Standard installation of solar systems usually lasts between 1 to 3 days. However, there can be several factors that can affect the duration of the installation.

One of these factors includes the type and size of the solar panel that will be installed. Naturally, the larger and more complex solar panel takes more time.

In addition, the installation process can also take longer if the property requires an upgrade to fit the solar system requirements. If roofing and electrical system works are involved, the installation can last for a couple of weeks upto a month.

The weather could also be another factor that will affect the duration of the installation.
