Putting solar on a Singaraja home isn't really about saving money. It's about taking control of your home's electricity, so when PLN tariffs rise, blackouts hit, or the Bali grid stumbles, your house doesn't move with it. Monthly savings show up too, but they're a bonus from a bigger decision: stop being fully dependent on a single provider you have no leverage over.
Singaraja happens to be a sensible place to make that call. Irradiance is 5.0 to 5.3 kWh per m2 per day, the North Bali coast sits in Mount Batur's rain shadow with less rainfall than the south, and PSH stays consistently high. The neighborhoods that fit best: Buleleng Tengah, Banjar Bali, Sukasada Tengah, Kampung Anyar, Penarukan. Whether your specific home fits is what we figure out together.

TL;DR
- Independence level: 2.5 kWp in Singaraja covers about 62% of a 2200 VA home with a Rp 1.2 million bill. The rest comes from PLN, but you're no longer 100% exposed to the tariff.
- Typical setup: 2 to 5 kWp grid-tied or hybrid (panels, inverter, mounting, install, warranty). Optional battery for blackout backup.
- Singaraja climate: irradiance 5.0 to 5.3 kWh per m2 per day. North Bali coastal, Mount Batur rain shadow, lower rainfall than southern Bali.
- Investment: Rp 28 to 75 million depending on size. Payback 4 to 6 years on a Rp 1 to 1.5 million monthly bill, then near-free electricity for 20 more.
- Partner installer: our partner technician team covers all of Indonesia, Bali included, with experience across varied residential roof conditions.
- Not yet a fit if: your bill is under Rp 800,000/month, your roof has heavy shading, or you're moving within 5 years.
Solar prices in Singaraja, real numbers April 2026
Rough range we've seen from installer quotes in Bali as of April 2026:
| System | Fits | Complete package | Includes |
|---|---|---|---|
| 2 kWp grid-tied | Bills Rp 800,000 to 1.2 million | Rp 28 to 35 million | Panels, inverter, mounting, install, 25-year panel + 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, plus 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 your meter. Singaraja sits on the north coast, so logistics from Denpasar add a small transport line, but it's not a big deal.
What to watch for in any installer's quote:
- Panel and inverter brand named, or just "or equivalent"? A clear spec means a serious installer.
- Product warranty vs install warranty. Panels are 25 years standard, inverters 5 to 10 years. Workmanship warranty should be 2 to 5 years.
- ESDM certification or SLO. Required for any grid-tied system that exports to PLN.
Investment vs PLN dependency, rough math
Independence isn't free. But the math also isn't as scary as most people think. Assumptions we use (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
- Singaraja irradiance: ~5.15 kWh per m2 per day average
- 1 kWp panel output: ~115 to 130 kWh per month
For a 2200 VA home with a Rp 1.2 million monthly bill, installing 2.5 kWp:
- Monthly output: 2.5 kWp × 122 kWh = 305 kWh
- Covers ~62% of your home's electricity: 305 kWh × Rp 1,444 = ~Rp 440,000/month no longer flowing to PLN
- Per year: ~Rp 5.3 million that used to be a PLN bill, now stays in your home
- Investment: ~Rp 40 million
- Payback: 40 million / 5.3 million = ~7.5 years (conservative). The remaining 17 years run on your own electricity, near zero cost.
If your daytime use is heavy (working from home, daytime AC, electric stove), coverage can hit 70 to 80% and payback drops to 5 to 6 years. What you're really buying isn't just savings, it's lasting independence: 25 years where your home is far less exposed to PLN tariff hikes, rupiah swings, and short-term outages (with hybrid + battery).

Is Singaraja a fit? Climate, roof, availability
Climate: yes. Singaraja's irradiance averages 5.0 to 5.3 kWh/m2/day year-round. Mount Batur's rain shadow gives the area less rainfall than southern Bali, so PSH stays high. The wet season (November to March) is still productive, just down about 20% from peak.
Roof: ideally north-facing (Singaraja is in the southern hemisphere), tilt 10 to 30 degrees. East- or west-facing still works, output drops 10 to 15%.
Shading: check tall trees (Buleleng has plenty of coconut and jackfruit trees), neighboring buildings, or water towers that cover the roof between 9 a.m. and 3 p.m.
Installer: our partner technician team covers all of Indonesia, Bali included, with experience on varied residential roofs from coastal villas to standard Buleleng homes. Equipment ships from Denpasar or Surabaya, so timeline is usually 2 to 3 weeks after the survey.
When solar isn't yet for you
Independence is good, but not for everyone right now. Four cases where we say wait:
- Your PLN bill is under Rp 800,000/month: your dependency on PLN is already small. Audit usage first; you might need efficiency more than solar.
- Heavy roof shading: output drops a lot, the energy control you're buying becomes half-finished. Better to trim trees first or work the roof position out.
- Moving within 5 years: the investment doesn't pay back before you go, and the system isn't easy to relocate.
- You actually need blackout backup, not long-term control: grid-tied solar doesn't run when PLN goes down. Hybrid (solar + battery) or a generator fits better if that's your top priority.
Frequently asked questions
Roughly Rp 35 to 45 million for a 2.5 kWp grid-tied package (panels, inverter, install, warranty). Payback is 4 to 6 years on a Rp 1 to 1.5 million monthly bill. The site survey resets the number based on your actual roof condition.
