About Blue Chestnut
We're on a mission to accelerate the transition to sustainable energy by giving homeowners the tools to make the best decision for their energy system.
Our Story
Founded in 2024, Blue Chestnut emerged from a simple observation: while sustainable energy solutions are more accessible than ever, many homeowners struggle to find reliable and understandable information about renewable energy systems. Installers always promise high returns for solar, heat-pump, and other installations. However, the savings often are lower than expected or do not materialize at all. We build simulation tools for homeowners to accurately calculate the savings of their energy system.
