Practical Application

1. Implement ECMs to reduce electricity demand before selecting or sizing a PV system.
   
   • Review the energy audit report and implement recommended no- and low-cost savings measures.
   • Consider implementing other strategies in this chapter before PV (see Energy: Re-/Retro-Commissioning, Electrical Demand Management, Automatic Lighting Controls, Lighting Equipment and Lamps, and Computers and Office Equipment).
2. Consult local solar developers for feasibility of solar power.
3. Determine appropriate locations for PV modules.
4. Determine life-cycle cost, design, installation, and Cx of the PV system.
5. Develop a written system maintenance plan for facility operators to use. Identify cleaning and testing procedures and frequency, as well as resources for future repair and replacement.
