Solar panels perform optimally when they are free from any shading. Even a small shadow on one panel can significantly reduce the efficiency of the entire solar array. In fact, shading from trees can reduce your solar output by 30-40%, especially during crucial times like early morning and late afternoon when power costs are higher. With spring approaching, now is the perfect time to cut back branches that are affecting your panels’ performance.
Think of your solar panels as a “string”—even a small amount of shade on a single cell can act like a knot, restricting energy flow. The impact of shading can vary depending on the age of your solar panels. In older panels, shading even a single cell can drastically reduce the output of that panel, potentially affecting the performance of the entire string of panels.
TreeWorks can help by trimming branches that block sunlight, particularly as foliage thickens in spring and summer.
Don’t forget that dust and bird droppings can further lower efficiency. Cleaning your panels twice a year can increase their output by up to 5%.
To ensure your solar panels are working at peak performance:
- Trim back branches
- Consider tree placement with future growth in mind
- Clean panels regularly to remove dust and debris
A little maintenance can make a big difference in maximising your solar panel efficiency!
