14/10/2018Cost Reduction: Is this possible?
14/10/2018The accelerating pace of changeLevelized cost of energy at a couple of the preeminent utility-scale solar sitesaround the world is going below 3 /kWh the SunShot 2030 cost goal October 2017: Saudi Arabia’s 300 MW PV plant was bid at 1.79 /kWh September 2016: Abu Dhabi Electricity and Water Authority’s 350 MWPV plant accepted a bid from JinkoSolar–Marubeni at 2.42 /kWhenergy.gov/solar-office7
14/10/2018Innovative packaging material for improvedenergy yield Up to 10 C temperature difference Reduced thermal losses ( 1%) Improved reliability expected8

14/10/2018Added value PV deploymentsPV modules that produce energy AND provide another value, such as Protect building from elements (Roof, windows, façades) Reduce evaporation on reservoirs (Floating PV) Allow more varied crops to be grown Reduce fuel needs (remote grids, solar cars, ships)Value is more than energy Appearance, weight, physical properties are all important.Source: J.
