How many solar panels do I need?
The number of solar panels you need depends on your average energy use, roof space and budget. A typical home might need 6–8kW of solar, which could mean 15–20 panels. An installer will assess your power bills and site conditions to recommend the right system size. Going too small limits your savings, while going too big may stretch your return on investment.
Do solar panels work during cloudy weather?
Yes, solar panels still generate power when it’s overcast—just at reduced efficiency. Most systems will produce 10–25% of their normal output on cloudy days, depending on panel quality and light conditions. Over the course of a year, this has a minor impact on performance.
A well-designed system accounts for weather variation to ensure strong annual output.
Is solar still worth it with feed-in tariffs dropping?
Yes. While feed-in tariffs have decreased, the value now lies in using your own power rather than selling it back. This is called “self-consumption” and it maximises your savings.
You can further increase benefits by adding battery storage or scheduling energy-heavy tasks (like laundry or dishwashing) during peak sun hours.
