Putting solar on a residential roof in Ubud isn't really about saving money. It's about energy control for your home, so when PLN tariffs rise, blackouts hit, or the Bali grid hiccups, your home doesn't shake with it. Monthly savings still happen, but they're a bonus on top of a bigger decision: stepping out of full dependence on a single provider whose pricing you can't influence.

Ubud is a sensible city to make this call, with a few climate caveats. Irradiance runs 4.8 to 5.0 kWh per m2 per day, and the jungle terrain of Gianyar produces more shading and morning fog than coastal Bali. PSH (peak sun hours) is slightly lower than Kuta or Denpasar, but still solid. Best-fit residential areas: Ubud Tengah, Padangtegal, Pengosekan, Tegallalang, and Mas. Whether it fits your specific home is what we work out together.
If you own a villa in Ubud, the math is similar but the load profile is bigger. See our off-grid solar guide for Bali villas for detailed sizing.
TL;DR
- Independence level: a 2.5 kWp system in Ubud covers about 58% of a 2200 VA home with a Rp 1.2 million bill. The rest still comes from PLN, but you're no longer 100% exposed to its tariff.
- Common system: 2 to 5 kWp grid-tied or hybrid with panels, inverter, mounting, install, and warranty. Battery is optional for blackout backup.
- Ubud climate: irradiance 4.8 to 5.0 kWh per m2 per day. Jungle terrain, frequent morning fog, more canopy shading than coastal Bali.
- Investment: Rp 28 to 75 million depending on size. Payback 4 to 6 years at bills of Rp 1 to 1.5 million per month, then near-free electricity for the next ~20 years.
- Partner installer: our partner technician team covers all of Indonesia, including Bali. They've installed across varied residential roof conditions.
- Doesn't fit if: your bill is below Rp 800,000 per month, your roof is heavily shaded (common in Ubud), or you plan to move within 5 years.
Solar panel pricing in Ubud, real April 2026 numbers
Rough range we're seeing from Bali-area installer quotes as of April 2026:
| System | Fits | Complete package | Includes |
|---|---|---|---|
| 2 kWp grid-tied | Bills Rp 800k to 1.2 million | Rp 28 to 35 million | Panels, inverter, mounting, install, 25-year panel warranty + 5-year inverter warranty |
| 2.5 kWp grid-tied | Bills Rp 1 to 1.5 million | Rp 35 to 45 million | Same |
| 3.5 kWp grid-tied | Bills Rp 1.5 to 2 million | Rp 50 to 60 million | Same |
| 5 kWp grid-tied | Bills Rp 2 to 3 million | Rp 60 to 75 million | Same |
| 5 kWp hybrid (+5 kWh battery) | Same, with blackout backup | Rp 90 to 110 million | Plus battery storage |
The range is wide because it depends on panel and inverter brand (Jinko vs Canadian vs LONGi, Sungrow vs Huawei vs SMA), roof condition, and the cable run from panels to the meter. Some Ubud access roads are narrow at the gang level, so labor can run a bit higher.
What to watch for in any installer quote:
- Are the panel and inverter brands specified, or listed as "or equivalent"? Clear specs mean a serious installer.
- Product warranty vs installation warranty. 25 years on panels is standard. Inverters 5 to 10 years. Installation warranty ideally 2 to 5 years.
- ESDM or SLO certification. Required for grid-tied systems that export to PLN.
Investment vs PLN dependence, rough math
Independence isn't free. But the math also isn't as scary as people often assume. Working assumptions (April 2026):
- R-1 tariff for 1300 to 2200 VA: Rp 1,444 per kWh
- R-1 tariff for 3500 to 5500 VA: Rp 1,699.53 per kWh
- Ubud irradiance: ~4.9 kWh per m2 per day average
- Output per 1 kWp panel: ~110 to 125 kWh per month
A 2200 VA home, Rp 1.2 million monthly bill, installs 2.5 kWp:
- Monthly output: 2.5 kWp x 117 kWh = 293 kWh
- Covers ~58% of your home's electricity: 293 kWh x Rp 1,444 = ~Rp 423,000 per month no longer flowing to PLN
- Per year: ~Rp 5.1 million that used to feed PLN now stays in your home
- Investment: ~Rp 40 million
- Payback: 40 million / 5.1 million = ~7.8 years (conservative). The remaining 17 years of panel life is near-zero-cost electricity.
If your daytime usage is heavy (work-from-home, daytime AC, electric cooking), coverage can hit 70 to 80% and payback drops to 5 to 6 years. What you're buying isn't just savings; it's durable independence: 25 years of your home being far less exposed to PLN tariff hikes, rupiah swings, and short-term outages (if you go hybrid + battery).

Does Ubud fit? Climate, roof, availability
Climate: yes, with caveats. Ubud irradiance averages 4.8 to 5.0 kWh per m2 per day, slightly lower than coastal Bali. Jungle terrain means frequent morning fog and denser cloud cover during the November to March wet season (output dips ~25% from peak). Still viable, with output only slightly below south Bali.
Roof: ideally north-facing (Ubud is in the southern hemisphere) with a 10 to 30 degree pitch. Ubud villa roofs often use alang-alang or traditional terracotta tile, and need an engineering check.
Shading: high priority in Ubud. Many homes are surrounded by tall trees (coconut, jackfruit, banyan). Check shadows between 9 a.m. and 3 p.m. more carefully than in other cities. If shading is severe, consider trimming first or installing on a more open building elsewhere on the compound.
Installer: our partner technician team covers all of Indonesia, including Bali. They've installed across varied villa roof conditions, including traditional structures. Equipment ships from Denpasar (~30 minutes), so the timeline is typically 2 to 3 weeks after the survey.
When solar isn't a fit yet
Independence is good, but it isn't right for everyone right now. Four situations where we suggest waiting:
- Your PLN bill is below Rp 800,000 per month: your dependence on PLN is already small. Audit your usage first; you may need efficiency more than solar.
- Heavy roof shading: in Ubud this is the most common risk. Output drops a lot, and the energy control you're paying for becomes half a thing. Better to wait until you can trim trees, or use a more open building on the compound.
- Plan to move within 5 years: the investment hasn't paid back when you leave, and the independence doesn't relocate easily.
- What you actually need is blackout backup, not long-term control: grid-tied solar doesn't run when PLN goes down. Hybrid (solar + battery) or a generator is a better fit if that's the priority.
Frequently asked questions
Rough estimate Rp 35 to 45 million for a 2.5 kWp grid-tied package (panels, inverter, install, warranty). Payback 4 to 6 years at bills of Rp 1 to 1.5 million per month. Our partner technician team will recalculate at survey based on actual roof condition.
