Estimate the ideal spacing between rows of solar panels to minimize shading and maximize efficiency based on latitude, tilt, and panel height. Formula: Spacing = Height / tan (Solar Altitude).
If your roof isn't at the right angle, doesn't face south, or has obstructions like chimneys or skylights, your solar panels won't generate maximum electricity.
Once you've identified damaged cables, you need to address the issue promptly. Here's how: Always turn off your PV system before beginning any repair work.
Your inverter does not appear to supply it (smaller inverter-only units often don't). You will probably measure significant AC voltage between G and N at the inverter.
