If you plan to go solar, you have two financing options- make the upfront investment or let a third party invest in the system.
These are the CAPEX and OPEX solar models, each having its pros and cons. But one thing remains common- whether you own your system or not, switching to solar will help you slash your monthly energy expenses by at least 70-80%!
But how do you decide which type of system is right for you? Let’s take a deep dive into CAPEX and OPEX models to understand.
CAPEX Solar Model
In the CAPEX or Capital Expenditure model, the consumer pays for the equipment, installation, operation, and maintenance of the solar energy system. In short, the consumer bears the capital expenditure of the solar installation.
While cost-intensive, the CAPEX model gives the consumer complete rights to their solar asset. This right comes with tax and depreciation benefits along with the ability to send the excess energy back into the grid and be compensated for it.
Consumers also have the option of availing a solar loan, which slashes the financial burden of investing in solar without compromising on the benefits.
The CAPEX model is for those who have the required capital to make the full investment in solar. With energy savings, consumers can recover this initial investment within 5-6 years.
Advantages of CAPEX
- Complete ownership of the system, thus access to tax benefits, government subsidies, and rebates
- Faster return on investment
- Full protection against rising electricity tariffs for at least 25 years.
- High initial investment
- Since the consumer has complete rights to the plant, they also have to bear the risks and uncertainties involved
Cut Down Your Energy Cost by Almost 80%
OPEX Solar Model
OPEX or Open Expenditure shifts the responsibility of the solar plant to a third party and makes up for the drawbacks of CAPEX installation.
A consumer who wants to switch to clean energy but doesn’t have the capital ready to make the transition can ask a Renewable Energy Service Company (RESCO) to set up a solar plant.
The consumer provides the space, and the developer invests in the equipment, installation, commissioning, and maintenance of the plant. This type of installation is also called a land lease model.
What does the consumer get out of it? Cheaper and risk-free electricity!
The consumer enters into a Power Purchase Agreement (PPA) with the solar developer for a fixed tenure (between 15-25 years). During this period, the developer will provide them with energy at a negotiated tariff, which would be cheaper than grid power.
Once the PPA expires, the rights of the solar plant get transferred to the consumer at zero cost.
Advantages of OPEX
- The consumer only pays for the electricity
- The investment and performance risk is borne by a third-party
- The developer takes care of the Operations and management of the plant.
- The developer avails the tax benefits and rebates
- Longer breakeven period
- The consumer has no control over the electricity tariff.

How to Choose the Right Model?
Consider the following factors before the big decision:
1. Your Budget and Financial Resources
Your biggest consideration when deciding between OPEX and CAPEX models should be financing. If you are prepared to make the capital investment for solar installation, then the CAPEX model is right for you. This investment can also be in the form of EMI payments or a solar loan.
But, if the aim is to decarbonize without investing money into solar, and you have the roof space to set up a solar plant, then the OPEX model is best.
2. Risk and responsibility appetite
Large-sized solar plants, installed by businesses, often pose a performance risk as solar generation can be affected by multiple factors such as location, panel orientation, weather conditions, product quality, etc.
Moreover, they also require regular maintenance. If you are prepared to shoulder this risk and responsibility then the CAPEX model is right for you. If not, then it’s better to let a third-party developer do the same.
3. Ownership Rights
Owning the rights to the solar asset comes with certain benefits. For example, commercial and industrial solar installations can avail up to 40% accelerated depreciation on their solar plant.
CAPEX installations allow you to avail such benefits while the OPEX model does not.
