The Many Faces of Solar Power
Living in Nevada, the sun is a nearly continuous companion. This gives Nevadans a special chance to utilize solar radiation powers for excellent. In April, a trip of southern Nevada homes shed expert plumbing services some light on the topic of solar powered homes. Hosted by the American Solar Power Society, this Nevada branch of the National Solar Trip checked out homes that used both passive and active solar power, thermal hot water systems, and other environmentally functions. Nevertheless, unless you're a green innovations specialist, or took the trip, you might not know the distinction in between passive and active solar, or how thermal hot water is different than average. Let me assist you understand!
Active solar technology is the one that many people might be familiar with. It includes having a photovoltaic panel that collects the sun's energy and converts it into electricity. These have a battery where energy is saved, so electricity can still be utilized at night, and, to a certain degree, on cloudy days. Photovoltaic panel are an outstanding way to make electrical energy, especially in remote areas. While they are reasonably pricey to set up, and do require some upkeep, they offer reliable and complimentary electrical power, even in environments far less warm than Nevada's.
Passive solar technologies are far older than active ones, and involve using the natural heat and light the sun produces, without converting it in any other method. 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 power, and are releasing it. Some materials are much better at taking in and saving that heat than others. For example, wood insulates, indicating it will obstruct temperatures, whereas stone will absorb and release temperatures. Houses that are built to take advantage of passive solar are frequently constructed of brick, adobe or concrete. Cob is another passive-solar-friendly and ancient building product that is going through a revival of sorts. It is made from sand, clay and straw, comparable ingredients as adobe, however adobe is baked into bricks and stacked, whereas cob structures are free-formed while the product is damp. Passive solar homes typically have a lot of windows lining their south walls, and less so their trusted top plumbers east and west walls, with little to no windows on the chillier north sides. These windows do two things. Initially, they provide natural light inside the home, one aspect of passive solar. Second, they enable heat to come into the home. If the home has a stone tile floor and even walls, that tile will take in the heat, launching it later on when the outside temperature level drops.
Passive solar homes can be created to be cool in summer while using the sun to warm them in winter. For instance, if shutters are closed during summer season, the home will remain much cooler. Likewise, the height and angle of overhang can be considered to optimize the windows direct exposure to low winter season sun, however decrease direct exposure to the high summer season sun. Alternatively, I saw a fascinating example of somebody planting deciduous trees on the south side of their home. In the winter season, the trees had no leaves therefore let in a lot of light and heat. In the summertime, their thick greenery offered shade that kept the house cool.
So that is the significant distinction between active and passive solar technologies. Given that passive solar is basically free, it would be sensible for any designer or home designer to take it into consideration when constructing new homes. Well created passive solar homes can significantly decrease their electrical energy requirements. And while active solar is brilliant technology, it still takes lots of resources to create. Plus, it may be superfluous in an area with an existing electrical source.
As for thermal water heating, it too is a really basic idea. Home made thermal water heaters can be as basic as an outside water tank painted black, but that's a little crude for the majority of tastes. Nevertheless, there are a variety of designs out there. Some have panels that are metal painted black and confined with glass, with copper pipes filled with water running through 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 linked to a heat transfer loop, where water in a storage tank is warmed. Whatever system you use, thermal water heating is remarkably affective.
There are a lot of methods to make the most of the sun and use less electrical power. Check out next year's National Solar Trip to see them on your own.
