Power from the sun

Free solar energy for generating power using photovoltaics As renewable energy systems have become more widespread, consumers and end users have become increasingly keen to generate their own electricity. Today, an efficient photovoltaic system offers the opportunity to make profitable use of free solar energy. By installing photovoltaic modules, users demonstrate their responsible attitude towards the environment, and make an active contribution towards protecting the climate by reducing CO emissions.
With energy costs constantly rising, a photovoltaic system helps users save money and reduces their dependence on energy suppliers. The power they generate can be used for their own needs or exported to the public grid. Thanks to statutory remuneration and savings resulting from on-site consumption, the investment pays for itself in just a few years. A photovoltaic system also increases the value of the On the following pages you will find comprehensive information on the Viessmann photovoltaic system and the perfectly matching components available. These include photovoltaic modules, inverters, assembly systems, power storage systems and heat pumps to help you consume more of your own power on site.
The high quality provided by the photovoltaic modules ensures economic efficiency and a long service life. Comprehensive services from planning and sizing through to delivery and servicing complete the photovoltaic offer provided by Viessmann's professional trade partners.

Saving energy and protecting the climate Viessmann is aware of its responsibilities towards the sustained protection of the environment. Our company philosophy and products have been designed with this duty in mind.
"Nothing is so good that it cannot be Efficient photovoltaic systems
Viessmann offers energy improved". This motto is also reflected in By installing a Viessmann photovoltaic efficient heating systems for oil, gas, solar, biomass, air our company principles. Viessmann can system, anyone can generate their own and geothermal heat. The rightfully claim to be the leader in quality and power.

of energy consumption in Germany. The rest is shared by freight, personal transport and power generation, each accounting for 20 percent. These values can also be applied approximately to other industrial countries. Ever-rising energy costs mean that the emphasis is on reducing the consumption of fossil fuels as quickly as possible.
Good reasons to choose a photovoltaic system from Viessmann A module surface area of 450 x 450 km Generating electrical power directly from solar would be sufficient to cover the power energy, known as photovoltaics, is an elegant demand of the entire world. Our sun not only and reliable option.

Electrical power is Germany is equivalent to approx. 80 times the generated directly in the photovoltaic module. country's total energy consumption. Around However, in solar thermal systems, the half of this reaches the Earth's surface as heat gained in the collectors is transferred direct insolation, the other half as diffused hydraulically via a heat transfer medium, so it can be used for DHW or central heating.

Feed-in remuneration and using generated
power on site
If you generate your own power, you can receive a guaranteed remuneration from your photovoltaic module with power supply utility over 20 years. This is black anodised frame and governed by the German Renewable Energy dark Tedlar film with an Sources Act (EEG), which states that energy output up to 275 Wp utilities are obliged to accept the power not consumed on site and absorb it into their grid.
There are currently two ways in which the solar power generated by a rooftop Polycrystalline photovoltaic photovoltaic system can be used: It can either module with 48 cells and be exported to the grid in its entirety, or it can an output of 200 Wp be partially or completely consumed on site.
In the past it was usually more financially attractive to export all solar power generated into the grid. Falling feed-in tariffs on the one hand and increasing electricity costs on the other, make the option of using your own Polycrystalline photovoltaic power on site more appealing. Electricity module with 60 cells and costs per kilowatt hour are generally far higher an output up to 265 Wp than the remuneration tariff for the same kilowatt hour of solar power that is exported into the grid.
For this reason, the number of house builders interested in this form of power generation is continuing to grow.

Vitovolt function explained
Basically, a mains-connected solar power system operates in three stages: 1. Harvesting energy
When light falls on the photovoltaic modules, electrons are released inside the solar cells. Positive and negative charge carriers collect at the respective electrical contacts, resulting in a DC current between the front and back of the cell. This photoelectric effect is created without mechanical or chemical reactions, and so is maintenance-free and not subject 2. Power conversion
DC power generated by the solar generator is then converted by the inverter (commonly known as a mains feed-in device) into AC power suitable for the grid (230 or 400 volt AC current at 50 Hz). Proven safety standards and Vitovolt
fully developed processors, as well as cutting Silicon solar cell
edge power electronics, ensure effective conversion of the solar power.
1 Negative electrode 2 N-doped silicon 3. On-site consumption
The falling remuneration rates for privately 4 P-doped silicon generated solar power and the rising cost 5 Positive electrode of electricity are motivation enough for developing an optimised energy concept for detached and two-family houses. In the meantime, using solar power in your own home – the more the better – has become much more attractive financially. Using a power storage system for solar power generated at home increases the rate of power consumption on site and reduces purchases from the grid still further.
