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 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.
Advantages over Diesel Generators
When power consumption is high, gasoline or diesel engines with coupled generators are often used to generate standard grid voltage. However, diesel generators and permanently installed diesel power plants have several disadvantages:
- Limited lifespan:
Engine overhaul required after approximately two years - Low efficiency:
Especially under high load, their efficiency is worse than that of coal-fired power plants - Environmental impact:
Diesel generators produce harmful emissions that cause air pollution and health risks
Renewable Energies
Economics and Flexibility
Renewable energies are becoming increasingly economical due to decreasing costs of solar technology and rising fuel prices. The choice of system depends on the specific application.
Off-grid solar systems are suitable for:
- Motorhomes & Boats: Independent power supply for travel.
- Garden Houses: Standalone energy supply for lighting and appliances.
- Home Gardens: Powering irrigation systems and workshops.
- Off-Grid Homesteads: Power supply away from public grids.
- Construction Sites: Energy supply for construction containers.
In other situations, the use of wind energy, hydropower, or wave energy may also be beneficial. Additionally, factors such as power demand play a crucial role, as a photovoltaic off-grid system in the megawatt range can be significantly more expensive than a wind turbine.
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.
