Sıcaklık farkları: $\Delta T_{\text{cold}} = T_{\text{min}} - 25^\circ\text{C}$ ve $\Delta T_{\text{hot}} = T_{\text{max}} - 25^\circ\text{C}$

• Soğukta Voc: $V_{\text{oc,cold}} = V_{\text{oc}} \cdot [1 + (\beta / 100) \cdot \Delta T_{\text{cold}}]$
• Sıcakta Vmp: $V_{\text{mp,hot}} = V_{\text{mp}} \cdot [1 + (\gamma / 100) \cdot \Delta T_{\text{hot}}]$
• Maksimum Panel (N_max): $N_{\text{max}} = \lfloor V_{\text{inv,max}} / V_{\text{oc,cold}} \rfloor$
• Minimum Panel (N_min): $N_{\text{min}} = \lceil V_{\text{mppt,min}} / V_{\text{mp,hot}} \rceil$
