DayChase - Single Axis Tracker

RC1P & RC2P

Independent row 1P & 2P multi drive tracker

East to West self-rotating PV structure, programmed to avoid inter raw shadow effects, programmed to capture diffused light & to self-position at extreme weather condition are called Single-axis controlled Tracker.

After years of global OEM supply experience of key tracker parts & Design involvements, We are offering a well competitive, Maintenance free, Qualitative & sturdy trackers for small to large projects. Our trackers are FEA & CFD analysed + rigorously tested for life expectancy & sturdiness. Our indigenously manufactured each Tracker parts & control unit are made to compete the large international players in terms of reliability & after sales need. We achieve economy of supply through scale of integrated single location production facility.

Static Analysis

FEA & Staad analysis as per IS & ASTM code. We also undertake joint analysis.

Dynamic Analysis

Aro-elastic wind instability analysis by CFD Modeling

Life Cycle Tests

Vigorously testing expected life, wear cycles, load capacity, environment effects for drive
parts.

Advantage of Single axis Trackers:

+ PV panels mounted on Single axis-Trackers would produce significantly higher power during early morning & late evening hours by rotating the panel in direction of sun.

+The diagonal rays of sun in morning & Evening hours have unbelievably high capacity to produce power(> 60% intensity than midday at sun position only 15° above horizon). The milder temperature in morning & evening hours helps drastic increase in efficiency of Photovoltaic solar cell.

+Our 1P trackers are especially advantageous for bi-facial modules to capture reflecting sun light & to avoid shading effect on rear side of modules.

+Our 2p Tracker offers additional benefits of better use of ground, shorter raw length, and higher module height for better cooling & higher reflection on rear side. The 2p Bi-facial tracker is estimated to supply at least 2% higher output compared to 1P Bi-facial tracker.
