Thanks for breaking this information down into simple language I can understand.
Love all these videos! Thanks Finn!
Very good video for home owners who want solar energy to their houses. Thanks.
Thank you for the wonderful presentation
Thanks for explaining the difference between kw and kwh!
the lesson is really easy to understand, thank you
Thanks, very complicated, so much to worry about
great video thank you
Great video, thank you.
Is there a solar calculator for the UK? Great video!
About time you got better thumbnails! Your CTR is now going to be so much better. Now hurry up and make better use of your green screen! 😂😊
How do you correctly size the solar vs battery capacity? I am getting a 4.3KW system installed with a 9.5Kwh battery and I don't know if I should consider more panels or doubling the storage to 19Kwh (can't afford to do both) I live in the UK and my predicted generation of the system is around 4000Kwh per year.
Just installed an AlphaESS 13.5Kw battery coupled with an 8.1 solar array. AGL reduced our feed in to 5 cents (plus a monthly charge of around $20) This resulted in us ‘giving’ tons on KWH’s away and still getting bills from AGL. Three months in with our battery and it seems to have been the right move. While it doesn’t have the intelligence’ of the Tesla, it has the blackout protection and the ability for me to look at the weather and the battery (through the app) and make a decision to charge from the grid during the shoulder period (19c / KWH) to attain 100% for the peak evening period.
I have the 10.3kw alpha.How you liking yours?
@@chefgav1 Loving it so far. 3 months in and there’s been a dramatic reduction in our AGL account. Last month it was $4.00. I might add - our grid usage for the month was 26 KWh and our feed in (back to AGL) was 760 KWh - but they still managed to find a way to charge $4.00. Definitely happy with the battery though.
@@GeneLake001 ACT government offer really good incentives with 10 year interest free loans and battery rebates with ACT accredited installers here. $8900 installed over 10 years gets me a 10.3 kw alpha with 6.6kw jimko Ntype panels. Bargin
Why they are charging you for that $20 per month?
@@MohsenHaji_Au It’s what they refer to as an ‘Admin Fee’.
I’m sure there’s a rational reason why they can only afford to pay me 5 cents / KWH and resell it at whatever exorbitant cost of up to 42 cents / KWH - but I’m yet to work that one out.
Learn and install your self. I got charged 16k for solar panels and inverter but when I checked the installed equipment price it was only 4500. They rip you off badly. Get an electrician friend to check everything before powering on. Happy saving
Great video
I recently invented and received a patent for a fire suppression device that protects homes from wildfires. It runs off WiFi I know I will need to consider power shutoffs. What do you recommend to keep my WiFi on so I can activate my suppression device?
I appreciate any help.
Greeting from Seattle. Recently saw a video on honeycomb solar panels. What are your thoughts, are these the future? If so how far out in time until they are sold to the public?
If brownout blackout is a reason or a thing in your area look at switch over speed.... don't go Fronius it's crazy slow at 90 seconds... also it's uses the grid for any increase till it actually works it out...
Hi... I love watching your videos. I have a very odd question. I am living in Italy and the cost per KWH are getting out of hand.
I was thinking of getting a solar system..... ok till now nothing special as of a question.
My father lives next door in an attached home and was thinking of sharing my solar system with my dads house with an ats switch without having 2 set ups.
Is this even possible or am I better off with 2 solar systems?
If I have opt for 2 systems is there some way we can share a huge battey instead of having 2 separate ones?

Stanford engineers develop solar panels that can generate electricity at night
Power generation at night is produced from radiative cooling of a photovoltaic cell

Nice video for an overview. Im german and it was interesting to see how grids are build in other countries. In germany we dont have time of use tarifs. We pay 24/7 the same amount. With an old contract its 30 Cent/ kWh. If your electricity provider raises it the price its more like 40-60 Cent / kWh or more
participateing in a VPP is currently also not possible
The other variance between Australia and Germany as far as I know, is how the grid exports work (called "Feed in tariffs").
In Australia, there are 3 main charges
1. The cost to import (which may be time of use or might be one standard rate)
2. The feed in tariff
3. The daily usage charge (a flat fee for being connected to grid which is usually under a $1)
The feed-in-tariff is usually less that the cost to import (but not always).
In my case at the moment, I pay 16 cents to pull from the grid per kWh, but get paid 21 cents for any excess that I export per kWh.
For my 10kW system in practice, I would generally always be exporting (earning 21c) and self-consuming (saving 16c).
It's rainy and late afternoon right now. There is zero sun in the sky, but I am still producing 0.3kW worth of solar and currently consuming 0.5kW of solar.
