As solar power systems are hardwired without moving parts, they require very little maintenance. Nevertheless, the time needed for cleaning and maintenance can vary and it depends on several factors such as the slope of your roof, the location of your building, the presence of particles, etc. At Progressture Solar, we provide operation and maintenance (O&M) services to our clients that include the cleaning and inspection of solar panels on an annual basis. It is our responsibility to keep your panels clean at regular intervals to prevent residue from forming and to ensure their optimal performance.
