Solar PPA Thailand: Solar Power With Zero Upfront Cost

Bustan Energy funds, builds and maintains the rooftop system. You simply buy cleaner power at a lower rate than the grid.

A solar PPA (Power Purchase Agreement) is the no-CAPEX route to solar for Thai factories, resorts and commercial buildings. We invest in the system on your roof and you pay only for the electricity it produces, at a rate below your current PEA or MEA tariff. No loan, no maintenance burden.

How a solar PPA works

Bustan Energy designs, finances and installs a rooftop solar system at no cost to you. Over a fixed contract term you buy the generated electricity at an agreed per-kWh rate, lower than the grid. We own and maintain the equipment for the full term; at the end the system can transfer to you. Your monthly bill drops from day one.

  • Zero upfront investment, no bank loan required
  • Per-kWh rate locked below your PEA/MEA tariff
  • Bustan owns O&M, insurance and monitoring
  • System ownership transfers to you at term end

Who a PPA suits best

PPAs are ideal for businesses with high daytime consumption and stable load: manufacturing plants in the EEC, Rayong and Chonburi, cold-storage facilities, resorts and hotels, and large commercial buildings. If you prefer to preserve capital for core operations and treat energy as a predictable operating expense, a PPA fits cleanly into your P&L.

  • Factories with steady daytime electricity demand
  • Resorts, hotels and cold-storage operators
  • Companies that want to protect cash and credit lines
  • Sites with usable, structurally sound roof area

PEA / MEA coordination handled for you

Grid-tied solar in Thailand requires approval from PEA or MEA, plus the right interconnection and metering setup. We manage the full permitting and utility coordination, install Tier-1 panels and inverters, and commission the system to standard. You keep running your business while we handle the paperwork and engineering.

  • Full PEA/MEA application and interconnection
  • Tier-1 panels and inverters, professionally installed
  • Compliant metering and grid-tie commissioning
  • Single point of contact from survey to switch-on

Savings, ESG and reliability

A PPA cuts your energy cost immediately and shields you from rising grid tariffs over the contract. It also lowers your carbon footprint, supporting export, supply-chain and ESG requirements that many Thai manufacturers now face. Live monitoring means underperformance is caught fast, so you keep getting the output you pay for.

  • Immediate reduction in electricity spend
  • Protection against future tariff increases
  • Lower carbon footprint for ESG and export needs
  • 24/7 performance monitoring by Bustan

Frequently asked questions

Does a solar PPA really cost nothing upfront?

Yes. Bustan Energy funds the entire system, including panels, inverters, installation and PEA/MEA approval. You pay only for the electricity produced, at a rate lower than your current grid tariff.

How long is a typical PPA contract in Thailand?

PPA terms commonly run for several years to align with the system payback. The exact length depends on your consumption and roof size. We tailor the term and rate after reviewing your electricity bills.

Who maintains the solar system?

Bustan Energy owns and maintains the system for the full PPA term, including O&M, monitoring, insurance and repairs. You carry no maintenance cost or technical responsibility.

What happens when the PPA ends?

At the end of the term the system can transfer to you, often at no or low cost, so you then enjoy near-free solar power for the remaining life of the equipment.

How do I find out if my site qualifies?
