Due to wind data is essential for documenting eddies and protecting wind turbines, wind turbines need accurate wind operating information in order to operate safely. 300W wind turbine with low starting wind speed and low running vibration. When the anemometer speed does not change rapidly, such as when the bearing belt is faulty, the eddy current cannot be accurately measured. The turbine control system adjusts the blade spacing and rotor speed separately according to the degree of turbulence in order to protect the blades and drive mechanism from fatigue damage caused by improper use of rotating blades.
Monitoring the solar Photo-Voltaic system is a very important matter because it shows you how much electricity saving you got from your solar system, in addition, it assists you knowing if the system is running properly producing its rated power or it may have a fault, so you can take a rapid troubleshooting action.
The sun light is a range of spectrum; it consists of units called photons. When these photons strike the solar cell surface, they can be absorbed by the cell or reflected by the cell. The absorbed amount of photons will be converted to electricity as described above, and the reflected amount are just a waste with no benefits. So, when solar cell manufacturer wants to increase the solar cell efficiency, he is trying to reduce reflected amount of photons, and increase the absorbed amount of photons, and nowadays there are ongoing different technologies aim to increase the solar cell efficiency, and moreover, they are developed day after day via scientists and original designer manufacturers.
When installing solar photo-voltaic (pv) system on the roof of your new home, you need to be careful about shading.
Solar inverter is a main device and important part of PV on grid power system. In order to ensure the normal operation of the solar PV grid tie system, the correct configuration and selection of solar inverters are particularly important. For the configuration of the solar inverter, in addition to considering the technical specifications of the entire photovoltaic power generation system and referring to the product manual, the following technical features should also be considered: rated output power, output voltage adjustability, overall efficiency and start-up performance.
Solar inverter is an electronic product and its service life is limited due to the limit of the components. However, many inverters are damaged before the service life expires and the actual service life is shorter than the designed theoretical service life. The service life is determined by the product quality and the post-period installation, operation and maintenance conditions. So, how to improve the service life of the solar inverter?
Solar inverter shall realize the highest efficiency in wide power range conditions. Meanwhile, using a solar inverter shall meet the strict safety requirements. The property of the solar inverter is essentially determined by the accurate measurement of basic electricity. The safety criteria that shall be followed by solar inverter designers may become stricter and stricter. For instance, just like the limit on the input of DC power into the grid, some consensus may be reached on the allowable total harmonic wave of the solar inverter output current. By far, many different local limitations are put forward based on the layout situation. Thus, it requires that when the power grid frequency is greatly higher than 50Hz or 60Hz, the current shall be measured accurately.
The AC voltage overrange is the most common failure of the solar inverter connected with the PV grid system. This is because the grid voltage is not constant and it will change with the changing of the load and current. At the same time, the output voltage of the inverter will be affected by the grid voltage. When the grid encounters abnormal situation, the inverter power supply shall be stopped to avoid more serious damage on the grid.
Power inverter has many specifications, and these specifications usually include rated power and peak power. The rated power is the continuous output power, which refers to the power that the inverter keeps working for a long time. The peak power is the starting power, which is generally twice the rated power. It is mainly used to meet the instantaneous peak value when individual home electrical appliances are started. For example, for a power inverter with 2000 watts continuous power, its peak power can reach 4000 watts. Therefore, for an inverter, its peak power must be able to meet the instantaneous power when the home appliance starts to ensure normal operation. When selecting an inverter, its power should be higher than the starting power of the home electrical appliances used. When working, the inverter itself consumes part of the power. Its input power is greater than its output power. For example, if an inverter inputs 100 watts of direct current and outputs 85 watts of alternating current, its efficiency is 85%.
The working conditions of centrifugal pumps are generally harsh. Affected by environmental conditions, mechanical vibration and other factors in the working process, its technical status will undergo different changes. The maintenance of the water pump is to tighten and adjust the place that should be tightened and adjusted before the normal technical state of the unit itself is damaged. In addition, it is necessary to change the lubricating oil promptly to maintain normal lubrication conditions; frequently observe various instrument monitoring devices. If any problem is found, the fault should be eliminated in time, so that the unit is always working in good technical condition. Only in this way can the service life of the water pump unit be prolonged and the unit can work with high quality and high efficiency.
Usually the main reason of installing the solar photovoltaic system is to produce electricity to be used in different applications. Some people lives in remote locations which are not serviced by the main electric grid, and using solar photovoltaic system for those people is a very reliable and cost effective way of electricity generation, it’s very less expensive than making extensions (installing poles and cables) to get electricity from the nearest main grid power supply.
Electrical power providers are generally providing two different tariff structures, the first is called flat rate structure, in which the price for the purchased kWh is fixed, its same over 24hours/7days. And the other structure called time of use, in which the price for the purchased kWh differs from time to other, there will be off peak price and high peak price. Usually, off peak time is in the night, high peak time is from afternoon to the evening, and the normal time is represented by the rest of the day hours, in some areas, the high peak kWh charges may reach 50 cents per each kWh. Therefore, we must choose a reasonable electricity price according to our own needs.
The inverter is the heart of the solar photovoltaic system, and more than 90% of solar system failures causes is due to inverter malfunction. There are 2 main factors affecting solar inverter selecting; inverter performance and its price.
The solar panel spend its life in rains, hot sun, etc. It works outdoor and exposed to harsh environment in summer and winter. These changes in weather will of course affect the solar internal components and material bonded to each other, there will be chemical changes which will affect not only the solar panel performance, but it will affect its life time, its efficiency and reliability, because these chemical reactions will create new chemical material. Moreover, the elasticity of these internal materials will change with the time pass and affect the tension and stress forces taken place between different parts.
So, the cheap low quality solar panel which uses cheap and low quality materials, and which its manufacturer has not taken into consideration the parameters aforementioned will not withstands/survives much, provides low performance and low service life.
If your building/house is heavily shaded. As the shadow will dramatically reduce the solar system generated output electricity. In your vision you have to take care and consider about the impact of the current shadow and the anticipated shadow comes from trees grow or known renovations and extensions in surrounding buildings, that what we called shadow analysis study. It is an important study assisting us deciding whether the solar system will be a good beneficial investment project that worth to proceed or not. One more thing to note, is that in case of locations subjected to such shadow, its recommended to use micro solar inverter, so you can distribute your solar panels freely and avoid areas with heavy shadow.
