Installing a solar panel on the sun is easier said than done. The closest real example is probably the Parker Solar Probe: www.youtube.com/watch?v=pOZhPz92Dic
That number didn’t really seem enough to me. However, the solar luminosity is about 3.8×10^26 watts and the surface area about 6.1×10^18 m2, ie. 62.3 MW / m2. 8760 hours in a year times 62300 kW equals 545 million kW/h, at twenty percent efficiency times twenty cents each is $21.8 M/a.
The sun might seem to be really, really hot; but in fact, it is just quite hot and really, really big.
The corona is indeed super hot, but also quite tenuous in comparison to the rest of the sun. The photosphere is only about 5500 °C. If our solar panels were made of diamond they would have melted at 3500, but it’s not impossible to imagine a solar panel that could be positioned ‘quite’ close to the sun’s surface - would just need to be made from some quite fancy materials.
They could send the energy wirelessly in the form of light beams, then use special panels to transform those beams of light on Earth. Let's call them "solar panels".
