Renogy's 550-watt solar panel is a high-powered module engineered with high-efficiency PERC (Passivated Emitter and Rear Contact) cells, achieving an impressive 22.8% conversion efficiency. This panel excels in low light conditions due to its high tolerance to shading, making it ideal for large-scale installations. Each panel can generate up to 2750 Wh of electricity daily, optimizing rooftop space usage.
The panel's reliability is enhanced by its corrosion-resistant aluminum frame, IP68 rated junction box, and solar connectors. Additionally, you can claim up to 30% of your solar system costs as a Federal Solar Tax Credit, making it a cost-effective and environmentally friendly choice for your home.
PRODUCT HIGHLIGHTS
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.
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.

What is the Benefits of Using Bifacial Solar Panels?
Captures sunlight from both sides
More efficient and powerful than monofacial panels
Perform better in overcast weather
Can be installed in any direction
What do I need to complete my off-grid solar power system?
A solar panel has to be connected to 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?
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 underproducing?
Solar panel performance may be hindered for a number of reasons. Most commonly, environmental conditions such as indirect sunlight, temperature rise, cloudy skies, and dirt and stain buildup on the top glass will cause a reduced power output.
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. Connecting them in parallel will have a different effect; individual panels' operating current output will add up to be the system output current, while the 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?
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.

I'm really impressed with the size and performance. I got the 550-watt ones and they're much bigger than I expected. Set them up on my lawn to test and they topped out at 1135 watts despite a sub-optimal angle. There was consistent power generation of 450 to 550 watts over a few days of testing. They easily meet their rated output, even on overcast days. They are great!
