  2. Solar tracker - Wikipedia

    en.wikipedia.org/wiki/Solar_tracker

    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 ...

  3. Nextracker - Wikipedia

    en.wikipedia.org/wiki/Nextracker

    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]

  4. Heliostat - Wikipedia

    en.wikipedia.org/wiki/Heliostat

    Heliostats should be distinguished from solar trackers or sun-trackers that point directly at the sun in the sky. However, some older types of heliostat incorporate solar trackers, together with additional components to bisect the sun-mirror-target angle. A siderostat is a similar device which is designed to follow a fainter star, rather than ...

  5. Maximum power point tracking - Wikipedia

    en.wikipedia.org/wiki/Maximum_power_point_tracking

    From basic circuit theory, the power delivered to a device is optimized (MPP) where the derivative (graphically, the slope) dI/dV of the I-V curve is equal and opposite the I/V ratio (where dP/dV=0) [13] and corresponds to the "knee" of the curve. A load with resistance R=V/I equal to the reciprocal of this value draws the maximum power from ...

  6. Sun sensor - Wikipedia

    en.wikipedia.org/wiki/Sun_sensor

    Non-linear Sun sensor used by the TET-1 German microsatellite.. A Sun sensor is a navigational instrument used by spacecraft to detect the position of the Sun. [1] [2] Sun sensors are used for attitude control, solar array pointing, gyro updating, and fail-safe recovery.

  7. Solar panels on spacecraft - Wikipedia

    en.wikipedia.org/wiki/Solar_panels_on_spacecraft

    Spacecraft are usually designed with solar panels that can always be pointed at the Sun, even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going. A tracking mechanism is often incorporated into the solar arrays to keep the array pointed towards the sun. [1]

  9. Photovoltaic mounting system - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_mounting_system

    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.
