Electricity is a resource that is used by unmanned spacecraft, lights, and instrumentation. It is stored using Batteries and is produced through an operating Rocket Engine, Solar Panels, or an RTG.
Contents
Electricity Consumption
Unmanned Satellite Cores use 1.7 e/m (electricity per minute)- Lights and Instrumentation use electricity as well. Also, Ion Engines require large amounts of electricity to operate.
Producing Electricity
Rocket engines
Many rocket engines produce plenty of electricity while running. However, they only do so while they run. Short burns every two minutes can be used to keep a probe alive, but don't forget doing so.
Solar panels
Solar Panels are a more automatic way to generate electrical energy. They need direct sunlight to work, so they won't work when you are on the night side of a planet you orbit.
All panels except for the OX-STAT Photovolatic panels need to be unpacked by right-clicking on them before they will generate energy. Unpacked solar panels are very flimsy and will disintegrate when experiencing atmospheric drag, so keep them retracted during liftoff, aerobreaking maneuvers or atmospheric re-entry.
Their energy output depends on their distance and orientation to the sun, but all solar panels except for the OX-STAT Photovolatic panels can orient themselves automatically to a certain degree.
They generate more electricity the closer to the Sun they are located. However, they do not currently use the inverse-square law. Rather, they follow a spline curve of 3 piecewise cubics defined from 4 points:
| Distance (m) | Power | Notes |
|---|---|---|
| 0 | 10x | |
| 13,599,840,256 | 1x | Kerbin's orbit |
| 68,773,560,320 | 0.5x | Jool's semi-major axis |
| 206,000,000,000 | 0x | Almost 3x Jool's orbit |
Radioisotope battery
The PB-NUK Radioisotope Thermoelectric Generator is a constant and reliable source of energy which doesn't require direct sunlight and is much more resistant to atmospheric drag than solar arrays. Unfortunately it has a very unpractical shape and as long as your craft hasn't got excessive energy use, solar panels can fulfill its needs with much less mass. Also, they don't look nearly as cool as solar panels.
Storing energy
A probe command pod can only store 5 units of energy which keeps it alive for not even 3 minutes. To survive longer without energy supply or to deal with peak loads (which often happen when using ion engines) batteries can be used to store more energy.
There is the circular Z-500 Rechargable Battery Bank with 500 units of energy designed to be used as a rocket segment and the Z-100 Rechargable Battery Bank with 100 units designed to be mounted on the outside of a vessel. The Z-100 have a twice as much charge per kg of mass, but are less elegant to place.
All energy storage available to a craft is fully loaded at launch.
