Clean Solar Index

Figure of Merit (FoM)

The FoM determines the optimal cleaning methodology based on 4 customizable parameters.

\[ FoM = \frac{(Recovery)^{\alpha} \times (Lifetime)^{\beta}}{(Water)^{\gamma} \times (CAPEX)^{\delta}} \]

Adjust sliders to change the variable exponents in the formula above.
