Solar electric system

In these trying times of increased economic slow down, many people are becoming more and more concerned about the high cost of electrical power usage as they look for ways to cut down on their monthly expenses. As a result, solar power usage is on the rise and more and more people are turning to it for electricity needs. Various electrical power companies are coming up with different designs so that many customers can incorporate a solar electrical system into their homes power source.
People have been harnessing the power of the sun for centuries. As time has progressed, we have learned how to create a solar electrical system for home usage as a viable alternative to relying on power companies to supply our electricity. Early solar electrical systems used to only provide heat or hot water, but nowadays we have learned how to provide electricity from a solar electrical system. Since the cost of electricity is rising at a rapid pace, not to mention becoming unreliable due to outdated power grids, a solar electrical system can provide a free and effective method to generate the electricity we need for our homes. In fact, scientists have discovered that they can measure how much power sunlight can generate. When it falls one square foot it can produce the equivalent of 1000 watts of electricity.
You will have zero running costs if you convert your home into a solar electrical system to generate electricity. A solar electrical system will be able to provide you with up to 20 years of free electricity once it is installed with major maintenance needed only after 10 years. The best thing is that your current power company may even pay you for generating surplus electricity.
Solar electrical systems types are currently categorized as:
1. grid tie
2. off the grid system / stand alone system
3. grid tie with back up battery
A grid tie solar electrical system consists of a solar panel and an inverter. The solar panel will absorb sunlight that causes a negative charge on the panel. The negative charge results in producing a direct current (DC). The inverter will convert the DC into AC power. The AC power can be used to run home appliances. If you go with this type of solar electrical system, it will supplement your electricity usage and you can greatly reduce the cost of your monthly electrical usage from the power company.
An off grid solar electrical system also has solar panels and an inverter. But it is also independent from any other power source and can work entirely under its own power that it generates. Backup batteries are used to store electricity for later use when needed. If you live in a rural area, this type is best for you.
The grid tie with battery back up solar electrical system is the most effective for use when the electrical company is experiencing a power outage. This type will produce it own power as well as be tied with the power company. Backup batteries provide power when the grid goes down. How effective a solar electrical system performs for you will depend on how many panels you have mounted and how much sun exposure the panels receive.
Solar technology commercialization has been able to bring the cost of a decent solar electrical system to within reach of homeowners. Buying a residential solar electrical system can cost thousands of dollars to have one installed, however many people are able to build one themselves and install it for a lot less. Either way, you can save thousands of dollars over the lifetime of the system.
