6 Frequently Asked Questions about “Solar cell array considerations”
How does a solar array affect a spacecraft?
Without careful design of the solar cell layout and electrical wiring, the solar array current will generate a magnetic dipole moment. The magnetic moment exerts a torque on the spacecraft relative to Earth's magnetic field and is a disturbance to the spacecraft attitude control system.
What factors are considered in solar array design?
These include power conversion efficiencies (solar array regulation, power distribution regulation and power transmission outside of the solar array itself) and how well the power from the solar array can be controlled. These are part of power electronics and are not considered in this section, yet are factors in solar array design.
What is a solar cell array?
The Solar Cell Array The array is composed of solar modules connected according to certain configuration to satisfy the voltage, the current, and the power requirement. If the array voltage is Va, the array current is Ia, and the array power is Pa, one can determine the number of the modules required and their circuit configuration.
What makes a solar array safe?
Solar arrays include motors, hinges, and various other devices to deploy and support the solar array. These are typically inherent to a specific design and cannot be generalized. Another factor is retraction and redeployment. It is preferred for safety to deploy the solar arrays once.
Are solar cells based on a datasheet adequate?
Here, they illustrate that merely using the solar cell properties from the datasheet is inadequate. Rather, careful analysis of temperature, radiation and many other factors will provide a robust, properly sized solar array design. Note that some factors are not included in this list.
Why do we need solar arrays?
Due to solar array's excellent power per unit mass, they have the potential to be deployed in large numbers to attain very high power levels to enable a variety of lunar base activities, particularly for production level In Situ Resource Utilization (ISRU).
