Solar modules & solar panels for mobile & stationary applications

Are you concerned about your electricity costs? Invest in a photovoltaic system now and make yourself independent of your electricity provider! At Offgridtec you will find a wide range of solar cells, from monocrystalline PV cells to polycrystalline solar cells with battery - we have everything you want to generate your own green electricity.

Solar modules as generators of photovoltaics

Solar modules—also known as solar panels or photovoltaic modules—act as generators in every PV system. They convert sunlight directly into electrical energy and are therefore at the heart of every photovoltaic solution.

Whether as a foldable PV module, solar suitcase, or stationary system, each panel is a compact power generator that makes you more independent from the grid. This allows you to generate your own energy where you need it—in your home, RV, garden, or off-grid projects.

Solar panel – the common name for solar modules

Customers often search for a solar panel, but sometimes they also mean a solar module. Both terms refer to the same technology: photovoltaic panels that convert sunlight into electricity. In our shop, you will find solar panels in various designs – from foldable solar panels for camping and motorhomes to powerful panels for balcony power plants or stationary systems. This means you can cover every application, from mobile use to large-scale projects.

How solar cells work

The way solar cells work is very simple: when sunlight hits the solar cell, the electrons in the cell are excited so that they move. Inside the cell, an interaction takes place between the incident sunlight and the doped semiconductor of the solar cell. This is how sunlight is converted into electrical energy.

Solar cells at a glance

You will find a wide range of solar cells in our shop. These include silicon solar cells, perovskite solar cells and even mini solar cells.

Silicon solar cell

Silicon is the most widely used technology for photovoltaics (PV). By using thin layers of silicon on the back of the silicon solar cell, both passivation and electrical conductivity are improved, increasing cell efficiency and power generation.

Perovskite solar cell

Perovskite solar cells are characterised by remarkable absorption of light and excellent current conduction. They are both inexpensive and easy to manufacture and process. However, they do not yet work consistently enough to be used on a large scale.

Mini solar cell

Mini solar cells are especially helpful if you have limited space, such as on the balcony. They can be set up quickly and easily and generate enough electricity to relieve your electricity costs. This way you can not only save money in the long run, but also do something for the environment.

FAQ

1. What is a solar cell?
   A solar cell is an electrical component that uses sunlight to generate electricity. This happens through the direct conversion of sunlight into electrical energy.
   
2. What is the difference between a solar module and a solar panel?
   Both terms are used synonymously. “Solar module” is the technical term, while “solar panel” is the colloquial term for the same PV technology.
   
3. How does a solar cell work?
   When sunlight hits the solar cell, the electrons inside the cell are excited and start moving. Inside the cell, the incoming sunlight interacts with the doped semiconductor, triggering a reaction.
   
4. Which solar modules are suitable for a balcony power plant?
   Compact photovoltaic modules with 300–400 W output are usually used for balcony power plants. They are easy to connect and ideal for household self-consumption.
   
5. Can I also use solar modules in mobile applications?
   Yes, there are foldable solar panels and solar suitcases that are particularly suitable for camping, motorhomes or boats. These mobile PV generators supply power independently of the grid.
   
6. What are the advantages and disadvantages of solar cells?
   Solar cells are a great way to reduce your electricity costs and protect yourself from rising energy prices. They also have a long lifespan. A modern solar module is expected to reliably generate solar energy for more than 25 years. The biggest disadvantage is the high initial investment. However, in the long run, the costs pay off and make you more independent from your electricity provider.
   
7. Do solar cells work even under cloudy skies?
   Solar modules use not only direct sunlight but also diffuse radiation that passes through clouds or fog. The brighter it is, the more power the modules deliver; the intensity of the light itself is not decisive.
