Just upgraded my original ( all I could afford at the time) 6.6 kW system to a 13.2 kW by adding s 6.6 kW system on the South facing side of my roof. So far for the first full month (June) it has added 218 extra kW which is not too shabby compared to the 418kW of the 2021 vintage 6.6 kW dystem for a total of636kW for the month. Looking forward to the best output months to see how it puts out then
I am glad that even nearly 10% is not enough. In thailand, less than 1 percent we are still worried that's too much as the policy tries its be to prevent people from jumping into solar.
…great info & it helped get the wifey on board for our new 13kw system (go big or go home!)…can we find a bit more info on the Volvo mechanic’s Solar investment on solar quotes website? …we’ve got a lot of roof space …if I can pitch a ROI of 4 year for a big installation, the wifey might be keen to jump on board :-) …the most panels you can have on 3-phase is 40kw?… does this guy have 6-phases, to do 71kw of panels ? Cheers
Just take as many panels as you can, most of the time they will not hit that 6.6 limit anyway. And if it turns out it does : 1 : it is a luxury problem, focus on the extra energy during the hours it does not hit 6.6 2 : Consider placing panels in different direction to get more solar during hours you now are not getting much 3 : if it is financially interesting, buy a battery for time shifting (saving solar electricity for a later moment when otherwise you would have to pull solar from the grid)
On a good sunny day, I get my output clipped at 5.06 kW for a few hours. The real advantage of more panels is faster rise in output and more output on sub optimal days and also allows for no dropoff in performance due to a bit of panel degradation over its life.
In my area in Sydney with Endeavour, AGL is placing a 10kw panel limit for 12c FIT. My house can fit about 10.5 kw, I’m going to install less panels to stay under 10kw.
If you had EV cars charging their batteries at high solar times then the grid could handle it, right? Is the problem that the Sub stations can only handle power flowing in one direction i.e grid to consumer?
Yes - WA's 5 kW rule is really stupid. So bigger is not always better out West. But with the really low FiT, you can come out on top with a bigger system - if you have a lot of self consumption - using gear like the Catch Power. Our calculator will soon be updated to let you do the sums on this.
Hey Fin this is a quote I just received I wanted the max panels here in Perth I could instsll on my roof.Is the installer correct in saying " Please remember that the inverter is 5kW so the most you can ever use or charge your battery is 5kw" doesn't sound right to me?? Option 3 is the 5kW Huawei inverter, Huawei Smart meter and 8.88kW, 24 x 370W Jinko N-Type (20 year warranty) modules and the 10kWh Luna battery.Please remember that the inverter is 5kW so the most you can ever use or charge your battery is 5kW. The extra panels come into use during the winter months in still allowing the system to generate that 5kW. You will never see generation above the inverter size.
The battery is 10 Kw hours think of it as a 10,000 l tank being filled at 500 l per hour to reach full capacity. You then drain the tank as you need overnight.
Before sending solar power North send it East West this would allow a system on the East cost to start providing Perth power 3 hours before and Sydney 3 hours later. Europe and Asia your talking almost full solar coverage so I guess we might use that cable one day. Current Singapore cost Aus$ 0.22/Kwh
So the Inverters haven't gone down wow I thought that was the part most likely to go down Solar makes more sense to a Business as they use the power during the day and export less ad on can get some cashflow on the Off Days
I would love to know what are the export policies for a Grid-Tied Solar System in Australia. I own a firm that does these Installations, in India. Its interesting that you can get payouts from the utility.
Per phase, the inverter limit is 10 kW in the Ausgrid area in Sydney :) Note that you can go 33% larger than your inverter capacity with panels. So you could have 10 kW inverter capacity and 13.3 kW of panels on a single phase in Sydney. Much larger if 3 phase!
