Solar power utilizes the power of the sun as sunlight is transformed into electricity in a direct manner by using photovoltaics, or by indirectly using solar power that is concentrated. A concentrated solar power system uses tracking systems, lenses and mirrors that will focus a larger area of light from the sun onto a smaller area with a smaller beam. To help you understand better how a solar power system works, schedule a meeting with your local professionals like the experts at Solar Panels Brisbane.
Photovoltaics takes the sunlight and converts it into electricity using what is called the photovoltaic effect. This primarily uses photovoltaic cells are somewhat inexpensive and are used to provide electricity where power from the grid is either too expensive or not available.
The most recent trends are making solar power less expensive and more convenient, even in locations where grid power is available, solar power is used to provide low cost energy into the local grid. The one disadvantage of photo cells is the large surface area that it takes in order to gather enough sunlight over a period of time to make any kind of a difference on a larger scale. This makes solar power inconvenient at best for larger industrial applications.
Solar power for homes, however is coming more and more into the realm of practicality, as enough electricity can be generated and stored to make a fairly significant difference in the overall power bill for that particular family.
The electricity that is derived from the photo cells that are located on a roof of the home is then stored in an array of batteries, usually kept in a garage. The batteries that are available today have larger storage capacities that in previous years making the process more practical for having energy available for rainy days.
Solar power makes a lot of sense in sunny climates such as Arizona and the Southwestern states, but it can be a little more problematic in the northern states where winters see lots of cloudy days and much less sunshine. Nevertheless, the commodity of the sunshine is a “free” resource that will become more and more important as technology clears more hurdles that stand in the way of better efficiency.
There are incentives for homeowners to install solar power for all or part of their personal power grid in the way of tax credits, either with the construction of new homes, or even for installing solar power in an existing home. Financing is available for many of the systems, and a family would have to weigh the overall costs of installing such a system against staying where they are with their current system and its costs which continue to rise.
