How Solar Installers Install Solar Panels
Rooftop solar panels Newcastle are an excellent way to reduce power bills and help the environment. You can generate power for self-consumption or feed into the grid with feed-in tariffs offered by electricity retailers.
You can also go completely off-grid for total energy independence day and night. Our partners can arrange a free virtual consultation or visit your home to get you started.
Solar Panels
Two million Australian homes are now utilising solar power. This renewable energy source is becoming increasingly popular, and with good reason – it’s a sustainable, cost effective way to reduce your electricity bill.
Depending on the type of system you choose, your solar installer Newcastle can design a system that will provide most or all of your electricity needs. You can even get ground-mounted solar if you’re unable to or don’t want to install panels on your roof.
While the initial cost of a solar system can be expensive, most of our customers see a speedy return on their investment thanks to a long term reduction in their energy costs. This is especially true since NSW no longer offers a generous feed-in tariff and only some electricity retailers offer a buyback rate (although these are still very attractive). Instead, more households in Australia are relying on self-consumption and maximising their use of solar during the day.
Solar Batteries
A solar battery can provide energy storage for your rooftop solar panels, maximising the self-consumption of your own solar power and reducing your electricity bills. This is particularly important in Newcastle where the sun does not set until after 8:00pm and homes with trees can shade solar panels for a portion of the day.
Solar batteries allow your solar system to be used after sunset, on cloudy days or during a power outage. The cost of solar batteries is continuing to drop, reducing their payback periods and making them an attractive option for many homeowners.
Homeowners should note that the maximum size of a rooftop solar power system in NSW is 5 kilowatts, and that an import/export electricity meter will be required for any systems larger than this. If you are considering a large rooftop solar system, it is important to speak with your chosen installer about the feed-in tariffs and electricity prices offered by local electricity retailers.
Solar Inverters
The inverter is the heart of a solar energy system, converting DC power into AC electricity. It then feeds it into your home’s fuse box as an alternative to your electricity supplier.
Inexpensive inverters work by turning the DC side of the circuit on and off every 120 times a second, inverting it each time. This method is inefficient and loses a significant amount of energy.
String inverters are larger devices that take in DC power from multiple panels and transform it into AC energy on a single plane. They’re best for homes that have unshaded roofs. Power optimizers are individual devices attached to each panel that maximize performance and mitigate the effects of shading or mismatched panels. They’re pricier but also offer better monitoring.
Microinverters are the most efficient type of inverter but are more expensive than other types of inverters. They have a 12-year warranty or 25-year warranty depending on the model. We recommend using SolarEdge microinverters, which have a robust financial backing and provide a reliable warranty.
Solar Panel Installation
Now that all the paperwork has been filed, permits secured, and equipment purchased, it’s time to install the solar panels. This is typically the longest stage of the project. The installers will arrive at your home and prepare the work site by clearing out the area around the panels, removing decorations or furniture to make room for the construction equipment, and installing a mounting system on your rooftop or in the ground.
More experienced installers may also connect other electrical parts after the panels are mounted, and they’ll often take advantage of a rooftop’s tilt angle to optimize energy production. They’ll also check the weather forecast, as solar power systems can’t function during rainy or snowy conditions.
Upon completion of the installation, the homeowner will apply to their utility company for approval to connect the system to the grid. This process usually involves an inspection and a meter upgrade, and some utilities may charge a fee for this service. Once connected to the grid, the homeowners will begin saving money on their electricity bills.
