Sharp will be listed capacity increase and set the time of the solar cell module Increase the battery unit the number set to increase capacity

Simian sloping roof solar panel  module is set, if only rectangular modules, will produce idle space appears, also the problem of poor appearance. On the other hand, the conventional corner module can make full use of space, but the output power is small, so in some cases, up to the desired setting capacity for less than household. Sharp analysis, it is precisely because of these problems, consumers are often reluctant to set surrounded by sloping roofs of residential solar cell module.

        Sharp on the new solar cell module in order to overcome the difficulties, to adjust the number of battery cells of the detachment module. Rectangular "NU-172BB" and "NU-122CB" the output power is increased by about 3%. Surrounded by sloping roof corner pentagon modules (corner modules) NU-081LB "and" NU-081RB "increased by approximately 31%.

        For example, in the transverse width of 8.2 meters, about 6.4 meters deep, the slope is 45% surrounded by sloping roof on the combined set of these modules can produce 4.17 kilowatts of output power. Under the same conditions, and if it is a conventional product, the output power inverter  was 3.76 kW. Therefore, the set capacity is expected to increase by approximate ly 11%. Sharp said power regulator (the JH-45CD3P, JH-40CD3P) to reduce the power loss by using a combination, to increase the power generation amount.

Single-crystal solar cell module
Model suggested retail price of the nominal maximum output power
Of NU-172BB 172W 8.568 million yen
Of NU-122CB 122W 6.69 million yen
NU-081LB 81W 4.788 million yen
NU-081RB 81W 4.788 million yen

The (Nikkei residential construction Reporter: the Yasui power), Sharp will be listed on October 10 improved set the capacity of the single crystal solar cell module NU-172BB, NU-122CB "," NU-081LB NU-081RB ". New products to adjust the design of the solar cell module, Sharp estimates, about 11% set capacity than ever before. Another feature of the new product, the installation and construction of the newly developed method can be set-up time reduced by about 20%. Sharp said, is surrounded by sloping roof due to many family residential, may be due to lack of set capacity and set time-consuming issues such as to give up the use of solar cells, and therefore the proposal will be active for this family.

Instead with horizontal ribs supporting the way

        New installation construction method, for setting the new solar cell module is adjusted to the fixing method of the module. Conventionally set on the roof transverse edge, the transverse rib and the module is fixed with a plurality of metal fittings. The new method is no longer used metal parts into a module with horizontal ribs support, thus making it possible to reduce the number of components and the amount of work.

        Sharp said, set 4 kW module in the ordinary surrounded by sloping roof, from transportation, construction to verify that the operating results, takes about 10 hours, new construction method, the estimate can be completed in less than eight hours set shortened by about 20 %. Minister of solar energy systems business of rice paddies week on the advantages of the new product, stressed that the average the complete circuit construction time is shortened, even the complex shape of the roof,grid tie inverter but also can be used one day to be completed, also can reduce the labor costs of the construction.

        At this stage, this installation and construction method is based on a new product module for the object. By changing the fixed metal roof accessories, will not only be used for the inhalation of asbestos roof tile roof and metal roof can also be used.