So, if this snapshot of usage was steady for one hour, I am self consuming 0.3kWh (save 4.8c) and importing 0.2kWh (spending 3c). All up, saving 1.8c per hour.
On a sunny day....
I would be producing 8.5kW of power.
For a steady hour, I would self consume 0.5kWh (save 8c) and export 8kWh (earning $1.68).
Generally my energy company would pay my exports direct to my bank account each month leaving me generally, always in profit year round.
@@inodesnet what electricity company are you with? Those numbers are extremely different to the price I pay 😭
@@xx24nuggetsxx48 I am with AGL and Ausgrid. These are very recent changes.
I was expecting a trend upwards for cost of electricity. But AGL have decided to reduce ost per kWh and transferred some of that into standing charges.
@@inodesnet yeah true I look at there plans and I’d be getting charged 0.35c per kWh energy prices just seem to continue to be going up 😑
Has the price of natural gas increasing since the invasion of Ukraine impacted the rate you pay, or is Germany fully subsidizing their energy? We have time of use tariffs in the United States and I always thought that was typical
If you're grid connected and have solar and a battery, and generating enough to pay your connection fee $1a day, easy at the old rate 12.4c and 10.2c but 8c probably free with a 6.6system, you need to give 12kw a day average per annum, my 6year old 5kw system won't manage that, mind you I started pre battery with 6c feedin and have had a powerwall2 since 1st week August 2017.
One of the under appreciated advantages of using a DC coupled battery is, that by delaying charging the battery until 11.00 am or noon, more power can be exported to the grid in the morning with the battery either being charged by power in excess of the 5 kW grid export limit, or charged after 11.00 am or noon when the amount of power produced often exceeds the 5 kW grid export limit. So dramatic is this that my 13.25 kW pv array with 10 kW inverter can produce 15 kW of power by sending 5 kW to the grid, 5 kW to the battery and 5 kW to my house and EV. In a DC coupled pv system the true limit of a system is therefore not determined so much by the inverter's limit but rather by how the inverter is configured and whether the array can produce more that 10 kW of power.
My DC battery is charged from the excess power from the array
Wow, Tesla powerwall2 have gone up in price, my powerwall2 was installed 1st week of August 2017 $10,805.38 fully installed including gateway.
Are pylontech home battery being imported to Australia yet?, there supposed to be really good, used with victron inverter.
Look at Red Earth.
3.55kw Ptlontech batteries.
Aussie made company
10 year wananty
Forget VPP
These guys are gunna have Personal Power Plant
Who can help me with incorporating my deep cycle lead acid latest battery bank to my domestic recent solar panel array...jon..
Surprised he didn't talk about max ampere usage like his Tesla that only has 30amps, even if you got usable 5kw from the inverter if you use something that uses over 30amps with low KW you'll shut off your battery
July 2025 is when mandatory export tariffs come into effect according to the Draft AER guidelines. Might be a good idea to get a battery to avoid export tariff when it comes in. Hopefully by then individual households will be energy independant and use ZERO energy from the grid.... Good Riddence Grid!
What county/ state is that in ?
@@kerrynball2734 I believe it will apply to all states and territories. Note, it's a draft so may change depending on stake holders. Please download and read it yourself.
@@whoguy4231 I was under the impression that at some point they would insist all systems have built in ability to stop export by the grid manager. But it would apply to already installed systems. Retrofit would be a nightmare.
@@kerrynball2734 AS/NZS 4777.2:2020 is for all new inverters/batteries to reduce or stop export to the grid. The mechanism the power providers use is by raising the grid voltage to various residential areas and in response, the solar inverters/batteries in that area will reduce output to 20% or even off. The AER guidelines is talking about grid exports being charged to the homes and how they would charge such as higher charges in the day and lower charges at night.
after watching few of your videos, I came to the conclusion thats it's too hard and costly to get dependable solar system upgrade. too many gangsters in the industry.
It’s not that bad.Plenty of great ones
Australia still has the cheapest installed residential solar in the world.Worth it 100%
I got a 6.6kw solar system with 10.3 kw battery fully installed $8900 10 year warranty and 10 years interest free and the Installers were great.CEC recommended retailers and installers. ACT government recommended installers and a Finn pick of installers. Win Win
I found the process was like buying a used car. Some ‘shady operators’ out there and kept clear of those. My experience was positive with the solar array people and later the battery people.
And utility are still the scum of the earth for charging that $25 fee for being “ connected” to their grid.
Booooh
