GRID – CONNECTED / ON – GRID / GRID TIED SOLAR SOLUTIONS
- Mostly used in utility scale projects to supply electricity to the grid/DISCOM at pre-determined tariffs.
- Most suitable for areas where there are no or less power cuts and the customer pays high electricity tariffs.
- Can also be used for captive consumption. Depending on state solar policy, excess generated electricity can be given back to the grid and the customer can be eligible for Net – Metering or FiT (Feed-in-Tariff).
- Can be easily synchronized with Diesel gensets to reduce the overall cost of electricity/unit.
- Allows system to avoid storage (batteries), which has a huge cost.
- Can help people save huge costs and generate some extra income.
POSSIBLE SOLAR SOLUTIONS
Used for captive consumption. Viable to customers who are already paying very high electricity tariffs. Considering the rise in electricity tariffs due to various factors, combination of solar and grid can help save a lot of electricity cost. Excess energy generated can be given back to the grid and based on the policies, either net metering or pre-determined FiT (Feed – in – Tariff) is applicable. It can help people generate some extra income.
Used for captive consumption and efficient power backup system. Many people install high capacity diesel gensets for un-interrupted power supply. As the cost of diesel is high and the electricity tariffs are also increasing, the cost of generation of electricity becomes very expensive. Solar power can help reduce cost to a great extent in such scenarios, and result in huge savings.
STANDALONE / OFF – GRID SOLAR SOLUTIONS
- A battery bank is set up which stores excess energy and can be used later when required.
- Such systems have an application in areas which do not have access to grid at all or have very limited access to grid.
- They also have an application in areas which can’t afford power loss at all (Like: Hospitals, IT companies, Telecom towers etc.)
- Cost saving is not an advantage in such system because batteries have regular maintenance and recurring costs.
POSSIBLE SOLAR SOLUTIONS
- Standalone systems have many applications and can be used in various ways.
- Such systems are used where there is no access to the grid or any other source of electricity at all.
- These systems can be used with:
- Only DC Load
- Only AC Load
- Both AC & DC Load
- Suitable for areas which get very few hours of electricity in a day
- COMMONLY USED & MOST ECONOMICAL SOLUTION IN THE MARKET
- Most of the households already have Home inverters and batteries installed as a source of power backup. Modules and charge controllers can be purchased and installed along with this existing setup. With the help of charge controller & panels, batteries can now be charged with solar as well.
- Saves up the cost of installation of complete Solar PV system.
- Combines multiple sources of power such as Grid, Diesel, Wind, Solar & Storage to form a very high efficiency system
- Such systems offer great opportunity to reduce energy costs and ensure continuity in event of grid absence.
