Before any homeowner or business owner in India decides to go solar, one question comes first — how much is this actually going to cost me?
It is the most searched question in the entire solar category, and it is completely fair. Solar is a significant investment and you deserve a clear, honest answer — not a vague range designed to get you on a phone call.
The challenge is that solar panel prices in India vary considerably based on system size, panel brand, inverter type, roof structure, and location. What a neighbour paid two years ago may not reflect what you will pay today. And the growing number of solar companies quoting wildly different prices adds to the confusion.
In this complete price guide, Ascent Energy — Vadodara’s most trusted solar installation company with 12+ years of experience — breaks down the actual cost of solar panels in India for every common system size. We cover what is included in the price, what drives the cost up or down, how much government subsidy you can claim, and what your real monthly savings will look like after going solar.
By the end of this article, you will know exactly what to expect — and exactly what questions to ask any solar company before you sign on the dotted line.
Before we get into the numbers, it is important to understand what you are actually paying for when you invest in a solar system. A complete solar installation includes several components — not just the panels themselves.
Solar panels: The photovoltaic modules that convert sunlight into DC electricity. Panel cost depends on the brand, efficiency rating, and wattage per panel. Higher-efficiency panels cost more but generate more electricity from the same roof space.
Solar inverter: Converts the DC electricity produced by the panels into AC electricity that your home appliances can use. String inverters are standard for most residential systems. Microinverters and hybrid inverters cost more but offer specific advantages.
Mounting structure: The aluminium framework that holds the panels in place on your roof at the correct angle. Quality matters — a poor-quality structure can cause panels to shift or corrode over time, reducing performance and creating safety risks.
AC and DC wiring and protection systems: All the electrical cabling, junction boxes, DC isolators, AC circuit breakers, and earthing components that make the system safe and compliant with Indian electrical standards.
Monitoring system: A device or app that allows you to track your system’s real-time performance, energy generation, and savings from your smartphone.
Installation labour: The cost of certified engineers and technicians carrying out the physical installation on your roof.
DISCOM approvals and net metering: Application fees and the cost of handling all documentation for grid connectivity and net meter installation with your local electricity distribution company.
Subsidy application processing: Authorised vendors like Ascent Energy handle PM Surya Ghar subsidy filing on your behalf at no additional charge.
When you compare quotes from different solar companies, always confirm that all of the above components are included. A quote that looks cheaper may simply be excluding certain components — only to add them back as surprise charges later.
Here is a comprehensive, up-to-date price breakdown for the most common solar system sizes installed in Indian homes and businesses. All prices below are indicative before government subsidy deduction.
Who is it for: Small homes or apartments with a monthly electricity bill between ₹500 and ₹1,500. Suitable for homes consuming 90 to 120 units per month.

The prices above are indicative ranges. Your actual quote may differ based on the following variables:
Panel brand and efficiency: Solar panels are broadly categorised into Tier 1 (premium brands like Waaree, Adani Solar, Vikram Solar, Tata Power Solar) and budget alternatives. Tier 1 panels cost 10 to 20 percent more but offer better efficiency, stronger warranties, and more reliable long-term performance. For a 25-year investment, choosing a reputed panel brand is strongly advisable.
Inverter type: Standard string inverters are the most cost-effective option and work well for most Indian rooftops. Hybrid inverters — which support battery storage — cost ₹30,000 to ₹80,000 more than string inverters but give you the option of adding a battery bank for backup power. Microinverters cost more but offer performance advantages on roofs with partial shading.
Roof type and complexity: Standard RCC flat rooftops are the most straightforward and lowest-cost to install on. Sloped, tiled, or metal sheet roofs require specialised mounting structures that add to the overall cost. Roofs with complex shapes or significant shading from trees or buildings may also add complexity and cost.
Location and distance: Installation costs can vary between cities. In Vadodara, Ascent Energy’s pricing is highly competitive given our local presence, in-house engineering team, and strong supplier relationships.
Battery storage: If you opt for a hybrid system with battery backup, add ₹40,000 to ₹1,50,000 to your system cost depending on the battery capacity chosen. Battery storage is particularly valuable in areas with frequent load shedding.
In the rush to offer the lowest quote, some solar companies cut corners on component quality. Here is where quality genuinely matters for a 25-year investment:
Solar panels — never compromise: Low-quality panels degrade faster, produce less electricity than rated, and may fail entirely within 5 to 7 years. Always ask for the panel make and model, efficiency rating, and performance warranty before accepting a quote. Ascent Energy installs only MNRE-certified, Tier 1 solar panels with a 25-year linear performance warranty.
Mounting structure — do not ignore: Thin, low-grade aluminium structures corrode quickly in India’s climate — especially in coastal or high-humidity areas. A failed mounting structure is a safety hazard and an expensive fix. Ascent Energy uses hot-dip galvanised or anodised aluminium structures rated for 25+ years.
Inverter — brand and warranty matter: The inverter is the most technically complex component in your solar system and the one most likely to need attention over 25 years. Choose a recognised brand with a 5-year minimum warranty and accessible local service. Ascent Energy uses inverters from brands including Solis, GoodWe, Growatt, and Delta — all of which have strong India service networks.
The upfront cost of a solar system is the biggest barrier for many Indian households — even after the PM Surya Ghar subsidy. Fortunately, multiple financing options make it possible to go solar with very low or zero upfront payment:
PM Surya Ghar subsidised loans: Nationalised banks including SBI, Bank of Baroda, Punjab National Bank, and Canara Bank offer solar loans at preferential interest rates specifically for PM Surya Ghar beneficiaries. These loans require minimal documentation and have attractive repayment tenures.
Standard home improvement loans: Many banks and NBFCs offer personal or home improvement loans for solar installations at competitive rates.
Solar EMI through installers: Some solar companies, including Ascent Energy, offer EMI arrangements in partnership with financing partners. In many cases, the monthly EMI is lower than your current electricity bill — making the switch to solar cash-positive from the very first month.
Comparing solar quotes can be confusing if you do not know what to look for. Here is a quick checklist to ensure any solar quote you receive is complete and comparable:
Confirm the exact panel make, model, wattage, and efficiency rating.
Confirm the inverter make, model, and warranty period.
Confirm the mounting structure material and specification.
Ask whether DISCOM approval, net metering application, and subsidy filing are included in the quoted price.
Ask for the expected annual generation in units and the estimated monthly saving.
Ask for the payback period calculation based on your current electricity tariff.
Ask for the complete warranty terms — panels, inverter, structure, and workmanship.
Ascent Energy provides a fully itemised, transparent written proposal for every customer — covering all of the above with zero hidden charges.
Solar panel prices in India have never been more affordable — and with the PM Surya Ghar subsidy of up to ₹78,000 available to eligible homeowners, the financial case for going solar has never been stronger. A well-designed 3 kW system in Vadodara pays for itself in under four years and delivers 20+ years of nearly free electricity after that.
The key to a good solar investment is not finding the cheapest quote — it is finding the right combination of quality components, experienced installation, and honest after-sales support.
