Solar Panel Efficiency Vs Sun Angle

A fixed tilt panel is angled to receive the maximum.

Solar panel efficiency vs sun angle.

Today we re going to explain how to mount your solar panels to get the most energy from them. It is more convenient and less expensive to install. 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. 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.

The sun moves across the sky and will be low or high depending on the time of the day and the season. A fixed tilt solar panel is the most common type. This is because the sun is always in the southern half of the sky in the northern hemisphere. If it s standing upright perpendicular to the ground it is at a 90 angle.

The angle between a photovoltaic pv panel and the sun affects the efficiency of the panel. Let s start with two key terms. The tilt angle has the biggest effect on the efficiency of the solar panel. That is indeed the best angle at noon on that day but it does not take into account the best angle for capturing solar energy at other times of the day.

The panel will collect solar radiation most efficiently when the sun s rays are perpendicular to the panel s surface. Welcome to another entry in our ongoing solar 101 series. Solar panels give the highest energy output when they are directly facing the sun. When a solar system is level with the ground it has no tilt.

The solar panel angle can affect the amount of solar electricity you generate and is based on two factors. Solar angles tracking systems. 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.

The vertical tilt of your panels. Orientation of the panels. The solar panel angle of your solar system is different depending on which part of the world you are. Optimum angle differs during winter months.

That is why many solar angles are used in pv power calculations and solar tracking systems improve the efficiency of pv panels by following the sun through the sky. For the best results solar panels should be oriented towards the south. Orienting the pv panel in a direction and tilt to maximize its exposure to direct sunlight will optimize the collection efficiency. When the angle of the sun is perpendicular to the solar panel it provides the maximum energy output.
