Our system has been working for about 2 1/2 years. Our meter records energy drawn from the grid and energy fed into the grid. Our contract with the utility has a connection fee of about $11/month and if we produce more than we use, they cut a check at the chosen anniversary date ( end of April).
Last spring our bill for the year (usage) was about $100. We use electric baseboard heat, electric water heater and range. The system cost us about $18, k and I figure our payback at around 10 years.
I have been very happy with it.
No batteries. We have a generator wired into the house in case of power interruption.
