Basic FAQ’s on Grid Connected system without batteries -On- grid System
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.
On-grid systems without batteries can be considered for the following purposes: To neutralize the electricity bill and generate free, clean energy for oneself. To hedge against the increase in prices of electricity tariff · To generate some income over a long period of time. Yes, the solar plant is an asset that generates revenue throughout [...]
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.
The reason behind this logic is that during a power cut, in case electricity personals are working on the grid lines, export of solar power can cause electric shock to the people working on it. So this is more of a safety issue that solar generation stops.
The solar generation is stopped when there is a power-cut from the grid. The solar inverters have the inbuilt property called anti-islanding which makes sure that the moment there is a power outage at the grid, it will stop the solar generation.
Depending on the state level policy prevailing in your state for roof-top solar, the requirements for putting up a solar power plant can vary. In general, these are the few basic requirements for applying for a roof-top solar system: You should be the owner of the building where you intend to put solar. · You [...]
Grid connection can eliminate the requirement of batteries in a solar roof-top system which can give a longer life for the system without replacement of its parts. Apart from this the following benefits are also there compared to an off-grid battery based system: Lower system cost as lower accessories are required. · The inverter efficiencies [...]
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 [...]
