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.

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.

    Panels performing better than expected.

    Posted by Troy on Jan 11th 2024

    They are producing good output especially after I tilted them to point at the optimal angle for the late fall. The packing was excellent, which I expected for a relatively expensive and fragile product. I wish any of the Renogy kits to tilt the units worked for large (>200 watt) panels but I was able to build my own.

    Renogy provided great support

    Posted by BGJCK on Jan 5th 2024

    When the first panels arrived damaged, RenewableEnergyUS immediately worked to get the new panels delivered. Customer service was very responsive and new panels arrived today. Looking forward to getting them hooked up to try out this bifacial technology.

    good quality panels and shipping less expensive than buying direct from manufacturer

    Posted by Daniel V. Wilder on Jan 1st 2024

    I use these panels to run an air conditioner/dehumidifier in my shed.? They are great panels, I have bought many before (mostly 200W earlier).

    Bigger than you think

    Posted by Robert and Sherry Kraus on Nov 5th 2023

    The panels worked great, but if you are doing a self installation I¡¯d recommend going with more smaller panels. Two small panels are much easier to handle than these monsters. But if you have limited space, these are a great choice.

    Great customer service

    Posted by Alex Opal Hall on Oct 29th 2023

    After placing my order there were some set backs with delivery. Renogy did everything they could to make certain that we were taken care of. These 450 bifacial panels are great and have been giving incredible results. My solar set up is complete and getting great input numbers per panel. I've found that 2 worked together gives at least 1kwh during peak sun. Can't complain about that ??

    Better than there 450w non bifacials

    Posted by Amazon Customer on Sep 17th 2023

    Have only had these up and running for a few days but have already seen them hit 510w each. The non bifacial versions of these exact panels the most i've seen so far was 404w each (been installed on the rack for over 3 months as of this review)? Will probably get a few more of these in the near future. Purchased a 2 pack on August 28, 2023 for $805 after tax.

    The best Solar connection for overcast

    Posted by Elegos23 on Jul 31st 2023

    Bi- Facial mono panels are insanely better for the mobile crowd. The additional 10-30% of solar collections from indirect sources do make s huge difference. Put on roofs they lack luster unless someone is mounting mirrors and giving enough gap between panels for light to bounce around. They're also more efficient in overcast, so if your living in an area like the PNW like myself you see the difference those treats facing crystals help. Just be ware of the increased voltage as well. Especially if your purchasing 10bb panels.
