For commercial and industrial buyers, the choice between a CAPEX (Capital Expenditure) model and an OPEX or RESCO (Renewable Energy Service Company) model is just as important as the choice of technology. Both paths deliver solar energy savings, but they differ significantly in terms of ownership, risk allocation, upfront investment, and long-term returns.
Under the CAPEX model, the business buys and owns the solar system outright. The full solar panel installation cost in India is paid upfront, either from internal funds or through a solar loan. Once the system is commissioned, all generated energy is free, and the buyer reaps the full financial benefit after the payback period, typically 3 to 5 years for commercial and industrial systems.
Under the OPEX or RESCO model, a solar developer such as GSE Renewables funds, installs, owns, and maintains the system at no upfront cost to the buyer. The buyer signs a Power Purchase Agreement (PPA) and pays only for the units of solar energy consumed, typically at a rate 20 to 40 percent below the prevailing grid tariff. This model is also called a zero-capex solar solution.
The comparison table below helps businesses evaluate which model is the right fit:
Parameter | CAPEX (Own and Operate) | OPEX / RESCO (Zero Capex) |
Upfront Investment | Full project cost paid upfront | Zero upfront cost |
Ownership | Buyer owns the system | Developer owns, buyer pays per unit |
Savings | Higher long-term savings after payback | Immediate savings from day one |
Maintenance | Buyer responsible (or via O&M contract) | Developer responsible |
Subsidy Benefit | Buyer can claim applicable subsidies | Developer claims; savings shared |
Best Suited For | Businesses with capital and long-term planning | Businesses wanting instant savings with no investment |
Contract Term | No long-term lock-in after ownership | Typically 15 to 25 years PPA |
ROI Payback | 3 to 5 years for C&I systems | Savings from month one; no payback period concept |
GSE Renewables supports both CAPEX and OPEX models across our commercial rooftop solar and industrial rooftop solar service offerings. Our team can help you model both options against your current electricity costs and identify the structure that delivers the best financial outcome for your business.
