Kerala, a southern Indian state, is pushing hard for renewable energy to lessen its need on fossil fuels. With the state’s high need for electricity and plenty of sunshine, solar energy systems present a cheap, sustainable, and clean alternative.

The Kerala solar subsidy program seeks to promote solar energy adoption among housing societies and homeowners. The program lowers the initial cost of solar panels and increases return on investment by offering financial assistance. For many clients, solar energy systems are now more reasonable and accessible thanks to subsidies.

It is crucial to comprehend the eligibility requirements, application processes, and advantages of the solar subsidy in Kerala in order to take use of it. Having access to reliable information enables customers to make well-informed choices on the installation of solar energy systems on

In Kerala, fixed financial assistance is offered by the central government of India through the Rooftop Solar Programme Phase – Ⅱ to encourage the installation of grid-connected rooftop solar systems in homes, large villas, and housing complexes. Kerala offers solar panels at substantially reduced costs when compared to unsubsidized models. Under the terms of net metering, these systems allow users to earn solar credits by selling excess electricity back to the grid.

In Kerala and throughout India, the National Portal for Rooftop Solar is essential to the processing and distribution of solar panel subsidies. This web-based platform provides customers looking to lower the cost of solar panels in Kerala with an easy-to-use and all-inclusive solution. A set subsidy amount is provided under the simplified program, which is dependent on the authorized solar system.


Here is an overview of the applicable subsidies for different rooftop solar system capacities:

Capacity (kWp)Applicable Subsidy of Solar Power Plant (Price Per kWp)
Up to 3 kWRs.14,588/kW
Above 3 kW and up to 10 kW₹14,588/kW for the first 3 kW, and ₹7,294/kW for the rest
Above 10 kWRs. 94,822

Resident Welfare Associations (RWA) and Group Housing Societies (GHS) can also benefit from a subsidy of ₹7,294/- per kW for common facilities up to 500 kWp.


In India, the average yearly electricity needs should be satisfied by the electricity your home solar system generates. In India, a 1 kWp solar power plant will typically produce 3–4 kWh of electricity per day, or 90–120 units of electricity each month. Examine your past year's worth of invoices to find the average monthly unit consumption of electricity you use. Then, divide that amount by 90 or 120 to get an approximate idea of the number of solar panels your home will require. You can also ask for guidance or, better yet, an estimate from us so that we can tell you roughly how much capacity will be needed. We're always willing to assist!

Because solar panels only generate electricity when exposed to sunshine, a net-metered solar plant for your home allows you to take advantage of the grid when your solar power generation isn't enough on any given day. Unused units are instead sold to the grid for solar credits on days when there is a surplus of solar production. The net metre monitors energy flow both ways and bills you the total amount each month.

Due to major obstructions like shading from a neighbor's property or an unfavorable roof orientation, some homes may not benefit from solar systems if their roofs don't receive enough sunshine. A solar installer can determine your roof's solar potential more precisely and can suggest that you sign up for a community solar farm, which offers solar benefits without requiring you to install panels on your roof.

Solar-powered homes often pay for themselves in 5-8 years. However, a lot of factors might affect your payback period, such as the cost of grid electricity in your area, the cost of your solar system, the method of payment (lease or loan), and the quantity of electricity you use. All things considered, most people benefit from solar energy because it produces a significant amount of energy at a reasonable cost and with continuous output for 25 years.

Many solar companies will provide a 25-year performance warranty for your home solar power installation. Even while the panels' energy output efficiency may start to decline after the first few years, they will still produce 85% of their initial production volume over the course of their 25-year lifespan. Following then, the output will begin to decrease, while some electricity will still be produced by the panels.

Most solar panel warranties are for 25 years. Large product warranties also include the other elements, such the inverter and batteries, however they are brand-specific. Additionally, your contractor will offer a workmanship warranty on the solar installation services.

For the solar system in your house to continue working properly, it must be regularly cleaned and maintained. However, major malfunctions in rooftop solar installations are unlikely because solar panels don't have any moving parts. Your solar provider may also provide an AMC package that covers your regular maintenance needs. This maintenance package includes comprehensive services like periodic inspections that aim to minimize downtime, improve system performance, and extend the life of your home solar plant.

With over 60 years of field testing and proven track record, polycrystalline solar modules are the most established and tested technology available. In terms of output from a unit area of light falling on it and conversion to electric energy, monocrystalline modules—a relatively recent technology—have a higher area-efficiency. On the other hand, monocrystalline modules will help you save some space (maybe a few square meters) in a 3 kWp power plant, regardless of whether you use polycrystalline or monocrystalline modules under STC (Standard Test Conditions) conditions. Recall that a 3 kWp solar panel, whether monocrystalline or polycrystalline, has undergone testing for 3 kWp at the factory prior to shipment; additionally, it will produce an identical power output and you are not paying for the technology—just the Wp output of the solar panels! Therefore, under all realistic circumstances, the only distinction between monocrystalline and polycrystalline solar panels is the ability of monocrystalline modules to reduce the area (maybe a few square meters) required to produce the same output; the output remains unchanged. In comparison to polycrystalline modules, monocrystalline modules are more costly. Therefore, it may be more economical to install more polycrystalline panels on your property to meet your energy needs if you have a large amount of space to work with or if roof area is not a major limitation. This is because polycrystalline panels are less expensive while producing an equivalent amount of power. Polycrystalline solar panels may offer a greater financial return and return on investment for you, depending on your location and available space. This technology is also developing swiftly in this field.
