Best solar companies in India with subsidy and approvals support

Why subsidy and approvals matter

The PM Surya Ghar Muft Yojana has made rooftop solar financially attractive for Indian homeowners. But the subsidy is not automatic. It requires registration on the national portal, submission of documents to your local discom, a technical feasibility check, and a post installation inspection before any money reaches your bank account.

Many first time buyers assume the solar company handles all of this. In practice, a large number of local vendors install the system and then hand the homeowner a folder of forms. The family is left navigating discom offices, portal uploads, and inspection scheduling alone.

This is where company selection becomes critical. The difference between a smooth experience and months of frustration often comes down to whether your solar provider treats approvals as their responsibility or yours.

Government solar subsidy explained

Under the PM Surya Ghar scheme, the central government provides a direct subsidy for residential rooftop solar systems. The structure is straightforward. Homeowners receive ₹30,000 per kW for the first 2 kW of capacity. The third kW attracts ₹18,000. The total subsidy is capped at ₹78,000 for systems of 3 kW and above.

To claim this subsidy, the installation must be done by an MNRE approved vendor. The homeowner must register on the PM Surya Ghar portal before installation. After the system is commissioned and inspected by the discom, the subsidy amount is credited directly to the homeowner's bank account.

The process sounds simple on paper. In reality, each step has documentation requirements, processing timelines, and potential rejection points that can delay disbursement by weeks or months if not handled correctly.

What approvals are needed?

Residential rooftop solar in India requires several approvals before and after installation. Understanding these helps you evaluate whether a solar company is truly offering end to end support.

Criteria for choosing a solar company

When your goal is a low hassle residential solar experience with subsidy support, generic brand comparisons are less useful than a structured evaluation framework. We recommend scoring potential providers across these dimensions.

Detailed scoring matrix

Use this matrix to compare two or three shortlisted companies side by side. Score each criterion from 1 (poor) to 5 (excellent) based on what the company demonstrates during your initial consultation.

The heaviest weight goes to subsidy management because this is the step most likely to cause delays and frustration. A company that scores 5 on subsidy handling but 3 on aesthetics is a better choice for most first time buyers than one that scores the reverse.

How we approach approvals

We handle every step of the approvals process in house. When you book with us, our team registers your application on the PM Surya Ghar portal, files the net metering application with your discom, and coordinates the post installation inspection. You do not visit a discom office or upload documents to a government portal yourself.

Our technical site visit happens within 2 days of booking. Installation begins approximately 1 week after booking and takes 24 to 48 hours depending on system size. After commissioning, we track the subsidy disbursement status and follow up with the discom on your behalf.

We offer 12 month no cost EMI, which is fully interest free. This is designed so your monthly EMI can sit close to what you already pay in electricity bills, making the transition to solar feel less like a large purchase and more like redirecting an existing expense.

What good support looks like

A managed residential solar partner should feel invisible after installation. The system generates power, the net meter runs, the subsidy arrives, and maintenance happens on schedule. Here is what that looks like in practice.

Before installation, the company conducts a proper site survey. This includes roof inspection, shading analysis, electrical panel assessment, and a recommendation on system size based on your actual electricity consumption. The recommendation should follow the roof and your usage, not the company's margin preference.

During installation, the company manages all structural work, electrical connections, and inverter commissioning. They should test the system before leaving and walk you through the monitoring setup.

After installation, the company files all paperwork for net metering and subsidy. They schedule periodic panel cleaning and health checks. If the system underperforms, a generation guarantee means the company pays you back for the shortfall rather than asking you to troubleshoot.

Common subsidy mistakes to avoid

First time buyers often make errors that delay or reduce their subsidy. Understanding these helps you ask better questions during your solar company evaluation.

Registering on the PM Surya Ghar portal after installation instead of before is a common mistake. The portal requires pre installation registration for subsidy eligibility. Some families discover this only after their system is already commissioned.

Using a vendor not listed on the MNRE portal disqualifies the installation from subsidy. Always verify your chosen company's MNRE listing independently. Check the portal yourself rather than relying on the company's claim.

Mismatches between the approved system specifications and the actual installation trigger inspection failures. If the company installs a different inverter model or panel wattage than what was approved, the discom inspector can reject the commissioning report.

Incomplete documentation at any stage causes delays. Bank account details, electricity bills, identity documents, and roof ownership proof must all be accurate and current. A good solar company collects and verifies these before filing.

