This is a little project I'm running to test the performance of three solar panel types under varying conditions. The review covers crystalline, amorphous and CIGS (Copper Indium Gallium (di)Selenide) PVs. I'm also testing a MPPT vs PWM solar charger.

This is for my own interest and is not very scientific but I'm trying to learn along the way...enjoy.

  • @mjlorton No worries, glad to be of service...  I'll try to PM y' a present, the Raw Data of the SunFoil Project. I suspect y'll enjoy it ?

    Ciao !

  • @WarblesOnALot I did! thanks very much.

  • @mjlorton G'day... VERY Nice..! However, I understand that the 19-21 Volts measured at the PV is "Open Circuit", & at Zero Amps. If y' put a Clampmeter on the Lead, while A Multimeter does the Volts, y'll see it. Then get a 2nd Multimeter, set to Amps & as the Amps at Short-Circuit rise, Volts will drop.... The Battery's Voltage (Resistance to Charge) rises, as it's Resting-Discharge is replaced. A 1.7 Amp rated PV gives 1.9-2.1 Amps, at Open Circuit.

  • @WarblesOnALot Thanks for the comment and feedback.

  • i so want to know more, could you please msg me with a name of a good book to buy for building a solar panel as i would like to start a little project of my own.

  • @786Mujy Hello, I'm sorry but I have not used any books as a reference. I know there are some books on Amazon but I think you'll find the best information on Google and YouTube.

    Cheers,

    Martin.

see all

  • @mjlorton Excellent !

     My Yt Channel began purely to publicise the SunFoil. To bolster the Credibility of my (Autodidactic) work, I decided to upload clips of other stuff I've been "Not Wrong" about..., and stuff that happens, here on the Endangered Species Sanctuary. So far, most people have been highly resistant to the idea that their Sacred Car can be improved... So, please tell all y'r friends !

    Ciao...

  • I've played around with solar for a while too, and I agree with everything you say :) I like to blend the usage of amorphous and polycrystalline, given their different attributes. Check out some of my (kind of crude) but interesting under one watt low level light circuits based (roughly) on Tesla's original concepts.

  • Nice build! That'd be great set up for a boat or a camper.

  • can u provide a diy link for mppt charge controller on at least more info on mppt thanks great
