How Long Does It Take To Complete A Solar Project

April 20, 2023

Solar projects can take anywhere from six months to three years or more to go live

The timeline for solar projects from decision to activation can vary depending on various factors such as project size, location, permitting process, financing, equipment availability, and construction timeline. However, a general timeline can be broken down into the following stages:

  1. Feasibility study and site selection: This stage involves conducting a feasibility study to determine the potential of the site for a solar project. This can take a few weeks to several months, depending on the complexity of the project.

  2. Permitting and interconnection: This stage involves obtaining the necessary permits and approvals from local and state authorities, as well as securing interconnection agreements with the utility company. This process can take several months to a year.

  3. Financing: This stage involves securing financing for the project, which can include debt, equity, tax credits, and other financial incentives. This process can take several months to a year.

  4. Equipment procurement and construction: This stage involves procuring the solar panels, inverters, and other equipment necessary for the project, as well as constructing the solar arrays and connecting them to the grid. This process can take several months to a year, depending on the size of the project.

  5. Testing and commissioning: This stage involves testing the solar arrays and ensuring they are operating as intended. This can take a few weeks to a few months.

  6. Activation: Once the solar arrays are tested and approved, they can be activated and start generating electricity. This typically occurs within a few days of testing and commissioning.


Overall, the timeline for solar projects from decision to activation can range from 1 to 3 years or more, depending on the factors mentioned above.
