Calculating your solar potential...
Your Estimated Solar Savings
Your estimated system size exceeds the standard limit for your meter type. A site assessment by a certified installer is recommended.

These figures are estimates based on average Malaysian electricity tariffs and standard market data. Actual savings, system costs, and payback periods will vary depending on your roof condition, panel brand, inverter quality, and installer pricing. Use this as a starting point for your own research.
How the savings estimate works.
System output
Panels, inverter, roof angle, orientation, shade, and weather affect generation.
Programme limits
Solar ATAP capacity and approval details should be checked against current requirements.
Why Your Final Solar Savings May Differ
Daytime usage
Using electricity while solar is generated can affect how much value the system returns.
Shade and roof space
Trees, nearby buildings, roof shape, and equipment placement can reduce usable capacity.
Equipment scope
Panel, inverter, monitoring, warranty, and workmanship should be compared carefully.
Approval conditions
Final capacity depends on technical review and current programme rules.
