Have you ever wondered how solar panels work? Rooftop PV systems are a great way to harness the power of the sun and convert it into electricity. They’re made up of photovoltaic cells that generate an electric current when they absorb sunlight. This is then converted into usable energy for your home or business.
In this article, you’ll find out all sorts of information on what they do, how much they cost, and why you should consider them as an alternative energy source for your home or business.
What are solar panels made of?
They are made from several different materials, the most common material being silicon, which makes up about 90 per cent of the cost for a typical panel. Other materials include glass, aluminium and copper.
Silicon is a common material used in many things like computers, cell phones, and even glass. Solar panels use silicon because of their ability to absorb sunlight to create electricity.
How solar cells convert sunlight into electricity
Solar panels are made up of photovoltaic cells that convert sunlight into DC electricity; the same type of electricity is used in your home or business. DC electricity flows in one direction around a circuit; this is different to AC (alternating current) which changes direction 50 times per second.
AC energy powers our homes and businesses, but we need to convert DC into AC before it can be used for anything else. We do this with an inverter – these clever devices change DC voltage levels, so they match those required by household appliances like microwaves or televisions.
Solar inverters are the brains of the operation. Along with converting DC to AC, they also provide ground fault protection and system stats, including voltage and current on both circuits, energy production, and maximum power point tracking (to maximise power extraction under all conditions).
How much does it cost to install a solar system?
The price of installing solar power varies depending on the size, type and location. The good news is that the cost of these renewable technologies has come right down.
Solar panels are almost 82 per cent cheaper than they were a decade ago, while the technology has improved and efficiency rates have risen to over 25 per cent. Many government rebates are available to reduce out-of-pocket expenses, and Energy matters can connect you to the best systems at the most affordable prices.
We stock various panels, including the German-engineered excellence from the Aleo Solar range, which includes 25-year product and performance guarantees. You can even take solar solutions on the road with you.
Portable energy solutions have become highly accessible. We also stock Renogy 100 Watt 12 Volt Extremely Flexible Monocrystalline Solar Panels that will easily mould to your caravan or RV or roll up for easy transport when you hit the road.
