How long does it take to install commercial solar panels?

Due Diligence – 1 to 3 months

Evaluation of the facility, legal review of the project, and the basic design of where the solar panel goes are some of the evaluations when you plan on going solar for your commercial building. 

The engineer would go to the facility to verify the measurements and inspect the building during the physical evaluation that usually would take about 1 to 3 weeks.

After the physical evaluation, then the constriction team would then help the owner of the facility get permission from the city to confirm the construction. This legal process would have to be the longest part and would usually take about 2 to 8 weeks.

After getting the go signal, the engineer would then draft a basic plan on where the solar panels fit the best. This process would then usually take about 1 to 3 weeks to draft.

Engineering and commercial solar panel design – 1 week

The engineer would continue the basic design using 3D software to model the new design’s layout and finalize the construction plan in this phase.

Construction and solar panel system commissioning – 2 to 3 weeks

This part of the process would depend on the complexity of the project and outside factors, but usually, the on-site construction phase would take about 2 to 3 weeks. There are some solar companies who would provide you with roof-mounted solar arrays, solar carports, and ground-mounted solar panels and each of these have their own nuances when it comes to how long it takes to install them. If you decide to install all of them, then obviously the whole process would take longer.

Solar panel operations and maintenance

Solar installation companies usually handle the engineering, procurement, and construction of your solar project and the typical payback for solar projects is usually between 3 to 7 years. This would depend on the facility. When it comes to the standard warranty, it would usually last 25 years, ensuring you that your solar products would last long into the future.
