Financing
Using a Bank Loan
With flexible terms and competitive rates, this finance option is designed to fit your budget.
Supported banks
We can help you get a loan from Bangkok Bank, GSB Bank or Kasikorn Bank. The loan interest rate is around 6.5%.
Monthly rates
We always recommend to set your loan rate to the same amount as your monthly solar savings so that your total monthly expenses stay the same.

You can choose how many years payback time you want for your loan and is usually 4-8 years. After that period you benefit 100% from the solar electricity.

Leasing the installation
Leasing is a great alternative to a bank loan.
Condition details
Leasing requires a down payment of 10% of the installation cost. Contract length is 2-6 years and interest rate 7-9%.
Ownership
During the leasing period you don't own the solar system and you don't need to do any cleaning, repairs or maintenance.
You can buyout the system any time or after the contract ends you will receive ownership of the system.

Financing summary
We offer three financing models that you can choose from:
Power Purchase Agreement (PPA): No upfront investment. You pay only for the electricity generated, at a lower rate than the grid.
Bank Loan: You own the system from day one, benefit from all incentives, and repay through scheduled installments.
Leasing: Fixed monthly payments for system use, with optional ownership transfer at the end of the term.
Each option includes full system design, installation, and support. Our team can help assess which model best aligns with your cash flow goals.
