According to Solar Panels Plus, a manufacturer of solar-powered air conditioning products, these types of units require very little maintenance. The units run on simple components, and some actually have no moving parts requiring electrical repair.
There are several varieties of solar air conditioners available, including options sold by Atlantis Solar, that simplify maintenance by allowing for easy addition, removal and repair of features. Kingtec Solar, another solar air conditioner manufacturer, uses components that are proven efficient and require little maintenance. Its products have all of the solar components built into the DC unit, and Kingtec states that its air conditioners are long-lasting and continually efficient even in extreme conditions.
