How does a solar panel installation work?

Have you ever thought about how a solar panel installation works to save you money on your energy bill?

Solar panels are a modern technology that harness the power of the sun to provide clean and renewable energy for millions of homes across Australia.

The 5 step process below will show you how valuable a solar panel installation can be for your home or business.

When purchasing a Solar panel installation, you are supplying your own electricity through the day rather than buying it from the grid. In some cases, you may not use the electricity you generate. Not to worry, this electricity is sold back to your retailer at rates up to 20c in NSW. This can create huge reductions in bills and in some cases see you even make money from your solar system.

System production is dependent on the size of your system. The more solar panels installed = the more power produced. For grid connect systems, your highest saving is calculated by your solar panel installation off-setting what your energy consumption is during the day. This is normally at a rate of around 28c per kWh. Any excess electricity produced from your solar panel installation is credited back to you by your retailer. In NSW the credit can be up to as much as 20c per kwh generated.

A solar panel installation is generally positioned on the North facing aspect of the roof with West/East as second options. Most pitched roofs are already angled for optimum efficiency. If your roof is flat, it may require a tilt frame to bring the solar panel closer to an optimum angle. Solar panels may be installed on any roof type but will require different mounting and sometimes custom work to suit the premise. Tile, Colorbond and Kliplock are most common.

Solar panels create STC’s (Small Scale Technology Certificates). Or LGC’s for large commercial scale projects. These certificates are purchased and generate a financial incentive for you to heavily subsidise the overall cost of your solar panel installation. The amount of subsidy is determined by the size of your solar system and the date that you purchase your solar. The number of STC’s generated decreases every year so there’s never been a better time to install solar panels now.

As a consumer
You should consider the following
Solar panel installation checklist below

1. The right installer

• Check social media. Look for video testimonies and photos of real installations in Australia.

• Check reviews. Multiple bad reviews generally provide a pretty good warning for companies who are being caught out and who you should avoid. Thousands of 5-star reviews are not always what they seem. There are paid services out there who provide fake reviews on the likes of Google and product reviews for bad operators.

• A licensed roofer and accredited solar electrician should be on-site during installation. This ensures your roof is protected and the electrical work is completed compliantly.

• Has the company been recognised for any awards for their service and trade? The right installer should attend the site, provide an assessment and not just a sales offer over the phone. You wouldn’t buy a new roof over the phone so why would you risk thousands of kilograms of solar product going on your roof without it being assessed first.

2. Design

• The most important part of the installation is the quality of installation, mounting and electrical. Ensure this is done by a licensed roofer and accredited electrician.

• With our in-house roofing, electrical design and installation team, you can be confident knowing that we install with the highest quality every time.

3. Inverter

• If your budget allows, consider a quality inverter. Some inverters can vary in price by over $1000. The main component of a solar system is the inverter. You can choose either string or micro inverters. String systems are more common.

• Look for local offices, good warranties, reviews and real-life examples. Micro inverters are used normally for more efficient output especially when areas of your roof may have shading.

4. Service

• Often overlooked by consumers, service is a crucial part of your solar installation. Servicing includes assisting with metering requirements, followup calls pre- and post-solar install, prompt customer attention and an onshore customer service team.

• Service is what sets apart typical sales companies and genuine solar businesses. Again, reviews often highlight the level of service your solar business will deliver every time.

5. Panels

• Solar panels generally go on the roof and simply collect sunlight to be converted into electricity. Mono-Crystalline and Poly Crystalline are the leading forms of technology in our market space. The difference is panel cost can be thousands of dollars.

• When comparing panels, warranties, history, efficiencies and where the panel is made are important factors to consider. Also, check to see if a company has a location that you can visit to make sure they are legitimate.
