Transcript of Solar Panels and Solar Energy

  1. 1. Solar Panels and Solar Energy Solar panels soak up energy from the sun and turn it into electricity that can be used to provide power for homes and businesses. They are considered to be a form of clean or "green" energy since they don't use fossil fuels or cause pollution. As the price of fuel is increasing people are becoming more interested in this form of energy generation. This article will help you decide if you want to opt for solar energy in your home. Benefits of Solar Panels There are many benefits to installing solar panels into your home or office as part of your electricity providing sources. These include: They give you renewable energy sources from the sun's rays with very small carbon footprint compared to other sources of energy like coal. It is cheaper to provide energy to remote areas with solar panels and you can store it up for future usage. Solar panels often come with long warranty cover. Solar panels are low maintenance and have no moving parts. They can sometimes raise value of the home. They don't cause pollution or give off harmful byproducts. It only takes about a year to get the money back you invested in them in most cases. Solar panels don't produce noise like other types of electricity generating materials. Since they are installed on your roof, they don't take up space inside the home that could be used for other reasons, thus saving space. Solar panels produce safer energy since they aren't combustible like many other fuels used to heat or power a home. The home using solar panels can produce enough power to be independent of the electric company in some areas. Just How Do Solar Panels Work?
  2. 2. Solar panels are made of a bunch of photovoltaic cells made of positive and negative layers of silicon under special sturdy type of glass. Once they are put under the sun's rays, it activates the photovoltaic cells and captures energy in the form of electrons that go to a connected circuit and then that generates electricity when it travels down attached DC wires. There are two basic types of solar power panels: a stand along power system or SAPS or a main grid connected system. Mains Grid Connected Solar Panels These types of solar panels are connected to a main power supply. Once the panels soak up the sunlight, they produce the power and a grid connected inverter changes that power from DC into either 120 or 240 voltage (depending on your needs) and then you can use it for your electrical items. SAPS - Stand Alone Power System Solar Panels SAPS solar panels are separate from the main power grid and instead store the energy they soak up and hold it in a battery until needed. Then the electricity is fed through the wires to a regulator that regulates the power going into the storage batteries. These deep cycle batteries last for several years and the power in them can be used to power items in your home. This system has its advantages since your home would be separate from the main power company and generating all your own power, while the other is connected to a main power company and if it lost power, so would you since no power is actually stored in your home. Solar Panels Prices Are Coming Down Over the years, solar panels and solar energy has gotten cheaper to purchase and use. Systems have come down in price since the 1970s more than 50 percent. Some electricity companies even give you a rebate to get money back if you install solar panels. The amount of solar panels you need depends on the size of your home and what you need to use it to generate energy for. You can find calculators online that can estimate what you will need, or the place you buy the solar panels from should be happy to estimate it for you. You don't have to buy them to provide 100 percent of the power in your house, you can have enough
  3. 3. of them to make them a backup or additional source of energy to help you to save money and help save the environment too. Ways To Save Money With Solar Panels There are different kinds of solar panels: monocrystalline, polycrystalline, and ribbon, with the most common being polycrystalline panels. These are considered to be the most cost effective because the monocrystalline ones have gaps of space on their panels even thought they produce higher amounts of solar energy. That makes both of these types somewhat balanced overall in the amount of energy you get versus the amount of money you pay for the solar panels. On the other hand, the ribbon style of solar panels are not considered to be very effective, although less costly, and most contractors advice against their usage. Plus, there are different kinds of batteries you can get for your solar panels. Most of the time the contractors that install solar panels recommend what is called a deep cycle battery since these don't require much maintenance. It is also more cost effective to use LED lighting systems if you are using solar panels to give you electricity for your home. That's because they use less energy than incandescent bulbs do. Solar Power Usage Rising Fast Solar energy through the usage of solar panels is on the rise, especially since many people are concerned about the environment and wasting resources on our planet. It is a form of energy that is inexhaustible and makes the user less dependent on fossil or other fuels and doesn't pollute the Earth. It is cheaper, and is used in many countries around the world as it grows more in popularity. The bottom line is that solar panels are a good way to generate a large portion of energy to produce electricity in your home and if you purchase them it can drive your electrical bill down. They are therefore good for the consumer and good for the environment. If you would like to install solar panels in your home then you definately persue this method of energy generation.
