At least as much electricity in a year from solar panels on its roof as it uses.

How many solar panels are used in the bullitt center.

The bullitt center aspires to be the greenest commercial building in the world by pursuing the living building challenge which includes a net zero energy goal to produce all the energy the building uses. 570 photovoltaic panels cover the bullitt center roof each with a rated capacity of 425 watts meaning the total array will generate 242 000 watts 242 kilowatts of power at noon on a sunny day. These solar panels have no moving parts to break or wear out and are guaranteed for 25 years. The living building challenge group granted an exception to the sourcing radius requirement because of the need to purchase high efficiency pv panels.

These elements reduce the six story buildings annual energy requirement enough that it operates on energy provided by a roof top solar array and manages its own water and waste needs onsite on an extremely tight urban block in rainy overcast seattle. It was calculated that the panels along with 20 sunpower inverters will generate more than 230 000 kwh of energy in an average year. In 2014 the bullitt center generated 60 more energy than it used due largely to efficiencies that exceeded expectations. To achieve this goal the bullitt center has 575 solar panels on the roof creating a 14 000 square foot array to generate electricity.

Nw wind solar designed a special racking system that extends beyond the bullitt center walls to install 575 425 watt sunpower photovoltaic panels on the roof. The bullitt center is located at. The northwest s variable amount and intensity of daylight affects solar production values so scaling the system to meet the needs of a six story building required a 244 kw array with 575 solar panels which installed cover an area larger than the footprint of the building creating. Energy is generated by a large solar panel array composed of 575 panels on the roof of the building along with energy conservation measures that cut the building s energy consumption to approximately 15 of a typical office building of similar size.

There are 575 pv panels on the roof of the bullitt center at 425 watts per panel manufactured by sunpower corporation of san jose. Simply put it is the most energy efficient office building in the country.
