40 Responses to Solar Panels – The Easiest and Cheapest Way to Encapsulate DIY Solar Panels

  • gconol says:

    Interesting way of encapsulating the panels, but I’m worried that this film
    will melt under the extreme heat from the sun. Those panels get really hot
    on summer days.

  • Tobots Wholesale says:

    I would reverse engineer a proper solar panel, seem to be a thing on
    youtube to find the best and cheapest way to “Encapsulate” solar cells.
    This is very cheap and i doubt it will work very well in baking sun. 

  • Glenn Hough says:

    very interesting, thank you for sharing been wondering how to do that… I
    never thought that its so easy.. great job!

  • Jason Bryant says:

    how about actually SHOWING the process….you skipped over everything… :

  • john strange says:

    Last winter I built 2 – 70 watt solar panels using eva film, It worked
    pretty good. I also bought some backing for the panels, but really dont
    know how to adhere it to the back of the panels. Do you have any Ideas?
    This year Im building a solar panel using the glass from an old storm door.
    It should be in the 100 watt range.

    Can;t believe there are cheap solar panel that we can use. Thanks for the

  • SurvivalGearnMore.Com says:

    This is the most efficient way I`ve ever seen.Did you sandwich the cells
    with the EVA or did you lay the EVA on the back “positive”side of the cells?


    Good video, eva is an excellent option. UV is very good. Great video, Thank

  • w3bguru says:

    Thanks for that link – that EVA + a heat gun looks like a great, easy, and
    cheaper encapsulation method. Thanks.

  • Glenn Hough says:

    please tell me where did you purchase your solar cells.. thank you..

  • flamedrag18 says:

    instead of this…..couldn’t you just tape the panels to the glass and
    continue taping them until you get it all covered with tape?

  • Green Tester says:

    check on ebay for EVA Solar Cell Encapsulant Film…

  • ShySkyBros says:

    I’ve added a link to a page that has more info and prices for EVA film and
    Slygard. Please check the video description for the link.

  • horsemonkies says:

    I notice that there are small air bubbles that are on the cells. Wouldn’t
    that cut down the life of the panel significantly?

  • rhooie says:

    I never thought of using bed liner. But it sounds like it would be
    completely water proof. I already have a roll of EVA. I tried it with a
    layer on the glass, then the cells, then another layer of EVA and a layer
    of TPE. I used a heat gun, but you can’t really get all the bubbles out.
    This video shows just a layer of EVA on the back. Actually makes more sense
    to me. The glass in front of the cells is water proof. Why use 2 layers? I
    think I will just use 1 layer on the back on the next panel.

  • rhooie says:

    And you have panels like this that have endured the test of time?

  • rhooie says:

    I subscribed. Looking forward to it. I like the idea of the half panels. I
    have a bunch of cells I am hoping to get to as well. I have 72 plus in 3 x
    6 and also 5 x6 I have had around a long time waiting for me to get too.
    You said you use standard window glass? The last panel I made I bought
    tempered glass 1/4″. Very heavy to move around. I just worry plain window
    glass would be fragile. Does the fiberglass screen strengthen it up nicely?

  • vta1985 says:

    I pronounce it sillyguard.

  • ingesumadre says:

    would that hold to the intense sun?

  • SurianoSales says:

    I am searching for the best EVA aplication. Have you found it better to go
    with glass, solar cells then EVA? I dont know which is better way to go as
    some are going glass, EVA, Cells,EVA then a backing of some type. Plenty of
    videos just showing the heat gun process. We newbies also need to see how
    you deal with the wires coming out through the EVA. Your video is one of
    the best for showing heat gun use, Thanks.

    The sun is not infinite it will burn out just saying

  • TheBarOst says:

    what does “almost electron” mean 1:40???

  • Joe Dokes says:

    Um… No. The sun provides one kilowatt of energy per square meter, not
    1000 kilowatt/hr per square meter, on the earths surface . . . when in the
    sun, on a clear day, when the sun is directly overhead. And, 1000 liters of
    fuel oil provides over 10 Megawatts/hour of energy. So the sun only
    provides one ten thousandth of the fuel oil energy you specify. Put
    another way, you need 10,000 square meters of solar panels running at 100%
    conversion efficiency to get the same power as the oil. If the solar panel
    has an efficiency of 10 percent, then you need 100,000 square meters of
    solar panels.

    What was the purpose of bashing the oil industry at the beginning of this
    video? I am in the oil industry and happen to know that the some of the
    most significant investments and innovations in renewable and clean energy
    come from large oil producers. Energy is energy, and the oil and gas
    industry is smart enough to realize the potential in all areas of energy
    production. You cheapen your effort making this video with childish pokes
    at the “bad guy” that you see in oil and gas. We wouldn’t be where we are
    without it and certainly wouldn’t have the resources to evolve new
    technologies without fossil fuels.

    Solar Power Systems – How Do They Work?

    Solar power is a form of renewable energy that can be put to use almost
    anywhere you live. Harnessing the sun’s rays can be done in many ways, but
    the most common method is to use solar panels to generate DC power that can
    either be used directly or stored in batteries for use whenever you need
    it. The components that convert the Sun’s energy into electricity are known
    collectively as solar power systems.
    Converting the sun’s energy into electricity is done by something called
    the photovoltaic process. A solar cell is made up of a couple of thin
    slices of a substance called silicon. One layer of silicon is given a
    positive charge while the other is negatively charged. When sunlight shines
    on the solar cell, some electrons are knocked loose and travel from one
    side to the other. By connecting contacts and wires to the solar cells, we
    can collect the current generated by the movement of these electrons, using
    it to power items such as calculators and watches, or storing it for use
    later on.
    Solar cells produce what’s called DC current. A few devices can use this
    kind of power, but most appliances in the home use AC, or alternating
    current. A device called an inverter is required to change the DC power
    generated by your solar system into AC power that most appliances can use.
    An inverter is an important piece in your overall solar energy plan.
    Batteries are vital component of and “off-grid” solar power system but can
    also be included in a grid-tie solar system. collect the power, but require
    some place to store it until it’s needed. There are many different types of
    batteries to choose from, and each type has its advantages. For instance,
    some batteries last longer and are less expensive that others, but they
    require regular maintenance, while others are sealed and are said to be
    maintenance free. Be sure to choose the right battery for your situation.
    Another important piece of the solar energy system puzzle is called a
    charge controller. Charge controllerswork to regulate the amount of current
    and voltage being transferred from your solar panels to the batteries.
    Overcharging of batteries can lead to a reduced life span and may also
    completely destroy the battery. A good charge controller will ensure that
    your solar power system is operating at peak efficiency.
    There are basically two different types of residential solar power systems
    you can install for your. One is called a grid-tie system. This type of
    arrangement is will generate power for use in your home and then deliver
    the excess power back to your utility company. Typically, the power
    delivered back to the utility company can be used to offset your monthly
    utility bill.
    Off-grid systems are just as the name implies. They are completely
    independent of your utility company and use batteries for storage of all
    the electricity that’s generated. These are sometimes also called
    standalone systems.
    Solar power is a clean, quiet, and environmentally friendly way to reduce
    the cost of your utility bill while reducing your carbon footprint at the
    same time. Investigate your options and take advantage of the abundant
    energy of the sun.
