Why Invest in Solar Panels in Goa?
Goa’s abundant sunshine makes it an ideal location for solar energy adoption. Installing solar panels not only reduces electricity costs but also ensures a reliable power supply, especially during outages. To encourage solar adoption, the Goa Energy Development Agency (GEDA), in collaboration with the Department of New and Renewable Energy, offers attractive subsidy schemes for residential and commercial solar installations. These subsidies significantly lower installation costs, making solar energy more affordable for homeowners
Components of a Rooftop Solar System
1. Solar Panels
The heart of any solar system is its photovoltaic (PV) panels, which convert sunlight into electricity. Options include monocrystalline, polycrystalline, and bifacial solar panels, each offering different efficiency levels. Bifacial solar panels are increasingly popular for their ability to generate electricity from both sides.
2. Solar Inverter
Since solar panels produce direct current (DC) electricity, an inverter is essential to convert it into alternating current (AC) for household use. On-grid inverters (3kW to 10kW) allow seamless integration with the main electricity grid.
3. Solar Battery (Optional)
Batteries store excess solar energy for use during nighttime or cloudy days. This feature is ideal for areas with frequent power disruptions.
4. Mounting Structure
Solar panels must be securely mounted on rooftops or ground installations at the optimal angle for maximum sunlight exposure.
5. Net Meter
A net meter tracks surplus energy sent back to the grid, allowing homeowners to earn credits or even income from their solar investment.
Types of Rooftop Solar Systems
1. On-Grid Solar System
- Best for reducing electricity bills (up to 80% savings).
- Grid-tied system allows surplus energy to be exported to DISCOM for financial credits.
2. Off-Grid Solar System
- Ideal for remote areas with frequent power cuts.
- Uses batteries to store extra energy for uninterrupted supply.
3. Hybrid Solar System
- Combines on-grid and off-grid features.
- Generates electricity while storing excess energy for backup use.
According to solar industry experts, hybrid solar systems provide the best balance between cost savings and reliability.
Solar Subsidy Schemes in Goa
The Government of India and the State of Goa jointly provide financial assistance to make solar installation more affordable. Here’s a breakdown:
1. Central Government Subsidy (Direct Bank Transfer – DBT)
- 40% subsidy for 1kW to 3kW systems.
- 20% subsidy for 4kW to 10kW systems.
- The subsidy amount is transferred directly to the customer’s bank account within 30 days of system commissioning.
2. State Government Subsidy (Goa-Specific Incentives)
- Goa provides an additional 10% subsidy for systems up to 3kW.
- For 4kW to 10kW installations, the state covers an extra 30% subsidy.
