Introduction
With the growing adoption of rooftop solar in India, many customers find it difficult to choose between CAPEX, financing, and OPEX models. Although all three options provide the benefits of solar energy, they differ in terms of investment, ownership, and long-term returns.
Choosing the right solar model is crucial to maximize savings and efficiency. This guide explains each model clearly so you can make an informed decision based on your requirements.
What is the Solar CAPEX Model?
The Solar CAPEX (Capital Expenditure) model requires a one-time upfront investment to install the solar system.
Under this approach, the customer has complete ownership of the system. This leads to the lowest possible electricity costs over the long term.
In addition, residential users can benefit from government subsidies, further improving overall savings.
What is the Solar Financing Model?
The Solar Financing model enables customers to install solar systems without paying the entire cost upfront.
Instead of a large initial payment, the cost is divided into manageable monthly EMIs. This makes solar more accessible for homeowners and businesses.
Once the loan is repaid, full ownership of the system is transferred to the customer.
What is the Solar OPEX Model?
The OPEX (Operational Expenditure) model works differently from CAPEX and financing. In this case, a third-party investor installs and owns the solar system.
The customer only pays for the electricity generated, eliminating the need for any upfront investment.
However, since ownership remains with the provider, the overall long-term savings are usually lower compared to CAPEX.

Long-term savings are your top priority
Full ownership and control are important

EMI is lower than your current electricity bill
You prefer ownership with flexible payments
Choose OPEX if:
Zero investment is your priority
You don’t want to handle maintenance
You are a commercial or industrial user
Which Solar Model is Best in India?
There is no single answer that fits everyone. The right solar model depends on multiple factors such as budget, electricity usage, long-term goals, and risk tolerance.
The type of consumer—whether residential, commercial, or industrial—also plays a key role in the decision. Consulting an experienced solar provider can help you identify the most cost-effective solution.
