Solar PV

1. Solar Off-Grid Systems

Solar off-grid systems help eliminates the need for the grid. They are powered with the help of solar panels, batteries and back-up source such as generators (in case of rainy or foggy days). These systems are expensive because of the initial and recurrent costs of the batteries. Through proper system designing, costs of such systems can be significantly reduced.

These systems enable grid-independence in real sense.

2. Solar On-Grid Systems

Solar on-grid systems enable the connection with the grid which drives extra power back to the grid. These systems are favorable with continuous and reliable power supply from the grid. This helps the consumer to not only reduce but also eliminate his electricity bills by being environmental friendly and reducing overall carbon consumption.

Grid connected systems have the advantage of effective utilization of generated power as there are no storage losses. These systems are suitable for the industrial purposes where there is constant demand and generation, from grid and generator, of electric power. These systems can cut down on electricity bills for the industries, thus enabling them to be more cost effective.

3. Solar Hybrid Systems

Hybrid system is a combination of off-grid and on-grid solar systems where the batteries, solar panels and grid are monitored and decision is taken whether to charge/discharge the batteries or connect/disconnect to the grid.

Dependence on grid means that the cost of backup batteries is reduced and system dependence is shared between solar panels, batteries and grid, thus increasing reliability of the system. This also means that dependence on expensive diesel/petrol generators is also not required. These systems are more suitable for domestic and commercial concerns.
