Solar power (rooftop) service
Welltek provides rooftop solar power services in Taiwan and Thailand — covering Power Purchase Agreements (PPA), engineering, procurement and construction (EPC), and operation & maintenance (O&M) — including the structural design and reinforcement work rooftop installations often require.
What we deliver

From structural reinforcement to delivery in 45 days
In Thailand, Constant Energy engaged Welltek to build a rooftop solar power system for Fuji Seal Packaging. When the factory roof proved unable to bear the panels' weight, Welltek Thailand's engineers reinforced the structure before installation — then delivered the mounting structure, power grid, inverter house, water-cleaning and monitoring systems, plus walkways and guardrails for safe future maintenance. By expanding a single subcontractor team into three working in parallel, Welltek completed the system in 45 days instead of the originally planned 120.
Solar that qualifies products for export
For manufacturers, rooftop solar is more than lower electricity bills — renewable energy use increasingly determines whether products qualify for export markets. Welltek handles the engineering, electrical and structural design and leads document submission for government approval, so clients get a compliant system without managing the process themselves.
