Solar EPC Thailand: Engineer, Procure and Own Your System
Buy the system once and capture the full savings for its 25-year life. Bustan Energy delivers turnkey EPC and ongoing O&M.
Solar EPC (Engineering, Procurement and Construction) means you own the solar system outright. For Thai factories and commercial sites with capital to invest, EPC delivers the lowest cost per kWh and the strongest long-term return. Bustan Energy handles design, equipment, installation, PEA/MEA approval and maintenance, turnkey.
What turnkey EPC includes
Under an EPC contract Bustan Energy delivers the entire project end to end: engineering design, Tier-1 equipment procurement, structural and electrical installation, PEA/MEA permitting and commissioning. You receive a fully working, grid-tied solar system that you own outright, with documented performance and warranties. One contract, one accountable partner.
- Full engineering, design and load analysis
- Tier-1 panels and inverters procured for you
- Structural, electrical and grid-tie installation
- Commissioning, handover and warranty package
The financial case for owning
When you own the system, every kWh it produces after payback is effectively free for the rest of its 25-year life. EPC typically delivers the lowest lifetime energy cost and the highest ROI of any model, plus the asset sits on your balance sheet and may qualify for Thai investment incentives. Payback on commercial rooftops is often a few years.
- Lowest cost per kWh over the system lifetime
- Strong ROI with multi-year payback, then near-free power
- Solar asset added to your balance sheet
- Potential eligibility for Thai investment incentives

Frequently asked questions
What is the difference between EPC and PPA?
With EPC you pay for and own the system, capturing all savings and the best long-term ROI. With a PPA, Bustan owns the system and you buy the power. EPC suits businesses ready to invest capital.
How long until a solar EPC system pays back?
Commercial rooftop systems in Thailand often pay back within a few years, depending on consumption, tariff and roof size. After payback the electricity is effectively free for the rest of the 25-year life.
Do you handle PEA/MEA approval for EPC projects?
Yes. Every EPC project includes full PEA or MEA application, interconnection and metering coordination, plus commissioning, so your system is properly approved and grid-tied without extra work for you.
What equipment do you use?
We install Tier-1, bankable panels and inverters selected for Thailand's heat and humidity, backed by manufacturer warranties. Quality components protect long-term yield and the value of the asset you own.
Can Bustan maintain the system after installation?
Yes. We offer ongoing O&M with live monitoring, scheduled cleaning and inspections, and fast fault response, so your owned system keeps performing at spec and your ROI stays protected.
