"How many panels can fit on my roof?" The answer depends on your property type and roof layout.

Double-Storey Terrace (Intermediate)

  • Roof Space: ~300 - 450 sqft
  • Max System Size: about 6.20 kWp to 8.06 kWp (10 to 13 panels of 620 W, as in our layout guide)
  • Typical Monthly Saving: about RM 180 - RM 280 / month (layout guide estimate; it depends on your bill)
  • Recommendation: Use high-efficiency panels (575W+) to maximize limited space.

Semi-Detached / Corner Lot

  • Roof Space: ~600 - 900 sqft
  • Max System Size: 8 kWp to 12 kWp
  • Typical Bill Offset: about RM 400 - RM 600 / month
  • Recommendation: Ideal for 3-phase systems. Good ROI.

Bungalow

  • Roof Space: >1200 sqft
  • Max System Size: Inverter up to 15 kWac for three-phase domestic (Solar ATAP cap). Larger systems require a TNB CCC review.
  • Recommendation: Consider aesthetic "All-Black" panels as the roof is often visible from the ground.
