The heart of your solar energy system is the inverter. Inverters convert the variable direct current (DC) output of a solar panel into alternating current (AC), which can be used to power your home or business and feed into the electricity grid.
Most systems use string-inverters but in certain situations mirco-inverters can be a better choice. Micro-inverters convert power from a single solar module, so one micro-inverter is required per panel. Whilst this makes them a more expensive option, they can be a better choice if shading is a problem on site. This is because a string inverter system… Read more
Poly-crystalline solar panels are a close cousin to mono-crystalline differing only in the way they are manufactured, in a cast rather than individual crystal ingots. These panels are blue in colour and share all the same technical aspects as mono-crystalline modules such as heat tolerance and shading. Poly-crystalline solar panels have a slightly lower efficiency… Read more
Mono-crystalline solar panels are made from purified silicon, formed into a crystal ingot and cut into round wafers, giving them a distinctive white diamond look. Mono-crystalline panels are the most efficient of all technologies, requiring much less roof space than other panels. They don’t contain heavy metals and have a proven track record within the industry,… Read more
During a power black-out your solar system will automatically shut down and disconnect itself from the grid as a safety measure. Once grid power is restored the system will then automatically turn on. If having a continuous supply of electricity is important to you, you should consider including a home battery storage system with your… Read more
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 if you have one installed.
There are a number of factors to consider when calculating the system size required to cover your electricity bill. These include your average annual kWh usage, orientation and pitch of your roof, potential shading, how much time you spend at home during the day and your eligibility for Feed-in Tariffs from your electricity supplier. Keep… Read more
The good news is that technological advances and growing demand, coupled with State government incentives such as the SA Home Battery Scheme, have made solar batteries more affordable. Prices vary depending on size, cell technology and brand but expect to pay around $9,000 for a Clean Energy Council approved product from a quality retailer.
There are a number of things to consider including budget, existing solar, energy consumption and extent you wish to be independent from the grid. It is important to have the right size solar system on your roof so you can achieve year-round performance from your battery and maximise your return on your investment. One of our… Read more
Yes AC solar batteries such as Tesla’s Powerwall 2, Alpha-ESS’s Smile and Sonnen’s Eco can all be retrofitted to any solar PV system on the market.
Simply put, it pays to store the rays! With low feed-in tariffs and high electricity prices, you should be looking to self consume as much of your solar energy as possible; and a solar battery can help you do this. Without a battery, any excess solar energy generated during the day gets fed back to… Read more
A solar battery stores electricity produced by your solar system, so you can use the energy when you need it most – either at night, on cloudy days or during power blackouts (if the battery has back-up capability).
