Satellites are usually fitted with a re-chargeable battery, and solar panels. The solar panels absorb energy from the sun, and the batteries store the energy for use by the satellite.
how to work HPA
The eclipse effect in satellite communication occurs when the satellite passes into the shadow of the Earth, causing a temporary loss of communication signal. This happens during solar eclipses or when the satellite is behind the Earth in its orbit. To mitigate the impact, satellite operators can use battery power or pointing strategies to maintain connectivity during these periods.

wastage of power
Because of economics. On the ground you an afford to use a big transmitter and a big antenna, while on the satellite both have to be smaller. Therefore most of the power and the gain happens at the ground station.
To build a satellite, you need to first define its purpose and specifications. Then, design the satellite components, such as structure, power systems, communication systems, and payloads. Finally, assemble the components, test the satellite thoroughly, and launch it into orbit.

The Traveling Wave Tube Amplifier (TWTA) is widely used as a power amplifier in satellite communication systems. It amplifies signals in the microwave frequency range and is capable of providing high power output with low noise and distortion. TWTA technology has been utilized for several decades in satellite communication due to its reliable performance and efficiency.
