For the photovoltaic cells with constant resistance load, the output voltage, current, and output power of the photovoltaic cells decrease obviously with the increase of the temperature of the photovoltaic cells, and the photoelectric conversion rate of the photovoltaic cells shows a linear downward trend.
If you know the number of PV cells in a solar panel, you can, by using 0.58V per PV cell voltage, calculate the total solar panel output voltage for a 36-cell panel, for example. You only need to sum up all the voltages of the individual photovoltaic cells (since they are wired in series, instead of wires in parallel).

Temperature inhomogeneity occurs frequently in the application of photovoltaic devices. In the present study, the effect of nonuniform horizontal temperature distributions on the photovoltaic output parameters of a monocrystalline silicon solar cell including short-circuit current, open-circuit voltage, output power, etc. was investigated.
Effect of temperature on PV output power. The current–voltage and power voltage characteristics of a mono crystalline silicon cell for constant light intensity have been studied experimentally by Chander et al. .

As shown in Fig. 2, SCs are defined as a component that directly converts photon energy into direct current (DC) through the principle of PV effect.Photons with energy exceeding the band gap of the cell material are absorbed, causing charge carriers to be excited, thereby generating current and voltage [].The effects of temperature on the microscopic …
The output voltage of a PV cell is affected only slightly by the amount of light intensity (irradiance), but the current, and thus the power, decreases as the irradiance decreases. ... Typical efficiencies range from 14% to 18% for a monocrystalline silicon PV cell. Some manufacturers claim efficiencies greater than 18%. Factors That Effect ...

When a photon hits a piece of semiconductor, one of three things can happen: 1. The photon can pass straight through the semiconductor — this (generally) happens for lower energy photons.2. The photon can reflect off the surface.3. The photon can be absorbed by the semiconductor if the photon energy is higher than the band gap value. This generates an electron-hole pair and some…
