People often have questions in their minds: What is an Off-Grid System comprised of?
In general, five components work together to create an efficient off-grid solar
system.
So, here we’ve listed everything you need for an off-grid setup in Australia:
- Solar Panels
Solar panels, also known as PV modules, are one of the main components for capturing sunlight and generating
direct
current.
The amount of sunlight the panels can capture and effectively convert into electricity depends on several
factors,
including module quality, quantity, exposure
to
sunlight, roof angle, and geographical location.
- Solar Inverters
The primary task of a solar inverter is to convert the electricity generated by the solar panels into usable
energy.
The solar
panels generated electricity in the DC format, and that remains unusable until it’s run
through the
solar inverter. Inverters convert DC into AC (alternating current) for the appliances to use and
operate.
There are many types of solar inverters, some of which are even capable of storing energy for later use.
Inverter types can be:
- Pure sine wave, which offers clean and stable power that is safer for sensitive electronics.
- Modified sine wave inverters are cheaper but less compatible with some devices.
Solar Battery Storage
Solar panels are designed to operate using the power of the sun. Still, for a majority of the households in
Australia, electricity is most needed in the evening hours or at night.
So, how can we store solar power for nighttime use? Can solar batteries make off-grid living more viable?
To store the surplus of energy generated during peak hours, you will need solar
batteries.
It’s an essential component for an off-grid solar system.
Modern houses and businesses typically use deep-cycle batteries, such as Lead-acid (flooded or sealed
AGM/Gel) and Lithium-Ion.
They are
more efficient and long-lasting, but can cost more than the traditional ones.
Solar Charge Controller
It’s not a feasible arrangement if you always have to manage the energy flow in the correct direction. To
address
this, a charge controller is necessary.
It controls the direction of energy flow to the proper path according to the situation and prevents the solar batteries from overcharging, essentially
extending their life.
Backup Generator (Optional)
If all things go south, a diesel-powered backup generator will come to your rescue.
It is not an everyday event with a quality system, but on the off chance you do experience a power outage through
solar. There could also be extreme weather events, so it’s best to have an off-grid solar panel system with a
backup generator.
