I'm looking into stepping up my solar game
. My boat
came equipped with 3 solar panels
totaling 370 watts that were installed in 2008. Realistically I get about 26 amps in full sun, if I push the mizzen boom so it does not shade them. They are currently running through 2 solar
boost 2512i (the lower voltage version) charge controllers.
I can get about 5 days before I have to crank up the generator
and recharge the batteries
. My goal in upgrading is two fold - one is to hopefully eliminate this need, and the other is to run my DC watermaker
off of them (pulls about 25 amps running).
I'm looking into two possible setups, one is the Hightec 200+25% solar panels
, which are rated at 200 but claim to get up to 225 watts if they can get reflected light on the back side because they are bi-facial. 3 of these would produce 600-675 (50-56 amps). The only additional equipment
I would need for this set up is another 2512 charge controller.
Another option is 2 Panasonic 335 watt panels
, for a total of 670 (56 amps). For this I would need to upgrade to 2 3024 charge controllers. This is the more expensive option by about $400 and dimensionally these are a few inches longer and wider than my current
I'm leaning toward the 3 panel setup. It seems like it would be less affected if the mizzen boom is centered, but also I can re-use some of my existing hardware
. I'm not familiar with Hightec brand, but they were the highest wattage mono panel I could find that would fit in the same footprint that I have now.
