Biosolar in LiquidationIf you have been trying to contact Biosolar to claim a solar warranty you may have found they went into liquidation and closed their doors in September 2014. Another solar sales company goes bust, and a host of customers left trying work out if their warranty is still valid. The faults your solar system will have will either be with your panels, your installation, or your inverter. The labour content of your warranty will no longer be covered – but it’s not all bad!

*DISCLAIMER: MC Electrical is not affiliated with BioSolar or any other third party sales companies. However, we have been in the solar industry for over 12 years, we know who does good work and who doesn’t. Although we’re too busy to do any service or repair work ourselves, we can definitely point you in the right direction, so feel free to call the office on 07 3268 3836 and we’ll be happy to recommend someone for your area.

Panels fault

Your panel will probably be CSUN, Yingli or Sungrid. All three panels were considered quality.

CSun is a still tier 1 panel, but is a lower grade tier 1 from a look at their price, their MC4 connectors, and their JBoxes. In saying this, we have not had to replace a CSun panel to date.

Yingli has always been considered a quality panel, though recently they have gone through significant financial difficulties as a company. We had had a faulty Yingli panel recently. After a several emails with Yingli, we were able to prove the fault was indeed with the panel (inside the junction box). Yingli somewhat reluctantly honoured the warranty.

Sungrid. From what I can tell, The Australian company Sungrid is no longer. Philip Livingston was the founder, and has now started up Redback Technologies. In January 2013, Sungrid was acquired by Urban Group, where Phil was director. Urban group of companies included the now notorious CO2 Markets and Go Energy. These companies were wound up in April 2016. Here are the contact details below – let me know if you find something I couldn’t!

I have had two cases where Sungrid panels had  “spider legs” in the cell. If this is the case and your system is performing poorly, it will be worth replacing all panels. Fortunately, the REC scheme covers most of the cost of replacing panels. It still may cost you $1000 or more for the labour and bringing the system up to current standards so we can claim the REC’s.

Installer error

Bio-solar used subcontractors to do their installations, which often would mean installation issues. However Bio-solar were exceptionally good at quality control, sending inspectors around to every installation after it was complete. So, while your installation is probably not a disaster, mistakes do happen, and you may have workmanship fault. The most common workmanship fault we find is water ingress in DC isolators and hot connections in MC4 plugs. These issues are an easy and often inexpensive fix. Again, we can help you with that.

Inverter faults

BioSolar mostly used Aurora (now ABB) inverters, and they occasionally used Samil inverters. As these inverters both come standard with a 5-year warranty, and BioSolar was founded just over five years ago, your inverter is probably still in warranty.

ABB inverters were, it seemed, one of the best inverters on the market at the time. However, in the last 12 months we have seen our fair share of ABB faults, to the point that we have formed a good working relationship with the ABB warranty department.

Samil inverters, on the other hand, are more of an average inverter – especially the earlier models that BioSolar installed. Getting warranties through the Chinese company can be a little more tricky, and you may be waiting a while – but we’ve never failed to eventually get one replaced. Samil no longer pay for the labour to replace the inverter, so you may be up for 2 callout fees if required.

So who covers the warranty?

Although BioSolar is closed, your panels and inverter should still be covered under the manufacturer’s warranty by the manufacturer. However identifying the issue and workmanship errors are not.

MC Electrical is not affiliated with Biosolar in any way, and we have not taken over their warranty. However, for a charge, we can identify and repair a fault, or lodge a warranty with the manufacturer. You should be able to have your solar up and running for less than $300 providing the inverter manufacturer pays for the second call out.

If you’d like help you getting your solar up and running again, give us a call on 3268 3836.

Hi Kevin. Best to contact an installer in your area to get them to take a look. If you're in Brisbane, give us a call and we'll point you in the right direction.

    Kevin Slavin said :Guest Report one year ago

    Hi there, I came across your site trying to report an issue with my Solar system installed by Bio Solar back in 2012. I have noticed over time now that the system doesnt seem to be as efficient even after a clean and now i have noticed that intermittently the display is going into this "checking mode" for about a minute which it counts down and when reaches 0 goes back to normal and starts making power. I am not sure how many times it does this a day but I think a lot. I have a picture but cannot attach here. Wondering if you could give me some advice on how to proceed with getting this looked at/fixed. thanks Kev

    Hi Terry. That's a common Aurora inverter fault. Time to buy a new inverter I'm afraid.

      Terry ROWEN said :Guest Report 2 years ago

      I am getting an error message on my inverter (message 031). It is an aurora inverter installed April 2014 which is probably outside the warranty period. However i am more concerned by the message and would like to talk to an expert and get his thoughts

      Hi Maria, you'll need to get a solar trained electrician to go out and test the inverter and panels.

