Frequently Asked Questions

1. Why install solar panels?

Solar panels reduce a household’s electricity bills and carbon footprint. Solar systems also increase the value and energy rating of your house.
Photovoltaic (PV) systems use cells to convert solar radiation into electricity. The cell consists of a semiconducting material. When sunlight hits the cell, it creates an electric field across the layers, causing electricity to flow.
A solar PV system which is connected to the local electricity grid using a Smart meter. Electricity can then either be fed into your home as per normal when your demand is exceeding the solar system’s ability to generate (or at night time), or it can be fed back into the electricity grid if you are generating more than you are consuming.

Export limiting is determined by your local electricity network operator and involves using additional hardware to “throttle” the inverter output if certain solar export limits are reached, typically around 5kW. To learn more about how Export Limiting works read this article.

Solar PV systems rely on sunlight and ultra violet (UV) rays, not heat. So, while there may be fewer hours of sunlight in winter, the actual conversion of power is unaffected by the change in climate. You will, however, benefit from the extended hours of sunlight in the summer.

Yes. When your household consumption exceeds the production capability of the solar + battery system, excess electricity from the the grid will be imported to your home.

Refer to the following article to help answer some of the most common causes that see power bills go up even after solar has been installed.

By storing energy, you can use it more efficiently by avoiding the grid during peak times when energy is more expensive, which improves energy savings. You can also continue to have power in the event of a blackout.

Solar photovoltaic panels require sunlight to produce solar electricity. Your supplier (the grid) will continue to supply your electricity at night.

All RESINC solar + battery systems come with blackout protection so if there is a power outage, at CT sensor will activate the Energy Management System (EMS) in the inverter which will activate the emergency power supply (EPS) in the battery system so energy in the batteries can continue to power your home. If you do not have batteries installed your solar electricity system will shut down until utility power returns.

single-phasethree-phaseThe short answer is, yes, it is possible to install a single phase inverter on a three phase property. Check out this article for a more detailed explanation

The amount of solar electricity produced by your panels is determined by the amount of sunlight available. Solar systems can still generate around 50% of their peak output under overcast conditions but heavy clouds that significantly reduce brightness during the day will further reduce performance.

Oversizing is when you install more solar panel capacity than your inverter’s AC output. It is very common in solar installations helping to improve overall production and maximise the output of your inverter. To dive deeper into this topic, read more here.

Because your solar panels may not produce enough electricity to supply your household’s electricity needs every day. Solar systems only generate power when the sun is shining so you will the grid to supply electricity when the sun is not shining, or consider a battery solution.

Most PV systems can be upgraded with additional solar panels. If you wish to increase your solar system significantly at a later date, it is better to install a larger inverter now with the capacity for more panels.

To use as much of your generated solar power as possible, monitor your electricity use by programming your appliance and checking it. This especially goes for electricity-intensive items like your dishwasher, washing machine, dryer and even your electric hot water system.

High quality solar panels can last well over 25 years. However, the inverter will typically have to be replaced during this time period, depending on the quality.

Once the system has been installed there is little ongoing maintenance that is required. The only item that may need attention, depending on the installation, ​is to clean the solar panels with water.

Yes. All solar photovoltaic panels have been extensively tested and will withstand a 25mm hailstone at terminal velocity. Hail damage is more likely to affect roof tiles than solar panels!

All RESINC Solar panels have a manufacturer’s warranty of 10 years and a performance warranty of 25 years.

Properly installed PV systems are covered by most insurance policies in the same way as any other electrical equipment installed on the insured property, but the individual policy should be consulted to determine the limits of coverage.

Our aim is to install between 2 – 8 weeks depending on finance and grid approvals for your system and co-ordination of a date suitable for both yourself and the local install team.

It usually takes about 1 day for two accredited installers to fully install a 5kW system – depending on weather, system size, roof type, roof area and height.

Over 15 years industry experience and all installers must not only be qualified electricians but must also have Solar Power Grid Connect Photovoltaic System qualifications endorsed by the Clean Energy Council.

