Solar Panels in Perth

Do solar panels work in Perth?

Yes. Perth gets good daylight, and modern panels generate from daylight not just sunshine, so they work effectively across the city year-round.

Perth sits at the gateway to the Highlands on the River Tay, and its position gives it good daylight hours for solar generation. Solar PV panels generate electricity from daylight rather than requiring direct sunshine, so they work on overcast days as well as clear ones. Output is highest from April to September, but the system continues generating through winter on bright days. Our survey assesses your roof's orientation, angle and any shading from nearby buildings or trees to estimate how much energy your home could generate. For more on the survey process, see our how it works page.

What roof types are common in Perth?

Perth has a mix of older stone buildings, period villas and modern housing developments. Each roof type needs different mounting, assessed during survey.

Perth's housing stock reflects its history as a market town and its modern growth. The city centre and older areas like Kinnoull and Bridgend have traditional stone buildings and period villas with slate roofs. Areas like Letham and Muirton have a mix of post-war and newer housing. Modern developments on the outskirts, such as Scone and Perth West, have contemporary construction with standard tiled roofs. Each roof type requires a different mounting approach — slate roofs on older buildings need careful fixing, while modern tiled roofs are more straightforward. Our survey identifies your roof type and recommends the appropriate system.

Does Perth's location affect solar performance?

Perth sits at the gateway to the Highlands, with good daylight but cooler temperatures. Panels actually perform more efficiently in cooler conditions.

One advantage of Perth's location is that solar panels operate more efficiently at lower temperatures. While it might seem like hotter, sunnier climates would be better for solar, panels can lose efficiency when they get too hot. Perth's cooler climate means that on bright, cool days — common in spring and autumn — your panels can generate efficiently. Combined with the long summer daylight hours of its northerly location, Perth is a good location for solar. A battery can help you make the most of this by storing surplus generation for use in the evening.

Which direction should my Perth roof face?

South is ideal, but east- and west-facing roofs in Perth also generate useful electricity. Our survey checks your roof's orientation and angle.

A south-facing roof gives the highest overall output, but many Perth homes have east- or west-facing roofs that also perform well. East-facing roofs generate electricity in the morning, while west-facing roofs generate in the afternoon and evening. Both orientations can produce a useful amount of electricity across the year. Adding a battery lets you store surplus generation from any direction for use whenever you need it. Our survey measures your roof's exact orientation, pitch and shading to advise on the best setup.
