Electric energy from solar energy is also called solar power. The Sun produces energy through nuclear fusion, which reaches the Earth in particles as electromagnetic radiation. Photovoltaic systems (PV) convert this energy into electricity.
Solar cells are responsible for this. When the sunlight strikes the solar cells, electrons are released from a semiconductor material, thus separating electrical charges. This creates electrical voltage that flows through an inverter generating alternating current.
Another form of heat production from solar energy is from solar thermal power plants (solar power plants).
- Solar power is generally available to everyone everywhere.
- Solar power is inexhaustible.
- Solar power is regenerative, passive, noiseless and emission-free.
- Solar power makes you independent of rising energy prices.
The most important components of the photovoltaic system are the solar cells, which are assembled into larger units in so-called solar modules. They are protected from contamination by glass and fixed on the roof by means of a mounting system.
In order to produce enough electricity, several solar modules are necessary. They generate direct current, which is then converted to alternating current via inverters. By connecting them to the house, the electricity can now be used - "fresh from the roof" - or fed into the general electricity grid.
Electricity that is not consumed immediately can either be fed into the general electricity grid or stored with batteries using a storage system. In this way, it is available in your own household at another time.
Control systems monitor the performance of the photovoltaic system, so that the current power production can be measured at any time.
The current solar modules are expected to last about 30 years. However, experts from the Fraunhofer Institute for Solar Energy Systems believe that their lifespan can be 40 years or more.
Grid-connected modules make it possible to upload solar power into the general electricity grid. The grid operator is obliged after a period of 20 years to remove surplus electricity from solar systems.
There are differences in the rates paid. Therefore, it is worthwhile comparing the offers of the individual electricity providers.
At the end of the 20 years, you can feed the unused electricity into the electricity grid at the exchange electricity price. Another possibility is the purchase of new modules. The old modules can be recycled in an environmentally friendly way.
The annual solar radiation in Austria averages 1,100 kWh per square meter in Vienna, Burgenland, Upper and Lower Austria. It can even reach 1,400 kWh south of the Alpine regions. Thus, even with smaller solar systems, sufficient electricity for a household can be produced.
In order to adapt your Energy3000 solar system to your location, solar radiation is calculated in advance. This will adjust the performance of your modules.
Energy3000 solar does not sell its products to end customers, but relies on selected specialist partners for sales. Local installation specialists create your photovoltaic concept according to your personal situation. Our specialist partners install the system professionally and put it into operation for you. You receive competent guidance and can always rely on these specialist partners for maintenance and service.
Energy3000 solar grants product warranty for up to 15 years on new photovoltaic modules. In addition, you benefit from our performance guarantee: We promise that your photovoltaic system will deliver the expected performance for over 25 years.
Grid parity translates to network equivalency and refers to a threshold. "Grid Parity" is given when the power from the photovoltaic system can be produced at the cost of the purchase of a conventional electricity producer.
Since this value was already undercut several years ago, the electricity from photovoltaic systems for their owners is cheaper than the purchase of power from an electricity supplier.
The "Merit Order Effect" aims to ensure that expensive and environmentally damaging power plants are the first to be disconnected from the grid if the electricity supply is covered.
The answer is clearly: yes! Because the cost of electricity that you produce with photovoltaics is lower than electricity suppliers' electricity prices (see Grid Parity). Not only OeMAG - the green electricity processing center - has lowered its remuneration rates, but photovoltaic systems have also become cheaper to buy.
In addition, independence from the electricity market and a return of around 10 percent make photovoltaics even more attractive!
Solar energy is - unlike fossil fuels such as gas and oil - available in unlimited quantities and also produced on site. Despite all the opposition, solar power systems make an important contribution to the protection of the environment, not least because they produce without emissions and thus reduce pollutant emissions.
The fact that even the production of the solar power systems themselves affects the environment was refuted by several researches. Even if the production of the plants themselves requires energy, this is paid back after around two years - from then on, the energy gain begins.
The CO2 savings of photovoltaic systems represent a comparative value for power generation from fossil energy sources.
For a photovoltaic system with 3 kWp, the following values result:
- CO2 savings per kWh: 0.6kg CO2
- Annual CO2 reduction: 0.6 kg / a x 4,500 kWh / a = 2,700 kg per year
- Annual supply to the power grid: approx. 4,500 kWh
In concrete terms, a 1,000-watt PV system prevents the emission of around 500 kg of CO2 per year.
Photovoltaic modules contain a large amount of recyclable materials such as aluminum and glass. With appropriate disposal, a large part of it can be recycled for the production of new solar modules.
The professional disposal of solar modules is guaranteed by UFH, of which Energy3000 solar is a member.
