Japan starts her solar power station recently
Evidence in Wakkanai city facilities, also carried out taking into account the snow on the impact of solar cell experiment. Without taking any measures, the solar cell modules will be gradually covered by snow. If so, the electricity will be significantly reduced. So, take the elevated rack units, increasing the interval between the module and the ground, or set the gap between the module and the module so that when the snow down to wait for improvements. In addition, when the surface of the glass and frame module with the level of difference, you can learn from here whether there is snow. Therefore, adopting the resin to fill the module surface height difference, the countermeasures to facilitate snow fall. So far various methods have achieved some results.
There is also a snow countermeasures can be used as an effective way. This is the single-axis tracking solar cell systems. This is an action with the solar cells, solar cells change from east to west point of the system module. Originally aimed at optimizing the use of angle of incidence of sunlight and increase output power. Wakkanai city facilities are also used for snow removal of the system. For example, at night to increase the angle of solar cells, it is difficult snow conditions, snow fell early in the morning to join to promote action. However, the issue is single-axis tracking system, the cost of shelf units, compared with the general framework sets per kW to 1.5 to 2 times higher.
As for the cost-cutting on the shelf, juvenile facilities within the general framework is promoting Taiwan to cut the Department of the experimental material. Like with Hokuto City, the Department of material usage reduction is the key. In addition, measures must be considered in the frame to be used as snow Height, and snow when the frame units durability. Weather conditions through unique Hokuto City, and snow and other severe weather conditions, Wakkanai City, empirical confirmation of two cities, “can be anywhere in Japan, building megawatt-class solar energy power stations.”
