along with the increasing progress of photovoltaic technology, the continuous improvement of the national policy and the cost of stable gradually, more and more photovoltaic enthusiasts and even ordinary residents is itching to rooftop photovoltaic power station, but many consumers in the mind is in the north have doubts, we this to the illumination time really suitable for installation of photovoltaic power station?
according to the national aeronautics and space administration NASA's meteorological data, different longitude and latitude regions have different irradiance, China belongs to one of the country is rich in solar energy resources, the total area of more than two-thirds district in rizhao number more than 2000 hours, annual radiation dose in more than 5000 mj/m2. China's northern region belongs to the category ( A rich resources) , radiation throughout the year in 5400 ~ 6700 mj/m2, suitable for installation of photovoltaic power generation system. With the progress of photovoltaic technology, even in a bad light, electricity is very secured, can bring the excess earnings for the customer.
haze weather now is very common, many people will have this kind of worry, fog haze weather, the sun photovoltaic systems will not be able to power generation are not see? Actually these worry is unnecessary. Fog for photovoltaic do have certain effect, but for the influence of the power generation efficiency is less than 5% ( Heavy fog except) 。 It is because the fog haze, can't see the sun every day, country to vigorously develop renewable energy photovoltaic power generation. Because our country at present the main power supply way for thermal power, pollution is bigger, assuming that every household can install photovoltaic equipment, daily output of 15 degrees (default Power: 5 kw) , thermal power, can reduce about 40% a year, the environment is improved slowly, everyone is far away from the smog.
these photovoltaic products after installation requires little maintenance and management, the service life of the photovoltaic modules will typically have more than 25 years, just clean occasionally, and it's self cleaning ability is strong, as long as the next rain, occasionally components will become very clean.
