Renogy Bifacial 320 Watt /400 Watt Monocrystalline Solar Panel
- 【Bifacial Solar Panel】 Transparent mesh backsheet material and double-sided cells are used to realize double-sided power generation of solar panels. The solar panel back can provide an additional 5-30% of nominal power generation, bringing you more power generation benefits!
- 【Built to Last】 Corrosion-resistant aluminum frame provides extended outdoor use that ensures the panel can last for decades. Sturdy construction, designed to withstand wind loads of 2400Pa, and snow loads of 5400Pa. The IP68 rated junction box is versatile due to its ability to withstand dirt, dust, debris, and low-pressure water jets.
- 【16BB for Higher Conversion Efficiency & Longer Lifespan】 Renogy's new high-efficiency module series utilizes advanced 16BB cell technology, which effectively improves the module's photoelectric conversion efficiency; at the same time, it reduces the impact of hot spots and hidden cracks, resulting in a longer service life and more efficient module performance.
- 【Enhanced Performance in High Temperatures】 The solar panels are characterized by a low temperature coefficient, which means that Renogy's new high-efficiency modules have a much lower power loss than ordinary modules in high-temperature environments, giving them a much better product performance. This enables customers to generate more power even in the summer months or in extremely hot areas.
- 【10-Year Warranty】 This solar panel comes with an excellent 10-year materials and workmanship warranty and a 25-year 80% output warranty.
- 【Positive Power Tolerance, More Reliable Energy Output】 Our solar panels feature a 15 to +30W positive power tolerance, ensuring that the actual output of each module meets or exceeds its rated power. Compared to conventional panels with zero or negative tolerance, this enables higher real-world energy generation under the same installed capacity, effectively improving overall return on investment. With stable and reliable performance, every watt you invest delivers greater value.

Frequently Asked Questions
What do I need to complete my off-grid solar power system ?
What do I need to complete my off-grid solar power system ?
A solar panel has to be connected a charge controller to regulate current, and a battery to store the electrical power. You will need adapter kit cables to wire the solar panel(s) and charge controller, and tray cables connecting the charge controller to a deep-cycle battery.
What does off-grid and on-grid mean ?
What does off-grid and on-grid mean ?
On-grid simply means solar power equipment (array or solar panel) is connected to the electrical grid, while off-grid refers to systems that are not connected to the grid and therefore store the generated power for later use. Off-grid systems are not affected by grid blackouts.
Why is my solar panel under producing ?
Why is my solar panel under producing ?
Solar panel performance 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 glass will cause a reduced power output.
How should I connect solar panels in my electrical circuit (series vs parallel)
How should I connect solar panels in my electrical circuit (series vs parallel)
Solar panels can be connected in series or in parallel to meet your electrical circuit size and power demand. Connecting solar panels in series will have the effect of adding up their operating voltage output, while system current output will be the same as that for one panel. While, connecting solar panels in parallel will have a different effect; individual panels operating current output will add up to be the system output current, while system output voltage will be the same as the output voltage of one solar panel. To meet the optimum power output and system rating for your power system, you can use both parallel and series connections.
How many solar panels do I need ?
How many solar panels do I need ?
The best way to gauge how many solar panels you need, is to understand and define the power load needed from this system. Power is measured in Watts, and 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 accordingly decide how many panels or how much power input is needed.
