Not all solar cells are the same and how you make them can make a difference. Different types of solar cells vary not only in price, but in the different features they present. There are currently three different types of solar cells: Monocrystal, Polycrystal, Amorphous.
Monocrystal panels are basically made of a single piece of silicon that has been cut into pieces and nested in a metal retainer. They are slightly more expensive than the policrystal type, but their energy yield is greater and they are more efficient under poorer light conditions.
Not surprising the policrystal type are more easily found in the marketplace because they're less expensive in the manufacture of solar pannels as they are made of a large number of smaller pieces of silicon rather than a single piece, and as a consequence they look like a mosaic of pieces of shattered glass.
Amorphous solar panels are produced differently in that small minuscule pieces of powdered silicon are sprayed on metal plates which are usually alluminium in composition. Although Amorphous solar pannels are less expensive to manufacture, they present less efficiency to a level of 50% of the monocrystal type.
On the positive side, amorphous panels are shadow protected and have a longer life span, making them more popular in stressful situations such as in the boating industry. These thin film panels are manufactured from silicone, but the silicon in them has no crystal structure.
These amorphous panels can also be manufactured using copper indium diselenide (CIS) and cadmium telluride (CdTe). Since they don't depend on the manufacture of silicon crystals, a process that is expensive and takes longer, they can be produced faster and less expensively, and their versatility allows them to be installed on surfaces that are both rigid and flexible.
Consequently, a well thought out plan is needed regarding the real energy need your Homemade Solar Panels will be expected to meet. This will help reduce expenses, and raise the effectiveness of the end product.
Currently it is possible to purchase solar pannels that will provide 50 watts at a cost of approximately two hundred and fifty dollars. Hence, for a small amount it is possible to charge a 12 volt battery, which is more than enough to satisfy average energy needs in a boat or motorhome.
Visually, sleek amorphous panels will look good in most situations. If they are to be placed on an uneven surface then these film panels are the answer.
There is a wide range of "DIY" informational products and materials available for your home or business needs.
Solar Pannels - Government Grants
The US government has recently announced a series of grants and tax incentives designed to help home owners fund their renewable energy projects.
Firstly it's necessary to explore what grants are available at the State level. If you live in a Sunbelt state such as California, Arizona, or Nevada there are many renewable energy grants and tax incentives for solar projects
Secondly, explore grants available at the Federal level. You will be able to get additional support at the Federal level regardless of where you reside in the U.S.
You should also explore group buying programs to capitalize on the many benefits they provide. There is a program available for funding solar projects in many States spearheaded by local activists who exploit group buying discounts to negotiate much better rates from suppliers and installers.
You are guaranteed to receive some government financial support when you take steps to convert to renewable energy. In most cases you will gain financially by trickling your excess solar pannel power into the mains grid during daylight down time.
Solar panel systems now have short enough pay back periods that make solar pannels a reality for thousands of people throughout the United States.
Solar Pannels - Renewable Energy
Since DIY solar pannels are at the heart of your solar residential system, more needs to be said about their importance in both solar thermal and solar electrical areas. A better understanding of how and why DIY solar pannels are both alike and different from each other would be helpful considering they are all referred to as DIY solar pannels.
Photovoltaic solar pannels will generate electrical power efficiently and provide significant monthly savings for the homeowner. Unfortunately their costs are prohibitive and payback times are greatly increased even with tax credits, generally making them a poor choice for the DIY homeowner wanting to save money.
The solar collector is somewhat different in that it absorbs solar thermal energy received from the sun. The heat transfer can take place using either the actual water itself or another transfer medium that is much like an antifreeze which will then transfer the heat to water for home use. DIY solar pannels that act as heat collectors are quite valuable in solar hot water production.
