How Do Green Roofs Imprive Efficiency Of Solar Panels

This is known as the albedo effect and many studies have documented significant energy savings from simply lightening the color of a roof.

How do green roofs imprive efficiency of solar panels.

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. University of kansas press release. For every degree above this the pv panel can lose anything up to 0 5 efficiency. 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.

Research has shown that the evapo transpiration from your green roofs vegetation can have an extremely positive effect on the efficiency of pv panels. In addition the other amazing benefit of cleaning solar panels regularly is that it helps you in improving the durability of your solar systems. By erin weaver green roofs are known to extend roof life conserve energy and reduce stormwater runoff and air pollution. Similarly pv cells positively influence the performance of a green roof and create different habitats that will benefit the local environment.

It is suggested that the panels optimum efficiency is at an ambient air temperature of approximately 25 c. New studies show they can also boost the performance of solar panels. Green roofs improve solar panel efficiency. An example of one of their roofs is seen in figure 1.

The addition of vegetation beneath solar panels actually increases the efficiency of the panels and means more electricity is produced. 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. For installing solar panels and a green roof together and has done extensive research on the benefits. Vegetated areas are naturally cooler than built up areas.
