Solar energy has taken the world by storm, transforming the way we think about power and sustainability. Beyond its environmental benefits, there are countless intriguing aspects of solar power that make it a standout energy source. Let’s dive into 10 fascinating facts about solar energy and uncover why it’s considered the energy of the future.
1. Solar Energy is Abundant
The sun produces enough energy every hour to meet the world’s electricity needs for an entire year. This virtually limitless supply makes solar energy one of the most promising solutions to global energy demands.
By investing in solar panels, households can tap into this abundance and significantly cut down on electricity bills.
Solar efficiency plays a big part in how much of this abundant energy is converted into electricity. The average efficiency of a solar cell these days is around 20%. That number is increasing all the time. But there are many other factors that come into play when determining how much sunlight your system converts into power. These including placement, shading, temperature and the other elements of your system, the inverter for example. Our goal is always to give you a cost-efficient way to convert this abundant sunlight to fulfil your home’s energy needs. Talk to us about the right solution for your home.
2. Solar Panels Work Even on Cloudy Days
Contrary to popular belief, solar panels don’t need direct sunlight to generate electricity. They work efficiently on cloudy days, converting diffuse sunlight into power.
It’s important to note that there are no absolutes when it comes to clouds and solar power generation. The type of cloud, for instance, can have an enormous impact on whether your solar system’s output during cloudy days. High clouds effect solar the least, with mid level and then low level having the biggest impact. High level cloud has very little impact on your solar. That said, one study, Effect of cloudiness on the production of electricity by photovoltaic panels, concluded that ” it is impossible to determine the effect of different types of clouds on electricity production of photovoltaic panels”.

3. It’s the Fastest-Growing Energy Source
Solar energy is now the fastest-growing source of electricity worldwide. According to the International Energy Agency, global solar capacity is expected to quadruple by 2030.

In 2023, solar PV alone accounted for three-quarters of renewable capacity additions worldwide.

4. Solar Panels Can Last Over 25 Years
Solar panels are built to last, with most systems offering a warranty of 25 years or more. Even after their warranty period, many panels continue to produce electricity at reduced efficiency.
Industry Insider Tip: Regular maintenance can extend the lifespan of your solar panels and ensure peak performance.
5. Solar Energy is Ancient
Humans have used solar power for centuries. Ancient Greeks and Romans used passive solar design to heat their homes, a precursor to modern solar technology. Socrates lead seminars on building to maximise solar potential.
6. Australia is a Solar Powerhouse
Australia has one of the highest uptakes of solar energy in the world, with over 3 million solar systems installed across the country.
Australia’s 45TWh of solar is eclipse by China’s 548TWh but they do of course have a considerably larger population. Australia has massive solar potential, one of the highest in the world. As shown in the map below. With this potential we should be able to maintain our growth of solar capacity for many years.
8. It’s Becoming Cheaper
The cost of solar energy has dropped by more than 80% over the past decade, making it more accessible than ever before.
9. Solar Energy Saves Water
Unlike traditional power plants, solar energy systems require little to no water to operate, making them a water-efficient alternative. According to a the University of Adelaide, NSW and Queensland coal-fired power stations annually consume 158,300 megalitres of water. And that’s not accounting for the mining of coal, which also requires a lot of water. We’re in the middle of a nuclear debate in Australia so it is worth nothing that nuclear power generation uses a fair bit more water than coal.
Enough water for nuclear reactors in NSW but scientists worry about wildlife.
10. It’s Not Just for Electricity
Solar energy can be used for heating, desalination, and even to produce clean drinking water in remote areas using solar stills. Solar hot water systems are a common site on Australian roofs.
Solar energy is more than a clean power source; it’s a revolutionary technology shaping a sustainable future. Whether you’re looking to save on energy bills, reduce your carbon footprint, or explore innovative uses, solar energy has something for everyone.