System sizes and typical costs

Understanding typical system sizes helps you evaluate whether a company's recommendation matches your actual needs. Here is a quick reference for common residential configurations.

A 3 kW system typically costs between ₹1.3 lakh and ₹1.6 lakh before subsidy. After the ₹78,000 subsidy, the effective cost drops significantly. This size suits a 2 BHK home with a fridge, washing machine, TV, and one AC.

A 5 kW system runs between ₹2.4 lakh and ₹3 lakh before subsidy. It fits a 2 to 3 BHK villa with two ACs and regular daytime usage. The subsidy remains capped at ₹78,000 for systems of 3 kW and above.

A 7 kW system is appropriate for larger villas with multiple ACs, a water pump, and potential EV charging. Systems in this range typically cost ₹4 lakh to ₹5 lakh (interpolating from the 8 kW range) before subsidy.

If a company recommends a system size without asking about your monthly electricity bill, appliance load, and roof area, that is a signal to look elsewhere. Proper sizing requires a site survey, not a phone call.

Financing and payback

Solar financing in India has matured considerably. Most homeowners now have access to EMI plans through banks and NBFCs. The key question is not whether financing is available, but whether the terms are transparent.

We offer 12 month no cost EMI, meaning zero interest for the full tenure. This is uncommon in the category, where most providers cap interest free periods at 6 months. Beyond the no cost window, standard bank EMI options are available at prevailing market rates.

Payback periods for residential solar in India typically range from 3 to 5 years depending on system size, local electricity tariffs, and actual generation. The subsidy accelerates payback meaningfully. A 5 kW system with full subsidy in a city with ₹8 per unit tariffs can pay for itself faster than the same system in a city with ₹5 per unit tariffs.

When comparing quotes, ask each company to show you a payback calculation that includes the subsidy, net metering credits, and any maintenance costs. A transparent provider will share this without hesitation.

Maintenance and long term value

Rooftop solar panels in Indian cities accumulate dust, bird droppings, and pollution residue. Without regular cleaning, generation can drop noticeably. Professional panel cleaning every few months is recommended, especially in dusty or industrial areas.

Beyond cleaning, periodic health checks catch issues early. Inverter faults, wiring degradation, and panel micro cracks can reduce output gradually without obvious symptoms. A company that includes scheduled health checks in its post installation plan is investing in your system's long term performance.

We include maintenance support as part of our residential solar offering. Our inverters are monitored every 5 minutes, which means faults are detected before you notice a drop in generation. Every panel is serial tracked, so if a specific panel underperforms, we can identify and address it without guesswork.

Why single point accountability matters

In a typical assembled solar system, the panel comes from one manufacturer, the inverter from another, and the mounting structure from a third. If something fails in year 5, the homeowner often has to figure out which manufacturer to contact, whether the warranty applies, and how to coordinate a repair across multiple parties.

We own every component warranty ourselves. Panels, inverters, and structures are all branded under our name. One call handles any issue, regardless of which component is involved. This is not just a convenience feature. It is a structural difference in how accountability works over a multi decade product life.

Our Arkashield guarantee provides a minimum generation promise. If the system underperforms the guaranteed output, we pay the homeowner back at ₹7 per unit of shortfall. This aligns our incentive with yours: we only succeed when your system generates what we promised.

Questions to ask any solar company

Before signing with any residential solar provider, ask these questions. The answers will tell you whether the company is a managed partner or just an equipment seller.

Do you handle PM Surya Ghar portal registration, or do I need to do it myself? Will you file the net metering application with my discom? Who coordinates the post installation inspection? What happens if the discom rejects the commissioning report?

What are your EMI terms, and is there a no cost EMI option? What is the total cost including installation, structure, and approvals? Is the subsidy amount already deducted from your quote, or is it separate?

Do you offer a written generation guarantee? What happens if the system produces less than promised? Who do I call if the inverter fails in year 7, you or the inverter manufacturer?

How often do you schedule maintenance visits? Is panel cleaning included? Do you monitor the system remotely?

A company that answers all of these clearly and confidently is likely a better long term partner than one that deflects or says “we'll figure it out after installation.”

Choosing a solar company for your home is a decision that plays out over decades, not days. The panels will outlast your car, your phone, and possibly your next home renovation. Prioritize the company that owns the full journey, from your first site visit through subsidy disbursement and every maintenance check after. We designed our process to be exactly that kind of partner, because we believe Indian families deserve solar that works without requiring them to become experts in government paperwork.
