Are you considering going solar in VIC, Australia? Fantastic! Solar energy is not only eco-friendly but also a great way to save on your energy bills. But wait, do you know which type of solar system is best for you? In this blog, we’ll explore the pros and cons of each type of solar system to help you make an informed decision.
Types of Solar Systems and their pros and cons:
On-Grid (or Grid-Tied) Solar Systems
- On-Grid systems are directly connected to the public electricity grid and do not have any battery storage. They use solar inverters to convert the direct current (DC) produced by solar panels into alternating current (AC) which can be used by home appliances and fed into the grid.
How it Works:
During the day, if your solar system produces more electricity than you consume, the excess is fed back into the grid.
At night or during cloudy days when the solar system isn’t producing enough electricity, you can draw power from the grid.
Advantages:
- Lower installation cost since no batteries are required.
- Potential to earn credits or money by selling excess electricity back to the grid (depending on local regulations and feed-in tariff schemes).
Disadvantages:
- The system cannot function during grid outages since it’s dependent on the grid to operate.
- Less energy independence as you still rely on the grid for power during non-sunny periods.
Off-Grid Solar Systems
- Off-Grid systems operate independently from the electricity grid. They require battery storage to store excess energy produced during the day, which can be used during the night or when solar production is low.
How it Works:
- Solar panels generate electricity during the day, powering your home and charging the battery storage.
- During the night or cloudy days, your home draws power from the batteries.
Advantages:
- Complete energy independence.
- Ideal for remote locations where connecting to the grid might be expensive or impossible.
Disadvantages:
- Higher upfront costs due to the need for battery storage and larger solar installations to ensure reliability.
- Batteries have a limited lifespan and will need replacement after a certain number of cycles.
Hybrid Solar Systems
- Hybrid systems combine the best of both on-grid and off-grid systems. They are connected to the grid and also have battery storage.
How it Works:
- When solar production exceeds consumption, excess energy can either charge the batteries or be fed back into the grid.
- During periods of low solar production, the home can use energy from the batteries or draw from the grid.
Advantages:
- Flexibility and reliability, as you can use solar energy, battery storage, or grid power based on needs and conditions.
- Potential to sell excess energy back to the grid and earn credits or money.
- Provides power backup during grid outages.
Disadvantages:
- Higher initial investment due to the combined cost of grid connection and battery storage.
- More complex systems which might require more maintenance.
