My views about solar PV grid connection issues

Hello all,

I have been quoted on Solar Novus Today, a US solar magazine.

"Technical issues to be addressed
The main technical issues to be addressed for off-grid systems will be correct sizing by the installer and proper installation by the local work force in off-grid areas. Also, there needs to be proper standardization for indigenous equipment such as the battery and inverters used in systems.

“Smart metering for solar system integration with grid will take a lot of time to be accepted since people see solar power as a solution for frequent power cuts in India” says Giridaran Srinivasan, Project Engineer, RESolve Energy Consultants. He adds that unstable grids across various states in India (where power failures are frequent) don’t accept decentralised renewable energy power and make net metering impossible during power cuts as grid tie inverters disconnect immediately when a grid failure occurs.

During power cuts, the owners can only use solar power by using off grid changeover switch or hybrid inverters (expensive hence used for large rooftops), although they are forced to consume all the power themselves, which is not always feasible, hence it is always good to have a battery backup for evening and night power requirements, which will also be helpful during blackouts and emergencies."
