High efficiency solar panels are available in varying levels of effectiveness, though most boards are capable of producing 11 to 15 percent of the overall energy they absorb. With high efficiency solar panels, less surface area is required to generate the amount of energy needed to power a household or a small business. As a result, a customer may purchase fewer units to power their home, which saves on both money and space. Some cells can convert up to 19 percent of what they absorb into workable electricity. They are an ideal choice for smaller buildings that don’t have much room for a large system. Many buildings may be fully powered with 10 to 20 arrays up and running, negating the need to be dependent on the local utility company.
The system’s output is dependent upon several factors. It must be installed at just the right angle, or solar latitude, to optimize the amount of sunlight that strikes the cells. This can be a tricky task as the roofing it sits on is also angled, and if not handled properly, this can modify the amount of sunlight the high efficiency solar panels receive every day. The array must be installed with ample space between the roof and the bottom of the system. This space cushion helps regulate temperature and reduce the likelihood of heat damage to the roof or the system itself. Some models may also be disrupted by the presence of shadows, so this also must be taken into account prior to the installation.
Arrays are available in two basic types: monocrystalline and polycrystalline silicon. Monocrystalline high efficiency solar panels utilize a single cell, and will produce somewhere around 17 to 19 percent efficiency. It is the most productive type of cell, and can absorb more light energy than other models that are available. A polycrystalline silicon board is made up of multiple cells that are embedded with lower amounts of silicone. It is more affordable but slightly less effective than the monocrystalline options. A homeowner can maximize their savings by figuring out what the exact energy needs of the home are prior to making a purchase. This will be easier by contacting a professional that can assess the home and the appliances to get the best estimate of the power needed on a daily basis.
Most customers switch to this alternative energy for the advantages of solar power opposed to other sources. They may be eager to save money, as installation and material costs are the only fees involved when installing an array. They may want to help out the environment by utilizing a green source of power. They may want to increase the property value of their home. They may be looking to turn a profit by selling excess energy back to the utility company. There are many benefits, incentives and government programs to help lessen the financial blow of switching over even further.
Though systems will vary in their effectiveness, high efficiency solar panels can power a building without costing a fortune. The arrays create energy from a renewable source, and many clients enjoy going green and reducing airborne pollution.
