Frequently Asked Questions

What is OPEX solar?
In the OPEX (Operating Expenditure) or PPA model, a third-party investor or developer sets up the solar plant on your roof at zero upfront investment. You only pay for the solar energy generated at a predetermined, lower tariff than the grid.
How does an OPEX model work?
The solar provider designs, funds, installs, and maintains the solar system on your site. You purchase the generated solar power every month for an agreed contract period (typically 10–25 years).
Who owns the solar system in OPEX?
The solar power developer/investor owns the asset during the agreement period. After the agreement expires, the system can either be transferred to you or decommissioned as agreed.
What do I pay in an OPEX model?
You only pay for the units (kWh) of solar electricity generated and consumed, usually at a discounted rate compared to your utility electricity tariff.
What happens after the contract period?
At the end of the contract term, ownership of the plant can be transferred to you at zero or nominal cost, allowing you to enjoy free solar electricity for the remaining lifespan of the panels.
