Once you own a parcel of land on the sun, you just can turn off the spotlights which foundations stand on that parcel. That way, you not only protect the ozone layer, but you save energy on the sun as well.
The powerplants which feed the spotlights on the sun can only produce about 40 billion MegaKelvin of energy. The famous german scientist Bärlach calculated that the sun will stop to shine in about 80 years from now. This time can be stretched to about 130 years by turning off 40% of the floodlights on the sun.
