Buying pre-soldered tabbing wire will cut some steps out of the process, but you will still need a soldering iron to solder the wiring to the back of the solar cells and string the wire correctly to connect the solar cells.

Non-conductive material to attach the cells to, like wood, glass or plastic

For DIY solar panels, wood usually works best as backing because it is easy to drill holes for the wiring. Once you have your solar cells wired together, you can glue these to the wood backing and then attach all of the wires and solder each solar cell together.

After wiring, you then connect these wires to a charge controller, which regulates the volts of energy. Wood can also be used to build a box to protect the solar cells and then to lay the plexiglass on top for moisture protection.

Seal the solar panel with plexiglass

Once your solar cells are wired and glued to the wood backing, you need to seal them with plexiglass for protection from heat, debris, and moisture.

Is Making Your Own Solar Panel Advisable

Many have engaged in the world of solar energy as it is easily accessed with only the rays of the sun in a specific area. Nevertheless, some homeowners consider the possibility of conceptualizing and building these panels from scratch.

However, it is not impossible in fact, many have attempted to do so to keep track of the cost of production and modification depending on preference.

In considering doing your solar panels by your own, these factors should be kept in mind:

  • Efficiency of construction
  • The longevity of the DIY solar panels
  • Cost and Financial route
  • Warranty of the materials

Moreover, keep in mind that there are right and wrong angles of perspective and scenarios in the process of conceptualizing the solar panels by yourself.

There is a lot involved in various solar installation and its benefits. At the same time, drawbacks are there. Bear in mind in the process to have a step ahead in the progress of construction.

Which Type Of Solar Panel Is Best For Your Diy Solar Project

There are three major types of solar panels available for residential projects.

Monocrystalline solar modules consist of 60 or 72 solar cells made of silicon uniformly black in color covered in glass and framed in metal. Each cell has rounded white edges. Monocrystalline panels are slightly more expensive than other types, but considerably more efficient. They convert up to 23% of sunlight to electricity.

Polycrystalline solar panels also contain 60 or 72 solar cells, each one perfectly square in a mottled blue color. They convert about 15%-17% of sunpower into usable electrical energy. Polycrystalline panels are slightly less expensive than monocrystalline modules.

Thin film solar cells are lightweight and flexible sheets of a photovoltaic material applied to a solid surface like glass. Thin films are even less efficient than the other types, usually only 10-13%. They are also cheaper.

The Procedure For How To Make Solar Panel At Home

Those curious to find the answer for how to make solar panel at home, you will get the solution here. The first step is heating a copper sheet.

For that, first, you need to light up a propane torch and hold it in one hand. Always remember to use the propane torch in strict accordance with the safety directions given by the manufacturer. Next, you need to pick up the copper sheet with the other hand with the help of tongs.

Further, hold the copper sheet in the flame. You will have to keep heating the copper for at least a minute until the fragment under the flame has been glowing red hot.

After that, set the sheet of copper down only on a fireproof surface. Then again, pick it up using tongs and hold a different section and heat the new area with that torch.

Keep repeating this procedure till completion of treatment of different spots. After that, keep the sheet on a fireproof surface and allow it cool to air temperature. You will notice the heated areas have now turned black or of any other colour.

Subsequently, we need to prepare our first wire. For that, you have to strip one inch of insulation of each of the ends using wire strippers. Clamp the one end to the sheet of copper with the help of an alligator clip. Ensure you clamp it to fresh and un-blackened copper.

Planning The Panel Wiring

Every solar cell has a positive and negative lead . They are marked with + for positive lead and for negative lead. The face of the solar cell is the negative side, and the back is the positive side.

Solar cells are usually connected in strings. In the example given below, each string consists of four cells, and the panel consists of five strings of cells connected together.

Cells can be connected in two ways:

  • Cells in strings can be connected with each other in series which adds the voltage of each cell
  • Cells can be connected to each other in parallel adds current of each cell.
  • See the picture below for the difference between series and parallel connection.

    Cells Connected In Series a string of four .5 volt 2 amp cells connected in series will have the output of 2.0 volts, and 2 amps at the end leads. To connect cells in a series, connect the string from the back of one cell to the face of the next cell, and so on.

