About product

Solaria PowerXT All Black Mono 370 W is another great example of the Solaria product line. With this model the engineers have reworked the structure of a solar panel and achieved the efficiency of over 20% plus improved appearance of a module. The uniform black surface makes the panel look stylish on the roof of any house. The panel is suitable both for residential and commercial use.

High Efficiency of over 20%

Solaria PowerXT 370W solar panel shows 20.5% efficiency whereas conventional PV modules only reach 15-17%. Better efficiency allows you to harvest more energy with fewer modules and less space.

Weather & High Temperatures

The tests show that PowerXT retains good power output even when irradiance falls down due to cloudy weather. High temperatures don’t pose a serious threat to panel’s performance: the temperature coefficient of Pmax is at -0.39% per °C. What is more, Solaria PowerXT 370W solar panel has 4 bypass diodes in its construction which improves the overall shading tolerance of a PV module.

Enhanced Resiliency

The frame is made of black anodized aluminium. The PV module is able to withstand the 5600 PA load on the front and 3600 Pa load on the rear side. Solar cells are protected by a 3.2 mm layer of tempered glass.

All-Black Aesthetics

The appearance is where Solaria panels outshine most of their competitors. With PowerXT, Solaria engineers have reduced the space between cells which made the appearance of a panel more uniform and appealing. Black backsheet and frame make this solar panel look outstanding on top of the house.

25 Year Product and Performance Warranty

For the PowerXT 370W model the Solaria Corporation gives a 25 year manufacturer warranty and also 25 year performance warranty — the power output of a module should not drop below 86% of minimum performance.

I'm thinking about getting the 3 of the 370 Watts at 24 volts, I'm wondering how I would set them up to do so.

You need to check you charge controller datasheet


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
