6 FAQs about [The bigger the sun is the higher the power generation of photovoltaic panels]

Why do solar panels need a higher sun intensity?

A higher sun intensity means there is more solar radiation available for the solar panels, resulting in increased electricity production. As a result, maximizing the exposure of solar panels to sunlight is beneficial in improving the overall efficiency of the PV system.

When does a solar PV system generate more watts?

Figure 1 shows PV generation in watts for a solar PV system on 11 July 2020, when it was sunny throughout the day and on 13 July when there was a mixture of sun and cloud. A south facing solar PV system will tend to generate more around noon.

Why is solar PV generation higher in the summer?

Solar PV generation is higher in the summer than the winter due to longer days and the sun being higher in the sky. Figure 4 shows the typical monthly values of solar PV generation for a 2.35kW solar PV system in London which faced 60 degrees from south. From year to year there is variation in the generation for any particular month.

Why do solar panels produce more electricity?

The more sunlight a solar panel can absorb, the more electricity it can produce. When the sun’s intensity is high, solar panels produce more power due to increased photon emission, leading to higher energy production. A solar panel’s efficiency refers to the proportion of sunlight it can convert into usable electrical energy.

Do solar panels produce more energy if it's cloudy?

However, solar panels can still generate electricity in less-than-ideal conditions, like on cloudy or cold days. For example, in sunny states like Arizona or California, solar panels can produce more energy due to longer peak sun hours and higher solar irradiance levels. How do solar panels work when it’s cloudy?

Do solar panels produce more energy if the temperature rises?

While sunny warm days seem to be best for solar energy generation, silicon PV panels can become slightly less efficient as their temperature rises. This is due to a property of the silicon semiconductor, which means that these class of Solar PV panels have a ‘negative coefficient of temperature’: this means they produce less energy when really hot.
