Solar installations around the world are driven by custom designed systems developed by Joyce/Dayton. These competitive cost solutions may include:

The tracking system motion of the M18KD-20 Gearless Dual-Axis Tracker is based on the accuracy of the astronomical algorithm. This makes for maximum solar radiation intake even when it is cloudy, better quality and up to 40%-60% greater energy production compared to fixed tilt solar canopies, ensuring greater benefit per unit of installed capacity in comparison to conventional systems.

On Oct. 28, 2021, NCEI scientists out of CIRES observed a strong solar flare via the Solar Ultraviolet Imager (SUVI) on the GOES East satellite at 11:35 am ET. The flare produced aurora (northern lights) that were visible across Canada and as far south as Pennsylvania, Iowa, and Oregon. The JPSS satellites were able to capture imagery of these aurora via their VIIRS instrument, showing their extent.

Luckily, the Earth has a magnetic field that surrounds us like a protective bubble, deflecting most of this harmful radiation. The Sun, which is made of electrified gases called plasma, also generates its own magnetic field, and all solar activity is driven by these magnetic fields.

Sunspots are used as an indicator of solar activity, and the number and location of sunspots is used to track the Sun's overall activity. Although the Sun may look like a constant ball of light every day, it actually goes through a cycle of increasing and decreasing activity that lasts around 11 years.

NOAA satellites help monitor the activity of the Sun and when solar flares, or coronal mass ejections occur. Since these events can happen unpredictably and some can reach Earth within minutes, NOAA's Space Weather Prediction Center uses this information to monitor the activity on the Sun and makes forecasts, predictions, and alerts.

Solar panels work best when sunlight hits them directly. To capture as much energy as possible, many solar arrays actively rotate towards the sun as it moves across the sky. This makes them more efficient, but also more expensive and complicated to build and maintain than a stationary system.

Nowadays, most heliostats are used for daylighting or for the production of concentrated solar power, usually to generate electricity. They are also sometimes used in solar cooking. A few are used experimentally to reflect motionless beams of sunlight into solar telescopes. Before the availability of lasers and other electric lights, heliostats were widely used to produce intense, stationary beams of light for scientific and other purposes.

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.

In a solar-thermal power plant, like those of The Solar Project or the PS10 plant in Spain, a wide field of heliostats focuses the sun's power onto a single collector to heat a medium such as water or molten salt. The medium travels through a heat exchanger to heat water, produce steam, and then generate electricity through a steam turbine.

A somewhat different arrangement of heliostats in a field is used at experimental solar furnaces, such as the one at Odeillo, in France. All the heliostat mirrors send accurately parallel beams of light into a large paraboloidal reflector which brings them to a precise focus. The mirrors have to be located close enough to the axis of the paraboloid to reflect sunlight into it along lines parallel to the axis, so the field of heliostats has to be narrow. A closed loop control system is used. Sensors determine if any of the heliostats is slightly misaligned. If so, they send signals to correct it.

Smaller heliostats are used for daylighting and heating. Instead of many large heliostats focusing on a single target to concentrate solar power (as in a solar power tower plant), a single heliostat usually about 1 or 2 square meters in size reflects non-concentrated sunlight through a window or skylight. A small heliostat, installed outside on the ground or on a building structure like a roof, moves on two axes (up/down and left/right) in order to compensate for the constant movement of the sun. In this way, the reflected sunlight stays fixed on the target (e.g. window).

Heliostat costs represent 30-50% of the initial capital investment for solar power tower power plants depending on the energy policy and economic framework in the location country.[8][9] It is of interest to design less expensive heliostats for large-scale manufacturing, so that solar power tower power plants may produce electricity at costs more competitive to conventional coal or nuclear power plants costs.

One way that engineers and researchers are attempting to lower the costs of heliostats is by replacing the conventional heliostat design with one that uses fewer, lighter materials. A conventional design for the heliostat's reflective components utilizes a second surface mirror. The sandwich-like mirror structure generally consists of a steel structural support, an adhesive layer, a protective copper layer, a layer of reflective silver, and a top protective layer of thick glass.[8] This conventional heliostat is often referred to as a glass/metal heliostat. Alternative designs incorporate recent adhesive, composite, and thin film research to bring about materials costs and weight reduction. Some examples of alternative reflector designs are silvered polymer reflectors, glass fiber reinforced polyester sandwiches (GFRPS), and aluminized reflectors.[10] Problems with these more recent designs include delamination of the protective coatings, reduction in percent solar reflectivity over long periods of sun exposure, and high manufacturing costs.

One simple alternative is for the mirror to rotate around a polar aligned primary axis, driven by a mechanical, often clockwork, mechanism at 15 degrees per hour, compensating for the earth's rotation relative to the sun. The mirror is aligned to reflect sunlight along the same polar axis in the direction of one of the celestial poles. There is a perpendicular secondary axis allowing occasional manual adjustment of the mirror (daily or less often as necessary) to compensate for the shift in the sun's declination with the seasons. The setting of the drive clock can also be occasionally adjusted to compensate for changes in the Equation of Time. The target can be located on the same polar axis that is the mirror's primary rotation axis, or a second, stationary mirror can be used to reflect light from the polar axis toward the target, wherever that might be. This kind of mirror mount and drive is often used with solar cookers, such as Scheffler reflectors.[11][12][13] For this application, the mirror can be concave, so as to concentrate sunlight onto the cooking vessel.

The alt-azimuth and polar-axis alignments are two of the three orientations for two-axis mounts that are, or have been, commonly used for heliostat mirrors. The third is the target-axis arrangement in which the primary axis points toward the target at which sunlight is to be reflected. The secondary axis is perpendicular to the primary one. Heliostats controlled by light-sensors have used this orientation. A small arm carries sensors that control motors that turn the arm around the two axes, so it points toward the sun, incorporating a solar tracker. A simple mechanical arrangement bisects the angle between the primary axis, pointing to the target, and the arm, pointing to the sun. The mirror is mounted so its reflective surface is perpendicular to this bisector. This type of heliostat was used for daylighting prior to the availability of cheap computers, but after the initial availability of sensor control hardware. 041b061a72
