How do install a home PV system? This is a question always asked and concerned about by those who wish to go solar. But others think this is not a big issue because installers will help you solve the problem. My answer is you had better learn something about it.

First, you should make your self clear that your community permits this. I have heard that some communities don’t approve this. So, making sure of this will save lots of your energy.

Second, before the solar panels are transported to your home, you need a slant rooftop with an area of at least 30 square meters. The rooftop had better be a slope with a certain angle, for this is the best for absorbing sunlight. If you don’t have such a rooftop but only a flat one, you need racks to support your solar panels with such an angle. Or if you don’t think installing panels on your rooftop is possible, you can also ask the installer to install them on the ground to which you own the property right.

Third, when your panels arrive, you may pick out a spot on your rooftop or ground to install them properly. No matter whether you install them on your roof or on the ground, you should make sure they face south, east or west, so that they can catch the most sunlight and generate the most direct current.

Fourth, install some racks on your roof or on the ground to fasten solar panels. After this process you can install the panels on them in the angles that suit your local latitude condition the most.

After the installation, you may connect your panels to the solar inverter or microinverters for the sake of converting direct current into alternating current. Finally, connect your whole PV system to the local utility grid. If you are intended to do so, you may also need to install the prepared batteries into the system to satisfy the constant power supply for your house. Some who have enough financial support can connect to the grid and install batteries.

Once the installation job is over, you must be considering how to maintain it. To be honest, such a system doesn’t need too much of your time for its maintenance. You only need to make sure the panels are always clean, without anything like bird droppings, dust or snow on them. Three or four times of cleaning in a year is enough, unless you meet special extreme conditions. In addition, make sure your solar inverters are free from dust and moisture.


The Installation Process for a Residential PV System

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.
