Solar Power and Battery Storage

Roof top solar power installations are becoming a truly viable option for domestic households as prices tumble. Millions of homes across the UK, Europe, and around the world have already had systems installed providing them with clean and free electrical power from the great nuclear fusion reactor in the sky.

Here’s a step by step guide to how to get started and a bit of detail about the system I chose for my own home.

    Great video and well presented, reading the comments of minor corrections by others is frustrating People eh? Nowt as strange as folk. I also have adopted solar and battery storage and point to note that I did not realise at time of install is the stated battery capacity, the 4.8kw system is not a true storage capacity as the charge controller will not allow the battery to charge over 90% and discharge below 10% leaving only 80% of the advertised capacity it’s called Depth of Discharge (DOD) and protects the battery from over and under charging. I find now that my usage is matched and complemented by the battery system of 9.6kw giving 7.68kw of true storage. On fair days the battery is satisfied between 1130-1400hrs and will provide power throughout the evening for 3 adults. So for approx 3-6hrs per day I have surplus energy and have calculated that the greatest return of investment will be to replace the fossil fuel car with electric if I can afford one but not at the moment so the next user of energy is hot water and planning to fit a storage (15kw) tank to heat domestic hot water and offset my gas bill by utilising my excess PV. If any of you reading this and have an immersion heater system even if it is primarily heated by a gas boiler closed circuit then consider fitting an Immersun controller or any similar device as soon as you can as it diverts any excess PV up to 3 kwh to your immersion element, for me this should satisfy my families need for hot water for approx 8 months of the year.

    Thank you great video for someone like me that knows nothing about solar systems. I do have a question though, we installed our solar system last year and started it in June and I am wondering if we are able to instal a storage battery system to capture some if not all the excess solar energy we produce rather than sell it to El Paso Electric Co. Is this something allowable by the companies running the grid? Did you run into any issues about storage? Thank you kindly😀

  3. Jon Beale on April 13, 2021 at 12:02 am

    Thanks for a nice video. Have you calculated what the battery bank payback would be on its own? I have solar panels and the payback is about 7 years. I feel that ‘subsidising’ the batteries from the solar PV RHI payments isn’t showing the true battery bank viability (or not).

  4. pasoundman on April 13, 2021 at 12:02 am

    So, basically you’re relying on the grid for your winter (and much of your spring and autumn) energy needs. What powers your space heating ? I’m assuming it’s gas. 3kW is tiny compared to a typical central heating boiler’s output. Your batteries are most likely undersized btw.

    VAT on renewables going up to 20% from October this year☹️, but coal still at 5%!!

    Really interesting and very easy to understand.

  9. lolEpicgamers on April 13, 2021 at 12:11 am

    the main thing is cleaning it.. if its roof an auto cleaning panel would be an option even if it takes off some of the money.

    take a look at @t

  11. Vinylnuts on April 13, 2021 at 12:14 am

    Could you please do an update video on your solar Power and Battery Storage, I’m looking at getting it installed.

  12. Joss Ackland's Spunky Backpack on April 13, 2021 at 12:17 am

    Hi, I’m thinking of building a small 1kw system that would feed directly into the house, what equipment would I need to get hold of?

  13. 4QWzbaxSzUAq9 on April 13, 2021 at 12:19 am

    dude great info but your so white you disappear into the background also i personally like when the presenter is outside thanks truly great content no offense intended in fact my house keepers helper commented in spanish which she then translated to me ay Dios mío, esas son las piernas más blancas que he visto I said it gets even whiter if she wanted to see more …they all burst out laughing great content even if a bit depressing i have subscribed much success!

    I did 3.5KW solar installation on my home in 2012-2014. I started with 8 -100 watt panels. Added 8 – 180w panels, then added 4 -265w panels. I got all Monocrytastaline type. I have them running thru 24 volt grid tie micro-inverters. I have approx 25 percent allocated for charging 2 banks of 12 golf cart 220ah batteries. Batteries wired to 24 volts also and are used only for backup power. I do use them occasionally to run the refrigerator and garage door opener. I have had 2 extended power (3 to 5 days) failures over the past 4 or 5 years and the batteries kept m appliances running as needed.
    The grid tied solar has greatly reduced my electric bill and before solar i converted many lights to led to save cost. Im ready to replace by Lead acid battery setups with a Tesla Cybertruck as a battery backup source. With home solar and a EV battery that can be used as power source should be no issues of being without some power at any given time. Highly recommend solar. I did my system myself learning along the way. My very first panels were homemade and work quite well but only produce 65w max and are over built for RV use with 1/4 inch tempered glass and a 1-1/2" alum angle frame. I soldered all the solar cells together myself with the proper tools. I then poured a clear 2 part mixture over the cells to encase them in a protective layer impervious to the elements. I built those back in 2011. It so nice to see the prices coming down on solar finally. I calculated a 7 year payback for my system. In Michigan I only get 4 solid hours of direct sun daily due to some large trees blocking the morning sun to the east.

