GreenDays is a digital advisor that simplifies the process of purchasing solar photovoltaic (PV) and energy storage for businesses and consumers.

By comparing quotes from expert installers in the user's region, GreenDays provides a transparent method that streamlines all the technical and financial data required to close a deal.The company's intelligent algorithm predicts the energy production of each quote by considering various relevant parameters, such as system components, design, meteorological data (e.g., radiation, temperature, and wind velocity), maintenance costs, and system losses (e.g., degradation and shadow).

This approach enables GreenDays to offer a comprehensive view of the potential benefits and costs associated with each quote.
