This renogy bifacial solar panel 1180w review examines a pair of 590W modules designed for high-yield residential installations. The system relies on N-Type cells and a bifacial design to capture sunlight from both sides. Its key specs are a 25% conversion efficiency and a 16BB busbar count. These features aim to maximize energy harvest while reducing hot spots. The panels also carry an IP68 rating for the junction box and a robust aluminum frame. You get two panels in this set, totaling 1180W of rated power. This configuration targets users seeking durable, high-efficiency solar solutions for their homes.
What stands out
- Bifacial design captures light from both sides for up to 30% extra energy
- N-Type cells offer higher efficiency and better temperature tolerance than PERC
- IP68-rated junction box ensures waterproof performance in outdoor conditions
- 16BB technology minimizes resistance and extends operational lifespan
Who it fits
Good fit for
This setup suits homeowners with ample roof space who want maximum energy output per square foot. The high 25% efficiency means you need fewer panels to reach your power goals. The bifacial feature works best if you have a reflective ground surface, like white gravel, to boost the rear-side gain. It is also ideal for those in areas with high snow loads, as the panels withstand 5400Pa of pressure. If you prioritize long-term stability and resistance to light-induced degradation, these N-Type panels are a strong fit.
Who should skip it
You should look elsewhere if you have limited roof space and cannot orient panels to capture rear-side light. The bifacial benefit drops significantly in shaded or non-reflective environments. If you are installing on a standard dark roof without spacing, you may not see the promised 5% to 30% boost. Additionally, if you need a single panel solution, this listing sells a pair. You might prefer smaller 400W or 590W individual units if your inverter capacity or mounting structure cannot handle the full 1180W array.
Verdict: The Renogy 1180W Bifacial N-Type pair delivers high efficiency and durable construction for spacious installations. It is best for users who can leverage its dual-sided design for maximum energy gain.
Key specs explained for you
Rated Power: 1180 W
This total wattage indicates the combined output of the two 590W panels. It determines how much electricity the system can generate under standard test conditions. You use this figure to size your inverter and battery storage. A higher rated power means faster charging for your portable power station or home backup system during peak sunlight hours.
Conversion Efficiency: 25%
This percentage shows how much sunlight hits the panel is converted into usable electricity. A 25% efficiency rating is high for current technology, meaning you get more power from the same roof space. This is useful if you have limited installation area. It allows you to generate more energy compared to lower efficiency panels, maximizing your energy harvest.
Panel Type: Bifacial
Bifacial panels capture sunlight from both the front and the back. The backside absorbs reflected light from the ground or roof surface. This design can increase total energy production by up to 30% depending on your mounting setup and surface reflectivity. You benefit from higher daily output, especially if the panels are mounted above a reflective surface.
Cell Type: N-Type
N-Type cells offer better performance in high temperatures and resist degradation over time. They maintain higher energy output throughout their lifespan compared to traditional P-Type cells. This means more consistent power generation year after year. You get reliable performance even in hot climates, ensuring your solar investment yields stable energy for decades.
Busbar Count: 16BB
16BB refers to the sixteen busbars that collect current from the solar cells. More busbars reduce electrical resistance and improve current collection. This design minimizes power loss within the panel itself. You benefit from slightly higher efficiency and better performance in low-light conditions. It is a modern standard that supports the high conversion efficiency of the panel.
Design and Build Details
According to the listing, each panel measures 89.7 inches in height and 44.6 inches in width. The frame is constructed from black aluminum, which the manufacturer describes as corrosion-resistant. This material choice helps the unit endure outdoor exposure. The overall weight for the pair is 58.4 pounds. You must ensure your mounting structure can support this load. The bifacial design features a transparent backsheet. This allows the panel to capture sunlight from both sides. You can install the panels with space behind them to maximize this dual-sided energy generation.
The junction box carries an IP68 rating. This specification means the electrical connections are protected against dust and long-term immersion in water. You can rely on this seal for wet environments. The panels withstand wind loads up to 2400Pa and snow loads up to 5400Pa. These high load ratings indicate a robust physical structure. You can install these units in regions with severe weather without immediate concern for structural failure.
The modules use N-Type cells with 16BB technology. This layout minimizes resistance and improves current collection. The black finish provides a uniform appearance on your roof. The physical design supports high efficiency in diverse conditions. You get a sturdy unit built for long-term residential use.
Setup and Everyday Use
Installing this pair of panels requires handling two 590W modules. Each unit weighs 58.4 pounds. You must mount them securely to withstand the rated loads. The listing specifies resistance to 2400Pa wind and 5400Pa snow. Ensure your racking system supports these forces. The panels measure 89.7 inches by 44.6 inches. Their 1.4-inch thickness allows for standard mounting rails. You connect the IP68-rated junction boxes to your charge controller. This rating protects the electrical connections from water ingress during rain or snow. The bifacial design means you should position the panels to reflect light onto the rear side. Clear ground or light-colored roofs enhance this effect. Daily operation relies on the 25% conversion efficiency. N-Type cells provide better temperature tolerance than older types. This means the panels maintain output better on hot days. You do not need to adjust settings manually. The system generates power based on sunlight exposure. The 16BB busbar technology minimizes resistance. This helps reduce power loss during transmission. You check the output by monitoring your inverter or battery bank. The black aluminum frame blends with most roof colors. Regular cleaning ensures the transparent backsheet remains effective. Dust or debris on the rear can reduce the 5% to 30% bifacial gain. The system requires no moving parts. You simply verify the connections are tight and the mounts are secure. This setup supports long-term residential energy needs without complex maintenance.
What You Need To Own It
Owning this 1180W bifacial solar array requires compatible charging infrastructure. You must verify that your portable power station or generator input accepts the voltage and current produced by two 590W modules in series or parallel. The N-Type cells offer better temperature tolerance, but you still need to manage heat dissipation for optimal efficiency. Regular upkeep involves cleaning the transparent backsheet to maintain bifacial gain. Dust on the rear surface reduces the 5% to 30% energy boost. This setup suits users with ample roof space or ground mounting areas who need high daily yield. It fits alongside smaller generators as a primary renewable source. You should check your inverter’s maximum input limits before connecting. Ensure your racking system handles the 58.4-pound weight per panel. This pair is not for compact setups. It demands a robust electrical system to handle the 1180W output safely and efficiently.
Check before you buy
- Verify your power station input voltage matches the panel array.
- Ensure your mounting structure supports 5400Pa snow loads.
- Check that your inverter handles 1180W continuous input.
- Confirm you have space for dual-sided light exposure.
- Plan for regular cleaning of the rear transparent backsheet.
