With the nesting season fast approaching and birds already building nests I was wondering if anybody had experienced or found birds nesting beneath solar panels. House Sparrows, Starlings favour the under tile edge type site and whilst under PVs would be on tile, some birds might not be that bothered,seeing the brackets, rails and cables as very suitable nest site possibilities. Could be a nuisance as problem I see is one of impeding air flow and panels possibly overheating and loosing efficiency.
