1. What’s the difference between flexible solar panels and rigid solar panels?
Flexible solar panels and rigid solar panels have the same function of generating electricity from the sunlight but they come to the table a bit differently. Flexible solar panels are thin, light, and bendable (flexible), while rigid solar panels are encased in glass (and, most often, have a metal frame).
The lightweight and flexible solar panels are lightweight and thin, giving them a clear edge in the discussion of flexible solar panels vs. rigid. Heavy things are a nemesis for RVers – we like things that don’t increase the weight we’re carrying around. They can adjust to the contour of a curved roof or even to the front cap of a 5th wheel. They’re far more adaptable than rigid panels are.
2. Can I combine flexible and rigid solar panels?
Yes. As long as the specs match. If you have two different types of solar panels with the same voltage but different wattage, there is no problem with being wired in parallel.
3.What wattages does Renogy offer?
Renogy offers 50, 100, 175, and 200 watts flexible and lightweight solar panels to meet all your needs.
4. Can I walk on flexible solar panels?
We suggest not. Walking on solar panels will exert excessive pressure on a small area, it may cause cracks and damage to the panel.
5. Why are my solar panels underproducing?
The performance of a solar panel may be hindered for a number of reasons. Most commonly environmental conditions, such as indirect sunlight, temperature rise, cloudy sky, and dirt and stain build up on the top, which can lead to a lower efficiency
6. How can I connect solar panels to my electrical circuit (series vs parallel)?
Solar panels can be connected in series or in parallel to meet your electrical circuit size and power demands.
In series: the operating voltage output adds up, while the system current output is the same as that of one panel.
In parallel: the operating current output will add up, while the system voltage output will be the same as the output of one solar panel.
To achieve optimum power output and system rating for your power system, you can use both parallel and series connections.
7. How many solar panels do I need?
The best way to gauge how many solar panels you need is to understand the power load needed for your system.
Power is measured in watts, and the capacity is commonly measured in Watt-hours (multiplying power output in watts by the required number of hours of operation multiplied by a safety factor of 1.5-2). Therefore, it is wise to size your battery bank first based on the minimum required capacity, and then accordingly, decide how much input power and how many panels are needed.
8. Will this panel produce power in overcast conditions?
Yes, it will. Made of high-quality materials, this Renogy solar panel still works during cloudy weather conditions. But please note that the power conversion is not as high as on sunny days.

9. Do solar panels require maintenance? Can I wash my solar panels?
Generally, solar panels require maintenance because if a lot of dirt or stain piles up on top or in corners, the conversion of sunlight will be affected, resulting in lower efficiency. As for how to clean solar panels, you can use a microfiber cloth, glass cleaner, and water.
