"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.
