About product

REC Twinpeak 2 modules are a powerful and modern choice for a residential solar system. Split cell design provides better shading tolerance, durability and higher efficiency. The model comes with a 20-year product warranty and 25-year performance warranty.

  • 300-320W power output
  • up to 19.2% efficiency
  • 120 half-cut monocrystalline cells
  • Better shading tolerance
  • MC4 connectors
  • Made in Singapore

High efficiency with half-cell design

This model is an example of breakthrough technology that REC introduced: half-cut cell design. Smaller cell size allows for higher production from a square foot. While this 120-cell panel is comparable in size to a standard 60-cell panel, it produces more energy and allows you to use your space more efficiently.

Prepared for harsh weather conditions

REC TP2 shows great resilience to extreme weather conditions. The module can withstand up to 2400 Pa wind load and up to 5400 Pa snow load. Half-cut cell technology makes cells more durable and prolongs the lifespan of a panel. The panel is fully protected from potential induced degradation (PID).

Proven high quality is backed up by strong warranties

The Norwegian manufacturer is known for the high quality of its product. Every REC module undergoes third-party testing. This model in particular comes with a 20 year product warranty — much higher than most Chinese competitors offer. There is also a 25 year performance warranty. A module loses 0.7% of its output annually and no more than 2.5% in its first year.

The service is great and the delivery was on time. The panels themselves look high quality and do produce a lot of power. So far I'm quite satisfied — we’ll see what the future brings.

thank you for the recommendation earlier! i was really wondering about this split cell technology, cause i needed something to fight shading well. This one does alright!

Not the most modern, but still a great panel and for a really fair price.

Oh, I know this module! My friend has had it for a couple of years already. He said that it’s a great module to have and he really likes rec panels in general

Singapore? I thought rec was norwegian

It is a Norwegian brand, yes. However, their production facilities are located in Singapore.
what kind of inverter would you recommend with that panel?
11/27/2021, 10:03
Good day. Well, it depends on the size of your system. If you don’t plan on adding the batteries, any grid-tie inverter will do. We receive a lot of positive feedback on the SolarEdge brand.
i’m not really into deliveries, can I grab them myself from somewhere?

Sure thing. The list of available pickup locations is under the price.


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
