Find out how many solar panels you need, what they'll cost, and how much you'll save — in under 2 minutes. No jargon. No sales calls. Just honest numbers.
No jargon. No sign-up. Just honest numbers.
We ask about your home, bills, and habits — in plain language, not engineer-speak.
Based on your location, sun hours, and electricity bill — we calculate your perfect system.

Armed with real numbers, you can have confident conversations — no more guessing.
Take a few minutes. We promise it's easy — and even a little fun.
Based on your answers, here's what we recommend.

Every estimate on this page is built from three layers of real data — not generic averages. First, climate: we use sun-hour data derived from NASA's POWER Project (30-year satellite climatology) for your region, the same dataset used by energy researchers. Second, tariffs: we maintain localised electricity rates and solar policy rules for each supported country — for example, Malaysia's estimates follow the Solar ATAP net-billing scheme that replaced NEM in January 2026, where self-consumption matters more than export. Third, system assumptions: we apply conservative, industry-standard loss factors for panel efficiency, inverter losses, heat and wiring, so the numbers you see err toward realistic rather than optimistic.
The result is an estimate typically within 10–20% of a professional site assessment. It can't replace one — your exact roof direction, shading and structure need human eyes — but it tells you honestly whether solar is worth pursuing before anyone tries to sell you anything.
We don't see your roof's structural condition, panel-level shading from nearby trees, or your utility's connection-approval queue. Estimates also assume current tariff and policy rules, which governments change — we update these when they do (as we did when NEM ended). Treat your result as a well-informed starting point for conversations with installers, not a quotation.
Sunlytic uses industry-standard formulas with real utility tariff data, region-specific sun-hour averages, and conservative system loss factors. Estimates are typically within 10-20% of what a professional site assessment will quote. Always get at least 3 professional quotes before deciding.
Yes, Sunlytic is completely free for users. We're supported by advertising and partnerships with certified solar installers.
Sunlytic supports 10 countries with localised tariffs and sun-hour data: Malaysia, Singapore, Indonesia, Philippines, Thailand, India, Australia, United Kingdom, United States, and a generic global option.
The full quiz takes about 2 minutes. You answer 9 simple questions about your location, electricity bill, roof, EV ownership, and battery interest, then immediately see your estimate.
No. We only share your contact details with up to 3 certified installers if you explicitly request quotes. We never sell data, and you can request deletion at any time. See our Privacy Policy for full details.
