Rugged Aluminum Frame

Corrosion-resistant aluminum frame design with sturdy corner supports, ensures that it endures the outdoors for an extended period of time without damage or loss of performance.

High Transparency

The anti-reflective low iron-tempered glass enables up to 91.5% high transparency, allowing direct sunlight to be converted to more electricity. Also, this glass is rugged enough to resist external impact.

Pre-Drilled Holes for Easy Installation

Comes with pre-drilled holes, including ground mounting holes for fast and convenient installation. Compatible with Renogy Z Brackets, Corner Brackets, Pole Mounts and Tilt Mounts.

IP68 Junction Box

Provides complete IP68 (1 meter depth in water for 1 hour) protection against environmental particles such as dust and low-pressure water jets.

IP67 Solar Connectors

No need to worry about bad weather. These IP67 waterproof solar connectors ensure that the water and dust will not enter the connector during extended outdoor use. Effectively preventing water from seeping in. Perfect for your yacht and marine applications.

Efficient Performance

Bypass diodes protect the solar cells from overheating and allow the solar panel to continue working during accidental shading by bypassing the underperforming cells.

FAQs — Renogy 320 Watt Monocrystalline Solar Panel 4 Pieces (RNG-320Dx4-US)

Q: Is each panel 320W or a whole combination? What about the size and weight?

Answer: 320W per panel. The dimension of one panel is 65.6 x 39.4 x 1.4 inches and the weight is 39.7 lbs. Currently, we have 4-pack, 6-pack, 8-pack, and 10-pack available.

Q: Can I use this panel for the roof of an RV?

Answer: Yes, you can, as long as the roof of your RV has enough space to install it. Please confirm the size: 65.6 x 39.4 x 1.4 inches. In addition, this 320W solar panel is also ideal for residential and commercial rooftop systems, solar power plants, and more. It's suitable for roof mounting and ground mounting.

Q: Can these panels be used on a grid tied system?

Answer: Sure, they can. These 320W solar panels work with on-grid, off-grid, and hybrid systems. But please note that when using them on on-grid and hybrid systems, we recommend that you contact a licensed solar installer who is familiar with on-grid/hybrid setups. On-Grid solar system means solar power equipment (array or solar panel) is connected to the utility grid, while Off-Grid refers to a system that is not connected to the grid. An Off-Grid system is not affected by grid blackouts. A Hybrid system is when your solar panels remain connected to the grid's power lines and have a backup battery system to store excess power.

Q: How many kWh a day do this solar panel produce?

Answer: If your solar panels are exposed to 5 hours of direct sunlight per day, it can provide an average of 1280-1600 Watt-hours (1.28 kWh-1.6 kWh) of electricity (depending on sun availability).

Q: Do these panels have pre-drilled holes on the back?

Answer: Yes, they have. The pre-drilled holes help you to install the solar panel fast and secure.

Q: Are there any brackets for the panels to be attached to the roof?

Answer: There is no mounting bracket included in the packaging list. BUT you can find Tilt Mount Brackets, Flat Roof Tilt Mounts, and Z Brackets from the Renogy official store to meet your needs.

Q: Why are my solar panels underproducing?

Answer: The performance of a solar panel is influenced by a number of factors. The most common environmental conditions - indirect sunlight, temperature rise, cloudy sky, dirt, and stain build up on the top low iron-tempered glass - will lead to a reduced power output. Moreover, the conversion efficiency of a solar panel may decrease over time. Renogy guarantees a five-year/95% efficiency rate, a ten-year/90% efficiency rate, and a 25-year/80% efficiency rate for all solar panels.

Q: Are all the wires included in the solar panel package for connecting it to my battery?

Answer: The solar panel only contains a built-in MC4 lead (female and male connectors). No extra cables are included for connecting to your battery. You'll need to get an additional charge controller, adapter kits, and tray cables. If you need any of these installation accessories, please visit Renogy's official website store to purchase them.

Q: Can this solar panel be adapted to a 12V Marine Battery or 48V Lithium Battery?

Answer: Yes, it can. The open circuit voltage of this 320W solar panel is 40.1V. So it's suitable to use for charging your 12V Marine Battery and 48V Lithium Battery (by connecting at least two solar panels in series). You need to connect the solar panel(s) to a Charge Controller supporting a 12V or 48V system.

Q: Can I connect these to a different brand of panels? The ones I have are also 320 watt, just different brand.

Answer: We suggest you use a solar panel from a different brand with the same Open Circuit Voltage as this Renogy solar panel to ensure a high power output.

Q: What's the main feature of the black aluminum frame?

Answer: The black aluminum frame adds an enhanced anti-corrosion coating, allowing the panel to be used outdoors to withstand harsh environments, such as extreme heat, heavy rain, and more.
