What is the RESCO / OPEX Solar Model?

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.

  • Solar power plant is installed at the client’s facility (rooftop or ground)
  • Entire investment is made by a third-party solar developer
  • Client purchases power at a lower tariff than grid electricity
  • Ownership, operations, and maintenance remain with the developer
  • MISVA acts as an independent advisor representing only the client’s interest
Zero CapEx Lower tariff No maintenance risk

Frequently Asked Questions

Clear answers to common questions about RESCO / OPEX solar, contracts, ownership, and risk.

What is RESCO / OPEX solar?

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.

Who maintains the solar plant?

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.

What is the typical contract duration?

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.

What happens after the PPA ends?

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.

Do I need to own the roof or land?

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.

What if generation is lower than expected?

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.

Is net metering required?

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.

Who owns the carbon credits?

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.
