Solar panel defects: Hot spots, snail trails, and more

Hot spots, one of the most common issues with solar systems, occur when areas on a solar panel become overloaded and reach high temperatures relative to the rest of the panel. When current flows through solar cells, any resistance within the cells converts this current into heat losses.

Cleaning Solar Panels: Why, When, and How You Should Do It

Trees situated near your panels will not only drop their leaves and branches but attract birds as well. These cause bird droppings and debris over time, which will not only require cleaning and clearing but pose a safety hazard. Solar panel cleaning will require a clean sponge and mild detergent to remove grime effectively. If cleaning your

Solar Panel (PV & Hot Water Service), Repair & Maintenance

The easiest way is to count the number of panels. Generally, domestic solar thermal systems tend to have 1-4 panels and solar PV tend to have 6-20 panels. Also, it''s worthwhile searching the web for images of each type of panel (i.e solar heating panel & solar PV panel) and comparing it to what''s on your roof.

Solar Panel Spacing Gaps (Why They Are Important)

Solar panel frames are constantly contracting and expanding, so the panels could possibly touch each other and cause damage if they are too close together. This is one of the reasons why you should never place your solar panels too close to one another.
