"This is the second system that Adrian has installed for me... The communication was excellent both times, and all issues were dealt with brilliantly. Could not be happier with the service and quality of work and would highly recommend."


"Very happy with Thoroughtec Solar & Electrical. Customer Service was first class, and the installation process was professional and completed to a high standard. Highly recommend."


"From our first interaction with Adrian at Thoroughtec we have been impressed. He is extremely knowledgeable but also professional and genuine and was punctual when installing our solar. They were polite and worked efficiently to get the job done quickly, leaving our property spotless when they were finished."


"Adrian did an awesome job with our 6.6kW system. Extremely professional from the outset, punctual, and had great communication throughout the process. He did the extra step of running all cables through the internal wall cavity rather than just running the conduit outside the house."


"We are very happy with their work, very professional, responsive, punctual and clean. They are reachable for any questions and follow-up, great customer service. Highly recommended!"



How do solar panels work? 

Solar panels consist of photovoltaic (PV) cells that convert sunlight into direct current (DC) electricity. The DC electricity is converted into alternating current (AC) electricity through an inverter, which can be used to power electrical devices, homes and businesses.

Which solar panels are the best?

Determining the "best" solar panels depends on various factors, like your specific needs, budget, location, and preferences. We use the following well-regarded solar panel manufacturers known for their quality and performance; Trina, REC, and Jinko Solar. Any others?

What are the benefits of solar panels?

Installing solar panels offers several benefits, including reduced electricity bills, lower reliance on traditional energy sources, reduced carbon footprint, potential government incentives, increased property value, and energy independence during power outages.

How much do solar panels cost?

Financial investment depends on system size, panel quality, installation complexity, and location. As a guide, a 6.64kw system starts at $6,500 or a 10.375kw system from $10,000. Our onsite energy assessment ensures we tailor your solar system to suit your budget and electricity generation goals.

What size system will cover my electricity bill?

Designing a solar panel solution to reduce or cover your electricity bill favourably needs to factor in annual KWh, roof orientation and pitch, hours of sunlight and budget. Our consultant will advise and recommend during the initial consultation.

Is mains electricity still needed?

Solar systems only produce electricity when they are exposed to sunlight. When there is no sunlight, no electricity is produced, and you will need to draw electricity from another source, such as the grid or a storage battery. Our energy consultant will advise and recommend during the onsite energy assessment.

Can solar panels power my entire home? 

Solar panels' power output depends on system size, sunlight availability, and energy consumption. They can power a whole home, but it's typical to have a grid-connected system for drawing electricity as needed.

Do solar panels work in cloudy or cold climates? 

Solar panels can still generate electricity, but their efficiency may be reduced. Fortunately, technology has improved solar panel performance in less optimal weather conditions.

Will my solar system work during a blackout?

In a power outage, your solar system will shut down and disconnect from the grid for safety. When power is restored, it will turn on automatically. You should add a battery storage to your solar system to ensure continuous power. We can advise on this during the onsite energy assessment.

How much maintenance do solar panels require? 

Regular maintenance is crucial for your solar panel system's optimal performance and longevity. Get annual cleaning and inspections to identify potential issues. We offer yearly maintenance, or you can schedule cleaning anytime with us.
