Feed-In tariff is the rate at which the DISCOM buys back solar power from it's customers after the self consumption of solar power by the customer. BESCOM in it's current policy is paying back Rs.3.56 per for each solar unit the customer gives to the grid. You can read more on the solar rooftop [...]
For Solar Rooftop, approximately 100Sqft of shade free area is needed for 1kVA Solar modules
Yes, this back-up can run the household loads during a power-cut as usual. This system will work independently of the solar system.
Solar power generated during power outages can be stored in batteries. These systems are called hybrid systems as they have battery storage facility as well as grid connection.
Depending on the state level policy, there are two different options for going grid connected/on-grid/hybrid: Net metering: The metering system where the power generated is first consumed by the loads in the building. Only excess is exported to the grid. In net metering, the bill is calculated as a difference of total export & total import [...]
Loads are nothing but the energy consuming electrical appliances. Light, fan, refrigerator, motor are some of the examples.
The Solar On-Grid PV System is connected to the grid via the Solar inverter. In terms of physical connection, the solar inverter (or grid-tied inverter/On-grid inverter) is connected to the distribution board of a building just like how a bad (equipment) point is connected.
The grid is electricity connection that a building has. In general, grid refers to the ESCOM (Energy Supply COMpany)
A Solar PV (Photo Voltaic) system which is connected to the grid where the system can potentially send power back to the grid as well. These systems are also called grid-tied systems
