Reading E-Gauges and the math of solar cleanings

To understand the value of a solar panel staying cleaned, we were schooled on how to read E-gauges on a solar system. The e-gauge tells you the amount of power a solar system is producing. From the work we did with the information gathered from reading these e-gauges we came up with some average numbers of the boost in efficiency systems have after being cleaned. We found that a system gains up 3.5% of production when cleaned at twelve months. At eighteen months systems can gain over 9.5% efficiency.
