slew drive used in solar tracker system
Solar trackers are the devices used to adjust photovoltaic panels toward the sun to utilize more sunlight. They enable solar modules to remain in the best position to accumulate maximum energy from the sun. The application of tracking technology allows solar panels to follow the movement of the sun and increase electricity production as compared to a stationary array. Solar trackers are attached to solar panels to adjust their positioning against the daily passage of the sun throughout the year as the weather and seasons change.
Solar tracker comprises of several parts including sun tracking algorithm, control unit, positioning system, slew drive mechanism system, sensing devices, wind guard, tubes, and rods. Growing demand for energy supplemented by fluctuating fuel oil prices, increase in efficiency of solar panels by the use of solar trackers and increased product demand are expected to bolster the overall solar tracker market growth. Government incentive for the use of renewable energy sources as a mode of power generation and feed-in-tariffs is also likely to attribute to drive the market growth in the coming years. Impacts of harsh weather on the solar trackers coupled with the high initialization costs are some of the factor that is likely to constrain the market growth. However, upcoming advanced techniques are estimated to overshadow the restraints in the coming two to four years.
Single axis tracking technique is expected to dominate the MEA market over the coming years. Simplicity and lesser cost has helped single axis tracker sustain relentlessly over the past couple of years. Dual axis tracker incurred high maintenance costs which led to their dampened market growth. Growing demand for renewable energy sources in the countries across MEA is estimated to generate substantial demand for solar energy which in turn is likely to fuel market growth in the next two to five years.
