De fato, a empreitada exigirá tecnologias espaciais avançadas, não só para absorver a energia solar e enviá-la de forma eficiente para a Terra: sua própria construção exigirá vários saltos no desenvolvimento de tecnologia robótica. No entanto, é preciso haver mudanças significativas nos acordos internacionais de cooperação espacial antes que o projeto saia do papel.
How much you save with solar panels depends on your local weather — they’re a better deal in sunny Denver than dreary Seattle — and how much electricity costs in your market.
A few notes on choosing an installer: The U.S. Department of Energy recommends approaching this step with care. Ask potential contractors about their level of experience installing both on-grid and off-grid photovoltaic systems. Most homeowners will want on-grid installation, meaning your solar system is interconnected with the local power grid. Be sure the contractor you hire is licensed and certified and that there are no legal complaints against them. Your state electrical board and the Better Business Bureau are good resources.
El Ministro de Energía, Jorge Bunster, inauguró oficialmente el proyecto “Planta Fotovoltaica en Intendencia de Antofagasta”, en una ceremonia que contó con la presencia del Embajador de Alemania en Chile, Hans-Henning Blomeyer-Bartenstein; el Intendente, Waldo Mora, y el Seremi de Energía, Carlos Arenas.
Eugene, Ore.-based Grape Solar was founded in 2009 and makes solar panels largely manufactured in Asia but assembled in the United States. The Grape Solar 390W panel has an efficiency percentage of 15.21, a solid number, and can handle 50 pounds of snow per square foot.
Currently, more than 9,370 megawatts of cumulative solar electric capacity are operating in the United States, enough to power more than 1.5 million average American homes, according to the Solar Energy Industries Association.
