About product

Certainteed CT-SERIES 315W is an aesthetically attractive all-black module that not only looks good, but also shows outstanding performance. The module employs half-cut 6″ solar cells that are tightly stacked together leaving almost no gaps, which gives the panels a solid look. The cells are protected by a 3.2 mm layer of tempered glass. It is high transmission and has an anti-reflective coating, making solar energy harvesting more efficient. 3 bypass diodes allow this model to perform better in partial shade, making it an optimal choice for dealing with the issue.

Outstanding 19% efficiency

Certainteed CT-SERIES 315W is a monocrystalline module with an efficiency reaching 19%, which is not very far from the products of top manufacturers. The model has a low temperature coefficient of -0.37%, meaning that it loses just 0.31% for every 1.8°F above 77°F. Superb efficiency and decreased weather-driven losses result in higher final energy output.

Panel that will survive any storm

This solar panel can operate in very harsh settings. A 35 mm anodized aluminum frame is rigid enough to support heavy snow loads. The front side of the module can take a load of up to 5,400 Pa or 112 lbs/ft2, while the back is good at resisting winds of up to 2,400 Pa or 50 lbs/ft2. The solar cells are protected by a 3.2 mm layer of tempered glass.

25-year product and performance warranty

Certainteed CT-SERIES 315W is also degradation-resistant. Certainteed guarantees that the real output of the module will not go below 97% during the first year. Following year one, the annual degradation rate will be limited to 0.71%. By the end of year 25 your panels will retain at least 80% of their nameplate capacity. Certainteed includes a standard 10 year product warranty for all of their solar panels.

Some companies offer multiple warranties for different system components. Certainteed gives you one that already covers everything, even installation, if you work with their installers. That’s what draws me most to their products

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
