ย่านประวัติศาสตร์ฝั่งธนบุรี ใกล้วงเวียนใหญ่ มีอาคารพาณิชย์และที่พักอาศัยที่สามารถติดโซลาร์เซลล์ลดค่าไฟ
Around Wong Wian Yai and Charoen Nakhon Road, old Thonburi is packed with low-rise shophouses and commercial blocks that sit in long continuous rows. Our team is used to reinforcing frames and routing cables on buildings like these, so installing solar in Thon Buri reliably cuts power bills from air-conditioning and chillers for shops and homes. Every job starts with a free on-site survey.

How many years until solar pays back?
There is no single payback period for every project. It must be calculated from installation price, system size, daytime self-consumption, tariff, roof orientation and pitch, shade, degradation and maintenance. QuescoSolar states the assumptions used in its assessment before quoting.
Which areas does QuescoSolar serve?
QuescoSolar installs solar across all 50 districts of Bangkok plus the surrounding provinces — Pathum Thani, Nonthaburi, Samut Prakan, Samut Sakhon and Nakhon Pathom — covering Ramintra, Lat Phrao, Sai Mai, Don Mueang, Lak Si, Bang Khen, Chatuchak, Khlong Sam Wa, Min Buri, Lat Krabang, Bang Na, Sathon and many more.
How much does solar buy-back pay?
Under the Net Metering / People’s Solar programmes, EGAT buys back excess power at about 2.20 THB/unit (per 2024-2026 announcements) for 10 years. However, the fastest payback comes from designing the system to self-consume most power during the day rather than selling it back.
