Solar & Wind - Systems for alternative energies
Solar and wind energy are among the environmentally friendly energy resources, as the electricity is produced without fossil fuels and the process therefore has no negative impact on the quality of the atmosphere and the air in the breath. However, there are other consequences, such as the use of agricultural land for solar installations, possible noise pollution for residents and disturbance of habitats of animals in the vicinity of wind turbines. On the other hand, there are positive long-term effects. In addition, the technologies in the field of alternative energies have been considerably more efficient in recent years and the amount of hazardous chemical elements used has been significantly reduced.
According to the Energy Conservation Rate, energy cannot be "generated" or "destroyed", but can only be converted from one form to another. Losses – for example, as unwanted heat radiation – occur at all times, which are described with the efficiency of conversion technologies.
Solar energy uses the solar radiation that hits the earth and converts it into other forms of energy using suitable technical means.
Indirectly, wind energy is also a consequence of solar radiation, because different temperature conditions (due to solar radiation) result in different air pressure conditions, which are compensated by the redistribution of the air quantity in the form of wind.
In the field of non-industrial use, many interesting solutions have become established in the field of solar and wind.
What solar and wind systems are available at Conrad?
Solar small systems, usually as a set with all mounting and installation materials. Some of these systems are equipped with inverters, so that a 230-volt supply is possible. In this category, solar ventilation systems are offered, in which the converted electrical energy is used to drive fans. Target groups for these systems are, for example, campers, caravan users and sailors.
Solar fountains include all solar powered pumps for water delivery. Criteria for use are the available capacities (3,000 liters per hour), the delivery height up to 3 meters and the performance of the solar module. This subcategory also includes pond aerators and floating units.
Solar chargers as a mobile solution for charging batteries with different voltages for radios, smartphones or laptops via USB. Some solar chargers can be mounted on standard backpack sizes.
Solar lamps comprise various designs of light sources that work without power supply from the low-voltage power supply. These include decorative lights, light nets or curtains. The devices in this category are suitable for use in alarm and warning systems, among other things. Many models have a buffer accumulator that helps to bridge light-poor times. Conrad offers the "sun'connec" solar lighting system from the Chinese company Lutec as a system with all components.
Thermal solar systems are complete sets for environmentally friendly and free hot water supply based on solar energy. The components can be easily integrated into an existing heating system. The investment is worthwhile for subsequent installation in the old building and for planning in the new building. The Federal Office for Economic Affairs and Export Control also provides funding for private individuals and companies for this purpose.
Wind generators with power ratings from 100 to 600 watts. Areas of application are sailing boats, island systems, charging stations, holiday homes, WLAN access points, measurement and monitoring stations, traffic control or emergency call systems as well as development aid projects. Some wind generators are suitable for stand-alone systems or in combination with solar modules.
Modern wind turbines guarantee maximum energy yield even at low wind speeds. They are low-noise during operation and show little vibrations.
Special ball bearings on the rotating parts and coated individual parts enable a long service life and low maintenance. Special UV paint protects against embrittlement.
Solar modules: Off-grid systems are fixed or mobile systems. They are used where it is not possible or not economical to connect to the mains. Their operation is called island operation.
Solar systems: These are complete systems – from the absorption of solar energy in the solar module to the illuminant with connection material and buffer batteries.
Solar technology accessories ensure the installation and functionality of the solar systems. These include home energy storage as large buffer battery systems, various connectors and cables, installation accessories such as sockets, bushings, distribution blocks, brackets, inverters with accessories as well as thematically fitting specialist books.
FAQ – Frequently asked questions about solar and wind energy
Who uses solar and wind systems?
Architects, planning offices, in-house installation engineers, electricians, electrical installers, as well as private persons can install solar and wind systems, insofar as this permits the relevant regulations of the electrical trade.
What safety and operating instructions must be observed?
- In solar systems, which are used in environments with water (e.g. pond pumps), the utmost care is required. Before using the products, observe all manufacturer's safety and usage instructions.
- To clean solar modules, first remove dust and dirt on the surface with a soft brush. The surface of the solar module is wiped with a damp cloth to remove remaining dirt and dust. Guano and other attachments should be removed from the solar module surface as soon as possible to prevent performance degradation.
- Avoid contact of the actual solar modules with water.
- Sharp objects must not come into contact with solar modules.
- Solar modules must not be dismantled and repair attempts must not be attempted.
- Exposed electrical cables on the battery side must not be touched.
- Do not expose solar lights to extreme heat or open flames.
- Never remove the rating plates.
- Old electronic devices must be disposed of at public collection points and must not be disposed of in the household waste.
How can defective solar and wind technology be identified?
- Failure of the operating electrical system
- Heavy starting of the rotors due to wear or corrosion of the Rotating parts
- Low light yield. Please note: The light duration and intensity depends on the duration and intensity of the solar radiation. For buffered solar lamps, the rechargeable batteries must be replaced on average every two years.
