TOTAL RIP-OFF? 5 Solar Myths Busted! | ØY33

[@SmartEnergyLab]

Thanks Cory for setting the benchmark for high quality instructional videos for solar work. As a fellow content creator in the solar and battery space, I have been inspired by your technique and have learnt some new tricks... particularly with respect to the UK electrical code (I'm based in Australia). Keep it up... I'll be watching and learning. PS. Maybe Wetherspoon need to revise their "no fired egg" policy on cooked breakfasts, or did you order the vegan option by mistake?

I’m not an electrician but I work very closely with them. I have always been very interested in the trade. I really really enjoy how you bring the theory into what you do. Bringing in experts in the field to help explain how things work. The quality of your channel is right up there. It’s rhetorical first thing I watch when it appears in my feed. Keep up the great work. Looking forward to the next one.

Love watching your videos, they appeal to me and I'm not an electrician, although I'd love to have solar and batteries in the future, Cory - "I'm not telling how much ballast I'm using! definitely not two bags of ballast then!!! I'd feel a bit nervous if I had that setup that in a storm, especially by the coast that these would slide off the roof. Apart from the ballast is there anything that would stop this?

[@jk-8761]

The design is perfect. Exactly as I’d have designed it. Great video my friend. In the summer I suspect that is perfect, my advice… with that meter I’d avoid a feed in tariff and would instead opt to keep spinning it backwards and self consuming! Smart meters… when will the energy companies ever do something for you for free that benefits you? 😂

[@jacktissington]

£15k for a 12 panel with 10kw battery is very reasonable considering you also fitted a 3 phase board and used the pv ultra

[@RBcymru]

No calibration sticker on the Tester. I had a solar system installed and went for several 2.4kw batteries just in case one failed in the future so I can still use the others until the replacement is installed. I can add batteries at anytime. I would recommend a 5 or 6 kw inverter especially if you have an electric oven and induction hob. Nice commando socket added to your install, for an EV 3kw charger ?

[@adzie3229]

Great video Cory - I’d like to see more insights into your thought process when designing. Target export %, to balance efficiency vs cost, ROI, panel size etc. I know it’s not a huge consideration on a 5kW system but I bet you gave it some thought.

[@TheImhotep2012]

Just found this channel and already loving it. Great content and super funny but not patronising presentation. Double thumbs up. 😂. I'm just having roof solar fitted and the chimps who installed it mounted it east west on a south north roof. So, half the panels would never see the sun! Credit to the company, they have admitted the error and are returning to fix it. Consequently, this is a pertinent topic for me right now. Do please keep up the informative vids, and best of luck to you - you seem to be bucking the millenial trend and getting out there and doing it. Kudos. :-)

[@judebrown4103]

Oh my goodness Cory I nearly missed this. I'll have to warch some now and some later...here we go... Edit: well I caught up, I love how you manage to educate and inform your fellow electricians without being boring and raising a chuckle. That was fascinating about the earth rod impedence test (hope I've got that right!). As a lay person I have a question...were those mounting buckets really only held down with a couple of bags of ballast? No other protection from the wind..and dont they fill up with water? On the one hand it would lend extra weight but on the other hand there would be extra weight on the roof. I'm interested because I have a small flat roof which might take a few panels one day. Think I'd want to have some sort of bar across the roof and going over the side to be fixed under the edge. Fix the buckets to that so the wind has to not only pick up the weighted buckets but the roof as well! Very enjoyable video, thanks Cory 👍

[@9111logic]

Thanks for the info 🙏 - Are you bonding the Garage grounding electrode to the house earthing rod? I have serious doubts and mixed feelings about this subject as I have long distances between the generating area, the solar compartment and the house & outside buildings and in the event of lightening striking the soil in the area, there could be a vast differential of potential between the two grounding electrodes and we don't need that much of an imagination to see what could happen 😍 Have you been wondering that too ?

[@sidperry7748]

Hi Cory great video 👍 , watched all of it without skipping any , just one question, did it require planning permission to have them on that flat roof ?

[@sjdiy8230]

There is a rule change for solar panels from 21/12/23 as that as long as you do not exceed 0.6m above the flat roof (excluding the height of the chimney if present) it falls under permitted development in England anyway. See The Town and Country Planning (General Permitted Development etc.) (England) (Amendment) (No. 2) Order 2023 However not all properties have Permitted Development rights, conservation areas may require further permissions/restrictions, so do your own checks. Rules may also be different in the devolved nations.

It would have affected it to a greater extent, but thanks to the optimisers, its limited.

[@gadgetman36]

You must always "check all factory connections" on electrical equipment, whether domestic or commercial, as per the warning stickers on it. As the installer it's your responsibilty to torque them up correctly, and it's on you if they aren't, not the manufacturer.

