Do you remember when people said solar power was the future? Well, the future has been here for a long time. Plus, with electricity at record levels, now is the perfect time to switch to renewables and say goodbye to electricity, if not permanently, then in a relevant way. And we will teach you how to make a homemade solar panel.


Not only that. We’ll show you it’s much more economic than you imagine; much easier than expected; and much more profitable than you dreamed of. Like the Kinder Surprise, three surprises in one. In this case, change the egg to chocolate, for a photovoltaic solar panel.

How To Make A Homemade Solar Panel | materials

When choosing a solar panel, keep in mind that there are many types. Since sign Solar Thermal, at sign solar thermoelectric, through the photovoltaic energy panel, that’s what we’re going to build. Obviously, whatever its type, before learning how to make a homemade solar panel, we need materials.

home base solar panel

the photovoltaic energy panel is made of semiconductor materials that turn light into electricity, ready for consumption. In other words, depending on the panels you have, you can meet all your demand. Household appliances, home lighting, even electric car charging

Materials for a photovoltaic panel

  • One square meter non-conductive base – The Plastic It is the most suitable because it is light, resistant and can last for years without a problem. In addition, very easy to find in any specialty store, where they cut it on request. If you prefer the woodIt is also a good option, although it should be accompanied by painting to give it greater resistance, especially to bad weather.


  • Solar cells – Here you have two options: buy the new cell or search the factory remains or with a manufacturing defect, which you will get much more cheap. The second you find them on the Internet and the first, in any store. Of course, make sure they come without wax and you will avoid having to remove it later.
  • Plexiglass one square meter
  • Silicone and a blocking diode
  • Low power soldering iron (the one you should ask your neighbor or someone you know).

Price of a homemade solar panel

The photovoltaic solar panels They are the most in demand because they directly provide you with the electricity you need in your home every day. In addition, it is common to find them in the usual DIY stores (Leroy Merlin, Brico deposit…). To give you an idea, the price of a home solar panel economical and basic around 200 euros. From then on, whatever you want to spend.


The idea in doing it the artisanal way is that they are worth less 200 euros and, incidentally, have more quality than that low end. Of course, don’t plan to light up the neighborhood or a commercial space. The amount of electricity that this home solar panel will generate will give you for your regular home use.

So by adjusting the price on whatever we buy, an almost 100W panel, with 36 cells, will be around 30-35 euros. To that must be added the base, the glue, the plexiglass, the paint and the soldering iron (which you can ask your neighbor, if you do not want to spend 200 euros).

If you search well on the Internet or if you accept an offer, the price of a home solar panel can be around 60 euros. In other words, save 190 euros in each of them.

How to make a homemade solar panel step by step

And since we started to compare Kinder SurpriseLet’s say it’s one of your life-size surprises. In addition, the how to make a homemade solar panel step by step It is also not too complicated than a toy for children. Of course, it will be more laborious, but with a few advantages and a economy economic immense for you.

Step 1 – Take the base (remember to paint it if it is made of wood, even if we recommend plastic all the same) and put the cells solar on its surface. Use a ruler to keep it as tight as possible. Since you started doing it, do it right, right?


2nd step – Remember that you need to distribute the solar cells on both sides of the base. As easy as putting 15 on one side and 15 on the other. If at the time of placing them, one breaks, do not worry, it happens in the best families. The solar cells just looked at me and didn’t touch me, so that’s advised to have several spare parts.

Step 3 – Once aligned, it is necessary connect them, a step easier than it seems. You just need to join the positive shots of cell with negatives of the next. To make sure they don’t come apart, you need to spot weld it with your neighbor’s machine and very carefully. Remember they are very sensitive, it is therefore advisable to turn the panel over when soldering it.

Step 4 – Once all the soldiers have been, you must place the blocking diode. This mechanism will help the energy accumulated during the day not to be lost at night. Which company.

Step 5 – Moment plexiglass. It’s time to protect our household gadget. As easy as placing the plexiglass panel over the connected solar cells and securing it with multiple screws. The idea is protect it from the wind, rain, gel and others, therefore, it is recommended that the plexiglass panel protrudes a little on the sides.

Step 6 – Just take the cables to main outlet and now you have it, your own solar panel. You will be like a small branch of Iberdrola, in which you will manage your own electricity.

Step 7 – Think about what you are going to do with the money you save. A family trip, a trip without a family, a family trip, a family on a trip, a trip to find a family… Your money, your decision.

Advantages and disadvantages of installing a solar panel in your home

It is assumed that if you have embarked on the adventure of making a homemade solar panel, it is because it compensates you. However, it is worth revisiting the advantages and disadvantages of installing a solar panel in your home

Benefits of installing a solar panel in your home

We start to advantages of installing a solar panel in your home this, a priori, goes beyond the disadvantages.

  • Renewable – Obviously it seems complicated that the energy of the sun will run out, so we have renewable energies for millions of years. On the other hand, the sun sends 120,000 TW of solar radiation to the Earth, which is 20,000 times more energy than needed to power the whole world. There is a lot of solar energy for everyone.
  • Zero emissions – Not only is it renewable, but it is also ecological and environmentally friendly, producing no emissions in the environment.
  • Economic – Solar energy not only allows, in many cases, self-sufficiency. Now, with bidirectional meters, the remaining energy of a house can be returned to the electricity grid and benefit the user economically.
  • Minimal maintenance – The maintenance of solar panels is minimal. You don’t even need to clean them. To give us an idea, some have up to 20 years warranty.

  • Universal – The sun is an element that offers its attributes to the whole planet, so that everyone can enjoy them. Even in areas with a lot of rain or a few hours of sunshine, you can enjoy everything there is.
  • Quiet – Solar energy does not generate any noise, which other types of energy cannot tell
  • Community systems – Many apartments do not have a garden, terrace or space to install. For this reason, many communities have come together to create community solar gardens, fostering collaboration and neighborhood action.
  • Advances – Solar panel technology does not stop. Despite the slowdown in countries like Spain, researchers are still looking for ways to improve performance. In the short term, they hope to launch smaller solar panels which, in turn, are able to store three times more energy than current panels.

Disadvantages of installing a solar panel in your home

And yes, even if it’s hard to believe after reading the benefits, there are disadvantages of installing a solar panel in your home.

  • It is not fixed – Although the sun always rises, on rainy, cloudy or stormy days, solar panels do not work 100% efficiently and this is noticeable in some installations.
  • Expensive in two ways – Depending on where it is placed, installing home solar panels can be expensive. As well as storing energy to have plenty of it in case you need a cloudy day.
  • Space – At the moment, it is the big problem with solar panel installations, which take up a lot of space, which limits their use in large cities.