        Hi Kym. Looking at how much solar you are exporting to the grid is not a helpful way of assessing how well your system is working. You need to read your inverter production over a period of time and see if the average is similar to the predicted average. You should be able to get in contact with a local electrician how will charge $200 - $300 to check it out - but get them also to show you what to expect from your system.

          Kym Harding said :Guest Report 3 years ago

          I got my solar through biosolar and they have closed down I don't think my solar is working because my bills are still very high and I only got $9 solar export back this month not sure what to do could you please back to me thank you

          Hi D Chandra, Probably could be repaired but personally, I wouldn't. It wouldn't be worth the cost.

              Hi Lucas, Sorry to hear that. possibly to do with the panels. We're not doing warranty work at the moment due to a backlog in installation work. Best to call "solar service guys." Mark

                Lucas Naughton said :Guest Report 5 years ago

                Getting an RSO error think it's to do with the isolators ? 0.40 is what it says on the inverter yet manual says to contact someone to fix it as it is not something simply repaired. Could you call me sometime in the future please. Biosolar has sold me a lemon as i've already had you lads replace my inverter.

                  Hi Kerryn, I think I spoke with you this week about your Job. Believe it or not, "Spider cracks" or "snail trails" are generally considered cosmetic by most panel manufacturers. They say it does not affect performance. They often occur because they were handled poorly in transport, or were stood on during installation or maintenance. To be honest, if you can't get a warranty, I wouldn't be to concerned about it and just keep an eye on your average daily production. Mark

                    Di said :Guest Report 6 years ago

                    Hi we had solar from Bio Solar fitted in early 2014. We have an Aurora Inverter and we are getting the message missing grid. Would you be able to recommend someone in Sydney who could come out to help us please. We are in the hills district. Cheers Di

                    Hi Bio Solar installed 24 panels in Sept 2014. Just had panels taken down for a roof respray and at least 50% have spider cracks that have been identified by the solar people removing them. They suggested I get in touch with warranty manufacturer as they are not performing property and dangerous. Who can I speak to and how do I find out which of the above manufacturers they are from. I am in NSW

                    Hi Sam, if it has already been diagnosed, then call ABB - or better still, get the electrician to lodge a warranty.

                      Sampath Padmawansa said :Guest Report 6 years ago

                      Hello, My ABB inverter, installed on 23/07/2013 has packed up. (This was identified by a professional electrician). How do I get this replaced as it is still under warranty ? Sam

                      Hi Graeme, If you find you have a loss in production, it would be worth looking at replacing them. However, you might find the loss in production is minimal. As a rough guide, in Brisbane, this system on an unshaded roof you should be producing 22-24kwh of power on average throughout the year. (clear Summer days should probably be well over 30kWh depending on your panel layout) Sungrid are no longer around, so you would have to replace all of your panels. With the way the rebate works, it may just be better to replace your system! Mark

                        Bio Solar installed a 6KW system for me in January 2014. I have recently discovered that 16 of the 24 Sungrid SG250P6HP panels have micro-cracking, which looks like the "spider cracking" in your photo above. What can I do about this problem ?

                          Hi Dallas, The lights going off at night is normal. The GFCI failure means the inverter has failed. If you can reset it that's good, but it probably won't last. I'm afraid the warranty process with JFY will probably take a few months, and you will have to pay for the labor. You will end up with a refurbished SunTwins (which is a poor quality inverter). You may want to consider replacing the inverter for a good one at a cost of $1500 to $2200 depending on what you replace it with. Mark

                            Dallas Aitken said :Guest Report 6 years ago

                            I left a message yesterday. The inverter is a Suntwin 5000TL. I can reset the alarm in the morning (GFCI failure). The inverter works fine all day. As it gets dark all lights and displays go out (not sure if this is normal) and in the morning the alarm light is back on. Is this an inverter fault ?

                              Dallas Aitken said :Guest Report 6 years ago

                              Our 5 Kw system was put in 2 years ago by biosolar ID 7337. Inverter is coming up with a GFCI fault (ground fault). It will reset and run for a while but the next day it has the same fault. Not sure if it faults quicker with full sun, been overcast the last few days. Any suggestions?

                                Good Luck with a Samil warranty! They are still in business in Australia but are impossible to get in contact with I'm afraid. If you call into the office we can advise you on options.

                                  Hi Michael, We have not had any luck contacting Samil. They are still in business, an industry friend visited the office/warehouse recently. It's probably best if you just replace your inverter than wait 6 months for a warranty that may or may not come. If you are in South East Qld, call us and we can assist. 32683836
