About

GreenDays is a digital advisor that simplifies the process of purchasing solar photovoltaic (PV) and energy storage for businesses and consumers. The company provides a transparent method that streamlines all the technical and financial data required to close a deal by comparing quotes from expert installers in the user's region. GreenDays' intelligent algorithm predicts the energy production of each quote by considering various relevant parameters, such as system components, design, meteorological data, maintenance costs, and system losses. This approach offers a comprehensive view of the potential benefits and costs associated with each quote. They also offer solutions for local authorities to promote residents' transition to renewable energy, including organizing municipal purchasing groups, managing competitive processes, and providing knowledge portals and human support. Their solutions include GreenDays.co.il, a platform for comparing and purchasing solar systems, and SolarDesign, a system for the design and simulation of solar installations.
