  1. Finally!!! Someone put it together. I really appreciate the video’s. They explain many questions of “How To” I have had. Hope to see more later. Thank you ever sooo much.

  2. I second the thank you for the videos. You’ve done an excellent job. I look forward to seeing the rest.

  3. You are AWESOME!!!!!!!!!!!!!!
    Thank you very much for presenting all of this information for free!!!!. I have been doing a lot of research and wasting alot of time until now. You put everything together for me in a clear easy to understand style, and now I can finally get started building my own solar panel from start to finish!!!
    Thank You.

  4. hi! i have a advanced question (i tink myself) how many kg Watt hours its made with your solar panel. you can also give me a way to figure it out.

  5. Mr Rober

    .. Great job for helping us. can you e mail me where I can buy the frame aluminum completed with glass. I’m breaking so far 17 cells after i solder 24 cells. the wood is not great for our roofs. with your help we can get the frames website. also I need help if i want to make a 175 watts to 200 watts. wich cells do you like best. send me the websites
    thanks . franco

  6. follow up with my notes…. Mr Rober , where i can get a website like this one. is it costly.
    need advise.

    How much do you spend in all the materials to make the 60 watts panel.
    I want to start asap in my 175 w to 200 watts as soon as you can send me the website to buy cells and the frames. thanks again franco

  7. Hi Frank,

    I’d be glad to try to answer your questions, but register here on the site and submit your question in our Forums ( , that way if someone else has the same similar question, they can view it there as well.

    It helps us to tackle the problem of having to answer the same question/s over and over…


  8. Thanks for the video. You are a good person. Question: What was the total cost of building your solar panel and how does that cost compare to a purchased solar panel of equal characteristics?

  9. Hi Timothy,

    Thanks for the comment. As for the price, it cost about $400 – $500. I still have all the receipts, but just haven’t gotten to that part of the video, so I really haven’t updated the site with that information yet, but will do soon.

    And yes, a 63 watt commercial solar panel would cost alone $400 and up, so you are saving by building it yourself, as remember that doesn’t include the battery I had to buy plus the charge controller and other electrical devices.

  10. Great job Robert, glad you went out on a limb to make the videos. Can’t wait till you post more. Again Great Job!

  11. Thank you so much for sharing. I bought the earth 4 energy video and it doesn’t talk about the spacers. What a great idea. I wanted to know about cleaning the panels before you mount them onto the peg board. I saw another video of a factory and the wash the cells with ionized water I believe. Do you know anything about that? Again, thank you for the good work.

  12. Hi,

    Thanks for the comments. As for cleaning them, I would think your manufacture should already send you clean solar cells, at least most vendors on the net I believe would. But as far as what to use I’m not sure about that.

  13. Robert, what a wonderful website you have. I found you from Planet Green with the DIY Projects. I am a grandma with very little experience making anything except household items. I have been searching for any info to help me be a more responsible person with energy plus to help my budget. As with most seniors I have a small fixed income so this will be the only way I will ever get solar panels. God Bless you for being such a giving young man…I know your parents are so pround of you. I also have a grandson who is just getting ready to start college for Mechancial Engineering Degree. I am very proud of him and I feel with young men like you and my Anthony we will have some awesome men to carry on for the future.

  14. Robert, great site! I plan on visiting you on a regular basis. I had tried to build a panel by viewing another site and it didn’t go well. So I plan on watching all of your videos and then starting. Again thanks for you hard work.

  15. Dear Robert, Like others I really enjoyed your videos. I followed you until final part where the inverter is hooked up. What size is good for 63 watts and what can you run with it, like small frige or other things except lights. What kind of battery are you using one or two and why.

    thanks for your excellent work.

