Solar solutions designed around your needs

A solar system should be designed around your home, your electricity use and what you want to achieve.

Some homeowners mainly want to reduce their monthly electricity bill. Others want battery backup during power cuts, while some need a complete off-grid system in an area without reliable access to the electricity network.

We begin by understanding your goals. Our engineers then design a system using carefully selected solar panels, inverters and battery storage. Our own installation team completes the work, tests the system and helps you understand how it performs.

Our solar solutions

Choose the right solar system for your home

Every property is different. We help you choose a system that matches your electricity consumption, location and budget.

Solar + Battery

Generate solar energy during the day and store excess power for use later. A hybrid system can reduce your electricity bill, increase energy independence and provide backup during power cuts.

Ask about solar + battery

Solar Without Battery

Use solar energy directly during the day and reduce the amount of electricity you buy from the grid. A cost-effective choice for homes with high daytime electricity use.

Ask about on-grid solar

Off-Grid Solar

Reliable electricity for homes, farms and buildings away from the public grid. We design complete systems combining solar panels, batteries and intelligent energy management.

Advanced battery systems for modern homes

Battery storage allows you to use more of the solar energy your home produces. It can also provide essential backup power when the electricity grid goes down.

We install modern lithium iron phosphate battery systems designed for safety, long service life and reliable performance. Systems can be configured for single-phase or three-phase properties and tailored to the required battery capacity.

Frequently asked questions

Solar power in Thailand

How do I know what size solar system I need?

The correct size depends on your electricity consumption, when you use electricity, your roof or available land and whether you want battery backup. Send us a recent electricity bill and we can help assess your needs.

Do I need a battery with my solar system?

Not always. An on-grid system can reduce electricity costs without a battery if you consume much of your power during the day. A battery allows you to store energy for later and can provide backup during power cuts.

Will ordinary solar panels work during a power cut?

A standard on-grid solar system normally shuts down when the grid fails. To maintain power during an outage, you need a correctly designed hybrid system with battery storage and backup functionality.

How much does solar installation cost in Thailand?

The cost depends on system size, battery capacity, equipment, roof conditions and installation requirements. We provide a recommendation and quotation based on your property and goals.

How long does it take for solar to pay for itself?

Payback time varies according to system cost, energy production, electricity usage and future electricity prices. We provide realistic projections based on your actual consumption rather than making a generic promise.

Do you install single-phase and three-phase systems?

Yes. We design and install both single-phase and three-phase solar and battery systems depending on the property’s electrical supply and requirements.

Do you provide support after installation?

Yes. We provide after-sales support and help customers understand and monitor the performance of their systems.