There is no defined maximum. Any WiFi connection is subject to range restrictions – and these can be influenced by a variety of external factors. To test whether WiFi connectivity will be possible prior to install, try standing in the location where the inverter will be installed and use a smart phone to see if it can see the customer’s WiFi signal (but this is not a guarantee and should only be used as a guide).

No, however, if the inverter has an internal WiFi adapter, it will be replaced under the exchange programme if it is proven that the WiFi adapter is faulty. If the inverter is emitting a WiFi signal but no data is being received to the cloud, then this will fall outside the terms of the warranty. The WiFi connectivity is subject to external factors such as range and relies on the correct configuration of third-party devices such as routers, factors that are beyond the control of SolaX. Our latest product range is supplied with an external ‘plug & play’ WiFi adapter which will be replaced under warranty if proved to be faulty.

It’s a feature designed to detect whether a wireless client is capable of operating on both 2.4 GHz and 5 GHz networks. If so, it pushes them towards the less congested 5 GHz network. While this offers flexibility for modems, it becomes problematic for inverters, which can only connect to 2.4 GHz networks. Modems may misidentify inverters as dual-band capable and attempt to shift them to the 5 GHz network, thereby preventing connection to the modem.

One method is to check your Wi-Fi settings on your phone or laptop within range of your home Wi-Fi. If band steering is disabled, you should see both your home network and its 5 GHz version listed. Another option is to utilize Wi-Fi analyzer apps available for smartphones or to check Wi-Fi connection properties on Windows.

If you can’t find the 5 GHz network, it’s likely band steering is causing the problem. Changing these settings varies depending on your modem but is typically done through your modem’s settings portal on your PC or laptop. Consult your modem’s manual or contact your internet service provider for guidance. Note that band steering issues have been observed in modems from Telstra, Optus, Huawei, TP-Link, and potentially others.

If you’re unable to deactivate this setting, you may need to consider purchasing a different modem to utilize your inverter’s monitoring capabilities effectively. Alternatively, you can look to install a 2.4GHz WiFi Extender as a dedicated AP or Access Point to which your Inverter, and other 2.4GHz dependant appliances can connect to.

If you have a 5kW Export Limit on your 10kW solar system, this will be controlled in one of two ways. Firstly, your Inverter will simply “throttle” the production of your system so that you are not exporting more than 5kW of power per hour. Meaning, if at the time the household requires 2.7kW per hour to run base load appliance and say an air conditioner, your system will produce a maximum of 7.7kW per hour. 2.7kW to service the household needs and 5kW of excess power to export back to the grid.

Alternatively, your solar system will simply produce power as per normal for the conditions of the day, servicing the household requirements firstly, then exporting a maximum of 5kW per hour back to the grid, Any solar energy that your system has produced on top of that, (using the example above 2.3kW) will be wasted by the inverter or the export limiting device, typically as heat.

By using a high quality inverter with export limitation programming you may be able to install a larger solar system than you would otherwise be approved for whilst still complying with your network distributors export limits.

A larger system will produce more power throughout the entire day but will generally only reach an export limitation during the peak of the day. You will benefit from the full capacity of your solar generation whenever your households current demand + export limit is less than the current solar generation. Typically this will be during the mornings, late afternoon and whenever you have high usage throughout the day.

Batteries will be limited to the single phase they are connected to for both drawn down and blackout protection i.e using the stored power.

In most cases this system setup is still an ideal outcome, as the majority of three phase properties will still have the bulk of the household appliances and circuits on their primary phase to which your battery is connected. While other heavy use items such as pools, three phase air-con, irrigation or mechanical equipment will generally be on the secondary phases. These items often require more current to operate which would in turn, exceed the batteries output capacity and force it to shutdown and you would again have to drawn from the grid for electrically safety reasons.

This is why it’s current best practice to isolate the battery to the primary phase so the household genuinely has a reliable ‘emergency power supply’.
