At Greenvolt Next, we specialize in maximizing the performance of solar energy installations for our clients. That’s why all our solutions are personalized and specifically focused on generating maximum energy savings. To achieve this, one of the most important studies conducted by our design team is how should solar panels be oriented for maximum efficiency. Let’s explain:

A relevant factor when installing solar panels in a company is their orientation, as this will determine their efficiency and productivity, which are key terms for achieving the highest performance.

Generally, the optimal orientation of photovoltaic solar panels depends on the geographical location and specific objectives. However, there are some general guidelines that are recommended to follow, which we detail below:

 

  • Orientation: The ideal arrangement for solar panels is facing south in the case of the northern hemisphere (azimuth angle = 180º), maximizing sun exposure throughout the day. This way, we ensure that they face the sun just when it’s offering its highest radiation for the longest part of the day, achieving a high level of performance.
  • Tilt: In general, the tilt of the panels should be equal to the latitude of the location plus an additional angle to maximize solar energy capture throughout the year. However, in certain cases, such as residential installations on roofs, panels may have a fixed tilt to fit the roof structure. In any case, our goal is to achieve maximum production at noon when the sun reaches its highest point on the horizon.
  • Location: This factor influences the determination of panel orientation and tilt. Depending on where the solar panels are installed, optimal angles, solstices, and positions will be determined. It’s crucial to avoid shading from trees, buildings, or other obstructions that could reduce the amount of sunlight they receive.

 

In addition to these three guidelines, it’s important to consider the variation in solar radiation across the earth, which can be calculated based on latitude and longitude on the map.

While these are general guidelines, the best orientation and tilt may vary depending on the specific location, local topography, and other factors. In any case, it will be the solar energy professional who provides the best specific advice for solar panel installation at your home or business.

Our goal at Greenvolt Next is to address the high demand for clean energy generation and support our clients throughout the entire value chain that’s part of the industrial self-consumption installation process. From the personalized design of the installation to the maintenance service offered by our after-sales division at your disposal.
