FAQs

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.

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.

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.

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.

Quality solar panels typically last 25–30 years. Regular cleaning and professional inspections help maintain their efficiency and warranty.

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.

Yes. With the right battery capacity and design, off-grid systems can power homes, farms, and businesses completely independently, even during extended cloudy periods.

Batteries store excess energy from sunny days to supply power when sunlight is low. A backup generator can provide additional support if needed.

Regular maintenance involves checking connections, cleaning panels, and monitoring battery health. Many modern systems can be monitored remotely for convenience.

Yes. Most RPC systems come with smart monitoring apps that let you track production, storage, and consumption in real time.

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.

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.

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.

Standard grid systems shut down during blackouts for safety. Hybrid systems with batteries can keep key appliances running using stored energy.

The NSW Government offers up to 30% off the cost of adding a battery, and most systems qualify for federal STC rebates.

Feed-in tariffs pay you for excess electricity exported to the grid. Rates vary by provider, usually 5–10¢/kWh.

Yes. Additional panels or batteries can often be added, depending on your roof space and inverter capacity.

Most lithium batteries last 10–15 years depending on use and maintenance. Proper charging and temperature management help extend lifespan.

Lithium batteries are the most efficient and reliable option for most homes. They’re lightweight, long-lasting, and require little maintenance.

No. Modern lithium batteries perform best when partially discharged and recharged regularly.

Keep batteries in a cool, dry location and ensure proper ventilation. RPC configures systems for optimal charging and performance.

It’s not recommended. Used batteries often have reduced capacity and shorter lifespans, leading to unreliable performance.

All RPC systems are installed by licensed electricians and accredited solar professionals to meet Australian standards.

Most residential systems are installed within 1–2 days once approvals are complete. Larger or off-grid projects may take several weeks.

Yes. RPC supplies and supports systems nationwide and partners with certified installers in regional and international locations.

We provide ongoing technical support, monitoring setup, and maintenance advice. Our team is always available for troubleshooting.

Use your inverter display or app to check output. If you notice unusual drops, contact RPC for help.

We recommend a professional inspection every 2 years to ensure safety, performance, and warranty compliance.
