Some of the product data requirements for the model are provided in the RETScreen Product Database. To access the product database specific to the type of system being considered, the user should click on the "blue-underlined" hyperlink next to the entry cell that says "see product database" or "see PDB." The product database provides information on the equipment associated with the project. From the product database dialogue box the user may obtain product specification and performance data, as well as manufacturer contact information.

From the Product database dialogue box the user selects, for example, the Manufacturer, Model and the number of units. The data can be pasted from the dialogue box to the spreadsheets by clicking on the "Paste Data" button. Data entered using the product database may be overwritten; i.e. the user may prefer to use other data and can manually enter values into the cells. The product database contains a link to the Websites of the product manufacturers. In the case where the Website link cannot be activated the user should try using another browser.

Note that the capacity provided in the product database for some technologies (e.g. reciprocating engines) is an indication only and needs to be verified with the manufacturer for each specific application. Reciprocating engines, for example, are rated for ISO conditions (15°C, 101.3 kPa and 60% relative humidity) and for specific fuels; therefore, the type of fuel used and the site conditions, such as humidity, temperature and altitude will have an effect on the actual capacity. Also, an engine can run at a higher output then rated capacity, but it will have a shorter lifespan and will require more maintenance. For shorter projects, a higher capacity can be entered in the model since the rated capacity typically includes a derating factor.

Note: To see all the manufacturers listed in the product database and their contact information, the user can open the product database using the icon « i » in the RETScreen menu bar or toolbar.
