I’ve got a quote in my drawer for a complete solar system for my operation, including battery storage and installation, about 50KW continuous. With my power rate of 0.09 cents, the payback period is right at 5 years (I.e. 20% rate of return). The system is too big for net metering. If we could do net metering (no storage), the payback period is a little over 3 years.
All those numbers are pre-China tariffs.
I really don’t care what your six lite bulb system costs...it’s irrelevant compared to industrial scale generation.
