The pool of solar household solar power generation equipment plate temperature should not be ignored

It is well known that the solar panels at higher temperatures, the open circuit voltage to drop, the output power will be reduced. So some design method in the last square capacity, considering the influence of the solar panels, temperature coefficient, thus increase the capacity. Guangdong, for example,

it is well known that when the temperature of the solar panels rises, its open circuit voltage drops, the output will decline. As a result, some design methods in the final phalanx capacity when considering the influence of solar panels, temperature coefficient, thereby increasing the capacity. Guangdong energy technology co. , LTD. , said, for example, as the temperature rises, the output power of solar panels will decline, so the requirement system even under the highest temperature to ensure the normal operation. Therefore, the standard test temperature ( 25℃) Shall be equal to the square of the output power under the phalanx of the annual work under high temperature. This is obviously a conservative approach. 36 solar panels, in fact, the current series of standard module of the working voltage of about 17 v to 12 v battery charging, have considered the antihypertensive effect of temperature during the summer. In addition, the summer solar radiation intensity is higher, usually rectangular array of power generation tends to be redundant, it can fully make up for the power decrease caused by temperature rise. Therefore, when calculating the capacity of solar panels, it is not necessary to consider the effect of temperature. Under special circumstances, such as in tropical areas such as design photovoltaic system for Africa, generally increase the safety factor of the system is enough. Should be considered only in rare cases, increase the number of solar panels component series batteries. However, when the temperature is lower, the output of the battery capacity will be affected, the winter when working temperature is lower than 0 ℃, should be appropriate to consider heat preservation.
