Solar Repairs FAQs

How much does it cost to repair a solar panel?

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.

Can you refurbish solar panels?

Unfortunately, solar panels can’t be refurbished as the technology changes so rapidly – new solar panels are not compatible with the older panels.

How often should solar panels be serviced?

Solar panels should be checked at least once every 5 years as recommended by the panel manufacturers.

How do I know if my solar panels have stopped working?

Typically one of the following would indicate your solar panels are broken or have stopped working:

  • your electricity bill is much higher than normal
  • there is a fault light displayed
  • there are no lights displayed
  • there is no display
Why do solar panels break?

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.

Can solar inverters be repaired?

Solar inverters can sometimes be repaired, depending on the cause of the issue. Contact us so we can get some more information.

What does the fault code on my solar inverter mean?

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.

What happens when a solar inverter fails?

When a solar inverter fails, it could be a warranty issue or a minor technical fault.

What causes solar inverters to fail?

Solar inverters seldom break without external influence unless they are poor quality inverters. The most common causes of inverters failing are electrical storms.

Will I lose my warranty if I don't service my solar panels with the same company I previously purchased them from?

No, we’re able to carry out a full service and maintenance on your solar system without voiding your manufacturer’s warranty.

Residential Solar Systems FAQs

How much does a 6.6kW solar system produce?

Typically, over the course of the year, a 6.6kW solar system will produce around 30kW per day.

How do solar panels work at night?

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.

How do solar panels work?

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).

How many solar panels do I need for my house?

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.

How much do clouds affect solar panels?

Solar panels continue to generate power even during cloudy days, but they produce less power than on sunny days.

How many solar panels do I need for a 200 square meter home?

This depends upon the cost of your electricity bill – call us and one of our consultants can help further.

Can solar panels be removed and reinstalled?

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.

Which solar brands do you install?

We supply and install all the major solar brands we have confidence in from our many years of experience, including LG, Tesla, SMA and Solis.

What happens to solar panels after 25 years?

Solar panels will continue to work for longer than 25 years but the solar power efficiency declines as the years pass.

Who can remove and reinstall solar panels?

This is best left to a solar company that specialises in solar power installation and repairs such as Solar Water Wind.

Commercial Solar Systems FAQs

How much does a commercial solar system cost?

Typically, commercial solar panel installations have a 2-3 year return on investment based upon the quarterly electricity bill – contact us for more information.

How much power do commercial solar panels generate?

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.

What is the lifespan of a commercial solar panel?

A commercial solar system has a lifespan of 20 – 25 years.

Solar Micro Inverters FAQs

How does a micro inverter solar system work?

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.

Are solar micro inverters worth the extra money?

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.

How much does a solar micro inverter cost?

Micro inverter systems are generally 20-30% more expensive than a standard solar system

Are solar micro inverters better than standard solar panel inverters?

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.

Are solar inverters covered by insurance?

Solar inverters are covered under the homeowner’s building insurance policy.

Which type of inverter is best for solar panels?

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.

What is the difference between a string inverter and a micro inverter?

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”.

How long do solar inverters last?

Most solar inverters have 10-year warranties and are expected to last 20 years.
