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 kWP to 500 kWP+..

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 Battery Energy Storage (for Businesses)

Battery isn’t just for home batteries—it’s a powerful tool for businesses too. With a battery energy storage system (BESS), factories, malls, data centers, cold storage, and hospitals in Thailand can cut costs, improve reliability, and get more value from solar.

Why it helps

Lower electricity bills: Use stored energy when grid prices are high.

More reliable power: Keep critical loads running during outages.

Better use of solar: Store daytime solar for evening or cloudy periods.

Support the grid: Reduce strain during peak demand.

Key applications

Demand charge management:Utilities often charge extra based on your highest peak usage. A battery energy storage system supplies power during those peaks, helping reduce that charge.

Peak Shaving: Charge the battery during off-peak hours, then discharge at peak times. This smooths your load profile and cuts energy costs.

Backup power & Resilience: For critical operations—like data centers, hospitals, manufacturing lines—a battery provides fast, reliable backup to protect equipment and avoid downtime.

Renewable Integration: Pair your solar with a BESS to store excess daytime energy and use it later. This boosts self-consumption and helps meet sustainability targets.

Best solutions for your site

Every facility is different. We design each system to fit your goals, space, and budget:
