In April 2024, Nextracker introduced a solar tracker system with a carbon footprint that is up to 35% lower than traditional trackers. The low-carbon tracker system, which is produced with an electric arc furnace manufacturing process and uses recycled steel, received the Carbon TrustProduct Carbon Footprint Label certification.

The effective collection area of a flat-panel solar collector varies with the cosine of the misalignment of the panel with the Sun.. Sunlight has two components: the "direct beam" that carries about 90% of the solar energy [6] [7] and the "diffuse sunlight" that carries the remainder – the diffuse portion is the blue sky on a clear day, and is a larger proportion of the total on cloudy days.
Power/Voltage-curve of a partially shaded PV system, with marked local and global MPP. Maximum power point tracking (MPPT), [1] [2] or sometimes just power point tracking (PPT), [3] [4] is a technique used with variable power sources to maximize energy extraction as conditions vary. [5]
[1] [2] Sun sensors are used for attitude control, solar array pointing, gyro updating, and fail-safe recovery. [3] [4] In addition to spacecraft, Sun sensors find use in ground-based weather stations and Sun-tracking systems, and aerial vehicles including balloons and UAVs. [2]
Their first system was a linear-trough concentrator system that used a point focus acrylic Fresnel lens focusing on water-cooled silicon cells and two axis tracking. Cell cooling with a passive heat sink and use of silicone-on-glass Fresnel lenses was demonstrated in 1979 by the Ramón Areces Project at the Institute of Solar Energy of the ...
Most solar parks are ground mounted PV systems, also known as free-field solar power plants. [51] They can either be fixed tilt or use a single axis or dual axis solar tracker. [52] While tracking improves the overall performance, it also increases the system's installation and maintenance cost.

The "Track Rack" solar tracker which Baer and Zomeworks staff developed is a metal-framed passive-solar dynamic mounting for photovoltaic (PV) modules. With an arrangement of cylinders, pistons, and tubing, the device uses the differential pressure and movement of entrapped liquid to enable gravity to turn the rack and follow the sun.
