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  Excellent long established family company with extensive experience in all things Solar. I researched a number of companies and All Green were by far the best value with the highest quality components. Highly recommended!

    • 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  Fantastic friendly service, very professional installers. Pricing was really good and they explained everything in simple terms that I could understand. I would have no hesitation recommending them. Even though they were from the central coast they were happy to come to Sydney and were always on time. It’s awesome dealing with companies like this. Thanks all green

      5 star review  Excellent experience with All Green getting our solar panels fitted. Joel and the boys arrived on time and had the job finished in about 4 hours. The solar panels have been producing heaps of power since installation and we have not used any electricity in that time.

    • 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  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  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  May I thank the installer Dave who came around today to troubleshoot and fix my network connectivity with the Enphase envoy. He went to great trouble to hook it up via ethernet so it’s much more reliable and I’m thrilled about that. This is the sort of excellent post-install service you want but don't always get. Recommend.

      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

      5 star review  Great advice and service and I don't regret selecting them. They are not a pushy solar marketing outfit. I have recommended them to friends who are looking for solar. They were very patient and helpful while I watched shading issues during different times of the day in the weeks before I made a decision. My observations just confirmed what they had proposed. I was very happy with the installation process. What they said I could expect to be generated on my site and position is on target with what is actually happening.

      5 star review  We engaged All Green to install solar panels and a Tesla Powerwall 2 at our house. They did a timely, efficient job, and we are very pleased. They went through the system with me, including demonstration of "grid down" performance. They provided clear answers to my questions. They also left the place clean and tidy. An excellent job all round.

    • 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  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.
