when DWP pays the most and we are away from home in the afternoons we end up sending power to the grid at peak time. This really seems to be working well as DWP pays high peal rates at that time.
Keep up the good videos.

Dude, that’s pitiful. I’d rather plug my TV & playstation into the electrical grid than spend that much time trying to milk miserable 60 watts of power out of each cell.
The solar panel design is inefficient, we need something better than the conventional solar panels.
My understanding has been solar cell efficiency drops as the temperature of the cell rises. Would be interesting to see how the panel performs with the mirrors towards the end of the period the sun shines on the panel for the day. Interesting experiment as it is, thanks for posting it Dan.
You boosted the power, but you also voided the warranty on your expensive solar arrays.
@midairmark Check the video response above.
Have you guys tried to boost power with the fresnel lens also? I thought magnifying might give more boost then just a mirror. Maybe yo can do a comparison, and then a combined boost %?
Great Video. So Mirror can increase PV Output. Have anyone try a prism so that only the related light (nm) hits the PV Panel. The other light can be use for other ie cooking & etc. Plus, lower the PV Panel temp.