Thanks Finn Just a follow up question, to your answer to the question about what happens when your system can't consume/export the full productive capacity of the PV array. You sort of missed answering the second part of the question, about potential for damage. While the inverter manages the throttling of output quite nicely, there is still solar radiation striking the panels. Presumably instead of the component of radiation being converted to electrical energy it now results in the panels getting hotter instead. I expect they are designed to cope however stuff which runs hotter more often, in general, doesn't last as long. Is this extra heat of any concern for the longevity or rate of degradation of the panels? Alex
@@SolarQuotes No surplus electrical energy, however the radiation energy striking the panels doesn't just disappear. If it's not converted to electrical energy the radiation energy striking the panels has to go somewhere, so presumably it makes the panels hotter than they would have been had it been converted to electrical energy. I was wondering if this extra heat may result in faster panel/panel component degradation?
@@alexsimmons1803 You appear confused how solar panels work. They turn light into energy not heat into energy. Panels will get hotter as sun falls on them whether power is drawn from them or not, if anything they'll get hotter as power is drawn from them due to the current generating some heat (nearly insignificant amounts thought).
@@billmastrippolito7132 I'm not confused, I'm asking a question. If light energy is hitting a panel in normal operation, some of the light energy (visible and a bit of UV) is being converted to electrical energy. Yes some of the resulting electrical current will generate a little heat. However if the MPPT is preventing the conversion of that light energy into electrical energy, then the light energy must go somewhere (basic thermodynamics). I figure it must be converted into heat but please enlighten me on what happens to that excess light energy?
@@billmastrippolito7132 Here's another way to think of my question: Imagine two identical panels next to each other, each facing the full sun. One is connected to a solar inverter and supplying electrical energy. The other is not connected and hence no electrical energy is being generated. Will there be a temperature difference between the panels?
A bit off topic but.... why do people always say "nice sunny days"? I prefer nice cloudy days. I also prefer winter over summer here in Australia because summer sucks. Not so good for solar though.
Upgrade the grid to handle more solar. will that really be done now that the government has privatised it ? We were not allowed to build a system with more than 5kw export. So how can I add more and limit use more, I wasnt to isolate the shed, add a battery and run the pool pump from that, can I do that ? Its only 1kw or motor, 1.5 for startup so a 2kw inverter and will do and old recycled panels but not grid tied, right ? who do you get to organise that ?
The high legacy Feed In Tariff means it has certainly paid for itself. Which was the idea behind initial high feed in tariffs. People bought expensive solar, kicking off the industry. Now SA has the most solar per capita in the world. A government scheme that worked!
Obviously lots of clean cheaply produced energy is a good thing. However, AGL (for example) will currently pay 15 cents per kwhr provided you have less than 10kws of solar panels, if you have more the fit drops to 6 cents. Putting up a 10kw system makes economic sense but not say a 12 kw system.
That's a good point. Silly rules like that can skew things - but don't forget that there are other retailers out there that may be happy to pay you for bigger systems www.solarquotes.com.au/energy/
Big is not better always.... I have 5kwh limit.... 6kw inverter and 9kw panels. 11kwh batteries. The inverter is is capped at 5.5kw for most of the day. As base load is 500w avg... So if went 10kw it would be doing nothing bar bad winter days.
Stop playing kissy face with utilities, store all your own power and be selfish with it. Here in California they charge you up to .44 cents per kWh yet will only buyback from net metering at a rate of .02 cents per kWh. Tesla made over 1.7 million cars thus far and there are approximately 19 module each car, each having 5.2kWh of storage capability.
Supply chain logistics allow that in the USA. Australia is limited by small population and size. Import laws on trademarks and electrical waste complicate mater's. Some great projects using waste Tesla battery's in the US. I just checked there are zero wrecked Tesla's for sale this week in Australia, RHD autopilot works better maybe?
I am sorry that I am critical. The 17 year-old panel installation- What a useless segment! All it said was that it was still working. How useless is that? A bit more information on how well it was working would have been better - what is the yield now compared to when it was installed, would have been much more informative. I am also sorry I find the "entertainment" frivolous and does not add any value to the video and is a turn-off for me. Otherwise the web page is full of useful information.
@@bluesolarmx serious question was that a typo? "China Canadia Solar PV Module Monocrystalline Solar Products, Find details about China Solar Products, 500watt Solar Panel from Canadia Solar PV Module " They are real genuine Canadian Solar panels you are using?