  16. Daniel Lantos on April 13, 2021 at 12:27 am

    Too expensive for the weather in England and how much sun you have here. Yes going off the grid in Africa where you have tons of sun is worth it.No, we won’t use electric cars, England will.

  17. Purplefox99 on April 13, 2021 at 12:27 am

    Great video, it answered a couple of questions I had about the economics. It’s August 2019 and I have a quote of £9.5k including VAT for a 3.5kw panel systems with 6.3kw battery storage. This’ll be in before the VAT hike on renewables to 20% in October. I’ve got my eye on a Smart Export Guarantee tariff as well, with your formulae I’m looking at an RoI of 16 years. I’m having Sunpower 21.5% efficient 350w panels with 25 year warranty and Solax battery with 10 year warranty, I’m also installing a MyEnergi Eddi, Harvi and Hub so should be able to make further savings by heating my hot water with solar power instead of gas. 🤞

  18. Robert Evans on April 13, 2021 at 12:28 am

    Southern hemisphere houses need the panels on the NORTH facing roof.

  19. romper stomper on April 13, 2021 at 12:28 am

    U do understand that the government are stopping paying people for there energy . They stop at the end of March 2020.

  20. Keeping It Real on April 13, 2021 at 12:28 am

    I think the post install is still 5% vat theres a reason for it but cant remember.
    I am having a powervault 3 added and that’s showing 5%.
    Btw I got a 4kw solar In roof installed for £5985 inc vat in April.

    I have a 30kw Leaf and that has reduced our commute fuel cost from £250 a month to around £40 .
    By changing to octopus agile and a Ohme cable, I expect to nearly halve the electricity cost .

  21. Robt The Good on April 13, 2021 at 12:31 am

    Can you update your figures to the present?

  22. vmgaspar on April 13, 2021 at 12:31 am

    One of the best solar energy presentations I’ve seen up to now. Thank you very much! I hope to have one system installed soon, but unfortunately I don’t think we have great professionals in the north of Spain yet, and the market is changing so fast right now!

  23. stefflmrk on April 13, 2021 at 12:31 am

    LOVE IT and don’t we all wish those lying global players (incl. Governments and others making BIG $£¥€ on fossil energy ) on what renewable energy will mean to us all in the future would get there big payback for NOT saying what the plane truth is!! Love this Video 👍🏻👍🏻👍🏻 Well illustrated, so the last ones would understand to re-think in many ways!

  24. Peter Staples on April 13, 2021 at 12:32 am

    The cost of a solar panel an unreliable panel s is falling but not hi-quality solar panels, they are rising in price. I have been using solar for over thirty years so may a bit longer than you. and is the most unreliable power that can be used as a substitute for baseload power and the most dangerous substitute power that I know of.
    You never answer the hard questions? There is a reason Heh? SO PLEASE HAVE A THINK!

  25. Just Me on April 13, 2021 at 12:32 am

    very nicely said !

  26. Robert Clark on April 13, 2021 at 12:33 am

    Brilliant thanks for sharing

  27. Paul F on April 13, 2021 at 12:34 am

    Unfortunately, the ROI on solar in the UK is crazy long. I was very excited initially about installing a solar, however, looking at installation prices it is just not worth it. It worth only if you DIY it, which is not possible for the house unless you’re certified etc. And if someone says it is to reduce his carbon footprint – there are more effective and cheaper ways, which will actually save you money like a used electric car and use green energy supplier…

  28. Ron Masters on April 13, 2021 at 12:36 am

    I connect to the grid, with equal rates in both directions. So I don’t need storage. I provide peak-shaving to the grid, it powers me at night. 😍

  29. Troll Face on April 13, 2021 at 12:38 am

    just have a stink.

  30. CoC HorrorShow on April 13, 2021 at 12:40 am

    PLEASE have a look at recent research done on zinc-bromine batteries (patent expired). Opposed to flow batteries, this battery is static (High-Performance Aqueous Zinc-Bromine Static Battery) and has a very low LCOES:

    This could be something for a DIY off gridder.

  31. MondoTV on April 13, 2021 at 12:43 am

    If I told you that adding a battery was actually increasing your carbon footprint in a grid-tied system would you believe me? (and that’s even ignoring the carbon footprint in manufacturing the battery). Check out this article frim SolarQuotes which cites a US peer reviewed study on home battery systems.
    Bottom line – unless the solar is export limited or would have gone to waste anyway it’s less efficient to store it in a battery and use it later. Something to think about eh?

