Solar power, as a feasible source of electricity, is relatively new. Scientists are still working hard to maximize the efficiency of these systems and to limit production costs. The general population is learning more about how solar energy works thanks to environmental organizations. Many have felt its potential in their own hands in the form of a calculator. Solar power is receiving more attention in the media as it becomes a viable energy source for homes. As solar energy becomes more prevalent, individual home owners are presented with the question: should I switch to solar power? The answer to this question depends, of course, on personal circumstances. Research is required, and the facts about solar energy must be considered carefully as they pertain to an individual's situation. Some benefits, for example, may apply in greater measure to people living away from main power grids. This article will explain some advantages and disadvantages of solar power and the facts about solar energy.

Solar power utilizes photovoltaic cells to produce electrical currents with the help of the sun's rays. Basically, the energy of sunlight is used to knock electrons free from a panel made of a semiconductor such as silicon. These electrons are ushered into a circuit with an electric field. From there, an inverter converts the direct current (DC) into an alternating current (AC). Appliances can then run on this AC power.

Before one addresses small-scale advantages to solar energy, consider the bigger picture. Solar power has been lauded as green energy because it does not produce harmful emissions. This is an important benefit when the alternative is burning fossil fuels. This reduction of pollution even extends to noise pollution. Solar panel systems create very little noise because they do not have moving parts. Another benefit is that it is an inexhaustible resource. As long as the sun continues to shine, it will provide clean, renewable energy.

Other benefits are more salient on an individual level. With solar power, families can attain a measure of independence from energy providers. This is especially valuable to people living in rural areas, but it can be a boon for anyone. Users of solar energy enjoy freedom from rate increases as well as other problems associated with utility companies. In this way, homeowners with solar power have a level of energy security that is difficult to find. Their energy source is guaranteed and dependable. It is also locally produced. Homeowners do not have to worry about the politics that constantly influence the price of resources like oil. Availability of solar power can also substantially increase the value of a home. Solar powered houses frequently fetch premium prices in the market thanks to the financial benefits of an installed system as well as the independence and security the system provides.

For all its benefits, it does have a major disadvantage: cost. A large initial investment is needed to install the system. This startup price is large enough that many systems do not offset their cost for a decade. In the long run, solar systems are sound investments, but it takes time before the financial windfall blows in. Of course, as the price of fossil fuel energy rises, an investment in solar power pays off sooner.

One of the main expenses is due to batteries. Since the sun is not always shining, extra energy needs to be reserved for later use. Fortunately, there is net metering offered that eliminates the dependence on batteries. If the local utility provider accepts the offer, a system is connected to the local power grid. If the home requires energy, it is purchased from the utility like usual. When the panels produce extra power, the utility company buys it in exchange for credit with the company. Since the utility provider sells the extra power to other homes for a higher price than what it paid out, the system is mutually beneficial. This is one way of limiting the cost of systems and making them pay for themselves faster. In some areas, grants can be obtained to help offset the initial installation cost. It is definitely worthwhile to research the availability of such arrangements.

If energy costs continue to rise, the solar power alternative will only look better. For now, homeowners need to consider the facts about solar energy carefully. Do the potential benefits, for your particular circumstances, outweigh the initial installation costs? In the end, each individual must answer that question for him or herself.
