If you are a resident of UP, your bill will show total surplus solar energy exported to the grid, total power taken from the grid and balance surplus solar power from previous month (if any). In UP, the calculations of net energy charges are done based on the solar power an grid power usage. However, even if your surplus solar power is more than your consumed grid power and the energy charges are in negative, you have to pay for your fixd monthy electricity meter charges and electricity duty.

Several solar companies provide Operations & Maintenance (O&M) service for the initial 5 years as the major components like solar panels and solar inverters provide warranty for this period. Some solar companies give regular monthly cleaning in a package during the time of installation either for a period of 5 years and even after that. There are also some companies dedicated to the O&M services at a cost. However, there are also several non-professional companies that have flourished. Some of them are seen using high pressure water and detergents to clean the solar panels. So please choose your O&M partner based on their team strength and background.
