Solar energy has been used to generate electricity in large solar power plants. As solar technology advances, even a family can generate electricity on its own by installing a small PV solar system at home. It is a new thing and so how to install it in a house still remains a mystery for many who wish to go solar. Now it is time to know how this solar power system is installed at home.
1.Search the web and learn needed information.
No mater whether you search Google, Bing or Yahoo, you had better make clear of two things: the advantages and disadvantages of generating electricity with solar energy and the requirements of installing such a home use power plant. Usually solar power generation doesn’t need biofuels like coal and gas and its costs are relatively low. But in the beginning it requires some amounts of investment. If you wish to install such a system at home, you should at least consider the amount of electricity your family consumes, where its components should be installed, function tests and so on.
2.Investigation on the spot
In common conditions the company you want to hire to do this business for you will send some of its installers to investigate your house conditions. For example, they will need to know the area of your rooftop, the shading area on it, the style of it (some are slopes and others flat), the direction your house faces and so on.
3.Making an installation plan.
By investigating your house conditions, the experts will probably need to make a plan of how to do the job for your family. Different families have different physical conditions, and so the plans will tell the house owner how the work can be done smoothly.
4.Signing a contract with the installer.
After getting the customer’s permission, the two sides need to sign an agreement to protect the profits of each other.
5.Applying for connecting to the utility grid.
You need to wait for the PV devices (including solar panels, a PV inverter, racks, wires and other components) to arrive and apply for installation and inspection by the county or the utility company. The installation usually won’t take long, and then the inspectors will inspect your system and confirm it. After everything is done, the utility company will install a new two-way meter and connects your house’s system to the grid.
6.After installation maintenance.
Usually the system is not easy to meet trouble. If something troublesome occurs, you need to call the contractor and let him do the job for you. For a common installer, this warranty will last from 5 to 25 years.
