FAQs
What’s the difference between on-grid, off-grid, and hybrid systems?
On-grid systems are connected to the mains electricity network, letting you sell excess energy back to the grid. Off-grid systems operate independently using batteries for 24/7 power, ideal for remote properties. Hybrid systems combine both, you stay connected to the grid while storing extra solar energy for backup and savings.
How do solar panels work?
Solar panels convert sunlight into direct current (DC) electricity. This is then converted into alternating current (AC) by an inverter so it can power your home or business. Any surplus energy can be stored in batteries or exported to the grid.
How much can I save with solar?
Savings depend on system size, energy usage, and location. Most homeowners reduce their electricity bills by 50–80%. A typical 6.6kW system can pay for itself in 3–5 years.
What size solar system do I need?
The right size depends on your average energy use and roof space. A 5kW system suits smaller homes, 10kW for larger homes, and 15kW+ for properties with higher energy demands.
How long do solar panels last?
Quality solar panels typically last 25–30 years. Regular cleaning and professional inspections help maintain their efficiency and warranty.
What is an off-grid solar system?
An off-grid system generates and stores its own power without relying on the electricity grid. It uses solar panels, batteries, and inverters to supply continuous power day and night.
Can I power my whole home off-grid?
Yes. With the right battery capacity and design, off-grid systems can power homes, farms, and businesses completely independently, even during extended cloudy periods.
What happens during cloudy weather or long nights?
Batteries store excess energy from sunny days to supply power when sunlight is low. A backup generator can provide additional support if needed.
How are off-grid systems maintained?
Regular maintenance involves checking connections, cleaning panels, and monitoring battery health. Many modern systems can be monitored remotely for convenience.
Can I monitor my off-grid system remotely?
Yes. Most RPC systems come with smart monitoring apps that let you track production, storage, and consumption in real time.
How do I choose the right battery bank?
The right battery depends on your energy usage and how many days of autonomy you need. RPC designs each system to suit your load profile, location, and lifestyle.
How does a grid-connected solar system work?
Grid-connected systems send solar power directly into your home or business. When solar production exceeds usage, the extra energy is exported to the grid for a feed-in credit.
What is a hybrid system?
Hybrid systems combine solar and battery storage while staying connected to the grid. They allow you to store power for later use and still access grid power when needed.
Will I still have power during a blackout?
Standard grid systems shut down during blackouts for safety. Hybrid systems with batteries can keep key appliances running using stored energy.
What government rebates are available?
The NSW Government offers up to 30% off the cost of adding a battery, and most systems qualify for federal STC rebates.
How do feed-in tariffs work?
Feed-in tariffs pay you for excess electricity exported to the grid. Rates vary by provider, usually 5–10¢/kWh.
Can I expand my solar system later?
Yes. Additional panels or batteries can often be added, depending on your roof space and inverter capacity.
How long do solar batteries last?
Most lithium batteries last 10–15 years depending on use and maintenance. Proper charging and temperature management help extend lifespan.
What type of battery is best for my system?
Lithium batteries are the most efficient and reliable option for most homes. They’re lightweight, long-lasting, and require little maintenance.
Do I need to fully discharge my batteries?
No. Modern lithium batteries perform best when partially discharged and recharged regularly.
How can I extend battery lifespan?
Keep batteries in a cool, dry location and ensure proper ventilation. RPC configures systems for optimal charging and performance.
Can I use second-hand or recycled batteries?
It’s not recommended. Used batteries often have reduced capacity and shorter lifespans, leading to unreliable performance.
Who installs RPC systems?
All RPC systems are installed by licensed electricians and accredited solar professionals to meet Australian standards.
How long does installation take?
Most residential systems are installed within 1–2 days once approvals are complete. Larger or off-grid projects may take several weeks.
Do you offer installation outside NSW or QLD?
Yes. RPC supplies and supports systems nationwide and partners with certified installers in regional and international locations.
What after-sales support do you provide?
We provide ongoing technical support, monitoring setup, and maintenance advice. Our team is always available for troubleshooting.
How do I check if my system is performing properly?
Use your inverter display or app to check output. If you notice unusual drops, contact RPC for help.
How often should my system be serviced?
I am a so called subtitle.We recommend a professional inspection every 2 years to ensure safety, performance, and warranty compliance.
