On grid solar energy is basically connected to the city’s electric grid. Any surplus solar energy produced by your solar energy system is then sent to the city’s utility grid. In return, you’ll receive monetary compensation from your electricity provider. But how do you start building your own solar energy system? What type of information should you be aware of before getting started?
To begin with, it’s important to understand the basic principles of a solar energy system and how it works. Your residential solar system stores energy in a battery. The battery is designed to discharge energy as soon as it is saturated. If you don’t use the battery for a long period of time, the battery won’t hold as much energy. When it does hold energy, the battery must be discharged and then recharged.
An on-grid system will have a smaller battery. It will also contain a small inverter. The solar panel contains the photovoltaic cells or PV cells that absorbs energy from photons coming from the sun. This type of energy conversion is known as solar thermal power. One of the most popular batteries is the Panasonic lithium ion battery which has a high energy density which enables it to hold enough energy to power an electric razor.
Next, you’ll need to find a supplier. There are two types of suppliers – ones that sell both types of electricity and ones that only sell one particular type. You may find a local supplier that sells both types of electricity and may be the best place to purchase your solar panels and battery. However, be careful if your locality does not have a huge electricity grid connection. You can still use this type of solar design for your on grid solar design.
The next step is to find an inverter. An inverter is used to convert the DC current from your solar panel’s direct current (DC) into alternating current (AC). The inverter will convert the AC power into direct current (DC) electricity that can be used directly by your household appliances. The benefit of having your solar panels on a grid connection is that you will have free electricity!
The last step is to connect your solar systems to an electric meter. Most solar systems will have their own meters. If yours does not, then the meter will attach to a typical electric meter and can display the amount of electricity being used in your area. A large solar system will use one meter while a small grid solar system may use two or more meters. If using electricity from the grid, the meter will show the kilowatt-hours used and will display whether the electricity is coming from the local power utility or from the solar system.
Connecting solar panels to the power grid will require an inverter and meter. Your solar panels need to be connected to an inverter which will change the DC current from your direct current (DC) power supply to alternating current (AC). The meter will measure the kilowatt-hours used and will display whether the electricity is coming from your local power utility or from your solar system.
These are the financial options for your solar panels on a grid connection. Depending on how much electricity you use and what type of solar panel you choose, it could take a few years before you begin receiving electricity from your solar panels. Do not expect to start receiving electricity from your solar panels immediately. Once the system is installed, however, you will be saving money on your electricity bill and will enjoy the freedom of no electricity cost.
