Solar energy has come a long way in recent years. Most recent and the most efficient solar technology allows owners to reduce their consumption of electricity and fossil fuels without filling the backyard with solar panels. With tax credits and the ability to sell energy to your electricity company, an investment in solar energy can pay for itself in the long term.
How solar cells work
The principles of solar energy have been built on the work of the 18th century French physicist Antoine - César Becquerel who discovered that change the pressure in a piece of metal produces an electric current. In 1883, Charles Fritts has built the first true solar cell, but equipment, that he chose, gold and selenium, only allowed 1% yield.
American inventor Russell Ohl replaced selenium and gold with silicon in the 1940s, the creation of the first modern solar cell efficiency by 5%. Other refinements have increased energy efficiency by 20%, which is what allows solar cells power a home.
How does solar energy work? In simple terms, when a beam of sunlight strikes a material, there is a chance that some photons will be released. These photons contain electric charge. Solar cells capture these photons and force them to move in one direction, which produces an electric current. This current can be exploited immediately, because it is in a solar calculator, or used to charge a battery is in lamps solar gateway available at home centers. More solar panels, more power you can generate.
Addition of solar energy in your home
Exploiting solar energy once meant huge installation of photovoltaic panels in the roof or backyard. These panels is always available and they are among the most effective choices, but a more recent, more architecturally pleasing option is solar shingles. Apart from a few extra shine, these may seem regular asphalt shingles and they transform your roof in a giant solar plant.
If you use signs or shingles, solar energy is collected and sent to a solar junction box, where it is converted to power your home. While the sun shines, you will have free, and most of the States allow you to sell any excess power you generate back to your utility company, which will significantly reduce your invoice. The solar junction box works alongside a standard plug-in to feed at night or when it's cloudy.
Some State-of-the-art systems incorporate large rechargeable batteries to keep the same current after that the sunset, but they may not provide enough power for all of our modern comfort such as air conditioners, computers, televisions and refrigerators. For this reason, a single solar house is still not possible, but a continuous improvement in the design of the battery and solar cell could be a reality in the next 50 years.
You can also use the Sun to produce hot water. A thermal solar system uses panels to collect heat than electricity. In the warmer regions of the country, the water is heated directly by the Panel and sent to a hot water tank. In regions where temperatures below the freezing point, an antifreeze solution is pumped into the panels. The solution is then pumped to a unit of heat transfer in hot water.
This reduces the amount of oil or gas necessary to generate hot water in your home. You always have a connection of gas or oil for cloudy days, but you may find that your use of these fossil fuels decreases considerably.
Heating solar liabilities can also be integrated into the design of a new home or a home addition. A good example of this is a sun room or the Conservatory with glass walls. Using materials that collect heat during the day and night, such as brick or stone rayon, the sun room can help to raise the global temperature of your home, which means less work and lower consumption of energy in your oven.
Exit at the yard, almost everything that runs on electricity can be powered by the Sun. There are these gateway solar lights, solar wall lights and fire safety. Warm up your pool or hot tub with a solar water heater, and mowers first solar lawn are the way we market, although their long and short of the battery load time make it more suitable for smaller yards.
Generate savings over time
Solar energy conversion involves steep initial costs. A system electric typical house costs around $ 20,000, including solar panels and solar junction box. Systems of shingles can be more expensive, according to what roof, you need to cover.
It may take some time for the system pay for itself, depending on your energy consumption and costs. It is rare that consumers obtain an audit of the local utility to produce energy, but it may happen in the sunny areas of the United States. Most owners will see their savings to build each month, in the form of lower energy bills.
The Federal Government offers also incentives for the installation of solar systems. The Declaration of 2008 economic emergency stabilization, homeowners can deduct 30% of the cost of solar equipment in their income taxes. The $2,000 cap is eliminated for solar systems installed after December 31, 2008, and the taxpayers who use the alternative Minimum tax are eligible for the credit. You may also be eligible for local levels tax deductions and State.
A solar collector of the swimming pool or hot tub cost a few hundred dollars, so that a fresh thermal solar system thousands. These will pay for themselves within a few years in annual energy savings.
While solar power was not perfected yet, it has come a long way in terms of efficiency and performance. As the price of energy continues to grow, adding solar on your home is a way to go green with the benefits of saving for the long term.
