How a Solar Panel Works ?
In this page you will find what you need to know about how solar panel works.
The most known part of a solar system is the solar panel also called photovoltaic (PV) systems.
The most common system is mounted directly onto your roof, but if you do not have enough roof space, there are a lot of other ways to install a system like using structures on your garden.
The purpose of the solar panel is to capture energy from the sun and to turn this energy into electrical energy. So you produce electricity when there is sun even a cloudy days of course not as much as a summer day.
That’s why installer chooses the best option to install your system . They can choose to mounted at a fixed angle facing the south or even judge if necessary to mounted on a tracking system that follows the sun all around the day, allowing them to capture the maximum sunlight.
Your solar system can be connect to an electric utility company (grid-connected), or it’s can stand alone (off-grid). But it the last option you will have to think about battery to store the excess energy with an optional battery storage system.
A grid-connected solar panel system consumes power from the electricity provider company when your solar power system is not producing energy like in the night for example. But when the solar panels produce excess power ( during a work day or a summer day for example), the electricity provider company purchases your power.
Also called net-metering by the professional of the sector, behind this word you just have to keep in your mind that it’s the same principle of your bank account. When you are producing excess energy, you make a “deposit” in your utility company and when you can’t produce you make a “withdraw”.
So your home is still interconnected with the utility grid, and all electricity flows automatically. On sunny days, you will be feeding the grid. And at nighttime or in winter, you will be consume from the grid. Depending on the size of your system, you may even have credit at the end of the year!
You don’t need to buy battery and you are sure to have electricity in any time and you avoid all risk to be without electricity or any other trouble .
That’s why is the section Tax Credit, you will also find all rebate programs offered to you following your location. Your installer in your neighborhood should know about the requirements of each utility company each home. You can also go to our installation section to find a professional near your home.
The following description will help you to image the installation on a house.
- Solar panel: capure the sunlight to convert this sunlight to electricity. Typically installed on the roof of house but can can imagine them mounted near the house in the garden.
- Power converter ( also called inverter) the power produce by the solar panel is direct current (DC) so this device convert the power into alternating current (AC) consumed by your home.
- Electrical panel : connect to the power convert this device distribute the electricity produced across your home or back to the utility gird to get you electric credit.
- Utility meter : when your solar system produce more than you consume, the electric power flow into the gird through electric meter. Your meter will run backward, it’s means the system is creating credit with the utility company that can be consumed for future usage when your system didn’t produce electricity. This step is the net metering previously explained.
