Solar Energy, Complementary Energy

Solar Energy, Complementary Energy
Solar energy is not a mainstream energy, like thermal power, hydro power etc. solar energy, from my personal point of view, is absolutely a complementary energy. My view and arguments are as as below 2 points:
1. High price. Although there are much of price dropping on solar equipment thanks to technology innovation, large-scale production, and entrepreneur’s precision Management. After the past 10 years, the cost of equipment going down sharply, module from 4 USD/W to 0.6USD/W. but it’s hard to go down. The price will be near the floor. I guess, 0.4USD/W. Actually now the solar power price are still higher than traditional energy. Price is the key issue for solar energy to become mainstream energy. 
2. Land acquisition. Solar panel need much land to lay out. But the more energy the city need, the less land we can get for solar panel installation. And the long distance energy transmission will increase the cost either for desert solar project.
So we must realize the solar energy is only complementary energy, which can’t instead of traditional energy. Solar energy have its own territorial dominance, for example roof-top projects to add more energy for city, and off-grid system to power the remote rural area, and solar products to satisfy human basic power requirement on poor area, and solar portable system for convenience of daily life.
Don’t build too much of big solar plants, let’s make full use of authentic function of solar energy to serve human being.
