What is the formula for calculating the technical solar potential of an office block, and what do the variables H_A, A_pv, η_sys, K, R_1, and R_d represent?
The technical solar potential of an office block is calculated as E_p = H_A × A_pv × η_sys × K × Σ_{i=1}^{N} [1 − R_1 − (N − 1) × R_d]. H_A is the cumulative solar radiation received by the building surface, A_pv is the mountable area of the PV modules, η_sys is the photovoltaic conversion rate of the PV modules (taken as 21.86%), K is the combined efficiency factor (taken as 85%), and R_1 and R_d are the attenuation rates of the PV module in the first year and in subsequent years (1.5% and 0.48%, respectively).
Key points
