About product

REC 325W Solar Panel is a 120 cell module featuring class leading power output that makes it ideal for commercial and residential systems, as well as for boats and RV. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. Panels with REC TwinPeak technologies have a unique ‘Twin’ design, which enables them to generate electricity even when they are partially shaded. Cell colors, back foil and frame are kept completely black. REC solar panels are assembled in Singapore by a company that has more than 20 years of expertise.

  • 325W Power Output
  • 120 Cell, Monocrystalline (PERC)
  • 20.3% Module Efficiency
  • MC4 Connectors
  • Improved Performance in shading conditions
  • PID resistant
  • Black frame and backsheet

High Efficiency of 20.3%

REC TwinPeak 3 panels take full advantage of the company’s technologies that have won REC multiple awards. This p-type mono option offers higher power output per  m² of PV modules. This means quicker installation times and the need for fewer components such as clamps and racks. All of which reduces your overall costs, shortening the payback time.

Better Performance at High Temperatures

Excellent temperature coefficient means more energy as temperature rises. No Light Induced Degradation (LID) — no power loss. More power output thanks to low Nominal Module Operating Temperature (NMOT): 44.6 ± 2°C.

Quality and Reliability

REC’s strict manufacturing standards include multiple tests to provide extreme quality assurance. Thanks to REC’s award-winning ‘Twin Panel’ design, the company was able to reduce internal resistance for more power and reliability.

Highly PID Resistant

A low annual degradation rate of 0.7% means that a module will have no less than 80.7% of power output by year 25.

Enhanced Frame Design

REC 325W is a 120 cell solar panel featuring a sleek, all-black design coupled with outstanding power output. Its design makes it ideal for residential and commercial rooftops. Strong 38mm frame made from anodized aluminum increases durability and strength and is able to withhold a heavy snow load up to 5400 Pa.

20 Year Product and 25 Year Performance Warranty

REC provides an industry-leading 25-year performance warranty and a 20-year product warranty.

How much is shipping and how long is delivery?
Our standard shipping charge is $250 for up to 11 panels and it is increased by $25 for every 4 additional panels. In the event, the product is only available on East or West coast custom quote will be sent to you before the order is processed. Normally, we are able to deliver solar panels within 7 business days.
What is the difference between low price panels and top price panels?
With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.
What are the dimensions of the panel?
Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.
How long is the warranty on the panel?
In general, manufacturers provide a 25 year-long performance warranty and a 10 year-long equipment guarantee. Some manufacturers offer 12-15 years of warranty. More information is available in our warranty support section.
Which panels do you recommend for RV, marine?
We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.
Can this panel be used with a 12v system?
Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.
Can I pick up this panel from your fulfillment center to save on shipping?
Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.
How do I connect these panels?
To achieve the best system efficiency, panels should be connected in series to create higher voltage.
How many panels do I need?
This number is determined by your average energy needs. Depending on the type of panels and energy consumption, you might need anywhere from 12 to 45 solar panels. Remember, the more panels you install the more energy you will get.Please use our solar calculator to estimate your energy consumption and plan on building a solar system that will exceed your energy needs by 25%.
Do you offer discounts?
We do offer discounts for orders of over 50 units. Please contact us for details.
How do I build a solar system?
Please use our solar calculator to estimate what equipment you need. Choose your panels, microinverters, inverters, and solar batteries if necessary.Please note that we do not offer solar system design or installation.
How do solar panels compare?
Solar panels differ by power output, voltage, connection type, size, efficiency, and weight. Some solar panels might be sold together with microinverters as a set.
Can I build a solar system by myself as a Do It Yourself project?
Yes, it is possible if you understand what solar equipment you need and how to connect it together. However, please be mindful that handling your own electrical work without having proper experience might cause life-threatening injuries. Please contact a certified electrician if you do not possess appropriate electrical skills.
Can I connect and charge my solar panel battery directly with the solar panel?
We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.
Can I drill holes into the aluminum frame for mounting?
We do not recommend drilling any new holes to the aluminum frame of the panel as it could damage the internal circuit and solar cells. (Also, any modification to the panel will void the warranty). We recommend only using the pre-drilled holes for mounting.
Do solar panels require maintenance? Can I wash my solar panel?
Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.
Will my panel produce power in an overcast condition?
While solar panels require sunlight to generate solar energy, they will still work in cloudy weather. Even on a cloudy day, solar panels will produce energy just not as much.
Will my panels produce power if covered with snow?
Solar panels cannot produce electricity if covered with snow.
What is the best direction for a solar panel to face?
The best direction for a solar panel to face is the South
