Renogy 550 Watt Monocrystalline Solar Panel Overview
This Renogy High-powered 550-Watt Monocrystalline Solar Panel maximizes power output while minimizing installation space and system equipment costs, primarily used for utility-scale systems, solar power plants, residential and commercial applications. This solar panel combines high efficiency mono PERC cells with Half-Cell and 10-Busbar technologies to improve the electrical performance and power output of your solar array system. Generate renewable energy, reduce electricity bills and carbon footprint.
A High-Powered Module: The Renogy Monocrystalline 2-piece solar panel is engineered with high-efficiency PERC (Passivated Emitter and Rear Contact) cells, capturing more light to achieve 22.8% conversion efficiency. Resulting in higher performance than most conventional panels, Renogy's 550-watt panels provide more output per surface area.
High Tolerance: Renogy's high-powered 550 watt solar panels are made with half-cell technology. This half-cut panel is more tolerant of shading on any part of the cell and performs excellently in low light situations due to the increased number of cells receiving more sunlight.
Space and Installation Optimization: A great option for large-scale installations, each solar panel can produce up to 2750 Wh of electricity per day and requires fewer installations per panel on your rooftop.
Reliable and Durable: Corrosion-resistant aluminum frame provides extended outdoor use that ensures the panel can last for decades. The IP68 rated junction box and solar connectors can withstand dirt, dust, debris, and water splashes.
Federal Tax Credit: Claim up to 26% of your home's new solar system costs (both equipment and installation) for a tax credit.

Frequently-Asked Questions
1. Is each panel 550W or a whole combination? What about the size and weight?
550W per panel. The dimension of one panel is 89.7 x 44.6 x 1.4 inches, and the weight is 62.8 lbs.
2. How many kWh a day does this solar panel produce?
If your solar panels are exposed to 5 hours of direct sunlight per day, it can provide an average of 2200-2750 Watt-hours (2.2 kWh - 2.75 kWh) of electricity (depending on sun availability).
3.Why choose this high-powered 550W module rather than 5-6 100W solar panels?
High-powered solar panels are primarily used for utility-scale systems, solar power plants, solar farms, residential and commercial applications. Compared with 100 Watt solar panels, these high-powered 550 Watt modules provide maximum power generation for your limited roof space. They also allow the use of fewer mounting systems, including wiring cables, screws, or mounting brackets.
4. Can these panels be used on a grid-tied system?
Yes, they can. These high-powered 550 Watt solar panels work with on-grid, off-grid, and hybrid systems. But please note that when using them on on-grid and hybrid systems, we recommend that you contact a licensed solar installer familiar with on-grid/hybrid setups.
On-Grid solar system means solar power equipment (array or solar panel) is connected to the utility grid.
Off-Grid solar system refers to a system that is not connected to the grid. An Off-Grid system is not affected by grid blackouts.
A Hybrid system is when your solar panels remain connected to the grid's power lines and have a backup battery system to store excess power.
5. How should I connect solar panels to 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. The output current 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 your power system's optimum power output and system rating, you can use parallel and series connections.
6. Do these panels have pre-drilled holes on the back?
Yes, they have. The pre-drilled holes help you to install the solar panel quickly and securely.
7. Can this solar panel be adapted to a 12V Marine Battery or 48V Lithium Battery?
Yes, it can. The optimum operating voltage of this 550W solar panel is 41.97V. So it's suitable to use for charging your 12V Marine Battery and 48V Lithium Battery (by connecting at least two solar panels in series). Please note that you need to connect the solar panel(s) to a Charge Controller supporting a 12V or 48V system.
8. What do I need to have to complete my off-grid solar power system?
Here’s a list of all the equipment required for a functioning off-grid solar system:
Solar Panels, Solar Charge Controller, Inverter(s), Battery, Mounting and Racking System, Wiring Cables, and Fuses.
Ordered just the inverter and one battery. My goal was to power the house during occasional power outages that the TVA likes to use to manage anomalies. I do NOT have solar. I have a 50 amp generator inlet box on the outside of the house, so I ordered a cable to go from the 30 amp twist lock to the 50 amp twist lock. After charging the battery and switching the manual interlock, the house did indeed come to life. I was able to use one of the medium size burners on the induction cooktop on high. One big question I had, and had gotten conflicting answers on, was whether I could plug my small generator into the 120 V charging inlet, and get 240 V out to the house at the same time. It worked! That way if the outage should last for an extended time, I would be able to keep the battery charged with the generator, while still getting some power to the house. You could see on the panel that 1800 watts were going in, almost 4000 watts were going out. Over time, I would expect that as long as my average draw was 1800 watts or less, I would have power as long as I could keep the generator gassed. I was NOT able to run my 2-1/2 ton central air, but honestly I was not expecting to be able to. Even on utility power the lights noticeably dim when the unit kicks on. Possiblly a soft start might do the trick. So for me, it solved the problem I was concerned with. One nice bonus is that I plugged the tankless water into one of the front AC plugs. That way the water heater won’t shut off in the middle of a shower if the power blips. When that happens the water goes cold really fast and makes for an exciting day.

Outstanding, we're thrilled you're happy with your purchase and it was our pleasure to serve you. Thank you!
Started up just fine, and output was stable. Not a big fan of the screws that hold on the side cover, but a great deal for the money to me. My testing so far is only about 40 min with an intermittent 400 watt load. I changed the oil, and the next chance I get I will run it some more. The unit does not take much oil, so I will change the oil often. SUPER QUIET compared to my old gas generator. I love that! I was going to give the unit a 4, but I like how quiet it is more than care about the screws.
Thanks so much for your honest feedback. If there is anything we can ever do to be of service, please let us know!
