Can I object to a neighbour's planning application on solar grounds?

You can submit a comment, but planning authorities rarely refuse applications based on solar panel shading. The neighbour's right to extend their property generally takes precedence.

What about the Prescription Act?

The Prescription Act 1832 establishes a 'right to light' for windows after 20 years of unobstructed light. Courts have NOT extended this to solar panels. Solar-specific legislation may come in the future but doesn't exist yet.

Are there any protections?

Very limited — if you can prove a neighbour's SOLE PURPOSE in building was to spite you and block your solar (malicious intent), you might have a case. In practice: extremely difficult to prove and rarely successful.

Do I have a right to sunlight for solar panels?

There is NO specific 'right to solar light' in UK law: (1) PRESCRIPTIVE RIGHT TO LIGHT exists for windows (after 20 years of unobstructed light) but does NOT extend to solar panels. (2) A neighbour CAN build an extension, plant trees, or erect a fence that shades your panels — with no legal liability. (3) You CANNOT force a neighbour to remove or trim anything that shades your solar installation. (4) PLANNING objections on grounds of solar shading are generally not upheld — councils consider the neighbour's right to develop their property. WHAT YOU CAN DO: (1) Install micro-inverters or optimisers to minimise shade impact. (2) Talk to your neighbour BEFORE installing — good relationships prevent future conflicts. (3) Position panels to avoid likely shade sources. (4) Consider south-facing positions away from boundary lines.
