Google uses solar panels

    Google supports the movement of environmentalists and uses PVC furniture, paints that do not contain volatile organic components. And it came as no surprise to anyone that Google was deploying the largest commercial solar system in the United States (1.6MW), which covers most of the buildings on the company's premises. At an ETech San Diego conference this week, Google’s project coordinator, Anthony Ravitz, talked about how and why Google deployed such a system.

    Ravitz says that Google will return the money invested in the project in 7.5 years, after which it will use cheap energy for decades. Solar panels have the unique ability to take more energy when loads are high - the afternoon period of the highest load.

    Installation of equipment costs a lot of money (although prices are gradually falling). Ravits does not give exact figures, but says that the project has become a reality thanks to subsidies PG&E (a kind of California GAZPROM and RAO UES in one person :)) and a generous federal tax credit.

    Now on Googleplex’s flat roofs, 9,212 Sharp photovoltaic modules are installed, each of which is capable of generating 208 watts of power in maximum light conditions. To increase the area of ​​solar panels, Google installed them in car parks, thereby killing two birds with one stone: firstly, more energy is generated, and secondly, cars do not heat up on hot days. The installation can generate 30% of the capacity needed during peak Google consumption, or about a thousand California homes.

    This is a graphic illustration of the coincidence of commercial and environmental interests, and Ravitz hopes that other firms will follow the example of Google and begin to look closely at alternative energy sources.
