The questions we hear most, answered the same way we'd answer them on a call.
No — and that's intentional. Helio manages a network of vetted, licensed EPC partners who carry out the physical installation. You sign one contract with Helio, and your warranty and support sit with us, not the installer. This lets us hold every partner to one consistent quality standard instead of you having to evaluate installers yourself.
Our calculator asks about your bill, your roof, and your goal (lowest cost, balance, or full independence), then recommends the smallest package that meets that goal — with the real, unpadded payback period shown alongside it. If a package would take an unreasonably long time to pay back, we disclose that honestly rather than hide it.
Rooftop solar for a shared building usually needs juristic-person approval and a different technical approach than a single house. Rather than force an inaccurate sizing estimate, we'll take your contact details and have a Helio advisor follow up directly.
We'll tell you directly. If your bill is too small for any package to pay back in a reasonable time, our calculator flags this rather than recommending a system anyway — and explains what would need to change, typically higher daytime or overall consumption, before it's worth revisiting. We'd rather you come back in a year than regret a purchase today.
No — it typically works the other way. As an aggregator, Helio channels volume across a small number of strategic EPC partnerships rather than owning installation crews ourselves, which usually gets us more competitive equipment and labor pricing than a homeowner could negotiate alone with a single installer. You get that aggregated rate, plus one advisor relationship and one warranty instead of comparing five uncertain quotes yourself — you're benefiting from our buying power, not paying a markup for it.
Yes, when installed correctly — which is exactly why Helio only works with licensed, certified EPC partners and requires surge and lightning protection (Type II SPD) as standard on every install, not an optional extra. Your roof's structural capacity is checked during the free site assessment before any installation is scheduled.
Battery systems in our packages use certified lithium battery technology installed to manufacturer and electrical code specifications, including proper ventilation and placement. Your installer will confirm the safe location for your specific property during the site assessment.
Grid-tie packages (Saver, Saver+) automatically shut down during a grid outage, by design — this is a safety standard, so the system doesn't feed power back into lines utility workers may be repairing. Hybrid packages with a battery (Balance, Freedom, Ultimate) can continue powering your home from stored energy during an outage, within the battery's capacity.
Yes, from day one. Some providers in the market offer $0-upfront subscription models where you never actually own the equipment — with Helio, the system is yours, whether you pay upfront or use financing.
Financing options depend on the package and are discussed during your proposal — a Helio advisor will walk you through what's available for your specific situation rather than quote a generic rate that may not apply to you.
Warranty terms vary by component (panels, inverter, battery) and are set out clearly in your contract before you sign — ask us for the specifics for your package.
Yes — under Royal Decree No. 805 (2026), Thai individual taxpayers can deduct up to ฿200,000 from taxable income for a qualifying grid-connected rooftop solar system up to 10 kWp, for installations completed between 3 March 2026 and 31 December 2028. You must be the registered owner of the electricity meter and use a certified, VAT-registered installer with a proper e-Tax invoice — all of which a Helio-managed install satisfies. This is general information, not personal tax advice — please confirm your specific eligibility with a licensed tax advisor.
It's Helio's monitoring app, currently in beta and free to every customer. It tracks your system's generation and consumption and flags issues — like underperformance or a fault — early, so problems get caught before they cost you real money.
It's actively being improved, and the label keeps our options open on future pricing as the product matures — but every customer gets it under the same terms, regardless of package size.
Helio — always one number, one contact, regardless of which EPC partner physically installed your system.
It's functional, not decorative. The same recommendation engine that sizes your package on our calculator also powers our LINE chatbot's answers, and the Free HELIO OS app (Beta) uses your system's live generation data to flag underperformance or faults early — often before it would show up as a bigger bill.
