Hi,
Start with a big battery. Add 150 watts of solar for every 100 amp-hours of battery bank, with a good controller. Cost is currently under $2 per watt for materials.
If I'm understanding the above correctly, since I have two HD24-DP Interstates that have approx. 73 Amp hours each, I'd need 219 watts of solar capacity to recharge them? I've seen others put up 300-500 watts of solar capacity so is this overkill or have I misconstrued your information? Maybe he's already done so, but seems to me the OP would want the same information on the Costco system before committing.
