Living in Nevada, the sun is a practically constant companion. This offers Nevadans a distinct opportunity to utilize solar radiation powers for excellent. In April, a trip of southern Nevada homes shed some light on the subject of solar energy homes. Hosted by the American Solar Energy Society, this Nevada branch of the National Solar Tour explored homes that utilized both passive and active solar power, thermal warm water systems, and other environmentally functions. However, unless you're a green technologies expert, or took the tour, you might not know the distinction between passive and active solar, or how thermal hot water is different than average. Let me help you understand!
Active solar innovation is the one that many people might recognize with. It involves having a photovoltaic panel that collects the sun's energy and converts it into electrical power. These have a battery where energy is stored, so electrical power can still be utilized in the evening, and, to a particular extent, on cloudy days. Photovoltaic panel are an excellent way to make electrical power, specifically in remote areas. While they are moderately expensive to establish, and do require some maintenance, they offer reliable and free electricity, even in climates far less bright than Nevada's.
Passive solar technologies are far older than active ones, and involve using the natural heat and light the sun creates, without converting it in any other method. Have you ever observed that after a long, hot day, south-facing rocks, pavement or brick and adobe structures will radiate heat? They have invested the day passively collecting solar power, and are releasing it. Some materials are much better at absorbing and storing that heat than others. For example, wood insulates, suggesting it will obstruct temperatures, whereas stone will soak up and launch temperatures. Houses that are built to take advantage of passive solar are often constructed of brick, adobe or concrete. Cob is another passive-solar-friendly and ancient structure product that is going through a revival of sorts. It is made of sand, clay and straw, similar components as adobe, but adobe is baked into bricks and stacked, whereas cob structures are free-formed while the product is damp. Passive solar homes usually 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 supply natural light inside the home, one element 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 on when the outside temperature drops.
Passive solar homes can be designed to be cool in summer season while using the sun to warm them in winter season. For instance, if shutters are closed throughout summer months, the home will stay much cooler. Also, the height and angle of overhang can be thought about to make the most of the windows exposure to low winter season sun, but lessen direct exposure to the high summer season sun. Alternatively, I saw an interesting example of someone planting deciduous trees on the south side of their home. In the winter season, the trees had no leaves and so allow a lot of light and heat. In the summer season, their thick plant offered shade that kept your house cool.
So that is the major distinction in between active and passive solar technologies. Since passive solar is essentially complimentary, it would be wise for any designer or home designer to take it into consideration when building brand-new homes. Well created passive solar homes can considerably minimize their electrical energy requirements. And while active solar is dazzling technology, it still takes numerous resources to produce. Plus, it may be unnecessary in a location with an existing electrical source.
As for thermal water heating, it too is a really easy idea. Home made thermal hot water heater can be as simple as an outside water tank painted black, however that's a little crude for a lot of tastes. Nevertheless, there are a range of styles out there. Some have panels that landscaping tips for homeowners https://gitlab.uvm.edu/Connor.Klopfer/cs302_cadla/-/issues/2787 are metal painted black and confined with glass, with copper pipelines filled with water running through them. This water will heat, and is then pushed by gravity into an insulated storage tank. Some solar hot water heater utilize a comparable set-up however with tubes filled with anti-freeze that are then hooked up to a heat transfer loop, where water in a tank is heated up. Whatever system you use, thermal water heating is remarkably affective.
There are a lot of ways to take advantage of the sun and utilize less electrical power. Check out next year's National Solar Tour to see them for yourself.
