HOW TO DETERMINE THE IDEAL DIRECTION AND ANGLE FOR SOLAR PANELS?

1. IDEAL DIRECTION FOR SOLAR PANELS

Placing solar panels in the correct direction is a critical factor in terms of energy efficiency. The correct orientation of the panels ensures maximum utilization of sunlight.

• SOUTH DIRECTION: In countries in the northern hemisphere like Türkiye, the ideal direction angle for solar panels SOUTHBecause the Sun moves from the southern sky in the morning to noon hours and provides its most intense light to the south at noon. It allows solar panels to receive more sunlight and produce more energy.
• NORTH DIRECTION (REVERSE DIRECTION): On the contrary, the north direction is one of the least efficient directions for solar panels. It receives sunlight only in the morning and evening hours, which reduces efficiency.
• EAST AND WEST DIRECTIONS: If you want to benefit from sunlight all day long, EAST and WEST can also be installed in the directions. However, panels in these directions receive sunlight in the morning or evening hours, which means less energy production. These directions are suitable for users whose energy needs are concentrated in the morning or evening hours.

2. IDEAL ANGLE FOR SOLAR PANELS

The efficiency of solar panels is directly related not only to the orientation but also to their placement at the right angle. The angle ensures that sunlight hits the panel surface perpendicularly, allowing for more energy production.

• THE MOST IDEAL ANGLE (FOR Türkiye): The angle of the sun's rays in Türkiye varies annually. Therefore, the ideal angle may also vary depending on the season. However, in general, the angle at which solar panels will be placed BETWEEN 30° AND 35° This angle represents the most suitable angle range for the most efficient energy production in Türkiye.
• ANGLE ADJUSTMENT ACCORDING TO SEASON: If you want to get the most out of sunlight throughout the year, you can adjust the angle of the panel according to the seasons. In the winter months, the sun's rays hit at a more vertical angle, while in the summer months they hit more horizontally. Therefore, keeping the angle of the panel more vertical in the winter and more horizontal in the summer can increase efficiency.
• ROOF STRUCTURE AND AREA CONDITION: The roof slope and structure can also affect the angle of the solar panels. If the roof slope is too steep, it may be necessary to reduce the angle of the panels. Similarly, on flat roofs, the angle of the panels can be optimized using special mounting systems.

3. OTHER FACTORS IN PANEL LAYOUT

Apart from the direction and angle of solar panel placement, there are other factors to consider:

• SHADING: It is important that the area where the solar panels will be placed is not shaded by trees, buildings or other structures. Shading can seriously reduce the efficiency of solar panels. Therefore, the area where the panels will be placed should be selected to receive full sunlight.
• ROOF AREA AND LAYOUT: Since the roof is the main area where the panels will be placed, the condition of the roof should also be taken into consideration. Factors such as the slope, size, direction and placement on the roof directly affect the installation. If the roof area is limited, fewer panels can be placed, in which case it is important to choose more efficient panels.
• LOCAL CLIMATE CONDITIONS: Climate conditions affect how long and from what angles sunlight hits. For example, if you live in a cloudy area, you may need to take extra precautions to ensure your solar panels operate at full power.

4. TIPS FOR SOLAR SYSTEM EFFICIENCY

• OPTIMIZE SLOPE AND DIRECTION: If there is enough space on the roof, you can increase energy production in the morning and evening hours by placing the panels in different directions.
• USE MOUNTING SYSTEMS: Special mounting systems, especially for flat roofs, offer ideal solutions for adjusting the panel angle. These systems ensure that the panels are placed at the correct angle.
• SET UP MONITORING SYSTEMS: Monitoring the efficiency of solar energy systems allows you to detect potential problems early and can improve performance. The efficiency of solar panels is directly related to their correct orientation and angle. SOUTH DIRECTION AND ANGLE BETWEEN 30°-35°, provides the most efficient combination for solar energy systems in Türkiye. However, each situation may be different, so local conditions and roof structure should also be taken into account. With the correct installation of solar panels, it is possible to produce more energy, reduce energy costs and contribute to the environment.
