*A.1.1. Solar PV*

The power output of the solar system is given by Equation (A1). It is proportional to the incident radiation on the tilted surface *G*(*t*) and is partly influenced by the cell temperature *TC*(*t*). Details regarding the calculation of these parameters can be found in [64]. In Equation (A1), *SPV* is the rated size of the solar PV installation, η*PV* is the derating factor (0.8), *GSTC* is the irradiance at standard test conditions (STC, 1 kW/m2), <sup>α</sup>*<sup>P</sup>* is the temperature coefficient of power (−0.005 K−1), and *TSTC* is the temperature at STC.

$$P\_{PV}(t) = S\_{PV} \eta\_{PV} \frac{G(t)}{G\_{STC}} [1 + \alpha\_P (T\_C(t) - T\_{STC})],\tag{A1}$$
