Here are some of the common questions we are most often asked about our solar services, including useful information on repairs to inverters and solar panels, and questions about residential and commercial solar systems.
If you have any questions about our solar services or products that are not covered here, or if you would like a quote, please get in touch by calling us on 02 4315 2391.
Depending on the fault, a solar panel repair may range from a few hundred dollars to a few thousand dollars, although faults are often caused by the failure of a simple component that can be repaired quite inexpensively.
Unfortunately, solar panels can’t be refurbished as the technology changes so rapidly – new solar panels are not compatible with the older panels.
Solar panels should be checked at least once every 5 years as recommended by the panel manufacturers.
Typically one of the following would indicate your solar panels are broken or have stopped working:
Solar panels seldom break without external influence unless they are poor quality panels. The most common causes of solar panels getting broken include electrical and hail storms or something physically falling onto them.
Solar inverters can sometimes be repaired, depending on the cause of the issue. Contact us so we can get some more information.
Various solar inverters have different codes but if there is a fault code it indicates something is not working with the inverter or there is a problem – contact us with the details and we can help.
When a solar inverter fails, it could be a warranty issue or a minor technical fault.
Solar inverters seldom break without external influence unless they are poor quality inverters. The most common causes of inverters failing are electrical storms.
No, we’re able to carry out a full service and maintenance on your solar system without voiding your manufacturer’s warranty.
Typically, over the course of the year, a 6.6kW solar system will produce around 30kW per day.
Solar panels do not generate electricity at night. The best option is to install a larger solar system than is required, and the surplus electricity is then fed into the grid to offset the electricity drawn from the grid at night time.
Solar panels convert energy from the sun into DC power (the same current you get from a battery) and the solar inverter then converts DC power to AC power (the same one gets from an electrical socket on your wall).
The number of solar panels is determined by two things – the size of your roof available for panels and the amount of electricity you consume. Determining how many you need is best determined by one of our consultants – please give us a call.
Solar panels continue to generate power even during cloudy days, but they produce less power than on sunny days.
This depends upon the cost of your electricity bill – call us and one of our consultants can help further.
Yes, although sometimes the cabling and rail they are attached to no longer comply with current standards and will need to be replaced when the solar panels are re-installed.
We supply and install all the major solar brands we have confidence in from our many years of experience, including Tesla, SMA and Solis.
Solar panels will continue to work for longer than 25 years but the solar power efficiency declines as the years pass.
This is best left to a solar company that specialises in solar power installation and repairs such as Solar Water Wind.
Typically, commercial solar panel installations have a 2-3 year return on investment based upon the quarterly electricity bill – contact us for more information.
Commercial solar installations have a faster payback period than residential solar systems as most of the electricity is used while the solar system is generating power.
A commercial solar system has a lifespan of 20 – 25 years.
Micro inverters operate so that each panel has its own single inverter which converts DC to AC power which can be used in your home.
Micro Inverters are used for overcoming very specific challenges and deliver value for money when used for these challenges. Contact us to discuss whether a solar micro inverter system is right for you.
Micro inverter systems are generally 20-30% more expensive than a standard solar system
Micro inverters are better when you have extensive shading or a multi-faceted roof. For other situations, a standard solar system may be better suited.
Solar inverters are covered under the homeowner’s building insurance policy.
Fronius and SMA inverters are considered the best available, although most reputable solar inverters carry similar warranties these days. Just be careful of the cheap solar systems with their cheap inverters which do not last.
Micro inverters operate so that each solar panel has its own single inverter which converts DC to AC power while string inverters generate power from the panels that are all connected together in a “string”.
Most solar inverters have 10-year warranties and are expected to last 20 years.
