Benefits of Solar Installation in Kerala

Kerala, known as "God's Own Country", is not just blessed with lush greenery and backwaters, but also an abundant supply of sunshine. With over 300 sunny days a year, the state has enormous potential to tap into solar energy — a clean, renewable source that can significantly reduce both electricity bills and carbon footprints.

Why Solar in Kerala?

Kerala’s energy demand has been on a consistent rise, especially with growing urbanization and technological advancements. Despite its natural resources, the state depends heavily on electricity from other states, making it vulnerable to supply disruptions and price fluctuations. Solar energy offers a sustainable solution to this problem, especially for households and businesses.

Key Benefits:

• Abundant Sunlight: Kerala receives an average of 4–6 kWh/m² of solar radiation per day, making it ideal for photovoltaic (PV) installations.

• Reduction in Electricity Bills: A well-planned solar power system can reduce your monthly electricity bills by 70–100%.

• Government Subsidies: The Kerala State Electricity Board (KSEB) and the Ministry of New and Renewable Energy (MNRE) offer subsidies and incentives for residential rooftop solar systems.

• Environmentally Friendly: Solar power reduces dependence on fossil fuels, lowers greenhouse gas emissions, and helps combat climate change.

Types of Solar Installations

1. Grid-Tied Solar Systems

   • Connected to the state’s electricity grid.

   • Ideal for homes and businesses that want to offset their electricity use.

   • Excess power is exported to the grid (net metering).

2. Off-Grid Solar Systems

   • Independent of the grid, powered by batteries.

   • Useful in remote or rural areas with unreliable electricity.

3. Hybrid Solar Systems

   • Combination of grid-tied and off-grid systems.

   • Provides flexibility and backup power during outages.

The Installation Process

Installing a solar system in Kerala involves a few steps:

1. Site Survey: Professionals assess the rooftop for orientation, shadow-free area, and structural integrity.

2. System Design: Based on energy needs and space availability, a customized system is designed.

3. Government Approval: Apply for subsidies and grid connection approvals through KSEB or approved agencies.

4. Installation: Solar panels, inverters, and other components are installed, usually completed within a few days.

5. Net Metering: A bi-directional meter is installed to track imported and exported electricity.

Cost and ROI

As of 2025, the average cost of a residential rooftop solar system in Kerala ranges from ₹50,000 to ₹75,000 per kW (after subsidy). A 3 kW system can meet the average household's needs and typically pays for itself in 4–6 years through savings on electricity bills.

Popular Solar Installers in Kerala

Future of Solar Energy in Kerala

Kerala’s solar potential remains largely untapped. The government aims to install 1000 MW of solar capacity under the Soura Project, promoting rooftop installations across households, schools, and public buildings.

As solar technology becomes more affordable and accessible, and awareness spreads, Kerala is well on its way to becoming a solar-powered state — lighting homes, saving costs, and preserving the environment for future generations.
