RETScreen database

A basic scheme of the configuration of the existing PV-diesel autonomous power system is presented in Figure 5.2. The main power components of this system are PV panels, diesel generating set, batteries and a converter. To simulate this system and perform a techno-economic analysis individual costs (capital cost, replacement cost, operation and maintenance cost) have to be identified for each component. The identification of these costs was mainly based on the RETScreen database developed in Canada (Natural Resources Canada, 1998). 

The configuration of the existing wind-diesel autonomous power system of Fair Isle is schematically presented in Figure 5.6. The main energy components of this system are a diesel engine generating set and two wind turbines. The identification of all kinds of costs for the main power components comprising Fair Isle s power system was also based on information derived from the RETScreen database (National Resources Canada, 1998). 

As for all case studies presented in this chapter, information on power component costs was drawn from RETScreen database (National Resources Canada, 1998). In more detail for photovoltaic panels a cost of 6750 /kW was used, resulting in a total acquisition cost of 67,500 . A capital cost of 450 /kW was used for the 35-kW diesel generator, which accounts in total for a cost of 15,750 . The total cost of the battery bank was considered equal to 17,600 . Finally, the total cost of the inverters installed in the system was 6700 . Lifetime, O M costs and power...
