Home / Residential Solar
For Homeowners

Solar built around how your household actually uses power.

A rooftop system sized to your real consumption — not a generic package — so every ringgit invested earns its keep.
Why Residential Solar

Your bill, offset at the source.

Under Solar ATAP — the programme that replaced NEM 3.0 on 1 January 2026 — the power your panels generate is used in your home first, offsetting electricity you'd otherwise buy from TNB. Surplus exported to the grid earns credit at the prevailing Energy Charge, capped by your MAQ. Because ATAP credits don't carry forward month to month, sizing the system correctly matters more than it used to.

Government incentive

There's a RM3,000 rebate on the table right now.

PETRA's SuRIA Home incentive pays eligible domestic Solar ATAP customers RM600 per kWac installed, capped at RM3,000 — a one-time cash rebate on top of your bill savings. It's tied to available quota and to systems commissioned before 31 December 2026.
  • Applies to domestic Solar ATAP installations only
  • A 5 kWac system claims the full RM3,000 cap
  • Commissioning — not signing — is what meets the deadline
  • We handle the SEDA application as part of your install
Rebate is subject to PETRA/SEDA programme terms, eligibility criteria, and remaining quota. We confirm your eligibility in writing before you commit.

How much could you save?

Five bill sizes with the system we'd realistically fit to each. The percentage is highest on smaller bills — a modest system covers proportionally more of a modest household, and dropping under 600 kWh/month also removes the retail charge, AFA and SST from your bill entirely.

Modelled on the RP4 domestic tariff (44.43 sen/kWh combined for usage under 1,500 kWh) at 3.8 kWh/kWp/day — a realistic Malaysian yield. Self-consumed generation avoids the full combined rate; surplus exported under Solar ATAP is credited at the Energy Charge only (27.03 sen/kWh), capped by MAQ and forfeited if unused. Percentages fall as bills rise because larger households need proportionally more roof than most have. Your figures are confirmed at site inspection.

RM230–260

Modelled monthly saving for a 6 kWp system on a ~1,200 kWh household, under the RP4 tariff and Solar ATAP export terms.

RM 33,500

Cumulative 10-year saving for the same household, allowing 0.5%/yr panel degradation and 3%/yr tariff escalation.

7–10 years

Typical payback after the SuRIA rebate — shortens if TNB tariffs rise, as they did by 13.6% under RP4.
Common questions

Residential solar, answered.

With solar photovoltaic technology, sunlight is converted into electricity using semiconducting materials in each panel. That electricity is used in your home first, with any surplus exported to the grid under Solar ATAP.

Two ways. First and most importantly, every kWh your panels produce that you use directly is a kWh you don't buy from TNB — that's where most of the saving comes from. Second, surplus you export earns a credit under Solar ATAP at the prevailing Energy Charge, up to your Maximum Allowable Quantity (MAQ = system kWac × 5 sun hours × billing days). Note that ATAP credits are use-it-or-lose-it: unused credit at the end of a billing period is forfeited, which is why we size systems against your actual consumption rather than your roof area.

Typically 7 to 10 years after the SuRIA rebate, depending on your system size, how much of your generation you use directly, and your tariff. Households that use more electricity during daylight hours sit at the shorter end. Rising tariffs shorten it further — the RP4 restructure raised the base tariff by 13.6%. Panels carry a 25-year performance warranty, so the years after payback are the return.

Starter packages begin around RM18,000. Financing is available from as low as RM500/month over 36 months with 0% interest, subject to bank approval.
