How To Make Solar Panels: Crucial Things To Consider

Constructing an entire system yourself will take a lot of research and planning, consisting of sourcing the ideal materials and getting the proper permitting from your town.

It makes the most sense if you wish to develop a panel for a small project like as backup power for a recreational vehicle. We do not recommend developing your own solar panel system for use on your house, there are a lot of mistakes that can happen and lead to hazardous panels.

Available Types of Solar Panels

Before answering the question of how to make solar panels, we’ll be explaining and discussing the types of solar panels and how they are produced first. A solar PV module consists of solar batteries, glass, EVA, back-sheet and frame.

There are 3 kinds of solar panels available on the marketplace:

  • monocrystalline solar panels
  • polycrystalline photovoltaic panels
  • thin film solar panels

Hence, at cell structure level, there are various types of material for production, such as mono silicon, polysilicon or amorphous silicon (AnSi). The very first 2 type of cells have a somewhat similar manufacturing procedure.

How Are Solar Panels Produced?

Below are 6 main steps of producing a crystalline photovoltaic panel.

The Sand Step

All of it starts with the raw product, which in our case is sand. Many photovoltaic panels are made of silicon, which is the primary part in natural beach sand.

Silicon is generously offered, making it the 2nd most available element in the world. Converting sand into high grade silicon comes at a high expense and is an energy extensive procedure. High-purity silicon is produced from quartz sand in an arc heater at very heats.

The Ingots Step

The silicon is collected, usually in the form of solid rocks. Hundreds of these rocks are being melted together at really high temperatures in order to form ingots in the shape of a cylinder. To reach the wanted shape, a steel, cylindrical heater is utilized.

In the process of melting, attention is offered so that all atoms are completely lined up in the desired structure and orientation. Boron is contributed to the process, which will give the silicone favorable electrical polarity.

Mono crystalline cells are manufactured from a single crystal of silicon. Mono Silicon has higher efficiency in converting solar energy into electrical power, therefore the cost of monocrystalline panels is higher.

Polysilicon cells are made from melting a number of silicon crystals together. You can recognize them by the shattered glass appearance provided by the different silicon crystals. After the ingot has cooled down, grinding and polishing are being performed, leaving the ingot with flat sides.

The Wafers Step

Wafers represent the next step in the production procedure. The silicon ingot is sliced into thin disks, also called wafers. A wire saw is used for precision cutting. The thinness of the wafer is similar to that of a piece of paper. Because pure silicon is shiny, it can reflect the sunlight. To decrease the amount of sunshine lost, an anti-reflective covering is placed on the silicon wafer.

The Solar Cells Step

The following procedures will convert a wafer into a solar cell efficient in converting solar power into electrical energy. Each of the wafers is being treated and metal conductors are added on each surface area. The conductors provide the wafer a grid-like matrix on the surface. This will make sure the conversion of solar power into electrical power. The finishing will help with the absorption of sunlight, rather than showing it.

In an oven-like chamber, phosphorous is being diffused in a thin layer over the surface area of the wafers. This will charge the surface area with an unfavorable electrical orientation. The mix of boron and phosphorous will provide the positive – unfavorable junction, which is important for the proper function of the PV cell.

From Solar Cell to Solar Panel Step

The solar cells are soldered together, utilizing metal connectors to connect the cells. Solar panels are made of solar batteries incorporated together in a matrix-like structure.

The current basic offering in the market are:

  • 48 cell panels – suitable for small domestic roofing systems.
  • 60-cell panels – this is the standard size.
  • 72-cell panels -used for massive setups.

The most common sized system in terms of kWh for UK houses is the 4kWh solar system.

After the cells are put together, a thin layer (about 6-7 mm) of glass is included on the front side, facing the sun. This will prevent water, soil, and other materials from getting in the panel from the back.

Everything comes together when the frame is assembled. The frame will also supply protection versus effect and weather condition. Making use of a frame will also enable the mounting of the panel in a variety of methods, for instance with installing clamps.

EVA (ethylene vinyl acetate) is the glue that binds everything together. It is very crucial that the quality of the encapsulant is high so it does not harm the cells under harsh weather.

The Final Step: Testing the Modules

Once the module is ready, testing is carried out to ensure the cells carry out as anticipated. STC (Basic Test Conditions) are used as a referral point. The panel is put in a flash tester at the manufacturing center. The tester will deliver the equivalent of 1000W/m2 irradiance, 25 ° C cell temperature level and an air mass of 1.5 g.

