Electricity usage
Your monthly TNB bill helps estimate your likely system size, usage pattern, and possible solar savings.
Solar Plus Malaysia guide
Understand solar power in Malaysia before you decide.
Solar Plus is an information hub for homeowners and business owners exploring rooftop solar options, Solar ATAP basics, estimated savings, and practical installation steps.

Why solar now
Solar is easier to understand when the moving parts are separated.
Instead of pushing a quote first, this homepage explains the main decisions Malaysian users normally need to evaluate.
Solar ATAP
Solar ATAP is Malaysia’s current rooftop solar programme, affecting how exported solar energy is credited and how savings are calculated.
Roof suitability
Not every roof is equal. Orientation, shade, available space, and structure determine how much solar can realistically be installed.
Long-term ownership
Panels are only one part of the system. Inverter choice, warranty terms, monitoring, and upkeep shape the long-term value you receive.
2026 policy context
Solar ATAP is the key programme to understand now.
Solar ATAP is Malaysia’s current rooftop solar programme following the previous NEM framework. It helps eligible users offset electricity usage by exporting excess solar energy to the grid, based on the applicable programme rules.
Final eligibility, system capacity, fees, and approval may depend on current official guidelines, technical assessment, and your property condition. Always check the latest requirements before making a decision.
What Changed
Solar ATAP replaces NEM 3.0 as Malaysia's rooftop solar programme from 1 January 2026. It is regulated by the Energy Commission and implemented by SEDA under PETRA.
- No fixed national quota; applications are open year-round.
- Self-consumption is prioritised, with surplus exported to the grid.
- Domestic exports are credited at the prevailing retail tariff; non-domestic exports follow System Marginal Price.
- Credits do not carry forward month to month.
- Applications go through a SEDA Registered PV Service Provider via eATAP.
Actual rates and rules are set by SEDA. Refer to atap.seda.gov.my for current guidelines.
Who Matters
Solar ATAP is relevant to a wider set of properties than earlier NEM schemes.
- Homeowners with landed property, including terrace, semi-D, townhouse, or bungalow homes.
- Businesses operating from shoplots, offices, or commercial buildings.
- Industrial premises with factory or warehouse rooftops.
- Farms and agricultural facilities newly included under ATAP.
Roof ownership is a baseline requirement. The TNB account holder's name usually needs to match the applicant.
What To Check
Before starting an application, verify the details that shape eligibility and system sizing.
- TNB account holder details and ownership proof.
- Supply type: single phase or three phase.
- Roof condition, orientation, and structural load capacity.
- Average monthly electricity consumption and proposed system capacity.
- Whether your installer is a SEDA Registered PV Service Provider.
- Documents such as NRIC, recent TNB bills, and property title.
- Whether you may qualify for the SuRIA Home rebate.
Final eligibility, fees, and approval remain with SEDA and TNB based on the property's specifics.
System pathways
Different properties need different solar questions.
Homes
For terrace, semi-D, and bungalow homes, four things decide the right system: usage, meter phase, roof space, and shading.
- Typical landed-home review
- Single or three phase check
- Roof layout and shade review
Businesses
For offices, shops, and factories, daytime load and maximum demand usually decide whether solar pays off.
- Daytime consumption profile
- Technical assessment route
- Operational cost stability
Large facilities
Industrial sites need more careful feasibility checks, electrical infrastructure review, and staged project planning.
- High load and roof area
- Grid and safety requirements
- Procurement comparison
Realistic solar use cases for different property types.
These examples show how Solar ATAP questions change between homes, businesses, and larger facilities. Figures are illustrative and should be checked against current SEDA and installer guidance.
Residential scenario
Klang Valley homeowner cutting a RM400 TNB bill
A double-storey terrace owner facing rising monthly electricity bills can apply for Solar ATAP through a SEDA Registered PV Service Provider (RPVSP), install a 4-6kW rooftop system, and offset most of their daytime consumption. Surplus is exported at the prevailing retail tariff, and the household may qualify for the SuRIA Home rebate to reduce upfront installation cost, turning a fixed monthly bill into a smaller, more predictable one.
Commercial scenario
Shoplot F&B operator lowering operating costs
A corner shoplot running daytime kitchen and cooling loads can install a 15-30kW system under Solar ATAP's non-domestic terms, self-consume the bulk of generation during trading hours, and export surplus at System Marginal Price (SMP). This directly reduces commercial TNB charges during peak operating windows and shields the business from future tariff hikes, protecting margins that would otherwise thin as electricity costs rise.
Industrial scenario
SME manufacturer meeting cost and ESG targets
An SME factory with a 2,000m² metal deck roof can deploy a 100-300kW Solar ATAP system to offset weekday production loads, export surplus energy at SMP, and generate documented emissions reductions. This addresses two pressures at once: the operational cost of running heavy machinery on TNB power, and the growing sustainability requirements from export buyers and ESG-conscious clients seeking lower Scope 2 emissions.

FAQ
Questions a solar information site should answer clearly.
Is this site an installer?
No. Solar Plus is not a solar installer or direct sales company. It is a solar knowledge hub created to help Malaysians learn about solar energy, compare key information, and make more informed decisions before going solar.
Should I still compare installers?
Should I still compare solar installers? Yes. Solar Plus does not recommend or sell installer packages, but it is still important to review different solar providers if you plan to install a system. Compare their experience, warranties, equipment brands, project scope, after-sales support, and customer reviews before making a decision.
Are the savings guaranteed?
No. Savings depend on actual usage, tariff, system size, weather, shade, and approval conditions.
What should I prepare?
What should I prepare before learning about solar? Start with your monthly electricity bill, property type, roof condition, available roof space, meter phase, and location. These details can help you better understand solar system sizing, estimated savings, and whether rooftop solar may be suitable for your home or business.
