Most satellites use [[Solar panels on spacecraft|solar panels]] to generate power, and a few in deep space with limited sunlight use [[radioisotope thermoelectric generator]]s. [[Slip ring]]s attach solar panels to the satellite; the slip rings can rotate to be perpendicular with the sunlight and generate the most power. All satellites with a solar panel must also have [[Batteries in space|batteries]], because sunlight is blocked inside the launch vehicle and at night. The most common types of batteries for satellites are [[Lithium-ion battery|lithium-ion]], and in the past [[Nickel-hydrogen batteries|nickel–hydrogen]].<ref name=":0" />{{Rp|pages=88–89}}
