Solar power system
With about 300 clear sunny days in a year, The amount of solar energy produced in India is merely 0.4% compared to other energy resources. The Grid-interactive solar power as of June 2007 was merely 2.12 MW. Government-funded solar energy in India only accounted for approximately 6.4 megawatt-years of power as of 2005. However, as of October 2009, India is currently ranked number one along with the United States in terms of installed Solar Power generation capacity.

| Power system|
|A Solar inverter is a type of electrical inverter that is made to change the direct current (DC) electricity from a photovoltaic array into alternating current (AC) in order use with home appliances and possibly a utility grid(load).|
| Stand-alone inverters|
|Stand-alone inverters that are designed to be used without the presence of the electrical utility grid - can be run from PV panels and batteries using a charge controller. The charge controller regulates the input from the PV and the batteries, regulates the battery output, and handles charging the batteries.|
| Battery backup inverters|
|These are special inverters which are designed to draw energy from a battery, manage the battery charge via an onboard charger, and export excess energy to the utility grid. These inverters are capable of supplying AC energy to selected loads during a utility outage, and are required to have anti-islanding protection|
| Anti-islanding protection|
|Normally, grid-tied inverters will shut off if they do not detect the presence of the utility grid. If, however, there are load circuits in the electrical system that happen to resonate at the frequency of the utility grid, the inverter may be fooled into thinking that the grid is still active even after it had been shut down. This is called islanding.|
An inverter designed for grid-tie operation will have anti-islanding protection built in; it will inject small pulses that are slightly out of phase with the AC electrical system in order to cancel any stray resonances that may be present when the grid shuts down.
Solar inverters use special procedures to deal with the PV array, including maximum power point tracking and anti-islanding protection.
