Abstract

In this paper, 1-axis tracking mechanism of solar-cell panel, which is able to rotate from -90 degree to +90 degree for maintaining always perpendicular between solar-cell panel and sun, was analyzed. This paper propose the non-linear shaped guidance and analyze mathematical formulation of non-linear shape. This analysis shows that it is able to identify the non-linear shaped guidance. Especially, even though the length of rotating link have changed, the non-linear shaped guidance could be confirm with proper size. As effectiveness of this result, 10% efficiency rising is estimated compared to the conventional 1-axis tracking mechanism and also optimal non-linear shaped guidance can be suggested for various size of solar-cell panel. Therefore the flexible mass-production is possible for various size of non-linear shaped guidance.

본 논문에서는 태양전지를 태양과 항상 법선 방향이 되도록 하기 위해 수평방향으로 놓여진 태양전지판을 ${\pm}90^{\circ}$까지 대칭 회전 가능토록 하는 비선형형상의 가이드홈을 가진 단축 추적장치를 제안하고, 비선형형상에 대한 수식을 정립하고자 한다. 그 결과 가이드 홈의 비선형 형상을 확정할 수 있었고, 특히 회전 링크의 길이가 달라져도 회전링크의 길이를 반영하는 가이드 홈을 정확히 확정할 수 있다. 이를 통해 기존의 1축 추적장치에 비해 약 10%이상의 태양전지 효율향상이 가능하며, 또한 어떤 크기의 태양전지판에 대해서도 최적의 비선형 형상 가이드 홈을 갖는 가이드 부재를 제공할 수 있고 대량 생산도 가능하다.
