How much are photo voltaic panels?

The cost of photovoltaic (PV) panels has come down significantly in recent years, making them more affordable for residential and commercial use. According to the U.S. Department of Energy, the average installed cost of a solar PV system in the United States was $2.77 per watt in 2020, down from $4.34 per watt in 2010. This means that a 1-kilowatt (kW) solar PV system would cost about $2,770 to install, while a 5-kW solar PV system would cost about $13,850.

However, the actual cost of PV panels can vary depending on a number of factors, including the type of panel, the efficiency of the panel, the size of the system, and the installer. Here is a breakdown of some of the factors that can affect the cost of PV panels:

* Type of panel: There are two main types of PV panels: monocrystalline panels and polycrystalline panels. Monocrystalline panels are more efficient than polycrystalline panels, but they are also more expensive.

* Efficiency of the panel: The efficiency of a PV panel is measured by the amount of sunlight it can convert into electricity. The higher the efficiency of the panel, the more electricity it will generate.

* Size of the system: The size of the PV system you need will depend on your electricity usage and the amount of sunlight available at your location. A larger system will generate more electricity, but it will also be more expensive.

* Installer: The installer you choose will also affect the cost of your PV panels. Some installers may charge more for their services than others.

It is important to compare quotes from multiple installers before you make a decision about purchasing PV panels. You should also consider the long-term benefits of going solar, such as reduced electricity bills, increased home value, and environmental benefits.
