How Solar Panels Work
Solar Panels Work By
Capturing sunlight and turning it into electricity right from your roof. Each panel is made up of solar cells that absorb light from the sun. When sunlight hits the cells, it knocks electrons loose, creating a flow of electricity.
This clean, renewable energy is then sent through an inverter, which converts it into power you can use in your home or business. Any extra energy can be stored in a battery or sent back to the grid
Frequently Asked Questions
Solar energy reduces your power bills, protects you from rising electricity prices, increases the value of your home, and lowers your environmental footprint. It’s a smart investment that pays for itself over time.
Solar panels convert sunlight into electricity. This power is first used in your home, with any excess exported back to the grid or stored in a battery for later use.
Yes most households save significantly on their power bills. The exact savings depend on your energy usage, panel size, and whether you add a battery, but many systems pay for themselves within 6–9 years.
Every property is different, but as a guide, a typical home system starts from around $10,000 installed. Adding a battery increases the cost but also increases your independence from the grid.
Not necessarily. Solar works without a battery, but adding one lets you store excess energy to use at night or during a power cut. Popular options like Sigenergy and Tesla Powerwall 3 come with a 10-year warranty and provide reliable backup power.
Solar panels are usually installed on your roof, ideally facing north for maximum sun exposure. East- and west-facing roofs also work well, and flat roofs can be fitted with tilt frames to optimise the angle.
At night or on cloudy days, your home simply draws power from the grid (or from your battery if you have one). Solar panels still generate some electricity in winter and on overcast days, though production is reduced.Content
Yes excess solar power can be diverted to heat your water. You can also combine your solar with a hot water heat pump for maximum efficiency, which we often recommend for households wanting the best energy savings.
High-quality solar panels, like the Trina Tier 1 panels we use, are designed to last 25+ years. Inverters and batteries usually need replacing after 10 years or so.

Posted on Maryanne and GrahamTrustindex verifies that the original source of the review is Google. Ecoefficient were great to deal with. The staff were all courteous, respected our property and did a professional, tidy job. Laura and Rachel kept us up to date with when the job would begin and days the boys would be on site. We have a passive house constructed with SIPs. Shaun, Tim and the team took the time to learn how to maintain the integrity of a passive building and we are very pleased with the end result. We are enjoying looking at the app to see how well our solar system is performing and how much change there is to our power bill. We also installed an EV fast charger. It is easy to control the charger with the app so we can maximise our solar power remotely.Posted on Viv MouleTrustindex verifies that the original source of the review is Google. Easy to understand pre installation information. Excellent communication throughout the installation process. Very pleased with product and impact on winter power bill.Posted on Matthew HardyTrustindex verifies that the original source of the review is Google. Ecoefficient operate a highly professional and service-oriented company, delivering a seamless and hassle-free experience. I’m extremely pleased with our decision to work with them. As someone who is detail-focused and asked numerous questions throughout the process, I consistently received prompt, honest, and well-considered advice. I would not hesitate to recommend Ecoefficient to anyone considering a solar installation. After conducting thorough research, I can confidently say they stand out in the industry.Posted on Jonathan “Jon” FeyTrustindex verifies that the original source of the review is Google. Shaun and the whole team were excellent to deal with. From the quote process that was professional and informative without pushy sales tactics, to the planning and install everything was very good. We had a few hicups with some pre installment work due to other trades but the team helped get this sorted as well. The install was excellent with attention to detail and all aspects were considered to ensure a very clean and ordered finish. Highly recommend Ecoefficient SolutionsPosted on David NapierTrustindex verifies that the original source of the review is Google. After having exhaustively research solar installers, Ecoefficient came out tops for hardware and installation. Their communication is second to none and the fantastic team who turned up to do the job, worked like a well oiled machine, despite the bad weather. Since installation, inspection and commissioning, I am absolutely stoked with my decision to go with Ecoefficient and could not more highly recommend their professionalism and expertise.Posted on Lena WhettonTrustindex verifies that the original source of the review is Google. Had a great experience using Eco Efficient Solutions. Great communication and always happy to answer questions. Would definitely recommend this company. Thanks for our awesome solar system.Posted on Matt BarclayTrustindex verifies that the original source of the review is Google. Three years on from having my off-grid system installed by Ecoefficient, I’m still impressed with their ongoing support. When my system needed a software upgrade, the team’s service was as exceptional as it was the day I first bought it. Recently, as my power needs grew, they were incredibly helpful with my battery storage upgrade. Their strong relationships with international suppliers give me confidence that I’m getting the best of both worlds—local, personalized service backed by international expertise. Living off-grid has shown me just how vital it is to have a supplier that genuinely cares and provides top-notch support. Ecoefficient absolutely delivers on that, and most importantly, I haven’t had a single day without electricity since my system was installed.Posted on Colleen McCreeryTrustindex verifies that the original source of the review is Google. Really fantastic experience with Ecoefficient Solutions. They did a great job quickly sorting and installing our solar panels and provided responsive follow up afterwards. Highly recommend.Posted on Wayne LeadbetterTrustindex verifies that the original source of the review is Google. Good people - great service. For us they have added more panels plus a Powerwall to their initial panel installation. Work is done well in line with expectations advised ahead of the installation - and the team are a pleasure to work with.Posted on Jason IronsTrustindex verifies that the original source of the review is Google. Had a fantastic experience with Ecoefficient Solutions. From design to build and after implementation support, Laura, Anna and the team have been extremely supportive and engaging at every step. The end result was a Solar array which performed far better than I expected. Along with freedom and independence from the grid, no more power blackouts (happens a lot where I am) and huge cost savings. Thanks team :-)
