With the sunroof, Google wants to help pass solar energy

Google has a project in service and for the moment has the name Sunroof, intended to determine whether the roof of a building should be to install solar panels. Thanks to Google Earth, you can evaluate the energy potential of a roof considering exposure and estimate the potential savings.

China is the second largest polluter, like the United States who want to engage in an ambitious plan to reduce emissions of CO2 in order to combat global warming. With the Paris Conference on climate, COP 21, President Barack Obama just made his last fight before the end of his term expiring next year.

“There is no challenge that poses a greater threat to the future and for future generations that change climate, “he said, announcing a program that aims to reduce emissions from US power plants in 2030. The 32 percent energy renewables are at the heart of this plan, particularly solar and wind energy.

If the action is clearly laudable, it also represents a considerable economic attractiveness. The market for solar energy is expanding, and new players are interested in this.

Thus, the car manufacturer Tesla has unveiled its new model you sl to powerwall, a domestic battery that can store electricity provided by solar panels or AC power.

Like other giants of the high-tech, Google is also very sensitive to environmental issues and renewable energy. The Californian firm has launched a new project called S unroof surely foreshadows the great ambitions for the future.

The first homes in the UK that generates more energy than it consumes

The first homes in the UK that generates more energy than it consumes

The Solcer House in Cenin, Wales, was created as part of the Low Carbon Research Institute program. For every 100 pounds spent on electricity, this house will be able to generate 175 pounds in electricity “exports”.

L to first low-cost housing known as a house of ‘positive energy’, which can generate more electricity than its occupants may use, opened last Thursday in the UK.

The modest three-bedroom house built in just 16 weeks in an industrial neighborhood on the outskirts of Bridgend in Wales, costing 125,000 pounds and according to the designers of the University of Cardiff, will allow passengers to use the sun to pay the rent.

When using batteries to store electricity generated from solar panels placed on the roof and because of the thermal insulation, you may be able to export electricity to the national grid for eight months a year.

So for every 100 pounds spent on electricity, should generate export 175 there of according to Professor Phil Jones, whose team of Welsh School of Architecture project Solcer says specifically designed the house to reach the objectives the government proposed in 2006.

I also wanted to show that a house was perfectly feasible to reach the standard for affordable prices with current technology. So you pass the ball to builders demonstrating that, if you want, you can.

The cost of building a house of this type would be lowered if many be erected at the same time. Besides would be breaking that housing exported more electricity than they consume everything that it would. We must expect that the price per square meter in this house was given 1,430 euros, something close to social housing in Wales which lies between 800 and 1000 pounds.

Yesterday we discovered with puzzlement as a German neighborhood in the city of Freiburg produces four times more energy than it produces. And that has a city where they have 1800 hours of sunshine a year, nearly half some of the indexes you have some Spanish cities, so we can quickly show how badly we are doing in this regard in our country.

Something that has to do much with this one is that Google’s new project launched this week and has referred to as “Project Sunroof”. This will calculate the potential of housing for the possible implementation of solar panels. Say that calculates the hours of sunshine a year it receives the roof, for example, your home, so give an estimate of how much money ahorrariais.

Those who live in Boston, the San Francisco Bay and Fresno, have been invited to enter your address on the landing page for Project Sunroof which is the availability of hours of sunshine per year and how much money you would save if they were installed solar panels.

Google says that calculates this information with a database of aerial maps that get perform 3D modeling of the roof. Taking into account the shadows cast by the trees or nearby structures, and then calculates all possible positions of the sun over a whole year. It also includes the history of cloud patterns and temperatures that affect the production of solar energy.

Once all this is calculated, the amount of money you would save if you make leasing of solar panels for 20 years, using a loan to purchase or buy directly appears. Another advantage is that you can even change the amount of roof cover with solar panels if anything the user does not want to cover whole.

In a given example, a house with a rate of 1800 hours of sunlight per year would save $ 24,000 in 20 years including payment of solar panels. Now we just have to take account if you were in a province like Huelva which nearly doubles the number of hours of sunlight per year.
