In 2024, Nextracker introduced tracker technology that uses weather-forecasting data and AI to automatically adjust solar panel angles into a stow mode ahead of hailstorms to avoid direct hits. [11] [12] The product was developed to mitigate the rising cost of insuring solar arrays from hail and other weather-related damage. [13]
A solar tracker is a device that orients a payload toward the Sun. Payloads are usually solar panels , parabolic troughs , Fresnel reflectors , lenses , or the mirrors of a heliostat . For flat-panel photovoltaic systems , trackers are used to minimize the angle of incidence between the incoming sunlight and a photovoltaic panel , sometimes ...
Solar tracker. Solar trackers increase the energy produced per module at the cost of mechanical complexity and increased need for maintenance. They sense the direction of the Sun and tilt or rotate the modules as needed for maximum exposure to the light.
The California Valley Solar Ranch (CVSR) is a 250 megawatt (MW AC) photovoltaic power plant in the Carrizo Plain, northeast of California Valley. The project is owned by NRG Energy, and SunPower is the EPC contractor and technology provider. The project constructed on 1,966 acres (796 ha) of a 4,365-acre (1,766 ha) site of former grazing land.

More than 3 million thin-film CdTe photovoltaic modules from First Solar and 138 skids designed and manufactured by Elettronica Santerno are used. [6] It was the world's largest solar project using single-axis trackers to follow the path of the sun upon completion. [7] [8] The cost for this first unit was $365million.

PV solar systems have varying relationships to inverter systems, external grids, battery banks, and other electrical loads. [6] The central problem addressed by MPPT is that the efficiency of power transfer from the solar cell depends on the amount of available sunlight, shading, solar panel temperature and the load 's electrical characteristics.
