Solar Panels – Questions And Answers
Mounting
Installation of solar panels takes several days.
Typically solar panels are installed on roofs of buildings in order to save valuable space. At the same time achieve maximum orientation of solar panels on the south and choosing the angle of inclination close to 45o.
Installing solar panels and determine its size must be implemented in such a way as to be negligible effect giving the shadow of neighboring buildings, trees, power lines, etc.
An important part of the solar system is a supporting frame for solar panels. It provides the correct angle panels, as well as the necessary structural rigidity. The combination of the supporting structure with solar modules is done in order to withstand wind and other adverse environmental impact.
Mounting Options Installation:
* Tilting (on the roof with any slope angle)
* The horizontal (on the flat roof)
* Freestanding (solar panel with a support structure)
* Integrated. United with the network system can be part of the building structure. Moreover, integration into the building can be a great way to improve the architecture of the building and show that the elements of the building structure can also perform the function of generating electricity. For these applications are developed and produced special designs.
It is also possible installation of a hybrid system (wind generator + solar panels).
What is a solar panel (photovoltaic module)?
Solar panel is a device for converting of sunlight into electricity.
How durable is the solar energy system?
For photovoltaic modules (solar panels) manufacturers give 10-12 years to provide power for more than 90%, and 25-30 years to provide power for more than 80%. But, in fact, photovoltaic modules work for 50 years or more. The remaining elements of the system – it all depends on the manufacturer and product.
Where better to place solar energy systems?
Solar panels are usually located on the roof or supporting structure in a fixed position. It should be borne in mind that the sun moves from east to west, has a different angle in the summer and winter. When you install solar panels usually take as a basis angle latitude areas, where the object is.
What payback period of solar power?”
It depends on several factors. First, wired to learn if you have common network or object is not electrified at all. Secondly, the continuing increase in electricity prices payback periods vary. Because you want a detailed energy audit.
How much will it cost solar power system, if the daily consumption of object N kw / h?
Is it possible to install first a solar energy system with a small number of photovoltaic modules, and later build number?
Yes, of course. Addition of photovoltaic are is not a problem. You only need to look at the possibility of a charge controller and inverter.
No doubt electricity has an important place in our lives. In many cases people would like to have an independent or alternative heating supply source. If you are one of those who search information on hot water solar panels, please go to this site. There you may discover lots of details about ground source heating and how to purchase it.
Today the web technologies provide us with a really unique chance to choose what one requires for the best price on the market. That is why if you are properly armed with the info in your topic you can rest assured that you will always find the solution to any bad situation. So, please make sure to visit this blog on a regular basis or – the easiest way to take care of it – sign up to its RSS. Thus you will have your hand on the pulse of the recent informational updates about renewable energy here. Blogging can be helpful, you just need to understand how to use it.
