Solar Controllers--Don't be a Sucker! :(
Just got to say it again, how it is we are sitting here for five months off grid on solar with no problems at all (third season on solar like this), using the non-programmable, non-MPPT, solar control...

I've sort of done a less expensive version of that for just my one panel type. I saw an honest +/- 10% full sun gain for an ideal MPPT controller vs direct to battery (PWM style). Not 30% but not 0 either. That's my working number until I collect more data under more conditions.
