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.
Solar panel efficiency vs angle of incidence.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
Global solar photovoltaic pv installations on rooftops and in power plants are growing rapidly and will grow further as the world transitions from fossil fuels to clean renewable energy jacobson et al 2017.
Welcome to another entry in our ongoing solar 101 series.
Elevation angle and azimuth angle commonly shortened to angle and azimuth for brevity.
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.
If it s standing upright perpendicular to the ground it is at a 90 angle.
Let s start with two key terms.
When a solar system is level with the ground it has no tilt.
Orientation of the panels.
The array s tilt is the angle in degrees from horizontal.
The panel will collect solar radiation most efficiently when the sun s rays are perpendicular to the panel s surface.
The solar panel angle can affect the amount of solar electricity you generate and is based on two factors.

This is the most important angle.
The vertical tilt of your panels.
Optimum angle differs during winter months.
Orienting the pv panel in a direction and tilt to maximize its exposure to direct sunlight will optimize the collection efficiency.
Solar panel angle is another way of describing the vertical tilt of your pv system.
Solar panels are most efficient when pointing at the sun so engineers want to minimize this angle at all times.
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.
For the best results solar panels should be oriented towards the south.
The ideal angle for your solar panels can vary depending on your solar objectives.
The angle of the sun varies throughout the year as illustrated in figure 9.
Today we re going to explain how to mount your solar panels to get the most energy from them.
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.
