Photovoltaic systems

All our complete systems are assembled according to the plug and play principle. The installation is therefore simple, uncomplicated and can be done without special tools.

Photovoltaics with storage—modern solar systems for homes and businesses

Solar island systems and numerous products for self-sufficient power supply:

Discover solar modules, solar systems, storage systems, batteries, and much more—all from a single source!

Stand-alone photovoltaic system

Photovoltaic Off-Grid Systems

What is a Solar Off-Grid System?

Off-grid systems are autonomous and independent systems for power supply. They operate without a connection to a public power grid and can be used as both permanently installed and mobile solutions. They are particularly useful in areas where there is no access to a national power grid. Examples include livestock fencing, toll control points in remote regions, or parking ticket machines.

Advantages of Off-Grid Operation

The term "off-grid operation" refers to a power supply system that works independently of a public power grid and generates and utilizes its own electricity.

Although there is a dense and reliable power grid in most European countries, off-grid systems are increasingly being used for technical devices with low power consumption. The use of photovoltaic off-grid systems allows for sustainable and independent power supply. They are the ideal solution for use in remote areas or for specific applications that do not require a continuous power supply.

Supply of AC mains voltage

Supply of Grid-Powered Alternating Current

Efficient Power Supply for High Demands Using Photovoltaics and Off-Grid Systems

Photovoltaic off-grid systems are also an efficient solution for applications with high power requirements, such as large events, remote gas stations, or small settlements. They are even utilized by fire departments and the military.

To ensure a constant frequency of 50 or 60 Hertz for devices that rely on grid-powered alternating current, off-grid systems require the following components:

  • DC Sources: Solar panels and batteries provide the necessary energy.
  • Generator Speed Control: Ensures stable performance.
  • Inverters: Convert direct current (DC) into alternating current (AC or grid power).

Advantages Over Diesel Generators

In high power consumption scenarios, gasoline or diesel engines coupled with generators are often used to generate the standard grid voltage. However, diesel generators and installed diesel power plants come with several disadvantages:

  • Limited Lifespan: Engine overhauls are necessary after approximately two years.
  • Low Efficiency: They demonstrate lower efficiency compared to coal power plants, especially at high loads.
  • Environmental Impact: Diesel generators produce harmful emissions, leading to air pollution and health risks.

Supply of AC mains voltage

Efficient power supply for high demands using photovoltaics and solar island systems

Photovoltaic island systems are also an efficient solution for applications with high power requirements, such as large events, remote gas stations, or small settlements. They are even used by the fire department and the armed forces.

To ensure a constant frequency of 50 or 60 hertz for devices that rely on mains AC voltage, stand-alone systems with the following components are required: 

  • DC sources: Solar modules and batteries supply the required energy.
  • Speed control of generators: Ensures stable performance.
  • Inverters: Convert direct current into alternating current to provide mains alternating voltage.

Advantages over diesel generators

When power consumption is high, gasoline or diesel engines with coupled generators are often used to generate the standard mains voltage. However, these diesel generators and permanently installed diesel power plants have a number of disadvantages:

  • Limited service life: Engine overhaul required after approximately two years.
  • Low efficiency: Particularly at high capacity utilization, they have a lower efficiency than coal-fired power plants.
  • Environmental impact: Diesel generators produce harmful emissions that cause air pollution and health risks.

Power storage and hybrid systems

Offgridtec Monteur der auf einem Dach arbeitet und dabei lächelt

Energy Storage and Hybrid Systems

To bridge periods of low output, batteries are a good solution. For stable operation, hybrid systems that utilize biogas or are powered by internal combustion engines can also be considered.

For devices connected to a solar system, a voltage converter from 12V to 230V is often required. To optimally store the generated electricity, the use of a specialized solar battery is recommended.

Why photovoltaics with storage is the best choice

Photovoltaic modules convert sunlight into usable electricity - but only with a storage system does your system become truly efficient. You can then use the electricity when you need it—even at night or when it's cloudy. Whether you opt for a grid-connected solution with feed-in or a self-sufficient stand-alone system: Offgridtec offers you complete flexibility.

Who is a solar system with storage suitable for? 

Private households: 

  • Reduction in electricity costs by up to 80 % 
  • Backup solutions in the event of a power failure 
  • Future-proof thanks to e-mobility & heat pumps

Trade & Industry: 

  • Cushioning load peaks 
  • Take advantage of subsidies 
  • Make energy costs calculable in the long term

Frequently asked questions about PV systems with storage

How much does a photovoltaic system with storage cost?

Prices vary depending on output and storage size. Offgridtec offers solutions in different price ranges.

How long does a storage unit last?

Our lithium storage systems have a service life of up to 15 years or 6,000 charging cycles.

Can I retrofit an existing system?

Yes! Many of our systems are modular and can be easily expanded.
