After the solar photovoltaic need to consider various factors of solar generating capacity, only to master the accurate information in order to determine the installation of solar panels, lowest power, size (effective power output of solar panels to be too much in daily electricity load ) and the battery capacity, performance and control. The product to achieve the best price. If estimates of the relevant factors of mistakes, it will directly affect the independent photovoltaic power generation system performance and cost. Optical resource contains high as 96.64%. Contains the amount of resources from our point of view can be developed, recognized scholars and experts compare figures, 100 million kilowatts of biomass energy prices for household solar power, hydropower 378 million kilowatts household solar power generation cost, 253 million kilowatts of wind power, and solar energy is 2.1 trillion kilowatt solar energy, just develop one percent to reach 21 billion kilowatts namely; its proportion of view, only 0.46 percent biomass, wind power accounted for 1.74%, 1.16% and hydropower, and photovoltaic solar power plant for 96.64% of household price | TIANHUI Giant Technology (certified) | Xiaogan provided by Wuhan Solar Energy Technology Co.
