Commercial Solar Panels Installation

How long it takes to install solar panels on a factory or other industrial building will depend on the size of the system and other factors.

For smaller installations consisting of 20 or so solar panels being installed on a small business, the installation could take place in a single day, similar to domestic solar systems.

However, for larger businesses or factories the process might take weeks or even months to design and install. This is particularly true if a factory is located in an area where planning permission is required in proximity to airports or helipads.
