Real numbers, published openly — the table below is what we actually charge, not a teaser before a sales call. Every price includes Tier-1 hardware, installation, protection devices, commissioning and PLN paperwork where relevant. The only honest caveat: final quotes are fixed after a survey, because roof type and electrical condition genuinely move the number. They never move it after the quote is signed.

Payback Calculator: Your PLN Bill to kWp, Price and Years
The calculator below uses the grid-tied package prices above and PLN's 2026 residential tariffs. For the full method and a worked villa example, read how fast solar pays back in Bali.
Solar payback calculator for a Bali villa
Enter your monthly PLN bill. The calculator picks a system from our published package prices and shows the yearly saving and payback.
Indicative estimate: PLN tariff IDR 1,444.70/kWh (R-1) or 1,699.53/kWh (R-2, R-3), 128 kWh per kWp per month, on-grid only, no credit for exported power. The fixed quote follows a site survey.

What Moves the Price
Roof type and access. Flat concrete is the cheapest surface; clay tile needs under-tile hooks; steep or multi-level roofs add scaffolding time. Electrical condition. An old distribution board may need upgrading before a system can be connected safely — we quote it separately and honestly. Single vs three-phase. Three-phase villas need either a three-phase inverter or careful phase balancing. Panel brand tier. Our default is Tier-1; premium brands add 10–15%. Distance to the coast. Salt-zone hardware (stainless fasteners, sealed enclosures) adds a small margin within a kilometre of the surf — see what that means in Uluwatu or Canggu.
What never moves the price: your area (no travel surcharges anywhere in south Bali), and the quote itself once signed. Payback arithmetic for these numbers is laid out in our solar cost and payback article.
