     in winter. Key methods include using adjustable rear leg braces (telescoping tubes), slotted rails for tilting, or pre-drilled holes in custom racking systems. Adjustments are typically made by loosening bolts, tilting to the desired angle found with a magnetic gauge, and retightening. 
    Key Adjustment Techniques 
    • Seasonal Angle Adjustment: Tilt panels closer to perpendicular to the sun to maximize production by 10–25%.
    • Structural Adjustments:
      • Telescoping Legs: Loosen hardware on adjustable rear legs to shorten for summer or extend for winter.
      • Pin/Hole Systems: Remove pins from pre-drilled holes and adjust to a new hole setting, often ranging from 10° to 60°.
      • Strut Channel Braces: Disconnect the rear diagonal strut, adjust the main pivot arm, and reconnect to a different spot.
    • DIY Considerations: Use pressure-treated lumber and unistrut to create pivot points, using hinges at the top of the rear legs and a variable-length connector at the base. 
    Optimal Tilt Angles 
    • Equinox (Spring/Fall): Set angle equal to your latitude.
    • Summer Solstice: Latitude minus

    What is the 20% rule for solar panels?
    The 20% rule means your solar panels should give you 20% more energy than your home usually needs. It is a way to avoid power loss during cloudy days or high-use months. For example, if your home uses 1,000 kilowatt-hours (kWh) of energy each month, you should install a system that gives you 1,200 kWh.Jun 27, 2025