[@Chris-Garrod]

Hi Cory, Do you ever just install the batteries and inverter without the solar panels to allow storage at a cheap rate, with the option to install solar panels in the future? Would this system allow just the batteries to be connected? Thanks for your videos, Chris (sparks in the East Anglia).

What angle are those panels? I thought 30deg from horizontal was optimum for grid connect? How do you work out the spacing between rows to prevent shading with low winter sun?

[@brendenpalmer9533]

Can you install a solar edge inverter and panel optimisers with an existing solar system or do the panels need to be solar edge also?

[@mnbvcx]

What exactly do you mean with the "German" System? Here in Germany most Households do have a three phase supply but then the power should also be distributed as evenly as possible. There are also some old houses with single Phase Power, but not many.

[@JC-jv5xw]

Surely with the earth electrode the critical thing is to measure the resistance back to the substation earth to ensure that there is a sufficiently low loop resistance to ensure safe disconnection. Surely it would be better to measure between the new electrode and the incoming PME earth, or just do a loop test using the new , disconnected electrode. What you appear to have done here is to measure its connectivity to the customer's lawn, which may be in the opposite direction and with different soil conditions. As well as wasting time with the temporary probe placements. And advertising a non-essential piece of kit.

[@corymac]

This is the proper method to carry out the test, with the process, and equipment as per Guidance Note 3. For a deeper dive into why, and how it works, feel free to check it out for yourself in GN3, and whilst you’re there, also Guidance Note 8. Thanks for watching! 🙏🏼

[@JC-jv5xw]

@@corymac Thanks Cory. Of course the main thing is to ensure a good path between protective casings and the nearby ground (Timmy's Terra?) to minimise error potential. The loop resistance is to ensure safe disconnection of the fault. Perhaps the regs place too much emphasis on the loop resistance, causing us to forget other things. Such as neutral connections.

Great video Cory ! Terrific job on the install. Really like that you went for thick 16mm cable. The console tubs are an interesting solution to tilting the panels. My panels were tilted with aluminium legs and frames. I think I like my aluminium tilts better, because I'm in a cyclone prone area and I like things bolted down. I love my solar which was installed in Aug-2023: solar panels on my roof and a grid tied inverter (no lithium batteries for me). This was my 3rd solar panel installation, each at a different property. Also have an old Solar Hot Water System (HWS) on my roof - which produces more than enough hot water for my needs, even after days of overcast / rainy weather. My power bills have turned into credits, and I now get free electricity and make around $100 per month tax free - a whopping 25% Return on Investment (ROI). It's like having a piggy bank on my roof. Highly recommend others do this if they can. Use a reputable, quality installer - like Cory, and always do your research first.

These plastic tubs are a bad solution. Because every tub can move separatly it needs way more ballast to stay in place. Also the panels heat up more because lack of airflow behind them and will generate less power. I dont think there is enough ballast there - did you used the Renusol PV-Configurator?

That's what basically everyone else has done when self installing. It's important to remember that they are not asking that question to check the quality of installation, cause even qualified sparks can do some god awful work. But they want notification of what's hanging off the end of their service head so they know who to talk to about the installation, and so they can plan network upgrades in the future. If they know they know how many homes can dump power onto the grid, they might have to limit new people applying down to a lower maximum export, or spend big money increasing capacity so you don't get those homes backfeeding the substation.

[@tomsgrinbergs8020]

47:40 why would you want it to be clipping, even with the battery? Say your solar pv panels can at that time output 4kw, and the battery is full, why would you limit yourself? Octopus export tariff today is around 17p/kwh, so it is kind off worth exporting these days. Love this long style of videos from ya m8, watched it all the way through, when are ya going back to Norway or maybe some other work in Europe so we can compare how things are elsewhere please?

[@corymac]

That’s part of the calculation, you hope that with a correctly sized battery, the clipping is minimal, and it is better to have the inverter running efficiently at its namesake all year vs a few extra KWh a year and a less efficient inverter

[@tomsgrinbergs8020]

Oh, so say at 2kw inverter has a lot of losses inverting the DC to AC, whereas as at full tilt it does not?

[@tomsgrinbergs8020]

Thanks for the mega quick reply by the way!

[@edc1569]

Clipping makes a lot of sense in terms of grid planning, the grid would much rather you exported over a longer time frame than be all peaky and syncd up with your solar neighbours.

[@mikebarry229]

Clipping makes sense when you have an export limitation....If you have 3.67kW export limit and only 3.67kw of panels that might be fine in the summer but when there is less sun about even 5kWp of panels wont produce that so over sizing the panels and accepting clipping in the summer means you get maximum output for longer
