Factors Affecting Solar Panel Performance: - Peak Sun Hours - Sunlight Angle - Operating Temperature - Installation Angle - Panel Shading - Adjacent Buildings

Testing Solar Panels: - Test in the noon under a clear sky - Panels should be at 25 degrees tilted towards the sun - Battery should be at a low state (less than 40% SOC) - Disconnect the panel from any other loads and use a multimeter to test current and voltage

Temperature Impact on Solar Efficiency: - Solar panels are tested at 77°F/25°C and perform best between 59°F/15°C and 95°F/35°C - For every 50°F/10°C rise in temperature, the panel's maximum power is reduced by 0.5% due to the temperature coefficient of power.

Mixing Solar Panels: - Mixing different solar panels is not recommended, but can be achieved if the electrical parameters (voltage, current, wattage) of each panel are carefully considered.
