Solar Proposals & Feasibility Studies

Feasibility Studies and Proposals

A feasibility study is the first step in the solar installation project development lifecycle. During this study, we gather the information necessary to assess the viability of solar using findings from multiple studies that identify critical design constraints and issues.


What is a Feasibility Study?

The feasibility study, sometimes known as a proposal, helps anyone who is selling or buying solar to better understand the key details such as the location of arrays, bill of materials, expected production, and even financial indicators such as ROI and payback.

Feasibility Study FAQ

Q: What’s the typical Delivery Time?

A: All proposal services have 1-2 business day delivery and are completed by solar experts with the best software tools available.

Q: What’s included in the report?

A: Every Feasibility Study includes a roof layout with dimensions and applicable fire offsets based on a 3D model, taking into account site obstructions such as structures and trees that cause shading and, therefore, less solar potential than an area that is shade free.

Q: What is a shade report?

A: The Shade repFrt shows the solar array overlaid on a 3D model of the roof. Each array is located in an optimal location, summarized by array showing the amount of panels, the azimuth and tilt, and the annual solar access, which is used to estimate the solar system's annual production by the month.

Q: How are the solar savings calculated?

A: An in-depth analysis looks at the previous year's utility consumption to understand how much energy is required to be offset by solar, and then we estimate the performance of the solar system. This is shown visually using colorful graphs and informative tables that quickly illustrate the potential savings for the owner.

Q: Does it include Payback?

A: The more in-depth proposals include a 25-year cash-flow broken down annually. Most systems will have a payback within 7-12 years.

Q: What financial indicators are included?

A: For the more sophisticated buyer, accurate financial indicators such as cost, applicable incentives, the system's rate of return, and financial payback are included. And our free revisions mean the risk is small if there are changes.
