Adding a photovoltaic (PV) power system to a home is appealing to some homeowners but not all of the best solar panels for homes in Loomis CA are made the same. The materials from which panels are constructed add to their effectiveness and cost. Knowing what you are buying before you install a PV power system to your home can save you money up front and add to the longevity of the system.
Construction of Cells
Panels are manufactured using mono-silicon, polysilicon or thin film methods for creating electricity. Made from a single crystal of silicon, mono-silicon units are the most costly are the most efficient type of panel. Poly-silicon units are made from melting silicon crystals, are less expensive, and efficient than panels constructed with mono-silicon wafers. The third type of panel is called a thin film solar cell and is made by a co-evaporation process that uses chemicals on glass sheets. This is the least expensive and least effective method of converting sunlight into electricity.
Batteries are Important, Too
The most typical type of battery for storage has been lead acid batteries, which have been used around the globe for years to store PV energy because they are plentiful and relatively inexpensive. The least expensive electricity storage medium for your system they are not the most effective type of battery to use for long-term energy storage. The U.S. Solar Monitor Report has determined that the best method of storage is Lithium-ion batteries. They will have a higher upfront cost for your system but have a longer life and deliver more cycles per lifetime than lead-acid battery storage. Choosing the right battery for your system is as important as the panels you use.
Whose Systems are the Best?
A few companies have come to the forefront of panel development and make panels that have stood the test of time. Because after all, you want your investment to outlive the cost of the system so finding a premium product is paramount. SolarWorld makes panels that have the highest efficiency rating of any other panel, at 17.89 percent and have developed other units with ratings of 21.7 percent. Two other top manufacturers of PV panels and systems are Sanyo and Sunpower who both make high-end products. Kyocera and Sharp, both common names in electronics, make lower efficiency and lower-cost systems.
Choose your System
The cost of a PV power system will depend on the size of your home, whether you want to be fully of or on the grid, the quality of your system and whether you want to be able to power every system in the house if the power goes offline. The best solar panels for homes Loomis CA are those that are built with the highest quality materials. Choose well and your system will provide plentiful electricity for your home now and for years to come.
