Product guide

AeternaSol D1440T 200W Bifacial Solar Panel

The AeternaSol D1440T is listed as a 200-watt bifacial solar panel with MC4 connectors and an IP68-rated junction box. Its double-sided design is intended to collect reflected light as well as direct sunlight, while actual output depends on conditions such as angle, temperature and shading.

At a glance

The listing describes N-type monocrystalline cells and 18 busbars, with claimed conversion efficiency of 25% in feature text and 25.6% in the title.
Bifacial construction is claimed to capture reflected and diffused light from the rear, with a stated possible gain of up to 30% under suitable conditions.
The frame has pre-drilled installation holes, and the listing specifies MC4 connectors and an IP68-rated junction box.
The listing describes the panel as suitable for 12V systems. Its stated output voltage is 18 volts, so 12V refers to system suitability rather than panel output voltage.
Manufacturer listing states a 5-year material and workmanship warranty and a 25-year performance guarantee.

Pros and cons

Pros

Bifacial design may make use of reflected light when the rear side has an unobstructed, bright surface.
Pre-drilled frame holes can simplify mounting where the chosen installation hardware is compatible.
MC4 connectors are a clearly stated connection type for planning a compatible system.

Cons

Actual power can be below the 200-watt rating depending on sunlight, panel angle, temperature, shading, wiring losses and connected-device efficiency.
Bifacial output depends on reflected light reaching the rear face, so the claimed gain is not assured in every installation.

What to know before buying

The listing notes that 200 watts is a Standard Test Conditions rating and that real-world output varies with installation and operating conditions. Its 12V wording describes system suitability, not the panel’s stated 18-volt output.

Listing details to confirm

The listing has contradictory power and bundle details: the title and feature copy describe one 200-watt panel, while the highlight and included-components field describe two panels totaling 400 watts. Efficiency is stated as 25.6% in the title and 25% in feature text. Confirm the selected listing’s panel count and rating before purchase. The claimed bifacial gain, warranty and long-term performance figures are manufacturer statements, not independently verified results.

Who is it for?

A good fit for

RV, marine or off-grid system planners who need a panel listing with MC4 connectors and a stated 200-watt rating.
Installations that can expose the panel’s rear face to reflected light and provide suitable mounting space.

Less suited to

Buyers who need a guaranteed 200-watt real-world output or a guaranteed bifacial gain.
Buyers who cannot confirm whether their selected listing includes one panel or two.

Customer feedback highlights perceived quality and performance, but reports on power output and durability are mixed. Some customers describe output around 300 watts, while others report about 170 watts per panel, illustrating that reported results vary and should not be treated as guaranteed. One durability report mentions a separating silicone seal, while another describes a panel arriving in perfect condition. These reports matter when weighing the listing’s 200-watt rating and construction claims, but they do not establish expected output or a general defect.

Positive themes

Customers report good quality and performance, with some describing output at or above listed ratings.
Some customers regard the panels as good value.

Mixed feedback

Customer reports of power output vary, including reported 300-watt production and around 170 watts per panel.
Durability feedback includes both a report of a separating silicone seal and a report of a panel in perfect condition.

Frequently asked questions

Does the panel produce 200 watts continuously?

No. The listing describes 200 watts as a rating under Standard Test Conditions. It says actual output depends on factors including sunlight, angle, temperature, shading and system losses.

Is this a 12-volt panel?

The listing says it is suitable for 12V systems, while its stated output voltage is 18 volts and maximum voltage is 24.96 volts. Confirm system and controller compatibility before connecting it.

Does the panel include bifacial output gains of up to 30%?

The listing claims up to 30% additional output from reflected and diffused light. That depends on rear-side exposure and installation conditions, so it is not a guaranteed gain.

How many panels are included?

The listing is inconsistent. Its title and feature copy describe a 200-watt panel, while the included-components field says two panels and another highlight says 400 watts total. Confirm the selected listing's bundle before ordering.
