On paper, it pays to cover the roof with solar cells. Namely, this reduces the electricity bill, and can even bring income. But first you have to think about the costs, because photovoltaics are not cheap, and even before that you have to ask yourself whether your roof has solar potential at all. Getting a professional opinion on whether it's worth installing solar panels on your house can really hit your wallet, especially if the answer is 'no'. As with many things, Google now also has an answer to the question of whether your roof is suitable for a solar power plant.
Above us almost all the time is this huge one power plant - the sun, which shares daily free energy for everyone. But most of the money that falls from the sky does not catch. Why? Because the beginning is quite difficult. Before that, you have to answer many questions. How much do solar panels cost? How much time does the sun shine on our roof during the day? What is the lifespan of solar cells? What is the purchase price of electricity? And so on. Now you don't have to look for these answers yourself, because they are here Google Sunroof, which finds them for you in a fraction of a second. He tells you Does your roof have the potential for solar cells?e and calculate how much money you will save, since the installation of solar cells, as we know, contributes to melting electricity bill. Google was able to answer all of this already, but it did not have a "univocal" answer, that is answers in one place (but he had all the necessary information), and now he has it.
The world has long been documented with the help of satellites (Google Earth map) and knows so well the size and position of the roofs, and in its calculation it also takes into account the shadow cast on it by surrounding buildings and nearby trees. But you also own it data on the average number of hours of solar radiation (from these calculate how much solar energy the building can receive in one year). And how will we check the potential of our roof for solar cells in the future? It will be necessary to enter the system just enter our address, and everything else will be done by Google itself. But he will go even further. If you trust him with how much you spend on electricity and its price, you will also get a calculation how much you would potentially save if you switched to solar power, how much the investment will be (he is looking for local providers of such services) and what proportion of the roof should be covered by panels for the most rational production.

Admittedly, there is skepticism in the world in this field, because solar energy lacks stability, so other sources are imminent. A combination with household batteries as is Tesla Powerwall and similar Mercedes product, promises us more a self-sufficient energy future and less dependence on the electricity grid and non-renewable energy sources. Google with Project Google Sunroof- hobby project of Google engineers, which was created within the 20 percent of the time they have available for developing projects of their own choice - namely promotes a green economy, dispels myths about solar energy and will try to use it to bring solar energy closer to people, initially only in the USA (pilot in San Francisco, Boston and Fresno, California), but one day it should "shine" the whole world. This is not the only green project of Google, as the technology giant also announced a map that will show the level of pollution in an urban environment.
