A new solar panel designed & manufactured by Nanosolar is coming to market! These high output solar panels will be able to produce energy at a cost of about 5 - 6 c/KW/H, which is almost as cheap as energy from fossil fuel plants.
Once solar enegy prices cross this important inflection point, prepare for radical changes in the energy market place. Radical changes can be significantly disruptive at multiple levels. Consider for instance, that low cost solar creates new options for vehicle travel and lowers the threshhold for decentralised power production.
