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 ...
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]
These mounting systems generally enable retrofitting of solar panels on roofs or as part of the structure of the building (called BIPV). [2] As the relative costs of solar photovoltaic (PV) modules has dropped, [3] the costs of the racks have become more important and for small PV systems can be the most expensive material cost. [4]
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.
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.

An automatic weather station (AWS) is an automated version of the traditional weather station, either to save human labor or to enable measurements from remote areas. [1] An AWS will typically consist of a weather-proof enclosure containing the data logger , rechargeable battery , telemetry (optional) and the meteorological sensors with an ...
