The energy which is produced by solar panels you can sell only in the daytime. They have very low productivity and so during the night you will take out more energy than the sell day.
Well you are right about solar energy, but solar is not the only way to produce electric energy. There are other safe ways of producing energy, while not damaging the nature and planet it self. More and more people are using wind, water and natural things for producing energy, and that is really great, because they get electricity and they do not damage nature. 
The Gemasolar plant is owned by Terrsol Energy, a joint venture between the Spanish construction company SENER and Masdar the futuristic zero emission UAE city
This plant deploying the molten salt CSP technology achieved an important landmark, that of 24 hours uninterrupted power production for a full month. This was achieved in June 2011, just a month after the commissioning of the plant.
