Summary
Solar Sails are consumable items required for the creation of dyson swarms. They are used in the EM-Rail Ejector to launch them into orbit around a star. The energy collected by Solar Sails can only be collected using a Ray Receiver.
Solar Sails have a limited lifespan of 1800s. This can be upgraded to up to 3600s by researching Solar Sail Life.
The energy generated by a solar sail depends on the star luminosity. Unlike real life, the energy generated does not depend on the distance to the star. Around a star with a luminosity of 1 a single Solar Sail generates 36 kW. While on the other hand, when they'are absorbed into a dyson sphere, every structure point gives you 96kw multiplied by luminosity, solar cells 10kw.
A single EM-Rail Ejector firing continuously can maintain a maximum of 600 Solar Sails in orbit with their default lifespan of 1800s. Around a star with a luminosity of 1 this will generate 21.6 MW.

Player Tips & Tricks
Since Solar Sails have a limited lifespan, the power production of a dyson swarm is dependent on the supply of new Solar Sails into orbit. If you stop producing or launching solar sails, the swarm's power generation will decrease as sails expire, until it reaches 0.