Electrical specifications are documented and you can find these outcomes on the technical spec sheet of every panel. The rankings will reveal the power output, efficiency, voltage, present, effect and temperature tolerance.

Apart from STC, every maker utilizes NOCT (nominal operating cell temperature level). The specifications utilized are more near to ‘reality’ scenario: open-circuit module operation temperature at 800W/m2 irradiance, 20 ° C ambient temperature level, 1m/s wind speed. Again, the rankings of NOCT can be found on the technical spec sheet.

How To Make Solar Panels: Is It Possible to Do It Yourself?

Yes, it is possible to build your own solar system – and even the solar panels – from scratch. It can be dangerous given that faulty workmanship will lead to breaks and system failure.

Solar panels are made by soldering together solar cells into strings, signing up with these strings together, and connecting them to a junction box. As soon as joined together, the parts must be sealed so that the active parts of the solar panel are water resistant.

It is not technically tough to make a single solar panel, it is generally soldering wires and solar batteries.

The greatest issue is finding quality product to build the panels. Generally, the products are acquired in an ad hoc fashion from several suppliers, so quality is tough to track. Building photovoltaic panels from non-quality devices can cause damaged panels or threat of fire from defective craftsmanship.

If you wish to develop your own panels, we advise constructing them on a smaller scale, for things like running electrical energy to your shed, instead of a whole home. Small tasks will keep power demands low, that makes DIY installation manageable and less likely to break.

For someone with little to no experience in solar devices, it can be dangerous to construct and install a system large enough to power your house. You can discover more details, the exact detailed guide on how to make solar panels on these excellent resources:, and

Learn How to Build Home Energy System





How To Make Solar Panels: Step by Step Process

Keep in mind, before sourcing your equipment, it is essential to remember that solar cells offered on websites are generally seconds that didn’t make it past quality control. They can be broken, blemished, or otherwise harmed, which is definitely not perfect. You can follow the detailed procedure below.

Design and Identify Size of Your System

Design and determine the size of your system based upon your energy requires. To determine the number of photovoltaic panels you will need, you require to understand how much energy you prepare to utilize on average monthly, and just how much sun direct exposure you can anticipate throughout the year. Once you understand that, you can choose which brand and model of photovoltaic panel will make good sense for you.

If you are developing panels for a little task or home appliance, you will need less panels Merely determine the kWh the home appliance will need, then find out the number of panels to build from there.

Buy Components for the Panels

You will need to buy the components that comprise a solar panel. This consists of:

  • Solar Battery. These elements are what converts the sun’s energy into electricity, each solar panel consists of about 36 solar cells.
  • Pre-Soldered Electrical Wiring. Buying pre-soldered tabbing wire will cut some steps out of the process, but you will still require a soldering iron to solder the wiring to the back of the solar batteries and string the wire correctly to link the solar batteries.
  • Non-Conductive Material (wood, glass, or plastic). For do it yourself solar panels, wood generally works best as support due to the fact that it is simple to drill holes for the wiring. When you have your solar cells wired together, you can glue these to the wood support and then connect all of the wires and solder each solar battery together. After wiring, you then link these wires to a charge controller, which controls the volts of energy. Wood can likewise be used to construct a box to secure the solar cells and then to lay the plexiglass on top for wetness security.
  • Plexiglass, You’ll need this element to seal the solar panel. As soon as your solar batteries are wired and glued to the wood backing, you require to seal them with plexiglass for defense from heat, debris, and moisture.

Purchase Extra Solar Devices Like Inverters and Racking

If you do not trust yourself to build photovoltaic panels from scratch, you can buy a photovoltaic panel set which will include more specific guidelines (and typically racking) to help protect your panels Acquiring a solar set might actually be more useful because it will consist of racking already.

Racking is tricky, you will need to identify which racking devices works for your specific roofing system type or ground install. There is practically a frustrating amount of alternatives of securing and installing equipment readily available if you look at wholesale supplier websites.

Set Up the Racking for Your Photovoltaic Panels

When acquiring racking, choosing which alternative to buy depends upon where your panels will go. Will they be ground installed, or on your RV? This will identify the kind of racking you require to buy. When you select your racking, you need to map out where you will drill the holes to secure the racking to your structure.

