How much does a 3kWp solar panel system cost in Penang in 2026?

A 3kWp rooftop solar system costs RM 12,000-18,000 fully installed in Penang in 2026, including panels, inverter, mounting, wiring, and the TNB NEM application. At current electricity tariffs, this system saves RM 120-165 per month and achieves a simple payback of 8-10 years.

How does NEM (Net Energy Metering) work in Penang?

Under NEM 3.0, surplus solar energy exported to the TNB grid is offset against your consumption at a 1:1 ratio. One exported kWh cancels one imported kWh on your bill. Any remaining export goes into rollover credit for 24 months. NEM does not pay cash for excess generation.

What is the payback period for solar panels in Penang?

Residential solar systems in Penang achieve a simple payback of 7-10 years depending on system size and electricity consumption. Penang's average of 4.5-5.0 peak sun hours per day gives above-average generation yield. Solar prices have fallen roughly 30% since 2020, improving the economics significantly.

Can a condo unit in Penang install solar panels?

Condo solar installations require management corporation (MC) approval and roof access rights, which most MCs do not grant to individual units. Landed properties (terrace, semi-D, bungalow) face no ownership barriers. Some strata developments are pursuing communal solar as a building-wide project under the Strata Management Act.
