Economic efficiency depends of photovoltaic systems, yield and solar calculator of yield of photovoltaic systems the factors sunlight, used solar module, angle and orientation of the modules. With a solar calculator, income, taking into account these factors is to calculate. The purely financial income is also promoting solar energy. As the conditions change, also the date of commissioning plays a role. Cell types standard photovoltaic solar calculator with the postal code for Sunshine expected, the date of commissioning for the calculation of feed-in tariff, the type of surface (roof, lean-to roof, flat roof, conversion area or other open space), the usable surface area in square meters, roof alignment (direction), and the roof slope in degrees as basic factors. The type of solar cells is not specified in the computer, to differentiating the differences fall out. Also the shading is not included, it is precisely not to calculate.
The Cell types of the solar modules but in the consideration should be included. A distinction is basically mono – and polycrystalline, and amorphous cells. Poly-crystalline cells are inexpensive, they can achieve very high efficiency. Flat rate to say Mono-crystalline or amorphous cells have a higher efficiency than polycrystalline cells, 2011 no longer true in the year. The manufacturers have gone different ways in development and have achieved some outstanding results on different technological base. In March 2011, the final test by foundation oko Test said that the modules produced in Germany independent results consistently very good and good by their technological base. Solar Calculator: Structure of input because the solar modules constantly evolving in the competition, those data entered in a solar calculator, which remain constant in the construction of photovoltaic systems. These are the geographical conditions and the type of surface, mainly roof alignment and tilt.
The client should only in the Mind keep, with more or less there efficiency systems, contributes to which also the inverter, and will keep the plant over a period of 20 years. The photovoltaic systems work most efficiently when they point directly towards the South. But work very well, also South-East and South-West and South West is somewhat preferred. The yield may be lower in these two areas by up to 20 percent. The roof slope also affects the yield, it is 45 optimally. The difference in yield but more by the direction when influenced by the tilt also flat roofs can provide a satisfactory yield. In a sample calculation a pent roof just south-facing with an inclination of 45 about can yield 6-7 per cent more than in the weakest version of the 15 tilt. All factors together can make a big difference in yield of course, the journal energy dispatch calculated for this extreme differences of up to 500 percent. That’s up about Profit or loss of the plant.
