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. 50W Solar Panel 100W Solar Panel 220W Solar Panel 100W KIT Solar Panel 200W KIT Solar Panel See Details See Details Add to Cart See Details See Details Customer Reviews 4.4 out of 5 stars 272 4.4 out of 5 stars 272 4.4 out of 5 stars 272 4.4 out of 5 stars 272 4.4 out of 5 stars 272 Price — — $212.49$212.49 — — Dimensions (in.) 15.75*28.54*1.18 33.07*26.38*1.18 56.69*30.12*1.38 36.61*23.03*1.18 36.61*23.03*1.18 UZ Bracket UV Bracket 55inch Solar Panel Bracket 2 to 1 parallel connector 15FT Extension Cable See Details Add to Cart Add to Cart Add to Cart Add to Cart Customer Reviews 5.0 out of 5 stars 2 4.0 out of 5 stars 1 5.0 out of 5 stars 4 4.5 out of 5 stars 27 4.5 out of 5 stars 27 Price — $28.99$28.99 $119.99$119.99 $12.99$12.99 $18.99$18.99 Solar Charge System Accessories Solar Panel Z Brackets Solar Panel UV Brackets Solar Panel 410P Brackets IP67 Waterproof 15FT 10AWG extension cable with male/female connectors
