Custom-designed residential solar solutions for Malaysian homes, covering system sizing, Solar ATAP application, installation, monitoring and optional battery storage.
Facing rising electricity bills, increasing tariffs, and long-term dependence on the power grid at home?
Residential solar PV systems installed on rooftops convert sunlight into electricity. In Malaysia, a household home solar system enables homeowners to generate clean energy, reduce reliance on the grid, and lower monthly electricity costs.
Proper solar panel installation ensures each system is tailored to household energy requirements while maximising available roof space, delivering a reliable, efficient, and sustainable power solution for modern homes.
Under the Self-Consumption (SELCO) scheme, homeowners use the electricity generated by their solar panels for house use directly to power their household. Any surplus energy can be stored in battery systems, helping to maximise savings and reduce reliance on conventional grid electricity.
Solar panels for houses use photovoltaic (PV) technology to convert sunlight into electricity. A typical home solar power system consists of rooftop solar panels, a solar inverter, mounting structures, electrical protection equipment and monitoring components.
The solar panels generate direct current (DC), which the inverter converts into alternating current (AC) for household appliances.
The system’s size and design depend on the property’s electricity consumption, available roof space, shading and electrical requirements.
RayGoSolar provides residential solar system assessments and installations tailored to different property types and energy needs.
Solar panels can be installed on many types of landed residential properties in Malaysia, including terrace houses, semi-detached homes and bungalows.
However, the roof must be suitable for installation. Factors such as structural condition, roof material, shading, available area and electrical infrastructure should be assessed.
Homeowners can arrange a professional roof assessment to determine the appropriate home solar power system for their property.
Choosing the right home solar power system involves assessing household electricity consumption, available roof space and the property’s electrical connection.
Residential solar systems are commonly measured in kilowatt-peak (kWp), which represents the rated capacity of the installed solar panels under standard test conditions.
| Solar System Capacity | General Consideration |
|---|---|
| 3–4 kWp | Smaller residential electricity requirements |
| 5–6 kWp | Moderate household electricity consumption |
| 7–10 kWp | Higher household electricity demand |
| Above 10 kWp | Requires assessment of supply configuration, relevant programme limits and technical requirements |
These ranges are illustrative and do not represent fixed recommendations. The suitable system size depends on your electricity bills, roof conditions, solar programme requirements and expected daytime consumption.

Solar Energy
Battery Energy Storage System (BESS)
SELCO, or Self-Consumption, is a solar energy approach where electricity generated by a residential solar system is used directly to power household appliances.
The right solar system size depends on your electricity consumption, roof space, daytime energy usage and future energy needs. A larger system is not always better; the goal is to design a system that matches how your household actually uses electricity.
A recent TNB bill is one of the best starting points because it shows your monthly electricity consumption in kWh. Ray Go Solar can use this together with your roof layout, shading conditions and available installation area to estimate a suitable system size.
Homes with higher daytime electricity usage may be able to use more solar power directly, while households that consume more electricity at night may benefit from adding battery storage.
For a more accurate assessment, review several months of electricity usage rather than relying on a single bill. You can also refer to our guide on how to read your TNB electricity bill for solar before requesting a system assessment.
The cost of a solar panel system in Malaysia depends on several factors, including system size, roof condition, energy usage, equipment quality, and installation complexity. Residential solar solutions are typically customised to meet household needs, and pricing can also be influenced by available solar programmes and system configuration.
A professional site assessment is the best way to determine the most suitable system and overall investment for your home.
A roof is generally suitable for roof solar panels if it has enough available space, receives good sunlight exposure, and is structurally sound. Factors such as roof orientation, shading, and material also affect system performance.
The number of solar panels depends on each panel’s rated wattage, household electricity consumption, roof space and the intended system capacity. A professional solar assessment can determine a suitable configuration.
Solar panels generate electricity from sunlight. A complete home solar power system also includes components such as an inverter, mounting structures, electrical protection and monitoring equipment.
Solar panels can supply a substantial portion of a household’s electricity needs when generation is available. However, the actual contribution depends on system capacity and consumption. Grid electricity or suitable battery storage may still be required.
