Powering Health

Electrification Options for Developing Country Health Facilities

Example Laboratory Infrastructure Load Calculations for Developing Countries

Use the load calculation tool to perform your load analysis.

Before any on-site energy solution can be developed for a health facility laboratory a load analysis needs to be completed based on the specific equipment and usage patterns for that facility. These examples provide load calculations for some different sized facilities visited in Haiti and Zambia.

Table 1.
This table demonstrates the number of hours of operation which can be achieved with a battery inverter set-up for the different sized labs given the stated number of batteries (Trojan T-105 are used for this example).
