You have solar panels – now what?

⚡ Solar panel efficiency measures how good a panel is at turning sunlight into electricity

🏡 Domestic solar panels are typically 18-24% efficient

📈 Solar cells are much more efficient than solar panels

🏆 The most efficient type of solar panels are perovskite

🌞 Bifacial solar panels are more efficient than standard solar panels

What does ‘solar panel efficiency’ mean?

People think that you need perfectly sunny weather to make solar panels worthwhile, but this isn’t the case - all solar panels need in order to generate electricity is daylight, not sunlight. There are many other factors beyond location that have an impact on generation, including roof size, pitch, orientation and shading.
