In a specified condition, I studied an optimum tilt angle of a grounded solar photovoltaic array that made a electrical energy cost cheapest, before. However, when we decide a system configuration, we have to consider a land cost and shadow of front photovoltaic arrays, and other conditions.
To solve these problems, I studied effects of cost of. sysytem components, a land cost, shadow of front phtovoltaic arrays for the optimum tilt angle and made them clear. And I made sure that the optimum tilt angle decreases according to increase of system production. And when a space between two photovoltaic arrays is fixed, the optimum tilt angle increases to reduce needed land area according to increase of land cost.
I also made sure that the best configuration of photovoltaic array for minimizing the electrical energy cost besides them.
