You’ve heard the same doubt repeated: “Solar is fine in summer, but winter? Short days, low sun.. will the panels actually produce anything worthwhile when heating costs are highest?” That uncertainty keeps many homeowners stuck paying full grid prices year-round, convinced winter will always be the weak link. Fiona in Cottesloe was openly sceptical when she signed up earlier this year. Now her monitoring app shows her 8.8 kW system averaging 21 kWh daily through June - more than enough to run her reverse-cycle and charge the battery for evenings. This June, data from hundreds of Sure Renewables systems confirms modern arrays produce 18–25 kWh on clear winter days. Cooler temperatures boost efficiency, and optimised angles capture low sun far better than older myths suggest. The evidence is no longer theoretical - it’s live data from roofs just like yours. How much longer will outdated winter myths keep you paying premium prices for power the sun is still delivering?
