Product Description
Compared to a regular 12V panel, the Newpowa 250W 15V solar panel, offers several advantages, including extended operational hours in the morning and evening, enhanced performance on cloudy days, and improved compatibility with MPPT controllers. You can also connect two 15V panels in series allowing them to operate efficiently in a 24V system. These benefits make 15V panels an excellent choice for off-grid solar applications where reliability, efficiency, and versatility are paramount.
Easy Installation
The panel comes with four easy mounting holes with a diameter of 9x 14mm, and two grounding holes with a diameter of 5mmWith a pre-attached 3ft solar connector, the panel can be quickly connected to other itemsCompatible with Newpowa z-bracket, tilt adjustable mount, and pole/wall bracket, the panel can be installed for various applications
Versatile
Supported by a wide range of mounting options including flat surface, pole and wall installationCommon applications includes RV, camper, SUV, marine, residential rooftop, remote farm, disaster relief, traffic signs, etc.
High-efficiency
Uses high-performance Mono cells encapsulated in EVA (ethylene-vinyl-acetate)Pre-installed bypass diodes inside junction box that minimize power drops caused by shading

FAQ
1: Does a Solar Panel produce full power?
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.
