Output Efficiency

As your solar panels age the output they deliver will slowly decrease, known as panel degradation.

It’s not something to worry about as long as you shop reliable brands that have been around for a long time thus reflecting a good track record with their products. Most brands on the market guarantee 90% after 10 years and 80% after 25 years. Remember the warranty is only as good as the company backing it. One of the benefits of using Micro Inverters or optimisers is that each panel will perform it’s own individual best so as the system ages the benefit of these systems increases.

Panel Output

24054058 panel output allgreen 1 768x313 1 500x204 - Output EfficiencyIf you buy 10L of water at the supermarket regardless of the brand, packaging or price, if you take it home and pour it all into a bucket its still just 10L of water.

The output from a 10kW Solar system is going to be the same regardless of the price, size and shape of the panels. A higher output or more efficient panel means less panels and less roof space, along with a higher price but it won’t actually make more power than another 10KW system. Testing of panel performance shows most of the major brands on the tier one list are within 1% of each other while using Micro or optimised systems can increase efficiency by 8% and this increases with the age of the system as individual panel performance starts to vary.

The verdict is the inverter is the more important of the two components. It will determine performance, reliability, warranty, maintenance, compatibility, monitoring and future capability.

  • 5 star review  Great service end to end - bloke came out in person to discuss options (all others were phone or didn’t show), clear quotes, very professional and friendly team of installers on the day. Couldn’t recommend these guys more, 5*

    5 star review  Fantastic team to deal with. Within an hour of the install (which only took half a day) we were making more energy then we were using, and that was on a cloudy day! Highly recommend.

  • 5 star review  From the very start, Joe was competitive, and engaging with the quote.Joe provided a lot of background links to help in the education process, and help determine the right system for our house based on our budget. Then when it came to the install, Bryce and his team were here promptly. They were very engaging, and extremely efficient - done in 4hrs. Enjoying monitoring production and consumption, and looking forward to low energy bills and doing our little part for the environment. Thanks to All Green Environmental Solutions.

    5 star review  I had an issue with my Enphase system which was installed by another local company who went bankrupt, effectively voiding my labour warranty for good. All Green Environmental Solutions weren't obliged to assist me, being very busy with their own clients, but they did !. Their response was prompt and professional throughout. If you are looking to install solar, I am sure you will be safe in the long term and well looked after with this company. Thanks again .

    5 star review  I don't normally write reviews but decided to do it for All Green as I had a great experience and smooth transaction with them. Joe on the sales end was really great with understanding the needs and providing analysis for couple of different scenarios. He didn't try to push me to sell the biggest system and provided the optimum one that'd suite my need. It took a while to get it installed, but Wayne and the crew was great on the day. They had all the equipment and didn't even have to come inside the house. They did all the work from outside which was great as I was working from home that day. The job was neat and I didn't have to a tidy up after they've left. Emma and Kylie in the office were great to deal with as well. The system is working like a charm and automatically shut down safely when there was planned maintenance in the electricity network. Thanks guys, couldn't have been a smoother transaction. I'll be recommending you to everyone who's considering solar

  • 5 star review  A highly professional experience from start to finish. The sales team provided all the information we needed in an easy to understand format with very competitive pricing. Once we decided to go ahead with the purchase things moved along quickly and within a short time the installation crew arrived. The crew were very helpful and friendly, explaining all the steps and downtime was kept to a very minimum amount of time. No more than 15 minutes or so. The monitoring software was installed and explained in detail and the empty boxes, etc was cleaned away. A reassuring aspect of the monitoring software is that in the event of a problem All Green will contact me to let me know what will be done and when, not the other way around as is usually the case. Top marks on all aspects of the deal from start to finish. Well done. I would recommend All Green in an instant.

  • 5 star review  Competitive pricing. Installation crew on time, polite, efficient and answered all my questions. Really appreciated the call a half hour before arrival letting me know they were on their way. Recommended Enphase micro-inverter system is great. Monitoring software is fantastic. Could not have asked for a better experience.

    5 star review  All green environmental solutions installed a large solar system and Tesla battery at my elderly neighbours house (who I was assisting) on the 20th of August, 2020. The installation team came early in the morning, and after consulting with us about what they were going to do, they got to work. The whole process took less than a day, and the men were very efficient and courteous. At the end of the day, the system was tested and up and running, and they left the worksite tidy. Would highly recommend the company if you are thinking of putting in a system. Cheers, Phillip and Dennis. 😊😸

  • 5 star review  Very pleased with the solution that All Green Environmental came up with. It wasn't the easiest installation with a very steep roof but the installation team did very well and the system was up and running the same day. Very efficient, no mess and I now have 'free' power. Would definitely recommend them.

    5 star review  All Green were quick and efficient at installing my panels. I've just received my first power bill since the installation and I am very happy with the result. Recommend.

  • 5 star review  All Green Environmental Solutions this week installed a system for us in Northbridge NSW - 8Kw system with 26 Jinko panels and Enphase microinverters. It was the first company I contacted and after meeting with Gary Adair on site having already read reviews of the company, I decided not to bother with competitive quotes. And I wasn't disappointed. The 3 man team led by Bryce turned up as promised at 9am last Tuesday and by 4pm that day we were up and running. Company staff have been both efficient and courteous. Whilst the price I paid is definitely not the cheapest I could have obtained, the professionalism of the company and the confidence that engenders more than makes up for it. I would wholeheartedly recommend All Green Environmental Solutions to anyone considering a solar system.

    5 star review  I was referred to All Green Environmental Solutions by a friend and I am so glad I listened. The job entailed installing Enphase solar panel system and a Tesla Powerwall 2 at my house. This was done efficiently with the work being completed on the day of installation with no issues. They setup the system so that I can monitor it on my phone, answered all questions I had and were professional throughout. I highly recommend them
