Find out how much Energy Australia made from us yesterday.<!--more--><\/p>\n<p>We were meant to spend yesterday at another family member&#8217;s house for a get-together with the clan, but on Xmas Eve my better half received a phone call from her brother:<\/p>\n<blockquote><p>\u00a0&#8220;Hey sis, our air conditioner is kaput and the parts won&#8217;t be available until the New Year. Can we hold Xmas lunch over at your place?&#8221;<\/p><\/blockquote>\n<p>(or words to that effect).<\/p>\n<p>And thus began a bit of schedule rejiggering to hold the <span style=\"text-decoration: line-through;\">blasted<\/span> blessed event at our digs. My other half is very resourceful and flexible, so it hardly fazed her. As for me, it seemed the future of life on this planet as we know it was suddenly threatened. But I was curious to see how having all these heat-producing bodies in our space would affect our energy consumption; particularly given some would be entering and exiting the house frequently.<\/p>\n<h2>The Scenario<\/h2>\n<ul>\n<li>21 humans (including us) + a Jack Russell<\/li>\n<li>A 10-year-old, not-particularly-efficient ducted reverse-cycle <a href=\"https:\/\/www.solarquotes.com.au\/air-conditioning\/\">air conditioner<\/a> set to 25\u00b0C in 3 zones for nearly 9 hours. This was very luxurious for us, as it&#8217;s usually set at 2 zones and 26\u00b0C for far shorter periods on hot days.<\/li>\n<li>Brick veneer home, double glazed windows, plantation shutters and roof insulation.<\/li>\n<li>Some microwave, convection oven and air fryer cookery, along with sundry electrical appliances.<\/li>\n<li>10 kW of <a href=\"https:\/\/www.solarquotes.com.au\/panels\/trina-review.html\"> Trina solar panels<\/a>, an 8.2kW <a href=\"https:\/\/www.solarquotes.com.au\/inverters\/fronius-review.html\"> Fronius inverter<\/a> and a Fronius Smart Meter.<\/li>\n<li>Solar system <a href=\"https:\/\/www.solarquotes.com.au\/blog\/solar-export-limiting\/\"> export limited<\/a> to 5kW.<\/li>\n<li>Outside temperature reached 34\u00b0C, 30\u00b0C before 11 am.<\/li>\n<li>Fairly clear conditions for most of the day; a bit of scattered cloud in the morning if I remember correctly.<\/li>\n<\/ul>\n<h2>Here&#8217;s What Happened<\/h2>\n<p>So, here&#8217;s how things went; using a slightly butchered graph generated by SolarAnalytics based on data from the Fronius Smart Meter.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-69195\" src=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2022\/12\/solar-production-consumption.png\" alt=\"Solar energy production and electricity consumption\" width=\"900\" height=\"591\" srcset=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2022\/12\/solar-production-consumption.png 900w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2022\/12\/solar-production-consumption-300x197.png 300w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2022\/12\/solar-production-consumption-768x504.png 768w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/p>\n<p>Breaking it down a bit:<\/p>\n<ul>\n<li>There was some simultaneous convection oven, microwave and air-fryer usage around 9.50 am.<\/li>\n<li>Air-conditioner went on at 11.30 am. You can see it ramping up and down for the next hour.<\/li>\n<li>Folks started piling in at 12.30 pm, and external doors were opening (very regularly) and closing (with some reminders) from that point on.<\/li>\n<li>The <a href=\"https:\/\/www.solarquotes.com.au\/blog\/inverter-clipping-throttling-mb2718\/\">inverter was clipping output<\/a> solidly from 12.40 pm to 2.40 pm<\/li>\n<li>For whatever reason, the graph points cut out after 8.55 pm. Perhaps someone fell asleep at Fronius and it will update this morning. But between that time and midnight, there&#8217;s probably only around half a kilowatt-hour of usage.<\/li>\n<\/ul>\n<p>Being the life of the party that I am, I spent a lot of time watching system performance during the day. I also took a temperature reading of the panels at around 2 pm (excuse the image quality).