There are two different types of tracking standalone solar power systems for residential solar energy units. Often there are alternate methods to mount a solar array. You could mount the solar panels on a fence, a flat wall, on a light pole, but the methods that follow are the most common.

1) The level, horizontal mounted array produces more energy in the summer when the sun is directly overhead.

2) Fixed angle at the optimum tilt angle yields the most kWh for a fixed array over the course of the entire year.

These two types of tracking systems create dramatically more exposure and higher sun hours all year long, but still more in the summer months. This relates to the overall need to calculate and take into account the total amount of energy required per month and per year then average out to the highest electric needs on a monthly basis. All of this data is included with the solar energy sizing estimates.
