If you are planning to install a small solar panel system for your home, you must consider the different components, you can use. This is a little 'closer than you might need, like most of the solar modules will be available with a version of some of these components in the box.
Solar panels
Retail prices for single-crystal panels are about $ 6 per watt are multi-panels for $ 4.50. When it comes to solar cells, there are three basicTypes of panels are available:
Single-crystal panels are the highest quality and efficiency that work very well in conditions of semi-sun, as in coastal regions, where the number of sunny days is minimal.
Multi-crystal panels are a little 'less efficient (up to 20% less), but are also less expensive. If you live in a sunny area you could do very well with them. BP, Siemens, Astro, Evergreen, Kyocera are some of the manufacturers of both types of panels. InIn addition, Photowatt, is the only multi-crystal produces an excellent brand.
Thin-film modules, the third type of construction of the instrument panel that technology amorphous films. These dishes are much less efficient, and their life is considerably shorter. They are flexible and often find their applications on boats, cars, campers, etc. But there is no reason why you can not start here as a point of learning.
In addition to the situation in which you live, your solar power system that also determinesTablets must be purchased. Smaller plates, 50 to 100 watts at 12 volts panels come, while larger boards are usually 120-175 watts at 24 volts the panel. In the end it all depends on the combination of location, system requirements and budget.
Rack
You need to mount the disks to something that holds them in place. "Rack fixed or tracker"? is often the question. A rack fixed points of continuous sheets in the south, with the possibility of seasonal adjustment of the angleA position of the so-tracker with the sun moves from east to west to give the plates for the best contact with the light
Inverter
This device converts direct current into alternating current. It takes the protection of low voltage from the batteries and provides 110 or 220 volts AC most of the families who have to work. Two types of inverters protrude, true sine wave (TSW) and the modified sine wave (MSW) inverters. Sine Inverter provides clean electricity at a cost much higher than modified sineWave inverter. Most devices running on the MSW inverter in order.
Charge Regulators
Two species dominate the market: the multi-level monitoring and control point tracking power. The second is a PPT, which is offered through a sophisticated design, power 15-30 percent more than the previous type. The price on the PPT controller is about twice that of the multistage, then it may or may not pay for you that you have more power. The PPT-controller, the best performance in cold climatesor if the length of cable necessary additional plates from the rest of the system.
Batteries
If you need batteries for a stand-alone solar system, has become a full-size bed with a good supply of batteries for 3-5 days.
The deep-cycle lead-acid battery is the type most commonly used in a solar system. Both the gel-like type of glass mat and do not require maintenance. However, they tend to be somewhat 'sensitive and often not until the flooded lead-acid typeBattery, which requires maintenance.
Batteries come in many sizes. A very popular size is the "golf cart battery" or the T-105 type. A 6 volt 220 Ah, you must be connected in series and in parallel to provide up to 12 volts or 24 volts systems. They are relatively inexpensive and very durable and last for about 5 years.
Other considerations
Combiner and junction boxes are separated and all the essential part of any system. This can be a simple circuitThe fuse box for less than $ 100 or power panels fancy climbing several thousand dollars
In smaller systems, can be achieved with the separation of individual components. For example, monitoring devices often contain charge controllers. For separates that you can use conventional switch boxes.
