Solar modules & solar panels for mobile & stationary applications

Are you concerned about your electricity costs? Invest in a photovoltaic system now and become independent of your electricity provider! At Offgridtec, you will find a wide selection of solar cells, from monocrystalline PV cells to polycrystalline solar cells with batteries—we have everything you need for various applications 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 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 less dependent on 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 look 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, causing them to move. Inside the cell, an interaction takes place between the incident sunlight and the doped semiconductor of the solar cell. This converts sunlight into electrical energy.

Solar cells at a glance

We offer a wide selection of solar cells. 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). The use of thin silicon layers on the back of the silicon solar cell improves both passivation and electrical conductivity, thereby increasing the efficiency of the cell and the amount of electricity generated.

Perovskite solar cell

Perovskite solar cells are characterized by remarkable light absorption and excellent electrical conductivity. They are both inexpensive and easy to manufacture and process. However, they do not yet operate consistently enough to be used on a large scale.

Mini solar cell

Mini solar cells are particularly useful if you have limited space available, such as on a balcony. They are quick and easy to set up and generate enough electricity to reduce your electricity costs. This not only saves you money in the long term, but also helps the environment.

FAQ

1. What is a solar cell?
   A solar cell is an electrical component that uses sunlight to generate electricity. This is done by directly converting 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, 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 in the cell are excited and begin to move. Inside the cell, the incident sunlight interacts with the doped semiconductor and causes a reaction.
   
4. Which solar modules are suitable for a balcony power plant?
   Compact photovoltaic modules with an output of 300-400 W are usually used for balcony power plants. They are easy to connect and are ideal for supplying your own household with electricity.
   
5. Can I also use solar modules on the go?
   Yes, there are foldable solar panels and solar suitcases that are particularly suitable for camping, motorhomes, or boats. These mobile PV generators supply electricity 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 you from rising electricity prices. They also last a long time. A modern solar module is expected to reliably generate solar energy for more than 25 years. The biggest disadvantage is the high initial investment. In the long term, however, the costs pay off and make you less dependent on your electricity provider.
   
7. Do solar cells also work when the sky is cloudy?
   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 generate; the intensity of the light is irrelevant.