  16. Hi zeta110,

    Thanks for your comments. If you can buddy, open a thread for this in our forums as I’m sure others have the same questions you have, and I’ll be more than happy to answer your questions there 🙂

  17. Enjoyed your video – and took notes on the lecture about ohm’s law. Currently – “No Pun”, we are building from the same plans, DIY green energy. 36 Everbright cells = 18V Same dimensions and cells but methods are different. I will look up the spacers 1/4 inch? at Home depot to make the template for non tabbed cells that you have demonstrated but so far have built 9 panels 36 cells x 18V with tabbed cells all with standard benchmark results. Using PVC board for the sidwalls – instead of wood. The substrate is 1/2 inch laminated silver foam from lowes on 1/8th inch plywood. The frame is painted twice with flat white latex. Everything is drilled and glued with silicone and a screw every 3 inches. Lens cover is polycarbonate lexan from Bayer. – am thinking this is better than wood alone from easy to work/ cheap materials. Faster build? – so far running a 3000 watt inverter with 6 deep cycle 12V x 200ah marine batteries. Can run any tool I wish in the backyard shed. – looking to plug in a 490 watt airconditioner this summer.
    Good work on your video posts.

  18. I live in africa, below subsahara, electrcity is expensive and not always there we have a lot of sunshine going to waste. I have being searching for a way to build solar panal cheaply and came across your site. I have tried watching the vedio but the electricity supply is so unreliable that i have not been able to finish the part 1 in almost 2 weeks. Is it possible for one to get the guide in text form, either electronic or hard, or is there any other way people with my kind of problem can be ass isted. thanks a lot for trying to assist others

  19. please can you send me the picture after i finish my 36 cells buil i do’nt how i put togeter the tabbing and betwen. thank you. pedro.

  20. Hello,just discovered your Blog when i google something and wonder what webhosting do you use for your website,the speed is more faster than my blog, i really want to know it.will back to check it out,thanks!

  21. Hi, robert I like your videos very much specially the final part. What things do you run with such 63 watts.

  22. Hello,
    I have been reading about the use of bypass diodes in panels to prevent damage to cells when they become shaded. The diodes allow current to pass, going around the shaded cell/cells.
    How should these be installed? How would one descide what size bypass diode to use? Thaks

  23. I thought the positive and negative weren’t supposed to touch, but they’re connected at the bus wire on your video.

  24. They aren’t, but it may appear that they are. The bottom side is the negative and the top side of the cell is the positive. So the bus wire is just connecting the bottom or top of one cell to the positive/negative side of the next cell in the next column.

  25. hello,
    i am final year student and i have to work on solar tracker it is also my project so give any simple idea about solar tracker and i have to make this project in 15 days so please reply.

  26. Hi Robert, Hope you still read these. I watched the video’s with great interest, and now feel comfortable attempting to build my own system. My goal it so power a 40 gallon 220 volt hot water heater though. Two element unit with each element at 4,500 watts. Now…perhaps both do not come on at the same time, and I’ll have to research that one with the wiring of the unit. But am looking to confirm my thoughts: about 2 to 3 batteries, 2 panels with charger, meters, etc….and then running a timer to a relay that powers it on/off for about only 2 hours a day. Am I on track with my needs?
    Thanks and hope to hear from you. Great stuff you have done here. Regards, Terry

  27. Recently I’ve been directing everyone to the following forum for support since I do not have a lot of free time:

  28. Has anyone ever told you the reason you have a problem soldering is your iron tip really needs to be CLEANED ! A tip should never look like that, take a fine file and file all the dark off of it then give it a dab of flux then touch silver solder to it, that will “tin” it. To keep it clean, after you use it each time, wipe it on a damp sponge and from time to time give it a dab of silver solder.
    You will find it easer to solder to the back side of the solar cells, the side with the 3 “dot tabs” in a row if you give them just a little silver solder first and then put the tab wire on.

    In your video you used what are called ” crimp on ” connectors, I NEVER use them because over time they will come lose >unless< you also give then some solder

    In your video, the one where you take us into the class room, you are talking about OHMS LAW, and you use the letter V for volts, I am an engineer, OHMS LAW does not use the letter V for volts, it uses the letter E for volts. E for volts, I for current and R for resistance in ohms, Do you know the unit used for conductance ? it is the MHO 9 ohms spelled backwards)
