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.
Every honest number on this site comes from the same AI engine — not a person deciding what's easiest to sell you.
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.
Ask our chatbot anything about solar in plain language, any time — trained on Helio's own knowledge base, not a generic script.
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.
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.
Every other solar company in Thailand sells hardware. Helio sells a decision you can trust — then stands behind it for 25 years.
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.
Vetted installers, one warranty, one point of contact. You deal with Helio, never a subcontractor.
Every customer gets the same free app, warranty and support — battery or not, big system or small.
The Free HELIO OS app BETA uses AI to monitor your system, flag issues early, and check in — long after install day.
Bill, roof, and what you actually want from solar.
A goal-matched package, with the real payback shown upfront.
A vetted, licensed installer — managed end to end by Helio.
The free HELIO OS app BETA watches your system so you don't have to.
Not sure which one fits? The calculator asks about your goals first and rules out the packages that don't make sense for you.
Generate your own power during the day and cut what you buy from the grid — the core saving, before anything else.
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.
Every kWh you generate is a kWh not burned from fossil-fuel grid power — a direct, measurable contribution.
Hybrid packages with a battery (Balance, Freedom, Ultimate) keep essential power flowing when the grid goes down.
Ultimate pairs solar generation with EV charging, so your car runs on sunlight instead of grid power.
Every home and business in Thailand should be able to trust one clear voice on solar — not five 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.
Three questions. Two minutes. An honest answer, not a sales call.
