As now the electricity production is the only purpose: they consume 0.0025 units of fuel for each electric charge unit (0,0025 /⚡), means they produce 400 units of electricity from a single unit of fuel. The fuel cell, like the Fuel Cell and Fuel Cell Array, converts liquid fuel and oxidizer directly into electric charge, similarly to generators. Unfortunately, it has a very impractical shape and is significantly heavier than solar panels with a comparable output of electricity.

The PB-NUK Radioisotope Thermoelectric Generator is a constant and reliable source of energy that doesn't require any sunlight and is much more resistant to atmospheric drag than solar arrays. Generated power will also decrease with increasing distance from Kerbol, following the real-life inverse-square law: Reorienting a vessel to manually aim the panels at the sun and eliminate shadows cast on them will also improve power generation. Except for the surface-mounted OX-STAT Photovoltaic Panels (and its larger brother OX-STAT-XL Photovoltaic Panels, all panels will automatically pivot around one axis to face the sun as much as possible. The energy output of solar panels depends on their orientation to Kerbol.

Note that, as of version 1.0, the unshielded OX-4 series solar panels can't be retracted once deployed, so they are not suited for aerobraking missions. Unpacked solar panels are very fragile and will easily break off when colliding or experiencing atmospheric drag, so they must be retracted during liftoff, aerobraking, or atmospheric re-entry. Due to this unreliability, it is recommended to have some energy storage as a buffer when supplying a craft solely with solar panels.Īll panels, except for the OX-STAT Photovoltaic Panels and the OX-STAT-XL Photovoltaic Panels, need to be extended using the right-click menu ( Extend Panels option, and for the retraction choose the Retract Panels) or action groups (using the Toggle Panels command, the player can extend and retract several solar panels with a single keystroke) before they will generate energy. However, they need direct sunlight to work, so they won't produce electricity on the night side of a planet, in the shadow of a spacecraft or during eclipses of the sun, although the craft is illuminated while in an eclipse. Solar panels are a lightweight source of electrical energy. Jet engines only generate electricity when supplied with intake air.

The adjacent table shows the engines which provide electricity, their production at full throttle and fuel usage in vacuum. The exact output varies based on the throttle level, and engines not running will not produce any electricity. Many rocket and jet engines have alternators installed which produce electricity.
