Minimum Requirement for solar Rooftop plants :

A southern orientation is ideal although, East and west facing roofs can still capture over 80% of the energy.

Minimize roof obstructions to maximize PV capacity and aesthetics as shading can significantly reduce energy production.

  Plan for current and future landscaping, neighboring houses and roof “stick-ups”.

Approx. 100 sq. ft. of roof for every kW of PV capacity.

2.5 –5.0 kW for new homes depending size of home.

Need of grid connection for grid tied solar roof-top, net-metering is applicable where it is already enforced like Delhi, Gujarat, Andhra pradesh,kerala etc.

Grid tied System In grid tied systems, the system is interfaced with the state power

grid. Here, Solar takes the first priority to run the loads.

Second priority will be given to grid If the load exceeds the power generated by solar or cloudy environment, system automatically switched over to grid.

Third priority is given to DG sets which are much costlier than solar & grid power, Grid tied system can also be configured without a battery bank.

Off-Grid System Off Grid or stand-alone system refers to being independent of the

state grid. The design would support all the loads and sufficient back up would be provided to cater the power needs under worst conditions.

One can go off-grid for low intensity loads. In other words, all equipment having a power rating lesser than 500W can be taken off grid.

Hybrid and grid interactive System

Hybrid system is a smart system involving, solar, grid and diesel generator (DG). Here, Solar takes the first priority to run the loads. Excess power generated will charge the battery bank.

During night battery will support the loads till a safe battery voltage. System will

switch over to grid automatically below battery safe voltage. If GRID is not available and battery has been discharged, PCU can command DG to start and supply power to the loads till Grid or solar is restored.

Hybrid systems can also be configured as grid interactive systems where only solar and grid are present. Here, the first priority is given to solar. Excess power generated will charge the battery bank. During night battery will support the loads, till a safe battery voltage. System will switch over to grid automatically below battery safe voltage. This would extend the battery life and provide seamless power supply.
