Engineering firms typically want to do a comprehensive site analysis and feasibility study as it provides the client a very detailed deliverable for the client to work from. For larger commercial systems a complete site analysis and feasibility study are absolutely crucial however this complete analysis is an investment and if you are confident that you are moving ahead with your project this can be the perfect place to start. However, not everyone is in that position and for this situation the preliminary assessment study is a perfect option for those clients that aren’t quite ready to commit to something formal, expensive and very detailed and are satisfied with a very rough, quick, inexpensive estimate.
A preliminary assessment study can be completed in a short amount of time, and a significantly less expensive investment and delivers a report that provides a basic and general analysis of your site to determine how much solar you can fit on your site and a ballpark idea of how much it’s going to cost. Those numbers can be taken to management or the board to decide if a grid tie project is a path you’d like to proceed down or if you’d be better off investing in other energy efficient products first. Having a Preliminary Assessment Study to work from helps drive the initial conversation when it comes to proceeding towards a more formal commitment.
