DIY Solar Panel Power from 80 WATT SOLAR PANELS to a Grid Tie Inverter

DIY panel solar training for solar panel connections. Off Grid options for DIY and Green Jobs Training for solar installation of panels.
This is a Monocrystalline Solar panel rated at 80 watts. This panel in direct sunlight can power a GTI Grid tie inverter providing 63 watts AC alternating current supplementing the power consumption from the electric company grid. The GTI is a 200 watt version. 3 panels would be needed in parallel to run direct at full power.

    Hey Dan! If I get a grid tie inverter (what kind should I get?), can I add 1 solar panel at a time as I get them?

  2. mptrax on April 7, 2021 at 11:46 pm

    UNBELIEVABLE ! The Italian turd politicians taxed solar panels !!! INSANE !!! in the modern EU !!!!

    thanks 4 this video, i was thinking bout maybe joining sum trainning classes, do u work doing this?

  4. GREENPOWERSCIENCE on April 7, 2021 at 11:47 pm

    @cm4english For GTI you need about 20% more panel watts than the inverter rating. For a backup you can use any panel but your battery charging time will be determined by the battery Amp Hours, Current Charge, and the watt input from the panel.

    In regards to 300 watts? They would be watt hours if on for one hour.

  5. GREENPOWERSCIENCE on April 7, 2021 at 11:47 pm

    The GTI will have an IN voltage range DEPENDING ON THE MODEL. Your panels in SERIES:
    ______(+-+-+-)_____ = 36 VOLTS @ 4 AMPS 36volt X 4amps=144 WATTS
    produce higher voltage and the same amperage as a single panel so 2v12v panels can be used for a 20-50 volt gti.
    For a 12-21 volt GTI single panels wired in PARALLEL
    ——-(+++—)——- = 12 VOLTS @ 12 AMPS 12volt X 12amps=144 WATTS

    This explains:

    GTI no batteries

    regular inverter batteries + charge controller grid free.

  7. jawbraeka on April 7, 2021 at 11:51 pm

    @GREENPOWERSCIENCE why not buy 1 after the 2.5 year mark then halving the cost of the 2nd panel and effectively saving you 2.5 years?

    buy 4 and you effectively have them for free. large upfront but less time to pay off 4 panels = 4 years = all paid off.

    When solar panels get to 1$ a watt… this will be a HAPPY day for me :]

  9. OBXSOLWIND on April 7, 2021 at 11:53 pm

    mono or multi crystalline are the most effcient when they experience no shading thats why they perform better when wired in paralell. amorphous pannels work better when shaded in part but they loose huge out put when they get hot. I hope I answered your question. Great vid dan. CHEERS WINDY NC

  10. GREENPOWERSCIENCE on April 7, 2021 at 11:54 pm

    @cm4english You would need a 1000 watt REGULAR pure sine inverter and 3 deep cycle batteries to run a fridge and a few lights for 5 hours. A GTI is no good for blackouts. They shut off. You could charge all 3 batteries in about 3 days with a smaller panel. That would be for backup only.

  11. czarsolarhydrowind on April 7, 2021 at 11:55 pm

    @GREENPOWERSCIENCE Dan, I’ve watched all of your vids, when are you gonna show us the system that you use for your home? I’m shure with all this stuff your learning you have one up on the power company….Thanx Czarsolarhydrowind.

  12. Bryan DaSilva on April 7, 2021 at 11:56 pm

    Im sure I can power my car battery with this single panel.

  13. ShawnHydedotcom on April 7, 2021 at 11:56 pm

    You can get 100-150 watts worth of these cells for $80, but they are not the best

  14. Mike ö on April 7, 2021 at 11:57 pm

    What kind of Grid Tie inverter is this? 200wattt? 12v or 24V?

  15. lancerooke on April 8, 2021 at 12:00 am

    How many monocrystaline cells make an 80 watt panel? And is there a way I can wire my polycrystaline cells in parallel so I can increase the wattage? I was thinking of wiring 36 cells in series and then doing the rest in parallel. Will that work? And if so… how do I do it?

  16. GREENPOWERSCIENCE on April 8, 2021 at 12:01 am

    @randywest6 Pure sine or modified sine inverters have 12v posts OUT and IN. Grid tie inverters have a female computer AC plug 3 prong hole out for a male out. And only one red black in. The usually say Grid Tie on them. NEVER hook a pregular inverter to the grid power, it will blow up.

  17. pcguys-off-grid-cabin on April 8, 2021 at 12:01 am

    Do you have to use some sort of charge controler with a grid tie and no batteries?

  18. solaris3000 on April 8, 2021 at 12:03 am

    Hello Dan,, In your example you are using a panel rated at 80watts that yields 63 watts back to the grid. In my setup I have 2×125 watt panels and 1×85 for a total of 335 watts rated.
    The problem is I am only yielding 120 watts back to the grid as displayed on my watts-up meter, Why is the yield so low. This reading was at 2pm no clouds in sky, I am losing around 50% or more and its very frustrating… Please help… Thank you,,,,

  19. GREENPOWERSCIENCE on April 8, 2021 at 12:04 am

    Sorry for missing this.

    Materials are a small impact. Consider one panel removes about 700 pounds of deposited coal ash and several tons of co2
    The goal $ to think about a car. When you buy one, most do not ask "when will it pay for itself." Consider 15¢ a kwh. Each $250 (80 watt panel) will produce about 1KWh on a good day.$4.00 a month $40 a year rounding down. 5 years to flat.
    If instant savings is the goal, consider Energy efficient appliances. They are the first step towards solar anyway.

