Given all the hype about the latest solar energy and all the talk of saving our world, if you take some time for you to spend 18-33000 dollars and put solar panels on the roof. I think the time is right, because the cost is high in the last five years and gives the government that enough solar energy fell at his home become an affordable reality and make a good investment. At the same time, if many of us go this way, we can reduce our demand for foreign oil and the impact of GHG emissions in our environment.

The purchase of a solar system to produce electricity for your home to a large investment that makes most of us in life and should not be taken lightly. The same amount of money most people spend on cars, but the market is so hard, earned a bad decision. Solar energy is a little “different because it is so new and so rapid evolution of technology is easy to make mistakes is when you don’t review every purchase time.

You have the right house for solar power?

This is the first question must be answered, because many homes are good candidates for solar systems. You need space on the floor or roof, facing a breathtaking view of the sun 30 degrees south. Many houses are surrounded by trees; the cut is not the best choice. Most homes have small yards and lose their games if you installed solar panels on a table land. Photovoltaic solar panels don’t weigh much, so the roof must be sufficient, but if you have a flat roof, you need to build a structure for the panel angle to the sun.

Don’t buy more energy than you need.

This is a common mistake. You can see the electricity bills and see that your home consumes 30 kilowatts per day, if you buy a solar system, energy is sufficient to satisfy such requirements, even during the winter months to generate. By this standard for the owners buy more than two times greater than the system they need. For system connected to the network, you do not want to gain more power being used on average during the year because it will not be reimbursed by the utility to generate retail prices and may not in all. When planning a solar heating system should be the intention of producing about 80% of their annual requirements and allow the power supply provides extra power when you need it.

Their analysis of financial return.

Even if they are motivated by considerations of green, you need a good overview of the number of years to repay the initial investment. From these numbers, divide your net investment reduces the cost of the system of tax credits and rebates in annual savings for you. You should receive a response in 15/12 residential solar installations. Like most solar panels are guaranteed for 25 years and have their lives much more than that, you can expect a large amount of free electricity in your retirement.

To hire a contractor or yourself.

Most people hire a contractor because the contractor who received the skills and knowledge for the entire project, including the use of all tax credits and rebates fully eligible. In addition, the contractor is under contract with the manufacturer for warranty. This service, however, does not come with high prices. Contractor labor and overhead costs, and have an extra markup on all matters. If you are handy, you can easily manage all the equipment and the cable itself, you should hire a qualified electrician to connect the network, as is required by most of the network of electrical services and construction. If you buy more than save himself or an optional solar panels.
