Factors that affect the efficiency of PV and hot water units include shading, tilt angle, and your electric load and usage. We place the system in the optimal sun location for you. Using the Solmetric SunEye, we can determine the possible shading effects for anytime of the year. Shading obstacles to consider vary from trees and buildings to satellite dishes and chimneys. The tilt angle refers to the tilt of the solar panels facing the sun. Typically, the best tilt angle is your latitude; however, systems with panels in rows and columns may be tilted at a lower angle to reduce wind loading.
The best way for owners to maximize their energy system is to make their homes more energy efficient. Buying energy efficient appliances and moderating heat and air condition can greatly reduce energy consumption.
