The notion of unlimited and free energy has naturally attracted the interest of the environmentally conscious and frugal to use solar panels to save money and the environment. You can begin and enter this world by building panels yourself. You will need to use a guide book and a kit that provides easy to follow instructions and includes videos as an aid. You will have to do your research to find what works for you. When used properly these kits are a great learning opportunity and help you power simple devices. More kits are coming on the market as there is enormous demand for trying this route to energy production. For those who do not want to go all the way yet, this is a good place to start. Solar energy production techniques are being refined and improved on, so it may be wise not to make major investments at this time. In fact as revealed in the British media in February 2010, scientists have discovered a plastic that can store and release energy and may make batteries obsolete.
Save money with solar panels you build yourself.
Solar panels are a collection of solar cells wired together. They produce an electrical current when struck by sunlight. Although, solar cells generate minimal electricity individually, grouped together they generate substantially more. You can save money by building them yourselves rather than purchase them prefabricated. You can easily purchase solar cells you will wire together to make a panel online. You can purchase good quality whole cells, or lesser quality cells that are cheaper but are blemished in some way. Pre-tabbed cells facilitate wiring. You can save up to half to three quarters of the cost, if you make the panel yourself compared to a premade panel. If you purchase the wood and pretabbed cells a panel can cost a little over 100 USD for a small system for a few small devices. If you use scrap wood laying around and tab the cells yourself, the cost can be below 100 USD per panel. You would need basic tools that can be purchased at the local hardware store. Silicone caulk, wood glue and for the wiring, wire cutters, wire strippers, a soldering iron and solder would also be needed. If you want to power your whole house, the cost will be steeper.
A simple model of a system produces energy with the cells, contains batteries to store generated power, a charge controller to regulate this power, and a power inverter to convert energy so it can be used to power devices. Choice must be made between the two types of inverters available in the market. These are the Modified Sine Wave and the True Sine Wave varieties. Such a system can use the standard sealed lead acid batteries also used in cars.
Do it yourself solar panels are possible.
What you need them for determines the number of solar panels needed. Do you want to power one device, a few or something more? The power bill contains relevant for calculations to be made.
Solar panels need sunlight of a certain intensity. This varies in the course of the day and in periods through the year. This intensity is measured by what is known as an insolation value. Different locations have different insolation values. Knowing yours is important to determine how many cells you need and panels are to constructed. This information is available online and helps guide you to need less panels or more. By dividing the kWh of electricity you will need to produce by the insolation value you can learn what is the amount of power required. Keep in mind that there will be a certain amount of loss of energy in conversion which is about 25 percent with the general quality of solar cells. Should you be in a location with a low insolation score, more and bigger solar panels are going to be required.
How to build solar panels for a simple system.
To build your own panels, knowledge about the different solar cells is a requisite. Two types of solar cells are readily available. The most efficient type is the monocrystalline cell. This is more costly, but delivers the highest energy output and lasts longer. Polycrystalline cells produce less power; but, they are also cheaper. A simple system can be devised relatively easily. After you have decided on the type of cells you want you can build such a system by gluing and mounting them on a strong backing board and wiring them. A thick piece of plywood can serve as a backing board. The wiring diagram included with the purchased cells indicates the different voltages they can produce. Decide on the voltage and thus the cells needed to produce it. Then, lay the cells in a rectangle to give you the size you need for the backing board.
Solar cells should be attached to a board and then encased in a weatherproof container. Silicone caulk is useful for attaching to the board that creates a panel. The cells in this panel are then wired.
The container requires a see through top made from appropriate material is needed for tranparency. The easiest material to use for the rest of the container is wood. The wood is cut to the needed dimensions of the enclosure and the different sides are screwed together. A hole is to be drilled to permit wires to exit the bottom of the should be devised. You can thereafter learn to save money with solar panels you build yourself.