  20. miscitalia on April 8, 2021 at 12:07 am

    I would like to be able to put solar panels in my apartment windows…do u think that would be possible???

  21. J S on April 8, 2021 at 12:07 am

    is that a Siemens panel?

  22. kenmorto on April 8, 2021 at 12:11 am

    An eagle turd from that altitude could be fatal to one of those panels!

  23. Jeff Benefield on April 8, 2021 at 12:12 am

    @DjGisME But it does make sense to generate your own power, just not to save the earth.

  24. GREENPOWERSCIENCE on April 8, 2021 at 12:13 am

    Thank you:-)

  25. capitaindouleur on April 8, 2021 at 12:16 am

    I would like to know what kind of panels are the most efficient.

  26. Bobby b on April 8, 2021 at 12:19 am

    everywhere im seeing a panel is almost $2 per watt…..that is still insane pricing.

  27. Mark Cam on April 8, 2021 at 12:19 am

    Thanks for the xtra treat while filming …..I have never seen birds before 😉

  28. solarman on April 8, 2021 at 12:20 am

    GREAT VIDEO. Watched your other solar pnl videos. Just finished making my 4 pnl and using Grid tie Inverter to feed power back into my home. DIY cost is running 1/2 . Doubled my wattage with roating my last pnl with the SUN. Could not do it without your videos. THANKS.

  29. davevanden1 on April 8, 2021 at 12:20 am

    high Dan
    please look at my video on solar panels.
    just want to show you what happens to cells if they are not mounted to the glass properly just for you info or so if people ask you they get the proper info on building these things

  30. bigblue649 on April 8, 2021 at 12:21 am

    80 Watts x 5 Peak sun hours x 365 days in year x .75 system efficiency= 109.5 KWH a year. 109.5KWH x .15 cents a KWH=$16.42. Now the price of the panel is 250 so 250/16.42=15.2 years to pay the panel off, not including the inverter. By the way any inverter that you grid tie has to be UL listed as a interactive inverter which the one that is used is not. Plus this way of connecting to the grid is illegal, we have the NEC for a reason. All i have to say is just please be safe!

  31. Don 351w on April 8, 2021 at 12:22 am

    I have heard that plug in grid tie inverters are not legal, do you know if this is true or not?

  32. roidroid on April 8, 2021 at 12:24 am

    those birds look so chaotic, like leaves blowing in the wind

  34. Robert Messer on April 8, 2021 at 12:26 am

    Hello great videos you have. Can you tell me what you would recomend for me, I just built a cabin for my family to go to on top of a small moutain and we would like to build something that we can run lights for the small cabin and possibly run our laptop and or small tv and dvd player for our kids because we plan to spend months on end up there and we do need a small amount of electric up there other then a generator. It is next to lake erie so wind is there, and we have a small budget thank you

  35. fight4yourfreedom1 on April 8, 2021 at 12:26 am

    does it matter what size inverter you have. a 1000 watt inverter with a 90 watt panel??

  36. 12oscar12 on April 8, 2021 at 12:28 am

    what happens if the birds poop on the panels

  37. Jonathan Starnes on April 8, 2021 at 12:28 am

    Hey I have a 12v battery and based on what I’ve heard 6v golf cart batteries are the way to go I only have about 100 watts of solar but can I have 2 golf cart batteries 12v and 1 12v battery until the 12v dies then have only 6v batteries

  38. Shariq s on April 8, 2021 at 12:30 am

    what would happen if you dip a small solar cell in water and place it at the focal length of a frenel lens
    i think the solar cell is not going to heat up and you could get more voltage

  39. Munna Bhai on April 8, 2021 at 12:30 am

    80 watts solar ka

  40. Munna Bhai on April 8, 2021 at 12:31 am

    RS. kitna parta hai

  41. capitaindouleur on April 8, 2021 at 12:32 am

    @OBXSOLWIND Thank you.

  42. ispixxxxx on April 8, 2021 at 12:32 am

    I like the way you look around, and give extras to us also. Like the birds in the sky.

  43. Michael Shelnutt on April 8, 2021 at 12:33 am

    I doubt there would be 12 hours of production. Most places are only 4-5 hours per day.

  44. GREENPOWERSCIENCE on April 8, 2021 at 12:33 am

    @GREENPOWERSCIENCE over used life, also can be recycled.

  45. Mike P on April 8, 2021 at 12:34 am

    Another great video! Can you hook up two then three in parallel to the grid tie? I am curious to know what the "sweet spot" is with these plug-in type inverters.

  46. bob oso on April 8, 2021 at 12:35 am

    Love your vids…been watching for years and learning a lot.
    Ken from Az.

  47. SamytheGreek on April 8, 2021 at 12:35 am

    Do I understand correctly that with a grid tie panel you connect to the inverter directly without having to use a battery, but the other kind of cell charges a battery and the power you get is from the battery that has an inverter that you can plug into?

  48. GREENPOWERSCIENCE on April 8, 2021 at 12:38 am

    5 years

  49. GREENPOWERSCIENCE on April 8, 2021 at 12:40 am

    No, direct.

  50. Mike P on April 8, 2021 at 12:43 am

    Math is a little off as a 80 watt panel and assuming a inverter with 100% efficiency would have to run for over 12.5 hours to produce a single KiloWatthour of electricity. 1KWh equals 1000 Watthours, 1000 / 80 = 12.5 hours. Please correct me if I am wrong…
