SOLAR POWER OVERVIEW
A solar power system is created by integrating a number of components, including:
Solar power panels to generate the power
Solar inverter to convert the power from the solar panels into power that we can use
Mounting system to connect the panels to the roof
Cables and other components to connect the panels to the inverter and to connect the inverter to your home’s or business’s power
Monitoring devices so that we can check that the system is running as it should
Power optimisers if there is partial partial shading of the solar panels
Some systems also incorporate battery storage. Please contact us if you are considering battery storage.
Each of the above components can:
be from a different manufacturer
vary considerably in price
vary considerably in quality and performance
have a different warranty
Some companies put systems together using the same components and sell systems or a range of systems that are all the same.
Central Solar Systems uses different components to design systems that best suit a customer’s needs and budget. We don’t have any set systems. We can do this because our director is an electrical engineer and Clean Energy Council accredited designer of solar power systems. He is constantly assessing emerging solar panels, solar inverters and other system components. This allows Central Solar Systems to provide the most up to date tailored systems that will suit almost every customer’s needs and budget.
SOLAR POWER PANELS
Solar power panels turn sunlight into electricity. They are therefore placed to optimise the amount of sunlight that hits them, for example, on the roof of a home or factory.
Solar panels are therefore subjected to extreme weather conditions, including wild storms, large humidity fluctuations, large temperature fluctuations, etc. Some panels can handle these extremes much better than other panels.
Solar power panels also produce less power as they get older. Some panels produce more power than other panels over the years.
It is costly to replace solar power panels. A solid manufacturer warranty is therefore very important. It isn't uncommon for customers to be left without a warranty on their solar power panels. In 2011 there were 400 solar panel manufacturers approved to sell panels in Australia. Today the number is less than 70. That represents a lot of customers left without a panel warranty.
At Central Solar Systems we are doing our best to ensure that we offer a range of solar panels that are suitable for most budgets. We also assess other factors, including the quality of the panels, the durability of the panels (their ability to withstand extreme weather conditions for many years) and the manufacturers' local support/warranty capability.
Our range of solar power panels currently includes:
SunPower Maxeon 400W
SunPower is widely regarded as the best manufacturer of solar power panels. The SunPower Maxeon is the most efficient and most durable residential panel currently available in Australia. There is a 25 year panel warranty and a 25 year performance warranty that the panel will still be operating at 92% of it's original power at year 25.
SunPower Performance P3
The SunPower P3 is a cost effective panel which uses shingle cell technology which is very durable. SunPower holds the world patents for shingle cell technology. There is a 25 year panel warranty and a 25 year performance warranty that the panel will still be operating at 87.2% of it's original power at year 25.
SOLARWATT German Made Panels
SOLSARWATT has perfected glass on glass panel technology. This means that there is a sheet of glass on both the top and the bottom of the panel. This makes the panel extremely tough and durable. There is a 30 year panel warranty and a 30 year performance warranty that the panel will still be operating at 87% of it's original power at year 30.
Hyundai Solar Panels
Hyundai is a well known and diverse Korean manufacturer. There is a 25 year panel warranty and a 25 year performance warranty that the panel will still be operating at 84.8% of it's original power at year 25.
Phono Solar Panels
Phono is part of the Sumec group. Sumec is a large Chinese manufacturer which is the fifth fastest growing company in the world. There is a 15 year panel warranty and a 25 year performance warranty that the panel will still be operating at 80.2% of it's original power at year 25.
The solar inverter takes the power generated by the solar panels and turns this into power that we can use in the home or business, or to export to the grid. There are low cost inverters which are very basic, through to high quality inverters that are more efficient and/or may be capable of having batteries directly connected.
The term "battery ready" can be confusing. Every single solar power system with any inverter is solar ready. This is because there are battery inverter/chargers that can connect batteries to your home's power, just like a solar inverter connects solar panels. Some solar inverters have the battery charger built in, so the batteries can connect directly to the solar inverter. We will discuss this further on our Batter Storage pages.
We can help you to choose the best inverter for your needs and budget.
SOLAR MOUNTING SYSTEM
The mounting system is a very under-rated part of the system. The mounting system needs to hold the panels in place for many years, through very hot and very cold weather, cyclones, rain, etc. As with the other components there is a wide range of quality and life expectancy. We use a high quality mounting system that has been proven over many years of use.
BALANCE OF SYSTEM
A solar power system should also include high quality cables, isolators, circuit breakers, etc. We source all of our balance of system components from reputable, well known Australian based distributors.
Power optimisers are very efficient at maximising the power from a solar power system. As with micro-inverters, they allow each panel to operate individually to ensure optimum power, which is particularly important for systems that experience some shading. We use power optimisers from Tigo Energy. Tigo Power Optimisers have many benefits over micro-inverters, including: improved efficiency because there is no inverter on the roof, no capping of power at a panel level which results in greater system efficiency and the ability to use selectively. Selectively means that if 2 panels experience partial shading you only need to install 2 Tigo Optimisers. With other optimisers and with microinverters every panel must be fitted with a costly device.
Please contact us for more information.
There are many different forms of monitoring available. These can provide visibility of the following:
Power produced by the solar power system
Household/Commercial energy consumption
Power exported to the grid
Power flow to and from battery storage
We can advise on the best monitoring for your needs.
We are in the process of creating new pages which will contain valuable information on Battery Storage systems and the other components required.
