Look on it as 'regenerative braking for photons'
- It was all headed for the Martians anyways!
I can see the attraction of your own battery storage, because you are not then at the mercy of future POCO tariff differentials between your production and use suddenly making a mockery of your original investment calculations. Or at the mercy of power cuts. On the other hand, the grid ain't going to wear out like a set of storage cells and would be equal to a heck of a lot of $$$ worth of them. One thing bothers me. If you are generating at 240v, your power is not going to go economically more than a few miles, unless it backfeeds the transmission transformers to higher voltages. Is that possible?
