3 Phase solar inverter

What is a 3 phase solar inverter? A 3 phase solar inverter is a device that converts Direct Current (DC) electricity generated from solar panels to Alternate Current (AC) and distributes it across a three phase power supply. 3 phase solar inverters cost more Typically, 3 phase inverters cost $300 – $500 more than a Continue reading

Solar optimisers

What are solar optimisers? Why you might want them Solar panel optimisers are devices that attach to all, or a particular panel, and allow it to function independently of every other module in the series. Solar optimisers are not a form of solar inverter. Rather, they work in tandem with a string inverter and they Continue reading

Micro inverters

What are micro inverters? How they might benefit you A micro inverter is a small solar inverter that is fitted to each solar panel, they allow the modules to operate independently of each other. If solar output is compromised by shading or soiling on one panel, only that singular module is affected and not the Continue reading

How to use solar panels

How to use your solar panels for maximum savings The best way to use solar is to run your household appliances when your solar panels are generating electricity. Ideally, you want to minimise the amount of electricity your system exports to the grid, and instead use solar energy to power your appliances directly. Minimise solar Continue reading

Solar panel efficiency

Solar panel efficiency Solar cell efficiency is the rate at which a solar panel transfers the sunlight via photovoltaics into electricity. The average cell efficiency of a solar panel is between 15 – 22%. The level of efficiency varies between manufacturers. The higher the efficiency of a solar panel, the more solar power it will Continue reading

Net metering

What is net metering? A net meter is a metering device that allows you to sell your excess solar power back to the grid in return for a financial credit. The net meter also records the electricity you buy from the grid. Solar net metering Solar net metering records your electricity imports from the grid, Continue reading

Do Solar Panels Work at Night

Do solar panels work at night? Solar panels work by converting sunlight into electricity. So, do solar panels work at night? The answer is no, they don’t produce electricity at night. However, it is possible to use the solar energy generated by your solar panels during the day, at night, using a solar system with Continue reading

Do solar panels work on cloudy days

Solar panels still work when it is cloudy Yes, solar panels work on cloudy days. However, solar output typically decreases significantly in cloudy conditions. Determining the impact overcast conditions have on the output of solar panels is difficult; as there are many different types of clouds. It is a long-maintained theory that solar panels can Continue reading

Do solar panels work in winter

Solar panels even work in winter Yes, solar panels work in winter. Solar panels work by converting sunlight into electricity, not heat. Although there are less available sunlight hours in winter months, a solar panel system can still produce electricity, albeit solar output will be lower than in summer months. The benefit of the winter Continue reading

How do solar panels work

How do solar panels work? Solar panels work by converting sunlight into electricity that you can use to power appliances in your home. The sun’s light, and not heat, generates direct current (DC), an inverter then converts the direct current into alternate current (AC) that you can use in your home to power your electrical Continue reading

Do solar panels need cleaning

Do solar panels need cleaning? Solar panels typically don’t need cleaning, rainfall is enough to free the surface of the panels of dirt and grime. The exception is for solar panels that are installed at a tilt of 10° or less, in this situation, it is recommended you clean your panels as rainfall is less Continue reading

Are solar panels worth it

Are solar panels worth it in 2022? In every Australian state, no matter your electricity consumption, solar panels are worth buying in 2022. While there are many variables that impact the cost, savings and payback of solar panels, the upshot is that in Australia they are a good investment. Typically, solar panel systems will payback Continue reading

How long do solar panels last

How long do solar panels last? Solar panels typically come with a 25-year warranty, but in reality, they will last beyond 25 years. However, solar panels degrade slightly each year and output diminishes by between 0.3 – 1.0% per year. When determining how long solar panels will last, an understanding of the degradation rate and Continue reading

Solar panel output

Photovoltaic output of solar panels Converting the rated Wattage of a solar panel into electricity to find its photovoltaic (PV) output, is essential in order to weigh up the feasibility of solar power. There are many inputs and variables required to calculate how much electricity solar panels generate; and each must be considered before the Continue reading

Solar panel temperature

The effect of temperature on solar panel performance Temperature has an effect the efficiency and maximum pv output of a solar panel. The hotter a panel gets, the less power it generates. The ambient temperature, temperature coefficient of the actual panel and the type of installation are all factors that affect the yield potential of Continue reading

Solar Panel Orientation

The effect of orientation on solar output The direction solar panels should ideally face for optimum sun exposure, varies depending on location. For Australia, solar power yields are higher when panels face north. In fact, all Southern Hemisphere locations should ideally position panels in a northerly direction. If your property is located in the Northern Continue reading

Solar Panel Angle

Solar panel angle affects performance The angle and orientation of your roof, along with the location of your property, will have an impact on how much solar power your panels can generate. Solar panels generate maximum power when they are positioned perpendicular to the sun, so that the suns rays hits the panels on a Continue reading
