Site Selection and Positioning

Ideal site selection and positioning are essential to maximizing your solar panel system's efficiency and energy yield. Begin with a thorough shading analysis. Use tools like the Solar Pathfinder or Solmetric SunEye to identify potential obstructions such as trees, chimneys, or neighboring buildings. Even minor shading can greatly reduce your energy output, so aim for an obstruction-free zone, particularly between 9 a.m. and 3 p.m., when solar radiation peaks.

Next, evaluate your roof's durability. Make sure it's structurally sound to support the added weight of the panels and mounting hardware. Verify the roof's materials—metal or composite shingles are ideal, while wood or slate may require additional considerations. Inspect for existing wear and tear; a roof nearing the end of its life cycle should be replaced before installing panels.

Positioning is key. Orient your panels to face true south in the Northern Hemisphere or true north in the Southern Hemisphere for optimal sunlight exposure. The tilt angle should equal your latitude for year-round performance, but seasonal adjustments can yield a 5-10% increase in energy production.

Liberation from high energy costs starts with strategic site selection and precise positioning; get it right the first time.
