Before and After: Our Pressure Washing Results

Solar power systems generate electricity with no moving parts, which means they have simpler maintenance requirements than other power generation systems. For example:

• PV modules do not have spinning blades and gearboxes like wind turbines, nor are they exposed to fossil fuel combustion at high temperatures.
• But since solar panels don’t move, dust and other particles can accumulate more easily on their surface.

If dust build-up blocks 50% of the sunlight reaching your solar panels, their energy output can drop by half. This decrease in productivity can negatively affect electric bill savings — if you were previously saving $100 each month, you might notice that savings drop to around $50 a month.

Regular cleaning helps keep your solar panels operating at optimal capacity, which means your system generates its expected electricity output. A dirty solar energy system does not operate at maximum efficiency, which can result in higher power bills and, as a result, a longer payback period
