Green roof vs solar panels.

Green roofs and solar power the biosolar approach. Solar panels and green roofs are traditionally used separately to maximize the benefits from each one. Pv panels also increase the diversity of green roofs by providing different niches for organisms to live. On a hot day a standard roof can easily reach temperatures of 45 o.

In summer the lush growing and diverse blanket of green roof plants are like small air conditioners for the heat sensitive pv elements. At the same time these plants will retain more than 50 90 of the annual rainfall preventing it from running off into our already stressed sewer systems and waterways. However using them together so that a building can get the benefits of both is a new idea. What is a solar green roof.

But in fact both systems can benefit each other too. As we ve stated above a standard four inch extensive green roof costs around 8 17 per square foot while 350w solar panels cost around 26 per square foot. According to tesla the average tesla solar roof cost a property owner can expect to pay is around 21 85 per square foot this estimate was made based on a roof made of 35 percent solar tiles. Very importantly pv panels are much more affordable and easier to retrofit than transforming a hitherto normal roof into a green roof despite the high cost of the panels and inverters.

Whilst it is increasingly common to combine solar panels with green roofs true biosolar green roofs are where green roof and solar technologies are integrated in a seamless fashion. Solar panels tend to cost a fair bit more than green roofs but you ll break even on your investment much quicker with solar. Pv panels in this temperature will produce around 10 less electricity compared with the panels installed on a green roof under the same conditions. Solar green roofs integrate standard solar electric panels with a traditional vegetated green roofing system.

Tesla solar roof cost. Realistically though for larger energy consumers the solar panels will make little more impact aside from their visibility. A biosolar roof generates energy as well as providing all the benefits of a green roof. There is substantial evidence from germany and switzerland that combining solar panels and vegetation can produce the following benefits.

In addition true biosolar green roofs especially on extensive green roofs is also designed to maximise biodiversity. In a common configuration solar panel mounting brackets are ballasted by the weight of the green roof layers eliminating the need for roof penetrations. Solar garden roof 1 in the united states fully integrated no penetration. As an estimate if you need 2 000 square feet of roofing on your home a tesla solar roof will cost a little less than 44 000 according to tesla themselves.
