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

Among the newest offerings of Sunpro Power, SPDG585-N144M10 is part of the TOPCon 182 BIFACIAL series. These panels use state-of-the-art technology to achieve high efficiency and dependability.

Each of the panel’s 144 cells is only half the size of a traditional solar cell. This grants SPDG585-N144M10 lower resistive losses and better shade tolerance. As a result, the panel achieves an impressive efficiency of 22.64%. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. Sunpro Power paid as much attention to durability as they did to performance. SPDG585-N144M10 is guaranteed to retain at least 87.40% of output after 30 years. The quality guarantee for this panel lasts 15 years.

  • 585 W power output
  • 144 half-cut TOPCon N-type cells
  • 22.64% efficiency
  • 1500 V DC maximum system voltage
  • MC4-compatible connectors
  • 15-year quality guarantee and 30-year power warranty

Higher efficiency of up to 22.64%

SPDG585-N144M10 guarantees the highest power output. TOPCon N-type cell technology and potent antireflective coating result in 22.64% module efficiency. This is significantly higher than average, which will result in substantial extra savings over the years of operation.

Heat-resistant performance

This module makes the heat less dangerous since it has one of the lowest temperature coefficients in the market, losing just -0.3% of efficiency for every 1.8°F over 77°F.

High-quality standards

Sunpro Power's stringent production requirements include various tests to guarantee high quality. The facilities are highly automated, allowing the manufacturer to maintain high standards while keeping warranty claims to a minimum.

Reliability and degradation resistance

Slow degradation over the next 30 years is guaranteed by Sunpro Power. The performance will decrease no more than 1% during the first year and 0.4% annually thereafter. Your modules will retain at least 87.40% of their original performance after 30 years. This 585 W Sunpro Power solar panel also comes with a generous 15-year quality guarantee.

Certified for the most challenging environmental conditions

SPDG585-N144M10 is resistant to PID, salt, acid, and ammonia. It can also withstand up to 5400 Pa mechanical load on the front and 2400 Pa on the back. Such robustness is mainly due to the 1.18" thick anodized aluminum alloy frame and a layer of protective glass.
