Of the top 10 postcodes in the state for the uptake of solar energy, five are in the northern rivers, according to information released by the Nature Conservation Council of NSW.
Second from the top was postcode 2477 (Alstonville, Rous and Meerschaum Vale) with 21 per cent solar powered, closely followed by postcode 2486 (Banora Point, Tweed Heads South and Bilambil) with 20 per cent.
Other solar hotspots were 2484 (Murwillumbah) on 18.4 per cent, 2478 (Ballina and Lennox Head) on 17.3 per cent and 2483 (Brunswick Heads, Ocean Shores and Billinudgel) notching up 16.6 per cent.
The top spot in the state was 2830 (Dubbo and surrounds), which has a remarkable 28 per cent of its energy needs supplied by solar power.
Also on the list were 2880 (Broken Hill and Silverton) 19.4 per cent, 2550 (Bega region) 16.6 per cent, and the only Sydney suburb, 2147 (Seven Hills and Lalor Park) 18.2 per cent.
Despite its ostensibly clean, green credentials, Byron Bay was nowhere on the list.
