Solar Private PPA

A Solar Private PPA is a financial agreement that allows businesses to use electricity generated from solar cells without having to invest in a solar system.
The electricity generation system will be installed and maintained entirely by Siam First Co., Ltd. The business operator will purchase the generated electricity at a specified rate.
The price and duration are as agreed upon in the contract.

Advantages of Solar Private PPA

  • No upfront investment: Energy users bear no costs for the installation and maintenance of solar power systems; the energy producer takes all responsibility.
  • Electricity cost savings: The electricity rate paid by energy users under a Power Purchase Agreement (PPA) is lower than the price paid to the power grid, resulting in long-term electricity cost savings.
  • Reducing financial risk: Siam First Co., Ltd. assumes responsibility for the risks associated with the installation and maintenance of solar cell systems.
  • Promoting renewable energy: Helps increase the use of environmentally friendly energy and reduce greenhouse gas emissions.
