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.

Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonCustomers say
Customers like the power, ease of installation, value, quality and size of the solar panel. For example, they mention it delivers the power they need, it's easy to mount and the connections are easy. That said, some appreciate the size and performance.

People need to learn about how these work before they post bad reviews. All panels have a rated wattage output. Example: A 100w panel simply means it can have a 100w DC output under "Optimal" conditions.
This includes unobstructed sunlight/proper angle alignment/power drop in cabling-etc. And the time these panels are in that perfect zone is maybe 5 hours a day. And remember, panels will pull only how much is needed. If your battery is charged and you're only using 150w factoring in inverter efficiency, don't expect panel to pull more wattage than is needed unless you are grid tied...it just doesn't work that way. I get 500-550w on any normal day with 3 of these 210w panels ,Off-Grid and very pleased with that performance. it recharges my 200AH Lifep0 battery from the night before and powers a basic home office at the same time. No issues.

No issues.
Panels are very well packaged and no sign of external damage to the boxes. Now have every thing I need to really try these panels. I have finally received 50 feet of 8 and 10 Ga. wire with MC4 connectors and have two Bluetti EP 240 solar generators. Should charge fairly quickly at over 1000 watts of available power. Bought two Bluetti EP240's. Over a year old, very happy with these units. After 6 months in storage (initial full charge with wall outlet) these units are still fully charged. Need two (charge one while the other is running 12v frig and freezer (ICECO units) and LG portable AC unit. LG and ICECO units are top quality pieces of equipment. Placed both ICECO units on 36" SS shelving on wheels. Easy to work with and roll around when needed.
I was getting 425 watts from the two panels on a mid February sunny day. This will more than suit my needs, and should charge my power station from 0-100% in 3-4 hours.
This may not be the best value per watt in ratio to the price of the panels, but I am in need of something to recharge my power station in a short period of time while hunting off grid. These panels will do the trick!
