Consequently, the capacity factor of the solar energy system here is much lower than that of Phoenix at about 16%. As we have seen, the capacity factor varies quite a bit for solar photovoltaic systems depending on the location. Generally, it is in the range of 10-25%. One of the key reasons for this low ratio is the nature of renewable power.

Solar explained Photovoltaics and electricity

PV panels vary in size and in the amount of electricity they can produce. Electricity-generating capacity for PV panels increases with the number of cells in the panel or in the surface area of the panel. PV panels can be connected in groups to form a PV array. A PV array can be composed of as few as two PV panels to hundreds of PV panels. The

6 FAQs about [Reasons for low photovoltaic panel production capacity]

Why are my solar panels not producing enough energy?

Solar panels are a great way to generate clean, renewable energy. However, you may sometimes notice that your solar panel system isn't producing the expected amount of energy. It is important to check for any visible issues, such as shading or dirt on the panels.

How efficient are solar panels?

Efficiency of solar panels represents how much of sunlight that hits a solar cell gets transformed into electricity. Some of the first solar panels had efficiencies between 8 to 10 percent. Other traditional sources of energy had efficiency of 40 to 55 percent with the combined cycle generators . The competition was just unbalanced.
