Check how shadows change throughout the day and across different seasons. Will your solar panels still get enough sun in winter? Will that tree block the afternoon sun from your kitchen window? Or when will your terrace finally be in the shade? Useful for photographers, hikers, home buyers, balcony owners, campers, gardeners, beach lovers, future solar power heroes and vitamin D hunters. One purpose. No account. No ads. No subscription.
