Many times we are asked why a walkway is so very important in Rooftop Solar installations and why we put so much impetus in walkway design. As seen in this picture, a good walkway gives access to every panel and makes the cleaning process much easier and safer. As seen here, before cleaning the yield of the plant was 1.3 KW which jumped to 3.2 KW after cleaning . That is an increase of almost 150% in just 10 minutes of cleaning. Without a Walkway , this cleaning would have been very very difficult and also dangerous for personnel involved in cleaning. Also , If panels are kept clean, the chances of hot-spot formation on the solar panels is much lower thereby increasing the life of the panel and also giving better performance.
