How to Build a Solar Panel in 9 Easy Steps (with Pictures)

If you can make renewable energy successful, there are numerous considerable reasons to just take benefit of it. Photo voltaic energy is environmentally welcoming and can support keep your monthly electrical bills down.

The prospect of creating a photo voltaic panel can seem complicated and overwhelming. Connecting an entire property to solar electricity is in fact a lot more trouble than the average DIYer could safely and affordably manage. But for little assignments this kind of as powering outdoor sheds or supplying electric power to an RV, straightforward factors and fundamental steps are all you want to consider benefit of photo voltaic panels.

To support you get commenced on your solar power project, we’ll wander you through how to create a solar panel in nine easy steps.

Preparation

Prior to creating your solar panel, you need to have to acquire solar cells, which can be the most difficult portion of preparation. Photo voltaic cells are made throughout the globe, but some of the most trustworthy are American or Japanese-produced.

Photo voltaic cells are obtainable in monocrystalline and polycrystalline types, as well as a newer engineering known as slim-movie. Each has its tradeoffs in efficiency and cost, with monocrystalline getting both the most expensive and the most power-effective.

The variety of cells you purchase will rely on the volume of energy you desire to produce. Every single model will have specs to reveal the predicted strength output. It is critical to always shop close to for pricing and assures to get the greatest value. No matter which technological innovation you pick, usually acquire further solar cells for your venture need to you damage any in the course of the build.

How to Build a Solar Panel (9 Steps)

1. Build a Backing Board

Your solar panels require to be secured in a body to stop hurt and movement whilst they are out in the elements.

To commence the frame, you will require to lower a backing board manufactured of a non-conductive materials these kinds of as glass, plywood, or plastic. Wood is usually the simplest to use when chopping holes to thread the wiring.

Minimize your backing board to match the amount of cells you want to use. Go away an added 1–2 inches all around the edge to leave space for wires.


2. Attach Tabbing Wire to the Front of the Solar Cells

Each and every photo voltaic mobile has two big lines operating parallel to every single other across it on the facet that faces the sunlight. This is the damaging aspect. You want to implement tabbing wire to the two lines on this aspect to link each and every cell in the system.

Evaluate a operate of tabbing wire 2 times as prolonged as the cell’s width. For example, if the two lines running parallel are four inches extended, you need to minimize two 8-inch items of tabbing wire.

Operate a flux pen down the duration of equally solar mobile lines to cover them with flux. Undertaking so cleans the surfaces and stops beading and oxidation, permitting for a stronger, far more sturdy bond.

Lay a tabbing wire strip over the initial line on the mobile, and have the other 50 percent operate off the edge of the cell. Solder the tabbing wire to the mobile. Repeat this on the other line.

You now have a solar cell with two parts of tabbing wire sticking out of one facet like prongs.

Repeat this process on all of your solar cells so you can connect them in a collection.

  • Note: To save time, you can buy cells with pre-soldered tabbing. It’s more expensive, but it is more accurate, quicker to use, and uses less solder.

3. Connect the Cells

To hook up the cells, the overhanging tabbing wire on the initial cell will slide below the cell following to it. There are three connection factors for every of the two wires on the again (optimistic side) of the mobile.

Solder the tabbing wire from the initial cells to these factors, utilizing a flux pen to prep every position. For instance, if you have a four-inch broad panel and an eight-inch lengthy piece of tabbing wire, four inches of wire will be soldered to the best line on the unfavorable facet of one mobile, and the other four inches will be soldered to the underside (positive side) of the mobile up coming to it.

You need to now have two cells linked in a louvered trend. Repeat this process with every successive cell until you have completed the line.


4. Finish the First Row

On the initial cell in the line, solder two one-inch lengths of tabbing wire to the adverse aspect so they prolong previous the edge, achieving toward the edge of the backing board.

Cut a piece of bus wire to span the distance among the two tabs. For illustration, if the two lines have been five inches aside, cut a five-inch piece of wire to connect them. Solder the bus wire to the two parts of tabbing wire.


5. Glue the First Row

When you complete the first row of cells, you can affix it on the backing board. Put a drop of glue or silicone caulk in the center of every mobile on the back and put it in area on the board.


6. Complete and Connect Additional Rows

If you have several cells, you are going to probably want to stack a pair of rows so you really do not have one prolonged line of cells. To link one particular row to the subsequent, you will require to connect two one-inch parts of tabbing wire to the ends of one row and the starting of the subsequent row (equivalent to step four). You then connect all four bits of tabbing wire with a bus wire.

The rows ought to snake back again and forth. For instance, if you have rows of 5 cells, the fifth cell of the initial row will link with the initial mobile of the next row, which operates in the opposite course on the board. At the stop of the last row, use a piece of bus wire to hook up the two lines of the final cell.

Glue the extra rows in area on the backing board.


7. Build the Box

The solar cells need to be encased behind plexiglass to stop damage and wear. You can do this in various approaches. In general, you want brief one-inch partitions and a piece of plexiglass to go over it and defend the cells.

Ahead of adhering the glass to seal the cells, you require to end wiring the panel.


8. Add a Junction Box

Connect a junction box to the back again of the board with silicone. You can do this with a chase nipple, drilling a ¾-inch hole to in shape it.

9. Finish Wiring the Panel

Move two lower gauge wires by way of the junction box and backing board so the finishes meet the bus wires of the last solar cells. Solder your black wire to the negative bus wire on the first mobile. Solder your crimson wire to the optimistic bus wire on the final mobile.

You can then run wires from your junction box to the demand controller and on to the battery. Right after screening your photo voltaic set up in the sunlight with a multimeter, you can seal the plexiglass over the case and total the panel.

Conclusion

Creating a photo voltaic panel is an outstanding opportunity to find out a new and useful talent that could potentially conserve you time and money. Always be careful when functioning with electrical and soldering tools, producing confident to put on protecting equipment and testing the panel ahead of completing the encasement.

As you can see, creating a photo voltaic panel from scratch is a uncomplicated and gratifying venture. Stick to these nine straightforward steps to start off getting benefit of photo voltaic vitality today!
