The rest on the parameters are: L: expense on the constructing license compared to the cost of the EPC.

The are les model. that deviation increases in calculated for the calculated values mean relative error in the 120 cases is 0.44 . Nevertheless, the precision has been verified for exactly the same place, so this outcome will not enable us to verify its precision in other locations within the exact same variety. Even so, it is actually critical to keep in mind that the outcome depends on the International Horizontal Irradiation introduced in to the equation and may be the primary climatological variable. Plant CAPEX To confirm the accuracy from the plant’s calculation methodology, the cost of each and every in the facilities has been recalculated primarily based on the desired energy. In this case, the precision with the variable element is compared around the one particular hand (that’s, devoid of contemplating the costs of modules, inverters, and structures) and alternatively, the final result, to find out the precision with the component whose cost is obtained from the regression and see how it impacts getting into the proposed values for the main equipment.
