Refund & Warranty Policy

01Overview

This policy explains the warranties that come with a Rainbow Solar rooftop system and our rules for cancellations and refunds. It forms part of our Terms & Conditions. The exact brands, models and warranty periods for your system are listed in your quotation and on the warranty card we hand over at commissioning. If they differ from this page, your quotation and warranty card apply.

02Solar panel warranty

We install only Tier-1, ALMM-listed panels from approved manufacturers. Each panel carries two manufacturer warranties:

25-year performance warranty

The manufacturer guarantees that your panels will keep producing a minimum share of their rated power for 25 years, with up to 30 years on select premium TOPCon and bifacial panels. A typical linear guarantee looks like this:

*Exact figures depend on the panel brand and model and are stated on the manufacturer's warranty certificate.

If a panel produces less than the guaranteed output, the manufacturer will repair it, replace it, or supply additional panels to make up the shortfall, as per its warranty terms. Rainbow Solar will test the panel, raise the claim and handle the replacement for you.

10–12 year product warranty

Covers defects in materials and manufacturing, such as delamination, junction-box failure, frame defects or cell cracks not caused by external damage.

03Inverter warranty

Inverters carry a manufacturer warranty of 5 to 10 years, depending on the brand and model in your quotation. Some brands offer optional extended warranties, which we can arrange at extra cost. During the warranty, a faulty inverter is repaired or replaced by the manufacturer. We coordinate the service visit and, where possible, help keep your downtime short.

04Battery warranty

For hybrid and off-grid systems, batteries are covered by the battery manufacturer's warranty, typically 5 years for lithium batteries and 2–3 years for lead-acid batteries. Battery warranties may also be limited by the number of charge cycles or the energy delivered, as stated by the manufacturer.

05Workmanship & structure warranty

Rainbow Solar gives its own 5-year workmanship warranty from the date of commissioning. It covers:

• the mounting structure we supplied and installed, including rusting of galvanised parts under normal conditions;
• DC and AC cabling, connectors, junction boxes and earthing done by us;
• roof penetrations and fixings made by our team;
• any fault caused by the way we installed the system.

Under this warranty we will repair or redo the faulty work free of charge, including parts and labour.

06What is not covered

• Damage from natural disasters, lightning, flood, cyclone, fire, earthquake or other events beyond our control.
• Theft, vandalism, accidents, animals or birds, or falling objects.
• Grid voltage fluctuations, faulty building wiring or earthing that we did not install.
• Repairs, modifications or relocation by anyone other than Rainbow Solar or its authorised technicians.
• Roof leaks, cracks or structural defects in the building, and civil work not part of our installation.
• Lower generation due to dust, bird droppings, new shading or lack of cleaning.
• Normal wear and tear and cosmetic changes that don't affect performance.
• Wi-Fi, internet or mobile-app issues affecting remote monitoring.

08Cancellation policy

You can cancel your order by writing to us by email or WhatsApp. The amount refunded depends on how far your order has progressed:

We may also cancel an order and refund the amount paid (less costs already incurred) if your site turns out to be unsafe or unsuitable, or if required approvals are refused for reasons outside your control.

09Refunds

• Approved refunds are processed within 15 working days of the cancellation being confirmed.
• Refunds are paid to the same bank account or payment method used for the payment. We never refund in cash.
• If you paid through a solar loan or EMI, the refund is made according to the lender's process, and any lender fees are governed by your loan agreement.
• You will receive a written confirmation showing the amount paid, any deductions and the final refund.

10Non-refundable charges

• DISCOM application, registration, meter and inspection fees already paid to the electricity board.
• Government portal or documentation charges already incurred.
• Custom-fabricated mounting structures made specifically for your roof.
• Site survey charges, where a paid survey was agreed (standard surveys are free).

11Subsidy & refunds

The PM Surya Ghar subsidy is paid by the government directly to your bank account and is not part of our invoice. A delay, reduction or rejection of the subsidy is not a reason for a refund once your system is installed, but we will help you follow up with the authorities. If you cancel before installation, any subsidy application filed for you will be withdrawn.

12Transferring your warranty

If you sell your property, the remaining warranty passes to the new owner. Just inform us in writing with the new owner's details so we can update our records and the manufacturers' registrations.
