Definition:In a parallel connection, the voltage is the same at each resistor. The current is inversely proportional to the resistance values (i.e. the smaller the resistance, the greater the current that flows through it).

Definition:alternating currentType of voltage present in the alternating current of the power grid. Alternating current is electrical power in which the direction of flow reverses regularly (in 50 Hz the direction changes 100 times per second). Additionally, the voltage itself is not constant, but fluctuates periodically. The advantage of alternati [..]

Definition:rechargeable battery or solar batteryAccumulators or solar batteries are used for storing solar power in stand-alone systems for decoupling power generation and power consumption times. This way, solar power can be available at night, for example.

Definition:The unit for the electric current.

Explanation:The angle of inclination at which the solar modules are installed is important in terms of yield. The seasonal path of the sun means that the angle of inclination is flatter in the summer and steeper in the winter. Based on the annual average, the optimum angle of inclination for our parts of the world is approx. 30° – it increases acco [..]

Explanation:The Azimuth angle describes the deviation from the southern direction (southern hemisphere: northern direction). A solar power system produces the highest power yield at an Azimuth angle of 0 degrees, but even in a 45 degree Azimuth angle the energy yield of modules with a 30-degree inclination still reaches about 95 percent of the maxi [..]

Explanation:Photovoltaic modules are increasingly being used as integrated structural elements in façades and roofs. In the case of roofs, these elements replace the conventional roof covering (in-roof installation), while in the case of façades, they replace glass, natural stone or metal cladding. In visual terms, the integration of photovoltaics [..]

Definition:Carbon dioxide (CO2), the colorless and odorless gas, is a natural air component. It is produced during cellular respiration and is used by plants during photosynthesis. It is, however, also created in huge quantities by the burning of fossil energy sources. Due to its excessive accumulation in the atmosphere, it has a greenhouse effect [..]

Explanation:Central inverters are particularly suitable for building up photovoltaic systems with a homogeneous structure (modules of the same type with an identical alignment and inclination). They are used for installations from 100 kW upwards and, in most cases, are designed for outdoor installation.

Explanation:The amount of carbon dioxide (CO2) saved as a result of using a solar installation depends on the fuel that it replaces (gas, heating oil, coal) and the conventional energy that is used (electricity, district heating), and is proportional to the amount of fuel and energy saved. The amount of CO2 emissions avoided is obtained by multiply [..]
