Building Space Based Solar Panels

For both uses a key figure of merit of the solar panels is the specific power watts generated divided by solar array mass which indicates on a relative basis how much.

Building space based solar panels.

Solar panels on spacecraft supply power for two main uses. Mankins and others estimate the total cost for developing building launching and assembling all the components of a space based solar power plant is on the order of 4 to 5 billion a fraction. The concept of space based solar power is not new. In 1999 nasa initiated a 22 million study investigating the feasibility of space based solar power.

The two most commonly discussed designs for sbsp are a large deeper space microwave transmitting satellite and a smaller nearer laser transmitting. Power for spacecraft propulsion electric propulsion sometimes called solar electric propulsion. Space based solar power sbsp is the concept of collecting solar power in outer space and distributing it to earth potential advantages of collecting solar energy in space include a higher collection rate and a longer collection period due to the lack of a diffusing atmosphere and the possibility of placing a solar collector in an orbiting location where there is no night. It is hard to imagine accomplishing a factor of 100 reduction in launch costs.

In fact this technology was mentioned way back in 1941 in the science fiction story reason written by isaac asimov. Apart from providing around the clock power on demand beamed from space the new solar cells panels and production processes being developed through the program could revolutionize space based. Power to run the sensors active heating cooling and telemetry. These panels convert solar power into either a microwave or a laser and beam uninterrupted power down to earth.

Space based solar power attracted considerable attention in the 1970s as the necessary individual technical components in essence photovoltaic cells satellite technology and wireless power. On earth power receiving stations collect the beam and add it to the electric grid. China is planning to build the world s first solar power station in space to provide inexhaustible clean energy according to a story in science and technology daily the official newspaper of.
