Solar FAQs

Solar panels reduce the amount of electricity you buy from the grid by generating power for your home. Your savings depend on your system size, electricity usage, solar generation, electricity rates and how much solar energy you use directly. A site-specific system design gives you a more realistic estimate of potential savings.

The right solar system size depends on your electricity consumption, roof space, roof orientation, shading and future energy needs. Smart House Solar reviews your energy usage and property before recommending a system size, rather than simply selling the largest available system.

Compare the complete system, not just the advertised price. Check the panel and inverter models, system size, estimated energy generation, warranties, installation inclusions, accreditation, export limitations and after-sales support. A detailed quote should clearly explain what you are paying for.

Eligible solar systems receive support through the Small-scale Renewable Energy Scheme (SRES), with Small-scale Technology Certificates (STCs) reducing the upfront cost of eligible installations. Eligible home batteries also receive incentives under the current Cheaper Home Batteries Program, subject to program requirements.

A solar battery stores excess solar energy generated during the day for use when your panels are producing less power. This increases your use of solar energy and reduces your reliance on grid electricity. Battery value depends on your electricity usage, solar generation, tariffs, battery cost and storage capacity.

The right battery size depends on how much electricity your home uses, how much excess solar your system produces and when you use electricity. A properly sized battery matches your energy habits instead of simply choosing the largest capacity available.

Yes, many existing solar systems can be upgraded with battery storage. Your existing inverter, system configuration, switchboard and battery compatibility need to be checked first. Smart House Solar can assess your current solar system and recommend the appropriate battery configuration.

A standard grid-connected solar system shuts down during a power outage for safety reasons. Solar panels alone therefore do not provide normal household power during a blackout. A compatible battery and backup system provides power during an outage when the system is designed and configured for backup operation.

Your home uses the solar electricity it needs first. When your system produces more electricity than your home is using, the excess electricity is exported to the grid, subject to your network and system configuration. Your electricity retailer then applies the applicable feed-in tariff to eligible exports.

Yes, an existing solar system can often be expanded, but the inverter capacity, existing panels, roof space, electrical configuration and network requirements need to be assessed first. Adding panels is not simply a matter of filling unused roof space; the complete system must remain compatible and compliant.

Look for an installer with appropriate accreditation, qualified electricians, quality products, clear warranties, transparent quotes and strong after-sales support. Smart House Solar uses SAA Accredited electricians and CEC-approved products, with solar, battery and EV charging solutions tailored to residential and commercial customers.

A straightforward residential solar installation can often be completed in a day. The actual timeframe depends on system size, roof type, accessibility, electrical work and whether battery or EV charging equipment is included. Smart House Solar confirms the installation requirements before the installation begins.

Quality solar panels are designed for long-term operation, with manufacturers commonly providing long performance warranties. Actual system life depends on product quality, installation, environmental conditions and maintenance. Solar panels should also be monitored periodically to identify performance issues early.

Yes. Smart House Solar provides solar systems, solar battery storage and EV charger installation for residential and commercial customers. Its current service offering includes complete solar and battery solutions as well as EV charging installations.
