1: Does a Solar Panel produce full power?
BEBEST are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
A: 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...
2: How to test a solar panel?
A: 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.

3: How does temperature affect solar panel efficiency?
A: 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.
4: How to install our solar panels using different brackets?
A: 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.
5: Can I connect different solar panels together?
A: 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.
