Download the latest version of StartSun Energy Community Feasibility Calculator

StartSun project has developed a free and easy-to-use digital tool that helps individuals and small organizations explore the feasibility and potential of creating or joining a solar energy community in their area. This tool is the first to be tailored specifically to households and small organizations. In addition to estimating solar energy production, the tool includes a unique module that inspires users identify suitable energy community models based on their specific circumstances.

The calculator guides users through four key steps: 

1. Energy Consumption – Users input their monthly electricity usage and current electricity costs.
2. Solar Plant Setup – They define the parameters of their planned solar installation, including location, capacity, and orientation.
3. Financial Inputs – Users can enter investment details such as loans or grants or rely on default cost estimates.
4. Community Questions – A short questionnaire helps determine the most appropriate energy community model based on the number of members, goals, and other characteristics.

The tool generates a comprehensive summary that includes monthly averages, projected solar production, household consumption, cost savings, and return on investment. It also highlights the three most suitable energy community archetypes based on the user’s inputs, offering both technical and financial clarity.
