When you talk about solar systems, they all work on the same theoretical principle. It first captures sunlight which is then converted to Direct Current through a principle called the PV (photovoltaic) effect. This DC current is usually converted to Alternating current using an inverter and it can also be stored in a battery.
The storage of energy in battery however depends on the type of solar system you have. There are 3 main types of solar systems and we shorty discuss about each type below.
Components of a Solar System
This is obviously the most important component of a solar system. It is made up of PV cells that have the ability to generate current when sunlight interacts with it. There are 3 main types of Solar Panels: Polycrystalline, Monocrystallineand Thin Film Solar Panels.
Australia has a wide range of brands and companies specializing in solar energy. Check for the best solar panels around your area before deciding. For example, you can search for the best solar panels Tasmania to find the top-rated professionals near you.
A single solar panel is sometimes also called a solar module and combination of a two more solar modules is called a solar array.
The main product of a solar array or module is direct current. Before being used in our homes it must be converted to alternating current.
There are some systems in which the solar converter is at the end of all the solar panels. This is popular with string solar systems. Some systems have micro inverters for each panel.
Two types of batters are common with solar systems: Lithium Ion and Lead Acid.
In a normal grid-tie system after the inverter the electricity is transferred to the switchboard through which the other home appliances receiver power. This is where Net metering or Gross metering comes into play.
Type of Solar Systems
There are 3 main types of Solar Systems,
This is usually the most common type of system used by homeowners. A battery is not required by this type of system because it is directly connected to the local power grid. Any excess produced will directly go into the grid and you will be paid accordingly
As the name suggests this type of system isn’t connected to the local power grid so it needs a battery to store excess electricity produced.
This type of system is much more expensive when compared to On-Grid Systems. If you are in a rural area far from the grid, then you have no option but to opt for this type of system.
This system combines both battery storage and grid connection. This allows customers to have the best of both worlds.
This just a quick guide to introduce you to the types of systems available. Each system has its own advantage and disadvantage. Make sure to check for detailed reviews on each type of system and to also consult a professional before deciding which system suits your needs best.
