For most residential solar installations, the rooftop is the most common location for the system’s solar panels. This puts them out of the way so they don’t take up any usable space on your property, and allows them to blend into your home as much as possible. However, you don’t want an installer to just stick the panels up anywhere on your roof. It’s important that they be installed in the absolute best location possible to maximize solar energy production. How does an installer choose that perfect location? Keep reading to find out.
Orientation and Sun Exposure
Sunlight is the key to solar production. Installers use tools like solar pathfinders and digital software to analyze how sunlight travels across your roof throughout the day and the year. In the US, south-facing roofs typically offer the most consistent and powerful exposure to sunlight. However, east- or west-facing roofs can still be usable, especially when paired with the right tilt and inverter setup. So, in all likelihood, your installer will give preference to a south-facing roof slope, unless there are other unfavorable conditions on that slope.
When considering the optimal placement for solar panels, it’s crucial to evaluate the roof’s orientation and tilt to maximize energy efficiency. In Sacramento, where sunlight is abundant, positioning panels on a south-facing roof can significantly enhance solar energy capture. Consulting with local experts, such as North Valley Solar Power, can provide valuable insights into the best installation practices tailored to the specific climate and architectural nuances of the area. They can assess factors like shading from nearby trees or buildings, ensuring that your solar system operates at peak performance. By leveraging local expertise, homeowners can make informed decisions that align with both environmental and economic goals.
Roof Pitch and Angle
The angle or pitch of your roof affects how well panels can capture sunlight. A roof pitch between 15° and 40° is the ideal, but installers can use mounting equipment to adjust panel angles as needed. The goal is to align the panels to maximize exposure based on your latitude. If the angles of your roof slopes differ, the installer will likely favor whichever slope is between 15° and 40° to avoid extra costs for adjustable mounting equipment.
Potential Shading
Shade from chimneys, trees, vents, neighboring buildings, or dormers can significantly reduce the performance of your Solar Panels. Installers should always conduct a shading analysis, usually using drones or solar design software, to identify potential shading from objects like these. Panels are then placed in areas with the least amount of shading throughout the day to ensure consistent energy output.
Roof Space and Layout
Installers will inspect your roof’s usable space to determine how many panels can fit on each slope. Large, unobstructed sections of the roof are ideal for solar arrays. Complex roof shapes, skylights, or multiple elevations can cut down on the usable space on your roof, which influences panel layout and total system capacity.
The Bottom Line
So, when it comes to your panels’ location, installers will usually prioritize south-facing slopes with the correct pitch, and minimal shading. From there, they may also opt to use east- or west-facing slopes with similarly favorable conditions. By prioritizing locations that will produce the most solar energy, you can get the most out of each panel. So, when looking at Mission Solar panels for sale, be sure to consider where they will be installed for the best return on your investment.
