I was looking for an affordable option but still something reliable. The warranty the company offers is amazing and really makes me at ease to make such an investment. Panels look very sleek, will update my review when know more of their performance.

Compared different panels across the board, and the 20 -year product warranty really sold us as did the quality and efficiency of the panel itself. Also, can't beat the price of these modules.

FAQ

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%.
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

About product

REC TwinPeak 2 Mono

Based on the multiple award-winning REC TwinPeak technology, REC TwinPeak 2 Mono panels bring heightened efficiency to REC's portfolio. Building on REC's long experience with half-cut cell technology, the REC TwinPeak 2 Mono Series uses p-type monocrystalline PERC cells, offering an even greater efficiency and power, making this Series suitable for all applications and system sizes, anywhere in the world!

FEATURES

REC TwinPeak 2 Mono features REC's innovative design with the high panel efficiency of up to 18.9% and power output of monocrystalline cells, enabling you to get the most out of the space available – helping to lower your energy bills and shorten the payback time through increased yield and lower costs.

MORE POWER OUTPUT PER M2REC TwinPeak 2 Mono panels are packed with the same advanced REC TwinPeak technologies that have won REC multiple awards. This p-type mono variant offers higher power output per square meter of panels installed. Compared to standard 60-cell panels on a multicrystalline (poly) platform, you get at least 25 Wp more per panel!

MORE PERFORMANCE IN SHADED CONDITIONS Panels with REC TwinPeak technologies have a unique “twin” design, which enables them to generate electricity even when they are partially shaded. Over time, you get a higher yield from your installation.

MORE COST EFFICIENT By delivering more power per square meter, you need fewer REC TwinPeak 2 Mono panels to generate the same power. 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.

LOW DEGRADATION Low 0.7% annual degradation rate after an initial first-year degradation of only 2.5% that results in a performance guarantee of no less than 80% of the nominated power by year 25.

ENHANCED FRAME DESIGN Strong anodized aluminum frame increases durability and strength and is able to hold a heavy snow load up to 3600 Pa and wind load up to 1600 Pa.

EXCELLENT WARRANTY REC TwinPeak 2 Mono comes with a 20-year enhanced product warranty and a 25-year linear power output warranty.
