Solar Module

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.

TOPCon (Tunnel Oxide Passivated Contact) solar modules are considered more efficient than existing technologies like mono-PERC and polycrystalline modules. In India, the industry is gradually shifting towards TOPCon due to its higher demand and superior efficiency. While mono-PERC modules typically achieve efficiencies of around 20-22%, TOPCon modules can reach 23-25% efficiency. This means they can convert more sunlight into electricity, making them a more effective choice for solar projects.
