EEVblog #724 - Home Solar Power System Analysis & Update

Dave looks at his 3kW home solar power system after being in operation for 18 months and analyses the results.

How much energy was produced?
How does net and gross metering work?
What is the payback period?
What is solar insolation?
The 3kW system uses 12 x 250W LG MonoX panels

  1. I love your videos, I have learnt so much from your research videos. Thank you very much for taking the time to research and make videos to benefit your viewers. Very much appreciated.

  2. I had mine installed in 2012 and we have a net feed in tariff which means the kWh's I feed into the grid gets deducted from my energy bill. Even in the Netherlands climate it is worth the investment. I'm past 75% on return of investment. It works baie goed! Thanks for the video.

  3. Hi, I am fron Jhb SA and have 1500 watts of panels(6x 250W Canadian Solar panels in 2 strings of 3 each in series) Have a Axpert aka PIP4048 and lots of batteries. My question is: Only have house lights on solar currently with max load about 250w. My panels do not show anything more than 755w max with 10A since install a month ago. Have been told that panels will not go to capacity or close to it because batteries have not been drained enough, would this stm be correct.

  4. We are finally building our home overlooking a small vineyard we've designed and now are bound to it. Full of clear understanding and guidance *[Awesome Plan Here >>>t.co/z2HakYxvSR ]

  5. Hi MJlorton! What a lovely video this is. Thanks for sharing. I would like to get an indicative figure, I mean how much it can cost me now to do the solar solution that you have in your home.

  6. Can we connect 5pv 100 w in series with 3pv 100w in parallel, any problem with the type ofconnection.?

  7. Thank you for sharing. I just found your videos and will be watching to learn all I can. Your explanations are very good. Best wishes, Linda

  8. Nice video. mine is smaller. I use 12kw per day. my panels bring in on a good day 9kw. it is cheaper to run it straight to grid. I also have 400 watts dedicated to 8- 6volt batteries (at)24 volts, that go to 2 dedicated lines in the house, 2 dedicated outlets that can be used if power outage. great savings. my electric bill has gone from 170.00 per month to about 40.00. I take what I save each month from power company and add more panels. I will soon have power company paying me. best investment I ever made. power company and all its employees hate solar, it cuts into their profits. my sujestion is they need to start building and selling and installing solar panels and keep their profits in clean energy.

  9. cheesus, what kind of demon posessed you to skip the batteriebank? you could have payed it back in like 2-3 years, including the batteriebank….

  10. I've seen that Google has some monster huge server farm facilities and solar panels.
    In that scenario why even bother to try to sell power to the grid at a low rate?
    Every watt hour their solar array produces just replaces what would have cost them the full rate from the grid.
    Would placing these on a gazebo or picnic shelter 20 feet from the house solve the firefighter problem?

  11. Piss poor install, dektites shocking. Rooftop iso screwed into panel. No. Conduit entry in the tops of all isolators

  12. Here in Sask Canada, we are charged 14 cents a Kwh but also basic charge and taxes so 500 kwh is 100 bucks or really 20 cents. You could easily pay off an electric water heater with the extra power your not using and put it as a pre-tank to your gas one. But without a battery bank to store and reuse your power when you need it your giving your savings away. over 7 years to pay off 5000 is pretty crappy. one day selling excess for 6 cents next day buying it back for 24 plus taxes sounds pretty ridiculous. I wouldn't want a system like that.

  13. I have used this [link here [Awesome Plan Here >>>t.co/WqSHhReOxS ] book since taking the train the trainer course using the same book and feel it does more to explain the things you run into everyday in the field.

  14. So wow my energy company for net metering only gives you 2.47 cents USD for every kWh when they charge 8.40 cents per kWh during winter or 32 cents per kWh (during peak hours) wow. I guess that this is what you get when companies have a monopoly

  15. .06 dollara doos!! can't you force higher pay rates like the power companies do? theres gotta be a way to get more money for the power u generate.

  16. Why not get a battery system? One would think that you would want something like that because it would pay for itself fairly quickly. Also, you could also set up a cryptocurrency mining rig to use the excess. It would be a complex setup, but you generate a LOT of extra energy, why not turn it into coins?

  17. I hаvе hаd оnе sitting оn thе dash оf mу Tоуоtа fоr a соuрlе оf уеаrѕ, and it keeps wоrking [ Check Details here ===t.co/HRqXnPbxqy ]. I’m ѕurе I will nееd tо rерlасе it ѕоmеdау, but I juѕt сhесk it аbоut оnсе a month, and put it bасk. Uѕе it when I nееd to. Wоrkѕ great!

  18. That meter cupboard is interesting. In the uk it'd be completely unacceptable to mount your own gear to the meter board. I'm guessing with this setup any additions mean removing that board to connect everything up? Can a general electrician do this? And those individual mcbs? Don't you have a distribution board?
