How Do Green Roofs Imprive Efficiency Of Solar Panels

Panels installed over the green roof performed best generating an average of 1 4 percent more energy as compared with those over the white and black roofs said a press release by university of kansas.

How do green roofs imprive efficiency of solar panels.

University of kansas press release. An example of one of their roofs is seen in figure 1. Click here to read the full article sourced from international business times. It is suggested that the panels optimum efficiency is at an ambient air temperature of approximately 25 c.

1 cool your roof cool roofs are lighter in color than traditional black asphalt or dark wood shingles and save energy by reflecting light and heat away rather than absorbing them. This is known as the albedo effect and many studies have documented significant energy savings from simply lightening the color of a roof. New studies show they can also boost the performance of solar panels. For installing solar panels and a green roof together and has done extensive research on the benefits.

Research has shown that the evapo transpiration from your green roofs vegetation can have an extremely positive effect on the efficiency of pv panels. By erin weaver green roofs are known to extend roof life conserve energy and reduce stormwater runoff and air pollution. Vegetated areas are naturally cooler than built up areas. Solar panels on green roofs like these in new york city can operate more efficiently because the surrounding air is cooled by plants.

In fact many surveys have proven that cleaning your solar panels once a year can maximize its efficiency by as much as 21 and improve returns on your investment. They found that green roofs can help reduce dust and air pollutants found on bare roofs which can improve solar panel performance and reduce the maintenance needed green roof technology 2015. For every degree above this the pv panel can lose anything up to 0 5 efficiency. Green roofs improve solar panel efficiency.
