Solar Panel Orientation

When we talk about solar energy, most people think of rooftop solar panels, generating clean electricity with just a little sunshine. But there's one crucial detail that's sometimes overlooked: the orientation and tilt of those panels.

These two factors can make a huge difference in the performance of your solar system. In fact, a poor orientation or tilt can cause you to lose up to more than 20% of the energy you could be generating. So, if you're thinking about installing solar panels, or are simply interested in understanding how this technology works, read on.

What is solar panel orientation?

Orientation refers to the direction in which solar panels are "facing." Here in Spain, in the Northern Hemisphere, panels ideally face south, as that's where the sun travels across the sky for most of the day. In the Southern Hemisphere, however, it's optimal to face north.

But this isn't a hard and fast rule. Depending on your energy usage (for example, if you use more energy in the morning or afternoon), an easterly or westerly orientation may be more convenient.

The Importance of Solar Panel Tilt

Tilt is the angle at which solar panels are mounted relative to the ground. This angle is key because it determines how much solar radiation falls directly on them. The optimal tilt varies depending on the location's latitude and the season, a figure our advisors can calculate for you.

Additionally, when dealing with a fixed system (which is most cases), small adjustments are sometimes made to maximize annual production.

What if the panels can't be oriented or tilted optimally?

Don't worry, all is not lost. Although the ideal is to optimize both factors, solar panels today are quite efficient, and even with a less-than-perfect orientation or tilt, they can generate a good amount of energy.

Furthermore, in addition to roofs with a specific pitch, there are installation options on freestanding structures if the roof is not suitable.

Conclusion

The orientation and inclination of solar panels are not minor details. They are decisions that can directly impact the efficiency, profitability, and return on investment of a solar system.

Therefore, when planning your installation, it is key to have a technical study that analyzes your location, your consumption, and the conditions of your home or business. This way, you can get the most out of the sun... and your investment!
