Solfångande

Solfångande, also known as solar tracking, is a technology used to optimize the performance of solar panels by aligning them with the sun's position throughout the day. This process involves the use of mechanical or electrical systems that adjust the orientation of the solar panels to maximize sunlight exposure.

There are two main types of solar tracking systems: single-axis and dual-axis. Single-axis systems track the sun's movement along a single plane, typically east to west, while dual-axis systems track the sun's movement along two planes, both east to west and north to south. Dual-axis systems are more efficient but also more complex and expensive.

Solar tracking can increase the energy output of solar panels by up to 40% compared to fixed-mounted panels. This is because solar panels generate the most electricity when they are perpendicular to the sun's rays. By tracking the sun, solar panels can maintain this optimal angle throughout the day, even as the sun's position changes.

However, solar tracking systems also have some drawbacks. They require additional hardware and maintenance, which can increase the overall cost and complexity of solar panel installations. Additionally, the tracking systems can be affected by weather conditions, such as strong winds or heavy snow, which can reduce their effectiveness.

Despite these challenges, solar tracking remains a popular and effective way to improve the efficiency of solar panel systems. As solar technology continues to advance, it is likely that solar tracking will become an even more important aspect of solar panel design and installation.
