The answer is not worth it. Ordinary users use solar panels mainly to pursue cost-effective, for the sun tracking solar panels are not suitable for use in the public, more photovoltaic power stations built on a large scale.
Sun tracking solar panels are power generation devices that can adjust the angle of the solar panel according to the changing position of the sun to ensure power generation efficiency.
Sun tracking solar panel is composed of two photoresistors, motor, and a simple central circuit board, as the sun moves to different sides of the photoresistor with different light intensity, the change of photoresistor leads to the change of current motor drives the solar panel to rotate when the solar panel is facing the sun when the motor stops working.
High power generation efficiency, sun tracking solar panels can automatically adjust the angle with the movement of the sun, so that the power generation efficiency continues to be maximized. Sun tracking solar panels are divided into single-axis and dual-axis, single-axis solar tracking solar panels can only realize horizontal rotation, dual-axis solar tracking solar panels can realize horizontal and vertical adjustment of two angles.
The single-axis solar tracking system improves power generation by about 20% per day compared to conventional solar power, and the dual-axis solar tracking system can even improve it by 30% to 40%, and this gap will be even greater as the sun’s intensity increases.
(1) expensive, due to the addition of automatic steering system than traditional solar panels are also much more expensive, a dual-axis solar panel tracking system costs about 2 times higher, bringing an additional 35% of the power boost. Solar panels themselves payback time of about 6 years price increases lengthen the cycle of solar panel cost recovery.
(2) High maintenance frequency, due to the addition of electric regulation system, need to spend more time and energy to maintain.
(3) Site requirements, the general power of the larger sun tracking solar panels required to be installed on the ground, the limited space on the roof is not suitable for installation.
At this stage, the sun tracking solar panels due to technical immaturity, in the public implementation is not universal, mainly used in national photovoltaic power stations and RVs automatically tracking solar panels, while the field air humidity detection system and other power consumption of low power sensors will also be used. Of course, simple single-axis solar tracking solar panels can also be modified to use their own, the principle is very simple.
The fixed angle of the traditional solar panel limits the output of solar energy efficiency, in the future if the solar panel efficiency can achieve a substantial breakthrough is expected to become a mainstream solar tracking system industry.
The sun tracking solar panels will indeed improve power generation costs are also more expensive, comprehensive consideration of the sun tracking solar panels at this stage is not worth it.
