In most cases, it is normal for a solar panel to not be able to provide its full nominal power. Factors affecting the performance of solar panels: peak sun hours, sunlight angle, operating temperature, installation angle, panel shading, adjacent buildings etc.

The ideal conditions: Test in the noon, under a clear sky, panels should be at 25 degrees tilted towards the sun, and the battery is at a low state/less than 40% SOC. Disconnect the solar panel from any other loads, using a multimeter to test the panel’s current and voltage.

Solar panels are generally tested at about 77°F/25°C and are rated to perform at peak efficiency between 59°F/15°C and 95°F/35°C. Temperature going up or down will change the efficiency of the panels. For example, if the temperature coefficient of power is -0.5%, then the panel maximum power will be reduced by 0.5% for every 50°F/10°C rise.

There are mounting holes on the panel frame for easy installation using a variety of brackets. Most compatible with Newpowa’s Z-mount, tilt-adjustable mount, and pole/wall mount, making panel mounting suitable for a variety of applications.

Though mixing different solar panels is not recommended, the mismatch can be achievable as long as each panel’s electrical parameters (voltage, current, wattage) are carefully considered.
