General Solar
A solar system works by converting sunlight into usable electricity. Solar panels capture sunlight and generate direct current (DC) electricity. An inverter then converts the DC electricity into alternating current (AC) electricity, which powers household appliances and electrical devices. This process provides clean, renewable energy for homes and businesses.
A Battery Energy Storage System (BESS) helps maximize solar savings by storing excess energy for use at night, reducing electricity bills by up to 98%. It can deliver strong long-term returns, increase energy independence from utility tariff and provide backup power during blackouts to keep essential appliances running.
If your home is under renovation, our consultants can estimate your future electricity usage based on factors such as air conditioning, appliances, and household needs. We also recommend installing the solar system during renovation, as this allows for cleaner cable routing and avoids visible casings that may affect your interior design.
Monitoring your system is super straightforward. Our project engineer will personally sit down with you to help download and set up the Solis Cloud app right on your smartphone. You can monitor your usage and generation daily, monthly and even yearly.
Yes. If installing the solar system & battery system, it is is fully capable of supplying power to all of your critical home appliances such as fan, lighting, refrigerator and etc.
Yes, your solar panels will still generate electricity. However, because their performance depends directly on sun irradiance (sunlight intensity), the energy output will be lower compared to a clear, sunny day.
You do not need to worry about solar panels attracting lightning during thunderstorm, as there is no evidence or source showing they do. To keep your home completely safe, our systems come equipped with comprehensive lightning and surge protection. We use grounded mounting brackets with an earth cable connected directly to them so any rare high-voltage strike is safely discharged straight into the ground. On top of that, advanced inverter features like AFCI protection proactively catch arc faults to reduce fire risks, a smart alarm system instantly flags temperature or voltage errors, a surge protective device (SPD) automatically shuts down the inverter during power spikes, and a dedicated earth cable keeps stray currents completely away from your equipment.
Solar Accelerated Transition Programme (ATAP)
The ATAP solar program allows homeowners to generate electricity from solar panels. Without a battery, excess solar energy is exported to the TNB grid and offset against electricity usage. With a battery energy storage system (BESS), excess energy is stored for nighttime use, reducing grid reliance and providing backup power during outages for essential appliances.
The payment terms are structured in three stages: a 10% deposit upon document collection and Solar ATAP application, a 70% progress payment after Solar ATAP approval and before installation begins, and the remaining 20% final payment upon successful completion of the solar system installation
Solar ATAP applications have a high approval success rate when the TNB account holder has no outstanding penalty debts or blacklist issues. If any penalty debt exists, approval is typically granted once the balance is cleared. All required documents are carefully verified before submission to maximize approval success.
Yes, our dedicated Admin and Customer Service team manages the entire Solar ATAP and TNB application process. With a 99.99% approval success rate, we help ensure a smooth and hassle-free experience from submission to approval.
Yes! Domestic customers who install residential rooftop solar PV systems under the Solar ATAP (Accelerated Transition Action Programme) scheme are eligible for a cash rebate of RM600 per 1 kWac, up to a maximum of RM3,000 under the latest Sustainable Rebate and Incentive Assistance (SuRIA) Home initiative. This initiative is only allocated on a first-come, first-served basis for Solar ATAP installations commissioned by 31 December 2026, or until the RM150 million allocation is fully utilised, whicever comes first.
Commercial & Industrial
Most C&I clients in Malaysia can reduce 20%–50% of their monthly TNB electricity bill, depending on roof size and operating hours.
Factories with daytime-heavy usage typically achieve the highest savings.
The investment cost depends on system size, roof condition, and electricity consumption.
Most C&I solar projects in Malaysia are designed based on ROI instead of fixed price, with typical payback around 3–5 years.
We provide a detailed proposal showing system cost breakdown, estimated savings, payback period and tax incentive impact (CA & GITA).
Yes, businesses here can tap into some great financial perks that significantly improve project returns and cut down your overall investment costs. You may be eligible for the Capital Allowance (CA) to claim tax deductions on your solar investment, as well as the Green Investment Tax Allowance (GITA) which offers dedicated tax incentives for approved green technology initiatives.
No. Solar installation is planned to be non-disruptive to daily operations.
Work is typically scheduled in phases to ensure minimal or zero impact on production activities.
While solar works wonders for many industrial sites, it is most ideal for businesses that experience high electricity consumption during the day, have large warehouse or roof spaces to work with, and operate on stable, long-term sites. Because every building is built a bit differently and every business operation is not the same. We offers a complimentary proper site assessment first to confirm feasibility and get the system design optimized for your facility.
Operation & Maintenance
Yes, regular solar system maintenance is recommended every two years to ensure optimal performance and longevity. The service typically includes solar panel cleaning and inspection, electrical system checks, mounting structure verification, and a performance analysis report. Scheduled maintenance helps maximize energy production and identify potential issues early.
Product & Services
We provide lifetime after-sales support to ensure your solar system continues to operate smoothly. All support requests receive a response within 24 hours in working day, and if required, a prompt on-site inspection will be arranged. Our local team in JB is available to deliver fast and reliable assistance.
Yes, we provide a free site visit within Johor and Melaka to assess your property's suitability for solar installation. The visit includes a roof inspection, shadow analysis, wiring route planning, TNB meter assessment, a customized solar proposal review, and a dedicated Q&A session to answer your questions and recommend the best solution for your home.
We exclusively use Tier-1 solar panels and Solis inverters, one of the world's leading inverter brands. This combination delivers high performance, long-term reliability, and strong warranty protection for your solar investment.
Yes, local Professional Engineers (PEs) oversee key stages of the project, including design reviews, compliance checks, and commissioning. This ensures your solar system meets safety standards and regulatory requirements.
Every project includes comprehensive engineering assessments, such as single-line diagrams (SLD), structural evaluations, system layouts, and solar performance simulations. These studies help optimize system safety, efficiency, and long-term performance.
For inverters, we use a single, highly efficient Solis string inverter to handle your entire system. Solis is a publicly listed brand that has been trusted since 2005. Our solar system's performance monitoring can also be done in the Solis Cloud Apps. Our project engineer will guide you on how to use the app on the solar system activation day.
