Solar energy systems can seem complicated to set up initially, however, when taken apart step-by-step they consist of various more comprehensible components. These units interact to ensure that solar power, which generates direct current (DC) energy, can be converted to alternating current (AC) energy and employed by appliances. The four main aspects of a solar energy system are solar panels, a charge controller, a power inverter, and batteries. You can buy these items and create a solar energy system for yourself, or work with a professional in order to make sure you're set up properly. It's best to get quotes from various companies before investing in a useful, but potentially pricey, solar energy system.
The foremost and most generally understood element of solar energy are solar power panels. The panels can be created out of several types of cells, and their quality varies depending on what resources are employed. However, all types of solar panels use photons produced by sunlight to generate electrical current. One solar cell only produces around half a volt of energy, but typical solar panels use thirty-six cells wired together in order to produce seventeen volts of peak output. An entire solar energy system will, of course, use more than a single panel, and hence produce plenty of electricity for a home or business.
The next aspect of a solar energy system is the charge controller. More voltage is produced when sunlight is very bright, and hence batteries need to be protected against excessive voltage created during these times. The charge controller's job is to monitor the energy produced by the solar energy system until it reaches its maximum current. It then maintains this level for a while before reducing it to a "float" level where the system will be safe.
Perhaps the most important aspect of a solar energy system is the power inverter. The power inverter is what changes DC energy to AC energy. It also charges the batteries of your system when connected to a utility grid or AC generator, if you are using a standalone system. Different types of inverters have varying efficiency levels due to the types of AC energy waves they produce. Most people end up using a modified sine wave inverter since they are a medium between the poorest functioning inverter and the priciest type.
The final part of a solar energy system is your battery, or batteries. They store electrical power so that your home or business will still have energy when the sun is not shining. Batteries can even be used for very small solar appliances, such as calculators that run on a solar powered battery. For larger systems you will want to use flooded, gel, or AGM (absorbed glass mat) batteries, though. With all of these components and the help of someone in the know - or with your own gathered resources - you will be on the way toward owning a useful and efficient alternative energy system.
