question can i put a house solar panel on my ute i just had 24 panels fitted to my house and there was one spare so i want to put it on my ute when we do the big lap next year .i was told by a mate that the house panel may put out to much power and fry my batteries .
panel specs are :model type :gcl-p6/60265
265w (0~+5w)
vmp31.0v
imp8.55a
voc38.1v
isc 9.20a
max rectified current 10 a
fuse 15a
any imfo please cheers griffo

Yep as long as voltage reg is within voltage range of panel . Panel mounted correctly .

I thought house panels were 24v.
Hence the 31\38.1 v on label?.
1 if you want to get the full benefit out of its 265Watts then you will need to use a quality MPPT regulator. If you use a simple regulator or a cheap fake MPPT regulator you will only get half the power and will probably think the panel is crap. Yes really you will only get about 120 Watts maximum. Ask about a proper MPPT regulator if you need more information but you will need a 20Amp model minimum, not the 10 Amp one, on that link from Aus Kiwi.
2 That is a very big panel for mobile use and will be in real danger of cracking the glass. The middle of the back side should be also supported to help prevent the glass from cracking IMHO. If you put some soft support underneath as well as the side supports it should be OK most likely.
Of course you must use a regulator of some sort with any panel to regulate the charging of the battery or you will fry all your batteries.

The one in link is not recommended for this particular unit . If you asked and saw the whole series it mentions this . Sheesh !it lists up to 40 amp .

Hi Aus-Kiwi
The second reg there is OK, the 2210A model with 20A charge rating. It just scrapes in above the wattage by 2% but if the panel is flat mounted that will not be a problem. and they limit anyway. The max voltage allowed is high at 92-100V which is more important for longevity. Note that panel is only good for a 12V battery. It will disappoint charging a 24V battery under some conditions.
The Tracer MPPT units work OK in my experience. Probably the best price units which do work properly as MPPT. They can also be bought from other suppliers including ebay at good prices.

i have a 15amp solar controller do you think that would work ? it reads 12v/24v 15amp

Hi
Do you want to know if it will work ? or if it will work properly and get the full output of the panel ?
If the solar controller/regulator is a normal PWM type it will work BUT you will get only ~ 9 Amps so at ~14V that is only 126 Watts maximum. Is that what you want.
If it is MPPT then the 15A rating will not be enough for charging a 12V battery from that panel. As I said it will need to be rated at 20A. If the controller does not self regulate on current, then it will probably burn out sooner rather than later!! This will put the battery at risk !

Hi griffo
I would say two things about that panel.
1 if you want to get the full benefit out of its 265Watts then you will need to use a quality MPPT regulator. If you use a simple regulator or a cheap fake MPPT regulator you will only get half the power and will probably think the panel is crap. Yes really you will only get about 120 Watts maximum.
