Google has launched a pilot project to help US householders find the best solar plan installation.
Project Sunroof creates a personalised roof analysis for customers interested in buying solar panels.
Those who want to take part in the programme need to provide their address and the company will use Google Maps to collect information.
It will calculate how much sunlight hits a roof per year and depending on different factors such as temperature, shadows and the positions of the sun over the course of a year it will recommend an installation size.
It aims to help householders generate close to 100% of their electricity use.
The tool works out how much money a householder could potentially save by installing solar panels and connects them with local solar providers.
In a statement Google said: “As the price of installing solar has gotten less expensive, more homeowners are turning to it as a possible option for decreasing their energy bill. We want to make installing solar panels easy and understandable for anyone.”
