Solar in Texas
There is no question that solar energy has been a hot topic for years. Environmentalists are quick to point out its benefits both economically as well as environmentally. Unlike fossil fuels that will one day be depleted from the earth’s stores, solar power will be around for as long as the sun, which makes it one of the most reliable resources for energy that we can have.
However, some have questioned whether the benefits are as good as claimed. In fact, there are quite a few groups that have been actively opposing it.
Solar Energy: The Good
Fortune Magazine said it best when it predicted that solar energy would be the technology to watch in the coming years. It’s not just sweeping the nation but the world with countries like
China and India making massive investments in it.Because so many are now getting on the bandwagon, what was once an expensive investment and a privilege few people could afford, the cost of solar power is steadily dropping into an affordable range for more people.
Economically, this is a windfall for everyone. Whether you’re a homeowner, business, or a corporation being able to lower the cost of electricity can have a positive impact on your bottom line. A solar powered system can even
Solar Energy - The Future's So BrightThere are many advertisements and campaigns carried on everywhere to use alternate energy in spite of traditional energy. Many governments promote this campaign and give subsidies to make and use the alternative energy. There are some alternate sources of energy available in today's world such as wind energy, hydropower energy and solar energy. Except solar power, all sources are very expensive and take lot of time to get into use.But in case of solar energy you can start within few days of time and more important thing is that you can make solar power panel in your home with a little cost and your used old household elements with solar kits. Due to cheaper cost and frequent electricity disruption, nowadays many people are looking for alternate source of energy. Before we start, we should consider few things.You have to calculate your power usage, there are so many work sheets available on Internet by the help of which you can calculate power consumption of your appliances. When you prepare actual need of your power consumption do not forget to add minimum 10% to 15% extra as energy loss in power storage system.You have to look for solar kits in which all the required materials for assembling the panel are present along with the instructions. Decide whether you want to use solar power for some time or longer. Consider the availability of sunlight in your area and the capacity of storage box.After considering these points you can install your solar power panel on the roof of your house or in any open space.Benefits of solar energy:1. Solar energy is pollution free and has no negative effect on our environment. 2. It is easy to use this for any appliance provided sufficient capacity of solar power panel and storage battery is available. 3. It is very useful in remote areas where traditional electricity is not available. 4. It can be used for smaller appliances also, which consume negligible electricity. 5. It is economical than any other source of energy. 6. It can be assembled in very little time.The benefits and convenience of solar energy help us predict that it will become common very soon worldwide. Solar panels hold a wealth of benefits, both for individuals and for the world at large. Economically, solar panels promise to lower the cost of electrical power. Environmentally, solar panels can give us cleaner power, sustainable power that will not require further damage to the environment. Solar power can reach remote areas. It can carry education, or urgently needed medical information.The effects of clouds on a solar panel, though, might diminish those and other promising benefits.The effects of clouds on a solar panel might make it far less efficient in certain parts of the world and at certain seasons.For that reason, people who are considering solar panels for their homes are often heard to ask: will clouds affect my solar panels?Will Clouds Affect My Solar Panels?Clouds do affect solar panels. The amount of power your solar panels can produce is directly dependent on the level of light they receive.In full, bright sunlight, solar panels receive maximum levels of light. During those "peak" sunlight hours, your solar panels will produce power at their maximum capacity.When clouds cover the sun, light levels are reduced. This does not shut down power production, however. If there is enough light to cast a shadow, in spite of the clouds, your solar panels should operate at about half of their full capacity. Thicker cloud cover will reduce operations further. Eventually, with heavy cloud cover, solar panels will produce very little useful power.The Good News!The effects of clouds on a solar panel can be surprising good, however. Incredibly, your solar panels will put out their ultimate amount of peak power during cloudy weather!As the sun moves into a hole between the clouds, your solar panels will see something wonderful. They will see full direct sunlight "plus" reflected light from the clouds! They will drink in more energy than they could on a cloudless day!The effects of clouds on a solar panel could then produce peaks at or above 50 percent more than its direct-sun output!Meeting the ChallengeThere are ways to meet the cloud challenge.1. If you often have clouds in the afternoon, but mornings are clear, aim your solar panels slightly toward the east.2. Be sure you use a large enough battery system to maximize the amount of power stored for use when the clouds arrive.3. Make sure your controller has plenty of headroom over the rated panel output power so that it can absorb the surges when the sun reflects off the clouds.Those tricks and more are practiced in cloudy regions of the world where people have sprinted far ahead of the United States in their use of solar panel energy.Effects of Clouds on a Solar Panel in GermanyGermany is typically a very cloudy country. Read about the climate of Germany, and you will find that it is "temperate and marine; cool, cloudy, wet winters and summers; occasional warm mountain (foehn) wind" according to Nation Master's website.In spite of its cloudy climate, though, Germany is by far the world's biggest user of solar panels. If you lived in Germany, you could sell back to the main power grid all of the excess electricity produced by your solar panels. Why would I even care in such a cloudy climate? If clouds affect my solar panels too much, I would not worry about selling back to the main grid.In 2006, Germany opened the largest solar park in the world. Germany also has Europe's most modern solar housing project - a solar village of 50 solar houses that produce more energy than they use!Will clouds affect my solar panels? Even if I lived in Germany, the effect would not be enough to forego solar power.Tip: There are few places that are so consistently cloudy that solar power is out of the question. Improvements are being made constantly, and even solar panels small enough to fold into a briefcase can produce helpful amounts of power.
Solar Energy is the Way of the FutureSolar power electricity installations are gaining moment all over the world. Stock of fossil fuels is fast depleting and alternate natural energy solutions, like solar power electricity is becoming popular.Natural energy solutions are environment friendly with little or no air pollution and no emissions or greenhouse effects. Solar power electricity production is also free of noise pollution.How is solar power electricity produced?It is produced by converting light from the sun into electrical energy using a silicon wafer / semiconductor called a photovoltaic cell. This technology is simple and easy to maintain.What are the main parts of a typical residential solar power electricity system?A typical residential system would have 4 key Parts:1) Solar panel array2) Charging controller3) Batteries4) InverterSolar panel array: Solar panel array is made up of several solar panels. A series of photovoltaic cells working in unison in a module form the solar panel. The solar panel array needs to be exposed to sunlight, and the array is normally installed on rooftops where sunlight exposure is more. The solar array converts light energy into solar power electricity. Electrical energy in the form of 12 volts (DC) is produced by the solar panel array.Charging controller: The charging controller is the device that controls the amount of charging for the batteries. Batteries should not be overcharged, neither should they be undercharged. This device, which sits between the solar panel array and the battery bank, controls the charging.Batteries: These are deep cycle batteries used for storage of solar power electricity produced by the solar array panel. The 12 volts (DC) produced by the solar panel array is stored in the batteries. The charging controller regulates charging, thus extending the life of these batteries.Inverter: The output from batteries is 12 volts (DC) and can run only devices that work on 12 volts (DC). Most home appliances work on 110 / 220 volts (AC). Hence 12 volts (DC) needs to be converted into 100 / 200 volts (AC). The inverter does the job of converting 12 volts (DC) into 110 / 200 volts (AC).Along with these four main components several other hardware accessories, wires and connectors would be required to have the complete solar power electricity system functional.
