There are many PV installations that are capable of operating for many years with little or hardly any maintenance efforts after their setup. But the challenge lies in managing the existing solar array design, which consists of interactions between series-wired panels. Since each panel’s output and voltage must closely match with the immediate panel next to it, in spite of excellent panel orientation and shading, smaller things like dirt or panel variation can become serious limitations in continuous power generation.
There are systems for Parallel Solar that can overcome these limitations. They have efficient modules that enable each panel to output a constant voltage under all operating conditions, so that all panels become independent contributors to the array’s power bus.
