This inefficiency eventually reduces the system’s lifespan and raises operating expenses.
How to Avoid It:
- Determine the Correct Orientation:
- To get the most sunshine exposure in the northern hemisphere, panels should face south.
- It is recommended that panels in the southern hemisphere face north.
- Depending on particular solar patterns, minor modifications to the east or west may maximize performance for sites close to the equator.
- Optimize the Tilt Angle:
- For year-round effectiveness, modify the tilt angle to correspond with the location’s latitude. For instance, the tilt angle of the panel should be around 30° if the latitude is 30°.
- Utilize movable mounts that enable seasonal adjustment to optimize energy absorption during winter when sunlight levels are lower.
- Take Weather Conditions into Account:
- To avoid snow accumulation in regions with high snowfall, think about using a greater tilt angle.
- Make sure the mounting mechanism and angle can tolerate environmental stresses in areas with high wind speeds.
- Utilize Software for Solar Simulation:
- Installers can tweak their solar energy systems before installation by using tools like PVsyst or HelioScope, which can predict the ideal orientation and tilt angle based on site-specific data.
- Regular Inspections:
