Looking for the right solar panels Gold Coast for your business or home?
In Australia, the Stand-Alone and Grid-Connect systems are the most popular. Hybrid systems are in demand too.
To make a suitable and sensible choice, first determine what type of solar panel suits your needs.
An on-grid system runs on electricity and doesn’t need battery power. During the day, the system owner uses solar energy, and at night, draws power from the electric grid. In hotter days, the system generates surplus energy which it exports back to the grid.
On-grid systems must meet utility requirements. For instance, inverters must switch off when the grid fails and not emit electrical noise that interferes with reception.
- Easy to operate
- Doesn’t need sizing to meet peak loads
- Utility companies buy surplus energy from consumers and feed it back into the grid.
- System won’t work during a power blackout
Hybrid (Grid Connected With Battery Storage)
“Hybrid” power systems are driven by wind, water and solar. But “Hybrid” solar systems are powered by electricity and batteries.
A battery backup generates power when the electric grid fails. For businesses and homes that require uninterrupted power, hybrid systems are ideal.
- Electricity is available even during a power outage
- Excess power can be sold to electricity retailers
- Users can enjoy “the best of the electric and battery worlds”
Off-grid systems are common in remote areas where electricity isn’t available. Most off-grid systems store power in batteries during periods of low-to-zero sunlight.
If the system has insufficient power, it’s advisable to connect it to a diesel generator. You can use an off-grid system for greenhouse ventilation and water pumps.
Using a generator, wind or batteries, a PV system can generate enough power even in the worst sunlight conditions. During summer, the use of the generator (as backup power) is minimal. This reduces maintenance and fuel costs.
- Is the only option where electricity isn’t available.
- Negates the need for purchasing electricity
- It’s cheaper than connecting to the grid
- Powers large appliances, water pumps and hot water systems
Portable Solar Systems
These panels are lightweight and robust. In situations where electricity is unavailable or inaccessible, a portable system is set up quickly to generate power. Such a system is suitable for farming, camping and fishing.
- Easily transportable
- Lightweight and robust
- Very reliable
- Powers USB devices, large appliances and electric generators
- Limited functions
- Isn’t suitable for commercial or large-scale residential applications
Hybrid and off-grid solar panels store energy in battery banks for later use when there’s insufficient or no power generation.
- Power is available during blackouts and periods of scant power generation
- Independence from the mains grid
- Batteries can generate additional power
Before you make a buying decision, it’s important to know what you’re getting. You want an energy-efficient system that pays dividends, not a costly system that doesn’t meet your energy needs.
