Solar Payback in Sabah and Sarawak: Compare Your Bill and Full Quote
Decision details
Fits if: Homeowners in Sabah or Sarawak comparing solar proposals and deciding which assumptions to check.
Main drawback: Without the current tariff, load profile, site-specific system forecast and installed total, this page cannot give a payback period or savings figure.
Compare: Tariff on the bill; system kWh forecast and basis; self-use versus export; full installed/delivered quote; battery scope; written scheme confirmation.

Short answer: a monthly bill alone cannot tell you whether solar is worthwhile. To make a comparable estimate, use the tariff on your bill, the generation forecast for the proposed system and site, how surplus exports are credited, and the full installed price. Recorded schemes have different state terms: residential Sarawak NEMSS lists capacity-based subsidy tiers [source], while Sabah Solar Rakyat lists a capped rebate [source]. There is no general payback period or current Sabah/Sarawak tariff that applies to every home here.
The useful buying question is not only “what is the price?” but “what is included, and how was the savings estimate made?” Ask suppliers to compare the same scope—panels, inverter, battery if any, installation, delivery and required work—and show the self-use and export assumptions behind their estimate.
Check the scheme by state, not by monthly bill
| Programme | Published amount | What to confirm for your project |
|---|---|---|
| Sarawak, residential NEMSS | RM8,000 for 2–3.5 kWac; RM10,000 for >3.5–6 kWac; RM12,000 for >6–50 kWac. Contract window 1 January 2025 through 31 December 2026, subject to quota [source]. | The subsidy announcement specifies landed homes, one installation per account holder and exclusion of homes with existing solar. 2025 contracts may be submitted to SESCO for consideration [source]. Get written confirmation of eligibility, process and funds/quota. |
| Sabah, Solar Rakyat | RM1,000 per kWac, capped at RM4,000 from 4 kWac; applications in 2026–2028 or until funds are used [source]. | Confirm eligibility and programme availability before subtracting a rebate from the cost. Referenced capacity/export terms state 5 kWac single-phase or 10 kWac three-phase limits and export in the first 12 contract years at the gazetted energy-tariff rate [source]. Ask the supplier to explain the connection terms for your home. |
The listed amount depends on system capacity and programme terms; it is not selected from your monthly RM or kWh bill. A larger system is not automatically the better choice just because the rebate amount differs. Compare its added cost with the savings forecast from your own usage pattern.
Quote comparison worksheet
Copy these rows for each proposal before comparing totals:
| Item | Quote A | Quote B |
|---|---|---|
| State, connection type and system size: panel kWp / inverter kWac | ||
| Panel, inverter and (if included) battery make/model and quantity | ||
| Usable battery capacity; model and warranty scope | ||
| System kWh forecast and assumptions used | ||
| Expected self-use versus export; export credit rate used | ||
| System price, installation, delivery and other charges separately | ||
| Included approvals/connection work and who handles them | ||
| Final total and quote validity period | ||
| Rebate terms confirmed in writing and by whom |
If one quote includes a battery and the other does not, the totals are not comparable. Ask for a battery-free option or a battery price breakdown if offered. Do not treat one product price, one seller’s advertisement or a number from another state as a market price or proof that equipment is genuine.
A simple payback estimate—only after the inputs are complete
- Use 12 months of bills to establish current consumption and spend; bills describe use, not solar generation.
- Ask for a site-specific generation forecast. The post-install bill model should show self-use, export, export credit and charges that remain.
- Compare the full installed cost for the same scope. Subtract a rebate only after your project’s eligibility and amount are confirmed in writing.
- Simple payback = full installed cost after an approved rebate divided by forecast annual bill savings net of recurring costs. Use the site-specific forecast and stated export assumptions; if net annual savings are not positive, no finite simple payback can be calculated.
This is a simple estimate, not a return guarantee. There is no single tariff or savings rate to borrow for every Sabah and Sarawak account. In Sabah, confirm the export treatment and capacity limit that apply to your connection. In Sarawak, confirm the contract window, quota, account-holder conditions and existing-solar status before treating the subsidy as money you will receive.

Frequently asked questions
Is payback in Kuching the same as the Peninsula numbers I read?
Do not assume that period transfers. Ask for a calculation using the tariff on your bill, the proposed system's site-specific kWh forecast, self-use/export assumptions, and the full installed price. Costs and export rules can vary by state; a general-page figure is not an estimate for your home.
How much subsidy can I claim in Sarawak?
The residential NEMSS record lists RM8,000 for 2-3.5 kWac, RM10,000 for >3.5-6 kWac and RM12,000 for >6-50 kWac. It gives a 1 January 2025 through 31 December 2026 contract window, subject to quota and approval [source]. The subsidy announcement also specifies landed homes, one installation per account holder and exclusion of homes with existing solar; 2025 contracts may be submitted to SESCO for consideration [source]. Confirm project eligibility, process and available funds in writing; the listed amount is not an approval promise.
Does Sabah have a rebate? What about exporting surplus?
The Sabah Solar Rakyat record lists RM1,000 per installed kWac, capped at RM4,000 from 4 kWac, with applications open in 2026–2028 or until funds are used [source]. The referenced export terms set 5 kWac single-phase or 10 kWac three-phase limits and describe export credit during the first 12 contract years at the gazetted energy tariff rate [source]. Ask for written confirmation of the programme, capacity and export terms that apply to your connection.
How do I know whether a high quote includes a battery?
Do not compare the final totals alone. Ask each supplier to list panel capacity (kWp), inverter capacity (kWac), battery model and usable capacity if included, installation, delivery, included approvals/protection work, warranty, taxes and other charges. Compare proposals with the same scope. A price or label alone does not confirm a product's model, condition or authenticity.
