Solar Panel Review / Comparison / Performance - Part 1/4

[WarblesOnALot]

@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...

@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 !

[mjlorton]

@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'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.

[KyleCarrington]

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

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.

[mjlorton]

@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.

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

Hey, why is your solar charger making a sad face?

[mjlorton]

LOL, good observation! At that point the solar panel input was switched to the MPPT charger so the PWM charger "was not happy".

[nomoreremakes]

@mjlorton Oh, I see. LOL :D

I like how you put this together. It's very attractive and neat, and I suppose, very handy as well, because you can grab it and go if needed.

[mjlorton]

Thanks for the comment. It is handy as a "research box" and in the case of a power failure...but with three 12 Ah batteries and all the other attachments it's a "little" too heavy to be a handy portable device.

I'm working on another solar charging project that will use Li-Ion batteries and will be very portable.

Hi, Do you have those watts up meters wired between the MPPT charge controllers output and your battery?

I want to get one for my solar set-up, as it gives more information and is cheaper than a MPPT controller with a built in LCD.

My system has no more than 100w input, so that should be ok for a 'watts up' style meter?

[mjlorton]

Yes, my Watts Up meters are wired between the solar panel and charger. They are also wired between the charger and battery. I use them for the very reason you state, they provide great information and are far cheaper than a display / logging on a controller.

The Watts Up meter can easily handel 100 watt and more so it'll work fine on your system.
