Solar Mirrors

If you have ever seen a field with several mirrors pointing toward the sun you may be looking at a solar power system. These systems work to concentrate the sunlight to one area and use the heat to heat up the liquid that flows along the pipes. This system is called Parabolic-trough system. This type of system heats oil that is flowing through the pipe. The oil is hot and that is why it is used to boil water to power a steam generator which in turns powers electricity.

The reason that this system works so well is because the U-shaped mirrors attracts and collects the suns heat which is then transferred onto the receiver. The receiver absorbs the heat and transfers into fluid which helps to power the engine. The heat causes the fluid to swell up against the piston and that produces mechanical power. This type of power can be used to run things like generators or even an alternator that will produce electricity.

This system works great when because it uses molten salt that flows through the receiver. When the salt heats up it can generate electricity through the steam generator. The salt holds in the heat for several days before it has to be converted into electricity. Because this system uses so many panels it is mainly used for industrial solar power where acres of land can be donated to the Parabolic Trough. There can be enough power in the network that can create energy for several days or more. Because this system is so large that it allows the heat that it saves to be transferred days later.

Through this project and other solar power projects we can understand fully how solar power works. When we see how much solar power is conserved using these U shaped mirrors we can also understand how much energy is lost. Using concentrating solar power systems are beneficial to the businesses that use them because they won’t have so much time down when the power fails. Machinery is their only major concern and as long as their machines are taken care of there should be no problems. Industrial type of solar power can attract and trap a lot of heat from the sun during the day, especially using mirrors that will reflect the sunlight. It also helps to have this type of solar power out in an open field free of trees and vegetation that may grow around and at some point crowd the solar light out.

Scientist are continuously studying this theory as businesses use it to power their machinery. Steam power was what was used from the beginning with solar power and is still what most systems depend on to service their production needs. In the future, fields may eventually be full of mirrors that somewhat point up to the sky in hopes of generating enough sunlight to heat the world. Until then we will use the traditional methods of heating water, heating our homes and powering our electricity.

solar house

Mention the word solar in relation to a home and most people get ideas of panel systems on roofs. In truth, any home with windows is using solar energy.

Easy, Free Energy

You may not realize it, but you live in a solar home. In fact, every home you’ve lived in was powered with solar in one form or another. This concept is known as passive solar and can be used to save you serious money on utilities.

In every home, there is a room or set of rooms that bake in the sun during the day. Many people know this, but don’t realize it, when they complain about certain rooms burning up during the day while others are cold. The hot rooms, of course, are sitting in the sun all day. Since the sun is essentially a nuclear reactor, the power is sends to the earth is immense. Rooms can heat up to sweltering temperatures within 30 minutes as a testament to this power. Given some thought, you can use this power to passively heat your home.

Sunlight is very easy to put to work in a home. When you want heat, let it in. When you don’t, block the access areas. When sun energy enters an area through a window, the area is known as an isolated gain location. For instance, light streaming through a bedroom window will make the room an isolated gain area that heats up if you close the door. There are two excellent ways to put this to your use.

You can use sunlight to passively heat your home by adding isolated gain areas that track the path of the sun. Heat rises and evens out through a home. If the home has isolated access areas that track the path of the sun, you can gain free heat throughout the day. Most homes will have windows at the end of each home, but limited sunlight access through the roof. A good way to add heating to your home is through sun room roofs or skylights.

A second method for turning the sunlight into heat involves materials. Certain materials take longer to heat up in the sun, but also will generate heat longer once the sun has set. This is known as using thermal mass to heat a home. For instance, masonry materials universally collect and hold energy from the sun. Used for flooring below a window, the materials will heat up throughout the day. Once the sun sets, the materials will continue to expend heat for hours on end. If you doubt this, give some thought to how long your fireplace continues to radiate heat after the fire has gone out.

Using sunlight to heat your home passively will never replace the need for utilities. Minor home improvements, however, can help create heat during the day and make your home more comfortable.

With the new rollout of massive Government tax credits, state subsidiary programs and net metering, going solar makes sense. So, how do you pick an installer for your system?

As with any major part of your home, installation of a solar platform should be done by a professional. Many of the tax credit and rebate programs require professional installation and failure to do so can lead to the loss of the benefits. In short, there are practical and economic reasons to get it done right.

While a solar platform is necessarily a form of electrical generation, you shouldn’t assume every electrician knows how to install one. In truth, most do not. Here at SolarWatts, is what we specialise in. If you would like to talk to us about some Solar Panels. please contact us.

If you are looking around at other installers, make sure to ask some questions. Use your common sense and ask the same questions you would to any contractor installing something on your home.

If you are contacting other installers, the first question to ask is whether the installer has, in fact, installed systems before, how often and for how many years? You do not want a neophyte handling your installation. Installation experience is vital because certain elements of solar systems are very unique, particularly if you are tying into a grid system for a utility company. If you are tying in, make sure the installer has experience doing such installations, not just putting up solar panels.

The second question to ask is whether the installing company is licensed. Most solar installers will be required to have an electrician’s license. Contacting the state electrical board to ask about the installer is a wise move if they can not provide proof. For some state rebates, you may also have to use an installer that has a solar contractor specialty license. Again, the state electrical board should be able to help you out with this.

This may all sound a bit confusing, so let’s turn to the easiest method for finding installers. When in doubt, speak to us and we can help you decide which system is best for you.
