Re: unique solar application
Use direct solar gain to heat hot water instead of using PV.
Using Pv to convert to electricity, and then to convert that electricity to heat is very inefficient. PV converts ~ 15% of available power, while solar hot water converts ~75%.
Direct solar hot water is way cheaper and way more efficient.
PS For example, a simple homemade solar hot water collector, made from scrap parts, and not very efficient (the last one I made) cost ~ $500 including the pump and controller, and produces ~ 75 gallons of 100F rise water on a good day.
Please note, being a moderator does not add any weight to my opinions 300 watts Siemens/BP panels,plus a Sun 90,, making ~400. ~30 amps into Rogue MPT-3024, 450 ah of Trojan T-105, Morningstar ts300 inverter, a Tri-Metric meter.a collection of antique generators, plus 2 Honda eu-1000i's (also a BS2512 IX controller) and assorted other stuff!
