How to Handle Defective Solar Panels | Energy Central

Before looking into any of the internal anatomy of a defective solar panel, it''s important to consider that the problem may lie with the positioning and the angle of the panels themselves. When angled correctly, solar panels can only convert about 20% of the sun''s energy into electricity, and that number can plummet when the panels aren''t angled properly.
