Thailand's independent solar advisor

Solar for ALL.
Not just those who know how to shop for it.

Helio isn't a solar EPC or distributor. We're the advisor that tells you the right-sized system for your goals, then manages every step — one contract, one warranty, one point of contact, for the life of your system.

What going solar actually gets you

Lower electricity bills Up to ฿200,000 tax deduction Real environmental impact Backup during outages Ready for your EV

Lower electricity bills

Generate your own power during the day and cut what you buy from the grid — the core saving, before anything else.

Up to ฿200,000 tax deduction

Thai individual taxpayers can deduct qualifying rooftop systems up to 10 kWp under Royal Decree No. 805 (2026), for installs completed 2026–2028. Terms apply — see FAQ.

Real environmental impact

Every kWh you generate is a kWh not burned from fossil-fuel grid power — a direct, measurable contribution.

Backup during outages

Hybrid packages with a battery (Balance, Freedom, Ultimate) keep essential power flowing when the grid goes down.

Ready for your EV

Ultimate pairs solar generation with EV charging, so your car runs on sunlight instead of grid power.

Powered by AI

AI runs the recommendation, not a sales quota

Every honest number on this site comes from the same AI engine — not a person deciding what's easiest to sell you.

AI-matched sizing

Our calculator weighs your bill, roof, time-of-use pattern, and goal to size a system mathematically in under 3 minutes — not a salesperson's gut feel. It's Helio's own tool, not a third-party redirect, and opens right in your browser.

AI-monitored performance

The Free HELIO OS app BETA uses your live generation data to catch underperformance or faults early — often before it shows up on your bill.

What you're actually getting

A real system on your real roof — not a rendering built to impress

Every Helio proposal is sized to your specific roof, shading, and consumption pattern before installation begins. As our first installs come online, this space becomes real customer photography — that's a deliberate choice over generic stock imagery.

Illustrative diagram — will be replaced with real installation photography.

Why Helio is different

We're not selling panels. We're managing your outcome.

Every other solar company in Thailand sells hardware. Helio sells a decision you can trust — then stands behind it for 25 years.

An advisor, not a salesperson

Our AI-powered calculator recommends the smallest system that meets your goal — never the biggest one to sell. If usage is too low to make sense, it says so.

We manage everything

Vetted installers, one warranty, one point of contact. You deal with Helio, never a subcontractor.

Solar for ALL

Every customer gets the same free app, warranty and support — battery or not, big system or small.

A partner for 25 years

The Free HELIO OS app BETA uses AI to monitor your system, flag issues early, and check in — long after install day.

Not sure which one fits? The calculator asks about your goals first and rules out the packages that don't make sense for you.

Solar for ALL isn't a slogan.

Every home and business in Thailand should be able to trust one clear voice on solar — not a pile of conflicting sales pitches. That's the gap Helio exists to close: honest advice first, so more people go solar sooner, not just the ones who already know how to shop for it.
