Nice work,
I'll ask this again here: I live in Ohio, USA and pay 6.5 cents per killowatt hour.
Whuch product should I buy & what is the break even period for the investment to have paid for itself?
Or is this my doing the right thing patch for the day by reducing dependence on fossil fuels somehow?
Not sure what that's worth to me, but feel free to say how much this costs me & I'll decide.
