The array s tilt is the angle in degrees from horizontal.
Solar panel efficiency vs angle of incidence.
A flat roof has a 0 degree tilt and a vertical wall mount has a 90 degree tilt angle.
Let s start with two key terms.
The angle of the sun varies throughout the year as illustrated in figure 9.

While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face.
Elevation angle and azimuth angle commonly shortened to angle and azimuth for brevity.
The panel will collect solar radiation most efficiently when the sun s rays are perpendicular to the panel s surface.
If it s standing upright perpendicular to the ground it is at a 90 angle.
Today we re going to explain how to mount your solar panels to get the most energy from them.
A critical parameter for installing fixed tilt panels is the tilt angle since pv panel output increases with increasing exposure.
Solar panels are most efficient when pointing at the sun so engineers want to minimize this angle at all times.
For the best results solar panels should be oriented towards the south.
Orientation of the panels.
Solar panel angle is another way of describing the vertical tilt of your pv system.

This is the angle between the line that points to the sun and the angle that points straight out of a pv panel also called the line that is normal to the surface of the panel.
Optimum angle differs during winter months.
This is the most important angle.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
For example if you are seeking to maximise solar generation during winter months be it for an off grid system or higher energy consumption levels you would ideally want to angle your panels at a greater tilt for maximum exposure to the low winter sun.
The solar panel angle can affect the amount of solar electricity you generate and is based on two factors.
Orienting the pv panel in a direction and tilt to maximize its exposure to direct sunlight will optimize the collection efficiency.
The ideal angle for your solar panels can vary depending on your solar objectives.

Welcome to another entry in our ongoing solar 101 series.
Whether you are installing a solar panel on a flat roof or a pitched roof the output of the solar pv system would be increased by optimizing the tilt angle.
