The OX-Stat-PD Photovoltaic Panel is a placeable solar panel. Its cost is significantly lower than that of the RTG but requires direct sunlight, so it will only work when on the day side of a planet.
Product description
“
The OX-Stat-PD Photovoltaic Panel can, when properly set up by trained engineers, power several ground-breaking science experiments at a time. Reduced power output caused by allowing Jebediah to just 'unfold the flippy bit' is not covered under the manufacturer's warranty. Needs a deployed central station to operate.

Power generated
The amount of power the solar panel generates depends on the engineer level of the Kerbal placing it.
It is independent of the distance to the sun.
