the energy crisis has renewable energy and especially the solar power brought back into focus. the rising electricity price and the government promotion have led to the demand for solar systems of all sizes has further increased. There PV systems have only been established for some time, not so much is known about them Maintenance and Care known. Basically the facilities low maintenance and must not cleaned will. There is also special caseswhere regular cleaning makes sense.
Solar power has a future
Next to the wind energy is the solar power best to “clean energy production” suitable in the Federal Republic. True will be a lot energy and rare raw materials For the production of wind power plants and PV modules needed, but it is clear for the climate and the environment better, Renewable Energies preferable to fossil fuels. While wind turbines pay off because of their efficiency, especially on a large scale, solar power even on a small scale can be gained meaningfully.
Meanwhile in Germany in every small village solar systems to find. In general, the modules on South-facing roofs Installed. But also the installation of solar systems on roofs with West-East orientation and flat roofs is gaining popularity. In this country it is advisable to have one tilt angle aim for between 30° and 40°. That’s not the only one Yield maximizedbut also the Maintenance and care costs minimized.
the good efficiency and the low maintenance do solar power to the all-rounder of renewable energies. The energy of the sun is in small as well as in big scalewith or without battery usable and is available on many properties in Germany sensible.
Maintenance and Care
Also the low maintenance and care costs speaks for photovoltaics. Are the modules in the recommended tilt angle installed, they must in most cases not cleaned will. The regular Rain washes the impuritieswhich are mostly due to fine dust or Saharan dust, simply gone.
Only in rare cases it will be necessary to add the modules clean. impurities like bird droppings or soot from the neighboring fireplace should be best with one soft clotha lot of water and neutral soap be removed. solar systems, the installed horizontally are, should cleaned more often will. If you notice that the The efficiency of your system decreasesyou should start with a visual inspection make. If it becomes necessary to clean the solar panels on the roof, it may be advisable to use a professional to call. In the meantime, many companies and self-employed have specialized in cleaning solar systems.
PV systems are generally very low maintenance and have an estimated lifespan from more than 30 years. Is it apparent that the Modules cleaned on the roof need to be done, you should leave that to the professionals. The cleaning in itself is not difficult, but it is not worth a few kilowatt hours to climb around unsecured on your own roof.
Functionality of the PV system
Generally speaking, the functionality a solar system very easy – regardless of whether it is an industrial plant or a single solar module: light falls on it solar panelwhich direct current generated. This is done using a inverter in alternating current changed and can then directly in private power grid used, stored or ins public network be fed.
Most solar cells will made of silicon. Silicon is the most abundant mineral in the earth’s crust and is considered inexhaustible. become from the material slices Manufactured on top and bottom with foreign atoms – mostly boron or phosphorus – contaminated will. When solar energy falls on the discs, electrons collect on one side and protons on the other side of the disc. arise plus and minus pole. Becomes a consumption device connected, flows electricity.
The relative easy manufacturethe simple functionality and the good efficiency do Photovoltaic irreplaceable. Since the cells already electricity when there is little sunlight deliver is her Deployed in most regions of the world conceivable. They have become indispensable in remote regions of the world to which there is no power cable.
outlook
Generally it can be said that you usually do not have to worry about the maintenance and care of the solar system must. Because of the preferred Installation at a certain angle of inclination the rain washes the light impurities off the modules. Only in the rare cases will that active cleaning necessary.
As the owner of a PV system, you should only regularly check the amount of energy gained. Remains the average amount of electricity generated over the years evenis this No need to clean the system. Is a unexpected kink in electricity production, you can further steps test. In that case, your best bet is to get yourself Advice from an expert.
So far there is few long-term studies on cleaning PV systems. while some counselor recommend the plants all 3 to 5 years to clean, others refer to the self-cleaning effect. You should only take action if the efficiency of the solar system decreases significantly.
