Adopt solar power with no upfront investment. Pay only for clean energy consumed, while risks remain with the developer.
Understand how zero-CapEx solar works for your facility
Under the RESCO (Renewable Energy Service Company) or OPEX model, a solar power plant is installed at your facility by a third-party developer who owns and operates it. You do not invest any capital; you only pay for the electricity you consume at an agreed tariff (₹/kWh), typically lower than grid power.

How RESCO supports your sustainability goals
Adopting RESCO solar helps you integrate renewable energy, reduce carbon footprint, and meet ESG and net-zero commitments without capital lock-in. MISVA helps clarify carbon credit and green attribute ownership in your PPA so your reporting stays accurate and compliant.
Clear answers to common questions about RESCO / OPEX solar, contracts, ownership, and risk.
RESCO (Renewable Energy Service Company) or OPEX solar is a model where a third-party developer installs, owns, and operates a solar plant at your site. You pay only for the electricity you consume at an agreed tariff (₹/kWh)—no capital investment. The developer bears the capital cost, maintenance, and performance risk. It is ideal for industries and commercial users who want clean energy without blocking capital.
The RESCO developer owns and operates the plant, so they are responsible for all operations and maintenance (O&M). You only consume power; you have no performance or maintenance risk. Arrangements are governed by a Power Purchase Agreement (PPA). This includes cleaning, monitoring, repairs, and ensuring performance as per the PPA.
PPA terms are usually 15–25 years. MISVA helps you evaluate tenure, tariff escalation, and exit clauses so the contract aligns with your business plan and you are not locked into unfavourable terms.
Options typically include renewal at mutually agreed terms, purchase of the plant at residual value, or removal of assets by the developer. MISVA advises on exit and renewal terms upfront so you can plan ahead.
You need a long-term right to use the space—either ownership or a lease that covers the PPA period (typically 15–25 years). The developer will require secure tenure before investing. We can help assess your site and documentation.
In a well-structured PPA, performance risk sits with the developer. MISVA helps ensure performance guarantees and shortfall clauses are in place so your offtake and cost expectations are protected if generation falls short.
It depends on your consumption pattern and state policy. We assess whether behind-the-meter consumption, net metering, or a group captive structure suits you best and advise on the right arrangement for your location and load.
Ownership of carbon credits and green attributes (e.g. RECs) should be clearly defined in the PPA. MISVA advises on drafting and negotiation so your ESG reporting and sustainability claims are correct and legally sound.
