What is Project Sunroof?

Project Sunroof puts Google’s expansive data in mapping and computing resources to use for people and organizations interested in solar power, helping illustrate the potential of solar power for a single house, and with the introduction of the data explorer, the potential of solar for zip codes, cities, counties and states.

What is solar photovoltaic roof?

Solar photovoltaic (PV) roofs play a significant role in the utilization of renewable energy in buildings. This cluster, the largest among all, comprises 51 documents and is primarily associated with the keywords renewable energy, building envelope, passive design, tropical developing country, and domestic residential power.

Can solar PV roofs be integrated with building elements?

A comprehensive analysis of research on solar PV roofs reveals that integrating PV components with building elements (roofs, sunshades, and louvers) is a common form in practical applications. The design challenge lies in finding a balance between the original functionality of the components and the added photovoltaic performance.

How much solar power does a roof produce?

In some cases, way more than you probably need. According to our calculations, the average-sized roof can produce about 21,840 kilowatt-hours (kWh) of solar electricity annually—about double the average U.S. home's usage of 10,791 kWh.

Does Project Sunroof have solar data?

We currently have solar data for portions of 50 states and Washington DC. See if we’ve got you covered. Project Sunroof is a solar calculator from Google that helps you map your roof’s solar savings potential. Learn more, get an estimate and connect with providers.

Will my roof generate solar energy?

Realistically, your roof’s solar generation potential will be less than that. It’ll likely still exceed your typical household energy needs, but real-world constraints like roof space, sunlight exposure, and equipment specifications play a huge role in your panels’ actual generation.
