    I am using a Redarc 25A in-vehicle 3-stage 12v battery charger (bcdc1225) to charge the aux batteries from the starting battery/alternator (Redarc.com.au). The in-vehicle charger also features a MPPT solar regulator, allowing delivery of max amount of solar power from the solar panels to the...

    I thought that might be the case. I did find one Canadian 200w 18v solar panel, but do not have any idea how to buy one. https://cdn.shopify.com/s/files/1/0408/8521/files/195w_69e64115-daf6-4a55-bdff-fb50c5c5dd2c.pdf Found several from China, but hesitate to buy direct from China...

    Death Valley with the Tacoma - Thanksgiving weekend 2015

    I was at Panamint Springs Resort Wednesday night thru Saturdaay. The temps were in the 60's daylight and 50's dark. I understand that there was a cold front that moved thru there Tuesday with high winds and extreme cold. I was lucky enough to miss that. Were the warm springs crowded for...

    Top One Solar - Solar Panel 200 Watt 12V Solar Panel Monocrystalline I have only been able to find 1 single solar panel rated at 200W, optimum power voltage Vmp 18 volts ( used for a 12v battery charging system). It's from a company in Australia, low energy developments com.au...

    Any suggestions for a single solar panel, 12v system, 100+ watts

    Do you have any quantative data comparing different solar panel performance in marginal conditions. I suppose comparing the output wattage of two panels mounted side by side (identical solar conditions) charging identical batteries in the same SOC using the same solar controler would be of great...

    Any suggestions for a single solar panel, 12v system, 100+ watts

    No, I have not decided on a panel yet. Did complete the air-spring install on my FWC to help lift the roof with two new panels when I get them.

    So that would be about $339 + $50 about $389 per panel delivered to CA for the Carmanah CTI-160 panel (made in Canada).

    Didn't intend to cause you any grief. Just could not understand the difference in price comparing the Grape solar 160 watt panel to the Carmanah panel. Most likely the Grape solar is made in China. I do see that the Carmanah is made in Canada.

    The Go Power solar panel kit looks good for $489. But I already have a solar controller. Looked at other Amazon go power stuff and found Go Power!

    Any suggestions for a single solar panel, 12v system, 100+ watts

    OK, so the two solar panels weigh in at about 25# each, for a total of 50# added to the roof. Will be removing the old 80W panel and an aluminum roof rack from the back of the camper roof. But I figure the weight on the roof will still be greater when I'm done. So first I need to do the 'roof...

    Any suggestions for a single solar panel, 12v system, 100+ watts

    Yes, more watts.... The 150watt 39x39.5 panels won't quit fit between the ceiling vents on the FWC. But if I remove the rear roof rack which I have only used one time, I will have two spaces on the roof that will allow the more traditional sized 150-160 watt panels (2 of them). I think that 300...

    Any suggestions for a single solar panel, 12v system, 100+ watts

    Great idea for solar panels on top of a jeep TJ. But I will add them to the top of a FWC camper on a Ford F-250 pickup. I think I might just go with the heavier ones, more watts & might last longer for me.

    Found this 150W panel, Renogy 150W Monocrystalline, odd size 39.5" x 39". I might have room for two of these. Edit....nope gust an inch too wide to fit on the space available. But if I remove the roof rack, which I have only used one time, I can have two normally sized 150-160 watt panels.
