Hot Water by Solar Electric direct via MPPT ?

[Logan005]

that would be some expensive hot water. maybe you are thinking a diversion load when you have too much power. there are a lot more cost efficient ways to heat water with solar.

What's your goal?

Have you considered a heat pump water heater?

Greetings,

I've been reading these informative messages for a while and I have a question that I didn't come across here.

Is it feasible to place ~600-750W of panels feeding that power to a MPPT to the lower element on a well insulated residential hot water tank? Say 50 -80 gals. I'm in Philadelphia PA.

I saw a MPPT offered at http://techluck.com/index.php#buy but I'm not sure if this can really be so easy. Could I be looking at a scam?

Appreciate any advice. Regards, Mark