<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-69196\" src=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2022\/12\/panel-temperature.jpg\" alt=\"Solar panel temperature\" width=\"900\" height=\"551\" srcset=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2022\/12\/panel-temperature.jpg 900w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2022\/12\/panel-temperature-300x184.jpg 300w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2022\/12\/panel-temperature-768x470.jpg 768w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/p>\n<p>They were getting pretty warm as the sun beat down upon them. A couple of minutes before this photo was taken, the reading was 50.6\u00b0C.<\/p>\n<p>The wattage rating of a <a href=\"https:\/\/www.solarquotes.com.au\/panels\/\"> solar panel<\/a> is based on Standard Test Conditions (STC); one of which is 25\u00b0C. That&#8217;s module temperature, not ambient. Above 25\u00b0C and panels start to lose efficiency. That&#8217;s where an <a href=\"https:\/\/www.solarquotes.com.au\/blog\/oversizing-solar-arrays\/\"> &#8220;oversized&#8221; system<\/a> such as ours can be of some benefit.<\/p>\n<p>Solar power covered everything from 6.55 am &#8211; aside from that reasonably brief consumption spike in the morning &#8211; until 5.15 pm. At that point I approached those who remained (18 of them!), pointed to the door and firmly declared:<\/p>\n<blockquote><p>&#8220;EVERYONE MUST LEAVE. NOW.&#8221;<\/p><\/blockquote>\n<p>Wasn&#8217;t this just meant to be lunch??? Anyway, they thought I was joking and totally ignored me. I didn&#8217;t chuck a hissy fit though as revenge is a dish best served cold. And speaking of cold, lunch extended into cold cuts for dinner for everyone. So much food!<\/p>\n<p>The last of the visitors left at 8.17 pm and the air conditioner was switched off as the door closed for the last time of the day.<\/p>\n<h2>How Much Electricity Cost Us For Xmas<\/h2>\n<p>The total electricity cost for the day was an estimated $1.12, including Energy Australia&#8217;s daily usage charge. The solar panels saved us an estimated $18.55 yesterday, which includes exports + consumption. I&#8217;m pretty happy with that; although exports appeared to a bit lower during part of the morning than they should have been under the conditions &#8211; so I&#8217;ll be keeping a closer eye on that today.<\/p>\n<p>Just on the consumption data &#8211; most <a href=\"https:\/\/www.solarquotes.com.au\/inverters\/\"> solar inverters<\/a> will show you energy production, but that&#8217;s only half the story. The Fronius Smart Meter enables us to also monitor electricity use in pretty much real-time via Fronius Solar.web, while Solar Analytics makes it all easier to see and to get a better read on the financial side of things.<\/p>\n<p><a href=\"https:\/\/www.solarquotes.com.au\/good-solar-guide\/monitoring-systems\/\">Consumption monitoring<\/a>, aka advanced solar monitoring, is an optional extra with a solar power system; but one well worth having to get the full picture of what your system and home is doing.<\/p>\n<h2>A Very Solar Christmas In South Australia<\/h2>\n<p>SA&#8217;s solar energy Santa brought big savings to hundreds of thousands of the state&#8217;s solar households on the day, while helping to rein in wholesale electricity prices for everyone. In fact, spot prices on the wholesale market in SA were in negative territory from around 7 am to 3 pm. This is nothing new, sustained negative pricing events have been going on for some time here (and elsewhere).<\/p>\n<p>According to <a href=\"https:\/\/opennem.org.au\/energy\/sa1\/?range=7d&amp;interval=30m\">OpenNEM<\/a>, rooftop solar systems across the state contributed more than 70% of SA&#8217;s electricity demand between 10.30 am and 3 pm; peaking at 78.4% at 1 pm. There were also a couple of days in the lead-up when that reached over 80% &#8211; the best was 83.9% at 1 pm on Christmas Eve.<\/p>\n<p>If you don&#8217;t have panels on your rooftop yet, make it one of your New Year&#8217;s resolutions to join millions of other Australians and <a href=\"https:\/\/www.solarquotes.com.au\/solar101.html\"> get solar installed<\/a> early in 2023. The longer you put it off, the longer you&#8217;re locking yourself into electricity bills much higher than they would otherwise be.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Some Christmas cooking, 19 visitors, an aging ducted reverse-cycle air-conditioner, a hot day and a rooftop solar power system.
