- Bifacial energy yield up to 30%
- More energy, even in partially shaded areas
- Up to 30% Residential Clean Energy Credit
- More generation on a snowy day
- Enhanced 25-year performance warranty
Bifacial Energy Yield up to 30%
With the ability to capture sunlight from both sides, this panel can provide up to 30% more energy compared to traditional solar panels.
Our panels are compatible with mainstream trackers. By leveraging optimal angles and open spaces, you can maximize solar energy generation and experience the peace of mind that comes with being self-sufficient.
Rest assured, you won't waste a single watt. Thanks to the high efficiency of bifacial panels, any excess energy generated by your solar panels can be stored in batteries for future use or sold back to the main power grid. Installing a solar roof is a wise financial decision that enhances the value of your home.
Built to Last in Any Weather
Renogy solar panels are meticulously designed and third-party validated to withstand strong snow loads. Tested with a static load of 113 psf (5400 Pa).
Improved Performance in Shaded Conditions
With its innovative design that incorporates PERC, half-cut cell, bypass diodes, and 10 busbar technologies, this panel can maximize energy output even when partially shaded.
More Generation on a Snowy Day
The bifacial design of our solar panel helps to accelerate snow shedding and warm up the panel more quickly. Additionally, with the back side always available, our panel can continue to provide unstoppable solar power for your off-grid life.
Versatile Mounting Method
Embrace a variety of installation methods and strategically plan your energy solution now!

1. What is the Benefits of Using Bifacial Solar Panels ?

a.Captures sunlight from both sides b.More efficient and power than monofacial panels c.Perform better in overcast weather d.Install in any direction

2. 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.

3. 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.

4. 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.

5. 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.

6. 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.

    Great deal

    Posted by Nick green on Jan 12th 2024

    I love these because yes they are big but you only need to wire two and they work outstanding I will be buying more.

    Big and heavy and average output. Max 900W for 2 panels

    Posted by St8kout on Jan 10th 2024

    I was really hoping to hit at least 1 KW, but 900W for 2 in series has been the max from the Las Vegas sun. In comparison, it takes 12 - 100W Renogy panels to give me ~ 900W. I have them leaning against a bright block wall at about 45 degrees, where they get full sun from morning to evening. Maybe they are supposed to be mounted up high and out in the open to get reflected light. I would need a heavy duty pole mount for that.

    The 550 watt is massive

    Posted by Skworld on Jan 4th 2024

    These things are massive. In size and output. Bought the 550 watt panels and did not realize how big these things really are. Going to use it as a screening setup. Laid them on my front grass in not the best angle for testing and saw a peek of 1138. The two days of testing they would still see between 450 to 550 when clouds passes just laying on the grass. These panels easily make there rated output and do well on cloudy days. They are great!

    The 2 Renogy Bifacial 550 Watt Solar Panels arrived safely and were installed.? However, the glass surface of the front of the panels was abraded? discolored maybe by contact with the cardboard packing.? There was no soft packing in between so when shipped, the moving and jiggling may have caused this.? I tried cleaning the surface but nothing works.? Hope it doesn't cut down on the efficiency.

    As advertised on power production.

    Posted by Michael Trace on Sep 19th 2023

    they got up over 1300W peak, so glad I didn't get another panel as my charge controller only supports up to 1500W.
