Ordering Your Solar System

Choose a solar company like for consultation. They will come to your home, assess your energy needs and discuss solar panel costs. Based on this, they will give you a proposal for a solar panel system.

Next, you will need to sign a contract with the solar company. The contract will outline the terms of your agreement. It will also include what you can expect from the solar panel installation.

The installation of solar panels will begin once you sign the contract. This can take a few weeks to a few months, depending on the size of your system.

Design And Engineering

The process of designing and installing solar panels is a critical aspect of solar panel installation. The timeline for this process can vary depending on the size and scope of the project.

The first step is to assess the site where the panels will be installed. This assessment will help to determine the number of panels needed and the best location for them.

The next step is to design the system, which includes making sure that the panels will be able to withstand wind, snow, and other weather conditions. This process takes 1-2 weeks.   


Often, the permitting process for solar panel installation can take anywhere from a few weeks to a few months. The first step is to submit an application to your local planning and zoning department. Once the application is approved, you will need to get a building permit.

The next step is to have the solar panel system inspected by the local building inspector. Finally, you will need to get a certificate of occupancy from the local zoning department.

Scheduling The Solar Panel Installation

Installing solar panels takes 1-2 days to complete. Installation days start early, around 7 am, and end around 5 pm. The solar panel installer will need access to your roof during this time so they can install the panels.

They will also need to be able to disconnect your power source so they can connect the panels to your home’s electrical system.

Solar System A Long-Term Investment

It’s important to know what timeline and cost to expect in the installation process. A typical installation can take anywhere from a few days to a few weeks. The cost will vary depending on the size of your system and your location.

Yet, the investment is worth it, as solar panels can provide significant savings on your energy bills over the long term.
