Solar Energy Reviews

Solar panels are devices that convert light into electricity. Solar panels are getting cheaper, but still not cheap, so if you are switching to solar is a good time to also carefully evaluate the use of electricity. Call your utility company and get an "audit energy "and follow the recommendations. Most homeowners can reduce the use of electricity or gas by anywhere from 5% to 30%. By reducing the use of power to an absolute minimum you can buy only the expensive solar panel capacity that is required for your home. PV (photovoltaic), solar panels are made solar cell is a semiconductor material.

Electricity

The process to create electricity from sunlight is quite complex, but all you need to know is that the photons collide with electrons in the semiconductor material and essentially free of them until the flow when connected to a battery. This flow of electrons is what makes an electric current.

The average household uses of electricity per day 30kwh. The utilities are required by law to include "net metering". This means you can sell your surplus energy to the energy company. So, if they work outdoors on a sunny day, or go on vacation for two weeks of skiing and are not using electricity, the power to be created by the solar panels is returning to grill to the utility. In other words, every kilowatt hour of electricity produced by a solar energy system ends up being used to the advantage of the homeowner, either as the power to run appliances when the homeowner is there or as a dollar for dollar credit provided by the utility for power not being used.

Cost

The most important component of the solar PV system will probably the amount of grant you are eligible. Because some utility companies must comply with the goals of the amount of renewable energy they supply, There are some very attractive discounts offered sometimes. These discounts can be very large indeed, up to 50% of the cost of a system or even higher. This can make a system that support to the average of 30 kWh per day for about $ 20,000 startup cost instead of $ 40,000! In addition, a $ 2000 tax credit offered by the federal government. However, this is not always the case. In our local area of Colorado, there are several utilities that service region. One offers a discount of 50% described above. Another offers a 66% discount, and a third does not offer discounts to all. So you have to check with your utility company to see what discounts in appropriate, apply to your location. You should also contact a contractor for solar panels that can give much information about system costs, and of course that probably know the discounts offered in your local area. Typical photovoltaic solar panels will cost about $ 4 per watt before installation. Installation is a major expense, however, in the above example, with a 50% discount, end system costs amount to about $ 6.50-$ 7.00 per watt installed.

Batteries

Batteries are necessary in the autonomous systems to provide energy during the night. These can be very expensive, but if you have an isolated hut, an RV, or some other need for power and have no access to the utility grid, a solar system with batteries is certainly a solution.

Conclusion

In considering the costs of a full blown solar PV system, reducing their electricity bill to zero or close to it, you get benefit of others. The value of your property increases such a system, and property taxes will not increase because of this added value. Besides the satisfaction of harvesting of their carbon footprint significantly, the system eventually pay for itself and its property will be worth more too. Consider these factors when calculate the payback period.
