6 FAQs about [Pay attention to the photovoltaic panels below]

How does a photovoltaic panel work?

The intensity of current generated by a photovoltaic panel varies with the level of sunlight. The ideal intensity, equivalent to the Vmp, represents the optimal value for achieving the best energy yield. MPPT devices automatically determine this optimal intensity, maximizing the panel’s efficiency and power generation.

Do photovoltaic solar panels produce more energy in winter?

On average, photovoltaic solar panels still produce up to 80 percent more energy during the summer months than in winter. The main reasons are (as you may have guessed) shorter periods of sunlight per day and more days with heavy clouds in winter.

What are the disadvantages of a photovoltaic cell?

Unfortunately, the production of this kind of photovoltaic cell has some disadvantages: the toxicity of cadmium and the low yield that can be obtained. Furthermore, if the photovoltaic panel catches fire and reaches very high temperatures, there is a risk of cadmium being released into the air.

How are crystalline photovoltaic panels made?

Crystalline photovoltaic panels are made by gluing several solar cells (typically 1.5 W each) onto a plate, as can be seen in Figure 1, and connecting them in series and parallel until voltages of 12 V, 24 V or higher are obtained. They are capable of delivering powers of even several hundred watts. Figure 1: A monocrystalline photovoltaic panel.

How does photovoltaic effect affect a potential difference?

When the photons forming the light invest a PN junction — more specifically the surface of the trivalent doping region (P) — they determine a potential difference due to the photovoltaic effect, since each photon that invests a dopant atom frees an electron, which comes out of its bond and becomes available for conduction.

What happens if a panel voltage exceeds a maximum voltage?

When connecting the panel to an inverter or other equipment, it is crucial to ensure that the cumulative Voc resulting from the sum of the individual panel Voc values remains lower than the maximum voltage allowed by those devices. Exceeding this limit can lead to equipment damage or, in severe cases, fire hazards.
