Our Solar Solutions

At Thai Solar Power, we build smart solar systems that match your real energy needs—whether you own a home, a shop, or a large commercial site. We don’t offer one-size-fits-all kits. Instead, we design the right solution for your space, usage, and budget. We offer on-grid, hybrid (solar + battery), and off-grid systems , plus installation, after-sales support, and flexible packages.

For Homes

Solar for Homes (1-phase or 3-phase)

If you’re using most of your electricity during the day, a simple on-grid solar system is the best way to save money. We help you:

  • Power your home directly from the sun
  • Cut electricity bills (up to 70% savings)
  • Charge your EV during the day—for free!
  • se your roof or carport to generate energy

Have heavy evening usage (EV, air conditioning, pool pump)? We’ll design a hybrid system with a battery that stores extra solar power for night-time use.

No access to the grid or using diesel? We offer off-grid systems with battery and inverter to give full energy independence.

  • Systems from 3 kW to 20 kW
  • Rooftop, carport, or ground-mounted
  • Clean design, strong warranties, and full support

we design a custom system to save the most and produce the most.

For Businesses & Commercial

Solar for Businesses & Commercial Buildings

We help small and large businesses across Thailand cut energy costs with smart solar design. In most areas, electricity is stable—so there's no need for batteries. A good on-grid system can reduce demand charges, support peak-hour usage, and bring fast ROI.

We’ve installed solar systems for:

  • Shops and small businesses
  • Hotels, schools, and hospitals
  • Warehouses and logistics centers
  • Factories and industrial buildings

We assess your load profile, operating hours, and available space, then recommend the best solar size—from 20 kW to 500 kW+.

If you don’t have roof space, we can use your parking area (solar carport) or nearby land (ground mount).

Need a Battery? Only If You Truly Need It

We only offer battery storage when your business requires backup or grid support—no upselling. Our goal is to maximize savings, not overspend.

Want Solar Without Upfront Cost?

We offer investment options for selected commercial projects like hotels, factories, schools, and resorts.

We build and maintain the system—you enjoy lower electricity bills with no investment.

What We Offer

We provide complete support under one roof:

  • Solar Products (panels, inverters, batteries)
  • Installation by professional engineers and technicians
  • After-sales service and system monitoring
  • Different packages based on your needs and budget (product only, full install, or full EPC service)

C&I Energy Storage

Energy storage solutions are not limited to residential applications. Commercial and industrial sectors also benefit from the integration of energy storage systems into their operations. Whether it's reducing demand charges, increasing grid resilience, or supporting renewable energy adoption, commercial and industrial energy storage has the potential to revolutionize the way businesses manage their energy consumption.

Applications of C&I Energy Storage

Demand Charge Management: Commercial and industrial facilities often incur high demand charges based on their peak power usage. Energy storage systems can help reduce these charges by providing stored energy during peak demand periods, reducing reliance on the grid and expensive utility rates.

Peak Shaving: By storing excess energy during off-peak hours, businesses can reduce their electricity consumption during peak times. This strategy not only reduces costs but also helps stabilize the grid by alleviating stress during periods of high demand.

Grid Resilience and Backup Power: For critical operations, such as data centers, hospitals, or manufacturing facilities, maintaining uninterrupted power supply is crucial. Energy storage systems provide reliable backup power, ensuring continuity during power outages and protecting valuable equipment and data.

Renewable Integration: Commercial and industrial sectors are increasingly adopting renewable energy sources to meet sustainability goals. Energy storage systems facilitate the integration of renewables by storing excess energy generated from sources like solar or wind, making it available during periods of high demand or when renewable generation is low.

Customized Energy Storage Solutions

Each commercial or industrial facility has unique energy requirements and operational constraints. It is crucial to work with an experienced energy storage provider who can tailor a solution to meet your specific needs. A thorough energy assessment, load analysis, and system design are essential to ensure optimal performance and maximum benefits.