Link the Photovoltaic Panels to the Racking Equipment

To protect photovoltaic panels to the racking equipment, you will need clamps, or adapters, that are made for the racking you pick. Purchasing them together and from the same supplier is an excellent way to make certain they are developed for each other. Solar panel kits normally come with racking however if you buy everything individually, make certain you do the research to construct a totally operating solar energy system.

Set Up the Correct Solar Inverter

Installing a solar inverter takes knowledge since it will need to be connected the electrical grid. For this, we recommend using the help from a professional installer, as they will do this safely and efficiently with the right permits.

How To Make Solar Panels: The Skills You Need

Solar panels are relatively easy enough to build, but for them to remain practical for an extended period of time, they need to be constructed with severe accuracy. Solar panels require to be able to preserve their integrity in severe weather and from consistent exposure to heat and sunlight.

Safety is the greatest worry about homemade solar panels. Wetness can get in and ruin them and there is the capacity for poorly developed panels to catch fire from the sun’s heat. Mastering the soldering and electrical circuitry is a difficulty that usually takes the understanding of an experienced electrical contractor or engineer.

Constructing a system requires a desire to research study, make mistakes, and gain experience in electrical circuitry abilities and soldering methods. So if you are a skilled engineer or electrical contractor, this can be a bit easier to master but it is certainly not a fast weekend’s worth of DIY-ing.

How To Make Solar Panels: The Kits You Need

While building solar panels from scratch and after that retrofitting a whole solar system is possible, many people generally want to build a solar system from pre-made devices and after that set up the system.

The primary benefit of purchasing a packaged solar package, like one from Grape Solar versus purchasing all of the material independently, is that the devices within the package is ensured to work together. That is not necessarily the case if you buy each item ad hoc. For example, certain solar panels and inverters can only deal with each other within defined electrical specs.

Unless you’re identified to develop a system from the ground up, a photovoltaic panel package is a much better alternative and will be more economical and confusing.

How To Make Solar Panels Yourself: The Pros and Cons

The majority of DIY jobs have their pros and cons, however since solar systems deliver electrical power to your house, having actually properly made panels is very essential. It is the difference between saving a few thousand dollars versus having solar panels that you know will be safe. As you can see, the cons considerably surpass the pros.

Pros and Cons of Developing Your Own Solar System


  • Strategies and directions are readily available online at little to no cost. Having the ability to follow the actions to constructing a panel is definitely possible, however it is a big task to handle.
  • Manufacturing your own photovoltaic panels for little off-grid tasks can be an excellent learning experience. If you have an engineering frame of mind and are curious about how solar panels work, this could be a fun obstacle for you.


  • Homemade photovoltaic panels set up improperly can cause fires due to intense heat accumulation on hot, bright days.
  • If you choose to purchase secondhand from sites like eBay, you’re most likely acquiring factory seconds, rejected, or harmed solar cells. Buying any of those products is bound to result in system failure.
  • Homemade systems often violate electrical codes, this will lead to problems in permitting. It’s much easier to depend on a solar business to handle electrical codes.
  • Homemade panels are not eligible for rewards, like the federal tax credit, or refunds which assist reduce the expense of home solar systems.
  • Warranties on any parts will be invalidated, design guarantees are typically just covered if installed by a professional.
  • The quantity of cash you save may have a short service life. If your panels break, you will be on the hook for that expense. Not to mention, homemade panels will not last as long as professionally-built panels.

Why Professional Installation is Better Than DIY

The expense of a solar system installation can be frightening – however, there are many funding alternatives like solar loans, along with rewards for property owners that can considerably minimize the rate.

While solar system setup expenses are costly, installers have decades of hands-on experience– something no amount of research study or directions can duplicate.


At the end of 2020, the federal tax credit was extended, so you can get a tax credit of 26% on your solar system until 2023. To reiterate, you would not be qualified for this reward if you constructed and set up the panels yourself.

DIY solar panels and solar systems are possible but are best left for science tasks or small-scale use. Professional installations may not offer you the complete satisfaction of completing a job, however they can give you comfort.

Research and development in the solar energy industry is aiming at decreasing the expense of photovoltaic panels and increasing efficiency. The solar panel production market is becoming more competitive and is forecasted to become more popular than conventional sources of energy, such as fossil fuels.

If you are looking for a step-by-step course that teaches you how to lower your energy bills and become more energy independent and self-sufficient by building your own power at home with professional quality solar panels then this is the right system that you can count on.
