Solar Panel Maintenance & Servicing

Keep an eye on your solar generation. Normally solar panel systems perform perfectly. The panels sit on your roof or ground, convert sunlight into DC electricity, and then your solar inverter turns the DC electricity into AC electricity to power your home, electric car, and whatever else you have plugged in. Ideally, solar panel maintenance, or overall system repair, should be

Everything you need to know about AC solar panels

The solar panel that is covered by leaves drops energy production to 50% because half of the panel is covered. With a central inverter, the remaining four panels will also operate at 50%. With AC solar panels, only the covered solar panel will operate at 50%; the rest will be operating at 100% because they each have an individual inverter.

A Guide to Solar Inverters: How They Work & How to Choose Them

The first part is the power optimizer, which handles DC to DC and optimizes or conditions the solar panel''s power. There is one power optimizer per solar panel, and they keep the flow of energy equal. For example, with a standard string inverter, if one solar panel produces less energy, all the solar panels in that string will produce less energy.
