Malaysia is the perfect place for the generation of solar power. Malaysia’s location, which is near the equator, receives between 4,000 to 5,000 Wh per square meter per day.
With its unique advantage, the solar industry in Malaysia has grown in the last years, with the creation of solar farms and other solar power companies. Solar farms in Malaysia are considered one of the most resource-efficient in the world.
Some of these solar farms produce enough energy for 1,800 houses every day.
Are you aware that there are different kinds of solar power systems? In fact, the most common types of solar energy systems for homes are grid-connected, grid-connected with energy storage, off-grid, and DC systems.
The most common type among the four is the Grid-connected system, although grid-connected with energy storage is becoming very popular despite the high cost of building it.
Let's discuss more about the different types of solar power systems.
This type of solar panel system is the most common one. It is connected to your local electric grid and your home. If your array generates more energy than what you use, it sends the excess back to the electric grid.
This way you are selling your extra solar power back to the utility company where it can be used by your neighbours or others.
This type of system requires a few panels, wiring boxes and disconnects and an inverter. Also, you have to make an interconnection agreement with the local utility company.
This type of solar power system is also known as hybrid solar. In the last couple of years, this energy system is becoming very popular, even though it’s more expensive.
It is similar to the grid-connected residential system, but comes with an energy storage system usually in the form of battery backup.
The hybrid system consists of a PV array, a charge controller, a battery bank and inverter and in some occasions a tertiary power source like a wind turbine or a gas generator.
The off-grid residential solar panel system is a lot like the hybrid system. It also uses solar panels and an energy storage system.
The off-grid system is installed in very rural, remote areas, where it is expensive to run a power line to a home.
The system is more expensive because it is bigger since it’s not connected to the electric grid. This requires more solar panels and batteries.
Should you go off-grid with solar power? Well, that depends on your main motivation.
If you want to produce your own energy, want an end to blackouts or eliminate your electricity bills, having this type of solar power may be right for you. It’s also highly suitable for those who don't have any electricity connected to their home.
But if you just want to save some money, it can be more feasible to consider a grid-tied photovoltaic system instead.
DC Solar System will power an RV or cabin, but this type of solar system doesn't typically power a whole house. It differs from grid-connected solar power system because DC solar systems don't use an inverter to convert DC electricity produced by the solar panels to the AC electricity used in most homes.
Instead, it provides electricity to DC appliances and/or a battery bank. This is the most basic type of solar power system, and it is intended to be used only when the sun shines. The system is very affordable and easy to install.
However, once the sun goes down, the power stops. It is perfect for remote locations that require low voltage. You can use this type of solar power system for certain things like:
These are the four different types of solar panel systems that are available for homes.To know which type to use for your house, review your requirements with a professional solar installer who will be more than happy to explain to you and offer you the available options.