  32. Doug Mcdonell on April 13, 2021 at 12:43 am

    The cost per kilowatt of storage is much cheaper with a hot water tank. Spending three thousand pounds to store 67 pence(4.8×14) worth of electricity in a battery is not a good idea.

  33. sdfglkjhdfkjdhldskfj on April 13, 2021 at 12:43 am

    Assuming no losses, 4.8kWh at 14p/kWh is worth £0.672. If your electricity is free and you successfully charge and discharge the battery 100% every day, then the total saving is 365*£0.672 = £245. With these very optimistic assumptions, it will take 15 years to pay off the capital cost of the battery. Domestic batteries seem to be a really bad move for anyone with a connection to the grid. If you are using them as an uninterruptible power supply then you need to keep them charged, so you will never discharge them: Their only benefit to you is in keeping things running if power goes out.

  34. Philip on Solent on April 13, 2021 at 12:46 am

    Would you still do this if you were installing today? Have you done an update to your install, I couldn’t find one in a search. Thanks

  35. Paul Edel on April 13, 2021 at 12:47 am

    I wonder which of the current worldwide fossil energy giants will become the Nokia of the energy world. With all the denying going on, in spite of everything being right in front of their eyes, that might make for a very interesting YouTube episode. I bet there will be more than one.

    The same thing can be said for the major auto manufacturers. It could be a separate episode or combined into one long one.

    Didn’t find this episode interesting but all episodes can’t be 🙂

  38. Gopidas K on April 13, 2021 at 12:50 am

    We invarably use pumps to fill overhead watertanks for consumption.
    Could you please think of a feature of this?

  39. paul K on April 13, 2021 at 12:52 am

    Thanks very much for producing this and making it easy to understand. It’s really important that as much focused action as possible is taken to de-carbonise our power generation. Around 50% of CO2 emmissions are linked to power generation(1). The optimist in me really hopes our actions will be effective in controlling climate change. Unfortunately the weather trends we are seeing are accelerating and I hope it won’t be too late. We need a bottom up and top down solution as always. More top down required on this one (China, Australia, America)

    2020 + 11 yrs will be the lowest solar activity in history. so the solar industry cant expand unless we turn the moon into a sun by nuclear explosions

  41. jabhip on April 13, 2021 at 12:53 am

    The big fire ball in the sky 1 million times larger than earth, the earths core made of molten lava and people talk about a trace gas being responsible for climate change, for the neutral observer it seems at best unlikely.

  43. Soubhik Dutta on April 13, 2021 at 12:54 am

    Has the economics changed now? like in india after subsidy we can setup a 3 kw system at approx 1.5 k pounds

    Its why it is critical we empower ourselves and take responsibility, great message subscribed!

  49. grindupBaker on April 13, 2021 at 12:58 am

    This is good because a "Lorne Mccuaig" who has studied the Arctic Ocean energy balance for years and has expert calculations has promised to give me 2 sets of his calculations so we can finally figure out this Blue-Ocean-Event (BOE) thing and stop just babbling about it. Isn’t that great. Several of you (certainly Mister Think) might likely have done these 2 following simple calculations yourself so you could let me know your 2 resulots please. I need +/- 5% or better to be any use as mine is all +/- 3% uncertainty. Thanks.
    Actually, you’ve clearly thought about this so you’ll be able to answer 2 questions I can’t get quantified since I been pondering it since August 2018. The 1st I might resolve but the 2nd looks really intractable. I computed +5 degrees for the Arctic Ocean surface (so -1.8 degrees late June warms to +3 degrees late September) if all ice is gone but I’m thinking maybe closer to 6 degrees. Questions for you to answer are:
    1) Did you use August 1996 Overview of Arctic Cloud and Radiation Characteristics by Judith Curry, William Russow, David Randall, Julie Schramm for clouds or did you use Trenberth’s global average 23% ? and how did you change these clouds with open water ? I’ve been pondering that for months. Give me your own calculations & I’ll plug them in. As you know that’s a massive 33 w/m**2 difference for the 180 days summer average insolation at 76N.
    2) The big one. As you know the entire Arctic Ocean is a massive 92 w/m**2 short on its solar radiation for the 180 days summer (when Sun is above horizon) to hold temperature as high as 0 degrees through those peak 6 months of warmth so the lower latitudes provide that 92 w/m**2 to make up the difference to hold Arctic summer temperature at 0 degrees (else it would plummet to -33 degrees through the Arctic summer. So how much of that 92 w/m**2 did you compute will be held back by the tropics to warm the tropics when the Arctic Ocean surface has warmed by a massive 6 degrees in a few decades ? That’s the one I’m really struggling with so just give me your own calculations that you’ve done for that & I’ll plug them in. Thanks.
    ps: I assume you used 20 m and Hadley mixing. Did you used 20 m and Hadley mixing ?
