Advantages of Solar Power

Living in Nevada, the sun is an almost consistent companion. This gives Nevadans a unique possibility to use solar radiation powers for good. In April, a tour of southern Nevada homes shed some light on the subject of solar powered homes. Hosted by the American Solar Energy Society, this Nevada branch of the National Solar Tour explored homes that used both passive and active solar power, thermal hot water systems, and other environmentally characteristics. However, unless you're a green technologies professional, or took the tour, you may not know the difference between passive and active solar, or how thermal hot water is different than average. permit me help you understand!

Active solar technology is the one that most people can be familiar with. it includes having a solar panel that collects the sun's energy and converts it into electricity. These have a battery where energy is stored, so electricity can still be used at night, and, to a definite extent, on cloudy days. Solar panels are a fantastic way to make electricity, particularly in remote areas. While they are moderately expensive to set up, and do need some maintenance, they provide prestigious and free electricity, even in climates far less sunny than Nevada's.

Passive solar technologies are far older than active ones, and involucres utilizing the natural heat and light the sun build, without converting it in any other way. Have you ever discovered that after a long, hot day, south-facing rocks, pavement or brick and adobe buildings will radiate warmth? They have spent the day passively collecting solar energy, and are releasing it. Some materials are better at absorbing and storing that heat energy than others. For example, wood insulates, meaning it will block temperatures, whereas stone will absorb and release temperatures. Homes that are built to profit from passive solar are often constructed of brick, adobe or concrete. Cob is another passive-solar-friendly and elderly building material that is going by ways of a revival of sorts. It is produced of sand, clay and straw, similar ingredients as adobe, but adobe is baked into bricks and stacked, whereas cob structures are free-formed while the material is wet. Passive solar homes generally have a lot of windows lining their south walls, and less so their east and west walls, with little to no windows on the colder north sides. These windows do two things. First, they provide natural light inside the home, one aspect of passive solar. Second, they permit heat to come into the home. If the home has a stone tile floor and even walls, that tile will absorb the heat, releasing it later when the outside temperature drops.

Passive solar homes may be designed to be nice in summer while utilizing the sun to warm them in winter. For example, if shutters are closed all through summer months, the home will remain much cooler. Also, the height and angle of overhang may be considered to maximize the windows exposure to low winter sun, but minimize exposure to the high summer sun. Alternatively, I saw an attractive example of somebody planting deciduous trees on the south side of their home. In the winter, the trees had no leaves and so permit in a lot of light and heat. In the summer, their thick greenery provided shade that kept the house nice.

So that is the drastic difference between active and passive solar technologies. Since passive solar is basically free, it would be smart for any architect or home designer to take it into suggestion when building new homes. Well developed passive solar homes can greatly lower their electrical energy requires. And while active solar is brilliant technology, it still takes several resources to originate. Plus, it can be superfluous in a field with an existing electrical source.

As for thermal water heating, it too is an extremely simple concept. Homemade thermal water heaters may be as simple as an outdoor water tank painted black, but that's slightly crude for most tastes. However, there are a range of styles out there. Some have panels that are metal painted black and enclosed with glass, with copper pipes filled with water running by ways of them. This water will heat, and is then pushed by gravity into an insulated storage tank. Some solar water heaters use a similar set-up but with tubes filled with anti-freeze that are then hooked up to a heat transfer loop, where water in a storage tank is heated. Whatever system you use, thermal water heating is surprisingly affective.

There are a lot of manners to profit from the sun and use less electricity. verify out next year's National Solar Tour to see them for yourself.
