Solar Panel Subsidy in Kerala 2026

The central government provides financial assistance to eligible households installing grid-connected rooftop solar under the PM Surya Ghar Muft Bijli Yojana.

The scheme aims to make rooftop solar more accessible to residential electricity consumers and reduce their dependence on grid electricity.

How Much Solar Subsidy Is Available in Kerala?

The standard central subsidy structure for eligible residential consumers in Kerala is as follows:

System Capacity Central Subsidy
1kW ₹30,000
2kW ₹60,000
3kW ₹78,000
5kW Up to ₹78,000
10kW Up to ₹78,000, if eligible

The subsidy is capped at the applicable maximum. Increasing the system capacity beyond 3kW does not automatically increase the central residential subsidy.

Does the Kerala Government Provide an Additional Solar Subsidy?

The sources reviewed for this guide do not establish a separate, generally available Kerala state subsidy that can automatically be added to the central residential benefit. Kerala's rooftop solar programme is associated with the central PM Surya Ghar scheme, with implementation support through the relevant state agencies.

Before budgeting for an additional benefit, check the latest information from:

How to Apply for Solar Subsidy in Kerala

Eligible residential consumers should follow the current official application process.

  1. Register on the PM Surya Ghar National Portal.
  2. Enter the required electricity connection details and follow the portal's instructions.
  3. Select an eligible registered vendor according to the scheme requirements.
  4. Complete the installation and required inspection or commissioning steps.
  5. Submit the necessary details through the portal.
  6. Follow the official process for subsidy disbursement to the eligible beneficiary's bank account.

Confirm the current documentation, technical requirements and vendor eligibility before purchasing equipment. Buying a system independently does not automatically guarantee subsidy approval.

KSEB Net Metering for Rooftop Solar in Kerala

Net metering is an important consideration when planning a grid-connected rooftop solar installation in Kerala.

During sunny hours, your solar panels generate electricity that can be used by household appliances. If generation exceeds immediate consumption, surplus electricity may be exported to the grid under the applicable metering arrangement.

When solar generation is insufficient, your home can draw electricity from the grid.

Before installation, check the current KSEB requirements for grid connectivity, metering, system capacity, approvals and any applicable charges.

Why Is Net Metering Important?

Net metering can help households make use of surplus solar generation, subject to the approved arrangement and applicable regulations. However, exported electricity and electricity purchased from the grid may be treated differently under the relevant billing rules.

Your actual savings depend on your electricity tariff, consumption pattern, solar output and applicable settlement mechanism. Do not assume that every unit exported will necessarily offset a unit imported at the same financial value.

What Affects Solar Panel Installation Cost in Kerala?

Two installations with the same capacity can have different prices because the equipment and site conditions may vary.

1. Solar Panel Technology

Mono PERC and N-Type TOPCon modules have different specifications, efficiency characteristics and available wattages. High-wattage panels may reduce the number of modules needed for a given DC capacity.

2. Inverter Selection

The inverter converts the DC electricity generated by solar panels into AC electricity for household use. Its capacity, features and compatibility with the solar array affect the system cost.

3. Roof Type and Mounting Structure

Kerala homes may have flat concrete roofs, sloping roofs or tiled roofs. The mounting arrangement, roof accessibility, structural requirements and installation complexity can influence the final price.

4. Monsoon and Weather Conditions

Kerala experiences substantial seasonal rainfall and cloudy weather. Panels and mounting structures should be installed with suitable design, drainage and secure fastening for local conditions.

Weather conditions also affect solar generation, so annual output estimates are more useful than assuming that every day will produce the same number of units.

5. Electrical Protection and Installation

A complete system may include DC and AC cables, connectors, earthing, protective devices, installation labour, commissioning and applicable grid-connection support.

Ask the installer for a written quotation that clearly identifies the included components and any additional charges.

On-Grid vs Off-Grid vs Hybrid Solar Systems

The system type affects both the initial cost and how your property uses solar electricity.

Feature On-Grid Off-Grid Hybrid
Utility grid connection Yes No Usually yes
Battery storage Usually not included Generally required Available
Backup during grid outages Not with a standard grid-tied inverter Yes Yes, for supported loads
Initial cost Generally lower Depends on battery capacity Generally higher
Best suited for Reducing electricity bills Locations without reliable grid supply Solar savings with backup

On-Grid Solar System

An on-grid system is connected to the utility grid and is generally suitable for households looking to reduce electricity purchases. A standard grid-tied inverter usually shuts down during a grid outage for safety.

Off-Grid Solar System

An off-grid system operates independently of the electricity grid and normally uses batteries. It may be suitable for properties where grid availability is limited, but battery capacity and backup requirements influence the price.

Hybrid Solar System

A hybrid system combines solar generation with grid connectivity and battery storage, depending on the configuration. It can provide backup for supported loads, but it usually involves a higher initial investment.

Subsidy eligibility depends on the applicable scheme and approved system configuration. Confirm the requirements before choosing a battery-based installation.

How Much Electricity Can Solar Panels Generate in Kerala?

Solar generation depends on sunlight, roof orientation, shading, module efficiency and seasonal weather.

Solar System Capacity Indicative Daily Generation
1kW 3–5 units
2kW 6–10 units
3kW 10–15 units
5kW 18–25 units
10kW 35–45 units

These figures are indicative planning ranges, not guaranteed output. Cloud cover and monsoon rainfall may reduce generation on particular days.

A professional assessment can estimate expected annual generation based on your location, roof orientation, shading and equipment selection.

How to Choose the Right Solar System for Your Kerala Home

Selecting the right capacity requires more than comparing installation prices.

  • Review electricity bills: Check your monthly consumption over several billing cycles.
  • Assess daytime usage: Appliances used during daylight can consume solar generation directly.
  • Check rooftop space: Allow sufficient area for modules, mounting structures, maintenance and safe access.
  • Consider roof design: Sloping and tiled roofs may require different mounting solutions from flat concrete roofs.
  • Plan for backup: If you need power during outages, compare the cost of a compatible battery-based system.
  • Verify subsidy eligibility: Confirm the approved process and registered vendor requirements before installation.

The right system is one that fits your actual electricity requirements, roof conditions and budget.
