how many panels can you hook together 25watt. i need 65 amps.

thanks o.

Things have changed since 2009 when this was last answered. A 5 amp @17V Ramsond solar panel (100 watts for charging 12V batteries) is only $259 now, and not much bigger than one of these. For $3000 you could have your 65 amps, or approx 1200 watts, which is one BIG battery charger. You are almost getting into a small "whole-house" system at that level.

They don't come in a 25 watt version, 15 watt being the highest available for a single unit. In order to get your 65 amps, you would need to hook up 65 of the SolarFlat units (each unit outputs 1000mA), but you’re likely going to see some funky output with that many linked together. Also, that's 303 square feet of solar power. You might want to consider an alternate solar/power source or contact Brunton directly to see if they have any suggestions.
