A smarter solar plan, sized for your home

Yes. A properly designed solar system can reduce your monthly electricity costs and lower your exposure to future tariff increases. The actual savings depend on your electricity usage, daytime consumption, roof condition, system size and the applicable tariff or energy offset mechanism.

Solar can significantly reduce your electricity bill, but it may not eliminate it completely. You may still use electricity from the grid at night or when solar generation is low, and TNB charges, taxes or other applicable fees may remain.

The right system depends on your recent TNB bills, daytime and night-time electricity usage, roof size and orientation, electricity supply type, and future needs such as EV charging or battery storage. JS Solar will assess these factors before recommending a suitable system.

Yes. Solar can help offset the electricity used to charge an electric vehicle, especially when the vehicle is charged during solar-generating hours. Actual savings depend on the charging schedule, vehicle usage and system capacity.

Yes. Solar panels can still generate electricity from available daylight, although output may be lower than on a clear, sunny day.

Solar ATAP, or the Solar Accelerated Transition Action Programme, is Malaysia's rooftop solar programme for eligible consumers in Peninsular Malaysia. It allows solar electricity to be used at the premises, while surplus energy may be exported to the grid under the applicable energy offset mechanism.

Solar ATAP is open to existing TNB consumers in Peninsular Malaysia who meet the programme and technical requirements. An applicant cannot remain registered under NEM, SelCo or another solar PV programme; where permitted, the existing contract must be terminated before joining Solar ATAP. Accounts that are also generators, including co-generation or back-feed accounts, and multi-tenant consumer accounts are not eligible. The installation must be located at the same premises, and certain system capacities require a TNB technical assessment. An appointed SEDA-registered PV service provider will confirm your eligibility and submit the application through the eATAP system.

Both programmes prioritise using solar energy at the premises and allow surplus electricity to be exported to the grid. Under NEM Rakyat 3.0, each exported kWh offset one imported kWh on a one-to-one basis, and unused energy credit could roll forward within the applicable settlement period for up to 12 months. Under Solar ATAP, a domestic consumer's exported energy is credited at the applicable Energy Charge, only up to the electricity imported within the same billing period. Unused export credit is not carried forward to the next bill and cannot offset the Automatic Fuel Adjustment (AFA). Solar ATAP operates for up to 10 years; after that, the system may continue for self-consumption without export offset or roll-over. This makes accurate system sizing and strong daytime self-consumption especially important.

The Solar ATAP contract runs for 10 years from its commencement date. After that period, the system may continue operating for self-consumption, but excess energy exported to the grid will no longer receive an offset or roll-over under Solar ATAP.

For domestic consumers, systems up to 5 kW on single-phase supply and up to 15 kW on three-phase supply follow the standard capacity thresholds. A larger system may require a TNB Connection Confirmation Check and approval. The final capacity is subject to roof space, electricity demand, system design and technical approval.

Solar electricity is used at your premises first. Any surplus may be exported to the grid and credited according to the applicable Solar ATAP energy offset mechanism and tariff rules.

No. You can install a grid-connected solar system without a battery. A battery is optional and may be added if you want to store more solar energy for later use or provide backup power for selected appliances, subject to system design.

A standard grid-connected solar system automatically shuts down during an outage for safety. A properly designed hybrid solar system with battery backup can continue supplying selected essential appliances, depending on the battery capacity and backup configuration.

It depends on your priorities. A standard grid-connected system is suitable for reducing electricity costs. A hybrid system offers added flexibility through battery storage and potential backup power, but it usually requires a higher investment.

In many cases, yes. However, future compatibility depends on the inverter, electrical design, available space and battery specifications. If battery storage may be part of your future plan, tell our team during the initial consultation so the system can be designed accordingly.

SuRIA Home is a government-supported incentive for eligible Malaysian domestic consumers who install solar under Solar ATAP. It provides a one-time cash rebate to help reduce the initial cost of adopting rooftop solar.

Eligible applicants may receive RM600 per kWac, up to a maximum rebate of RM3,000, subject to the programme's terms, available allocation and successful commissioning requirements.

The rebate is intended for eligible Malaysian citizens registered as domestic TNB consumers under Solar ATAP who meet the programme conditions. Applicants who previously received a cash rebate under the SolaRIS programme are not eligible. Approval remains subject to the latest programme terms and available allocation.

Common documents may include the registered consumer's identification, latest TNB bill, property and system details, technical drawings, application forms and supporting declarations. Additional documents may be required depending on the installation. JS Solar will guide you through the documentation process.

It may be possible, depending on roof ownership, access, the building's electrical arrangement and approval from the Joint Management Body or Management Corporation. At present, JS Solar's residential service is focused mainly on landed properties.

Not every home needs an upgrade. It depends on your electricity demand, proposed solar capacity and future loads such as multiple air-conditioners, EV charging or battery storage. Our team can assess whether an upgrade is necessary.

Yes. JS Solar provides end-to-end support covering consultation, site assessment, system design, regulatory submissions, procurement, installation, testing, commissioning and after-sales support.