    Cells Connected In Parallel The same four cells when connected in the parallel can produce 8 amps and 0.5 volts. To connect cells in parallel, join the faces together. In order words, the positive side connect to the positive side of the next cell, and the negative side connect to the negative side of the next cell.

    By Step Instructions On How To Make Solar Panels

    Safety First

    When making solar panels, always wear a mask and safety glasses during soldering to protect from the inhalation of fumes and from flicking solder.

    Also when you build solar panels, always make sure, you wear gloves during the handling of solar cells so you don’t get oil on the cells and reduce their effectiveness.

    Assembling Your Solar Cell

  • 1Squeeze 1-2 drops of an iodide electrolyte solution onto the dyed glass slide. Gently place the dyed glass slide stained-side-up in front of you. Use a pipette to squeeze 1-2 drops of iodide electrolyte solution onto the dyed coating.XResearch source
  • If there is any excess solution near the edges of the slide, where there is no dyed coating, wipe it off with a clean tissue.
  • You can buy a bottle of iodide electrolyte solution online for about $30 USD or less.
  • 2Offset the carbon-coated slide, graphite-side-down, on top of the dyed slide. Carefully pick up your graphite-coated slide by the sides, without touching the carbon coating. Flip it over on top of the dyed slide and offset it so that the strip that you didnt cover with graphite is exposed on 1 side and there is a clear strip of the dyed slide exposed on the opposite side.XResearch source
  • These 2 conductive faces of the slides, sandwiched together face-to-face, form the inside of your solar cell.
  • 3Clip the slides together at the 2 non-exposed edges using binder clips. The exposed edge of each slide is where you test the solar cell, so dont put the clips here. Carefully clip the slides together at the 2 other sides where the plates are sandwiched together with no exposed edges.XResearch source
  • This is your completed solar cell. It will work until the electrolyte solution evaporates, at which point you can unclip the slides and add more solution or simply squeeze more solution onto 1 of the edges and let it seep in.

    Powder Coated Solar Panel Frames

    Solar panels comprising of a powder coated aluminum frame are ideal for those who prefer style over function. Most frames of this type come in black and blend in better with dark roof tiles. They can, however, come in a wide variety of colors to match different elements of a new or existing building. You can even achieve either a gloss, matt, or satin finish with the powder coating technique.

    The main drawback with powder coated solar frames is that they scratch more easily than their anodized alternatives. The benefit here though is that you can repair powder coated materials, unlike scratches on anodized aluminum frames.

    Step 1: Cutting Out Your Panel’s Front and Back Sides

    The first step in making solar panels involves cutting out your solar panel’s front and back sides.

    The front of your solar panel will consist of a sheet of clearacrylic.

    The back of your solar panel will consist of a sheet of white acrylic.

    Note: This material is perfect to make solar panels with because it is weather proof, corrosion proof and durable.

    You must cut your pieces of clear and white acrylic to the exact dimensions of your solar panel.

    So how do you figure this out?

    It’s simple, whatever size of solar cells you use, you must measure them out and multiply their width by 4 and their height by 9. This will give you the approximate width and height of your two pieces of acrylic , but don’t cut yet.

    You must first make sure your measurements include about a 1/4 inch of extra space in between each solar cell .

    Also leave about 1 -2 inches of extra space between the outer edge of the solar cells and the outer edge of the entire panel to allow space for the aluminum frame .

    Let’s put these two “cut” pieces of acrylic aside for now and continue learning how to make solar panels.

    Link The Circuit Board To The Battery Holder

    DIY 13kW 48V Offgrid Solar System: How to build it from scratch!

    It is impossible to run a solar-powered light directly from the solar panels. So, it would help if you linked the circuit to the battery. The battery will obtain energy from the solar panel via a charge controller, and this energy will be carried to the light through a circuit board.

    Be sure that you understand the output and input voltage. You have to consider the length and thickness of the cable and the inverter. This will depend on the type of connection.

    Luckily, this process is uncomplicated, and you can accomplish it in a few minutes. The task is similar to linking electrical lights on the light holders.
