KEY FEATURES This 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. 銆怱pace 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.

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? Sure, 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 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.
