330W Solar Panel330W Solar Panel.

This 330w solar panel is good for a many applications. It is handy to use as a source of power to charge batteries or to use for either AC or DC appliances.

This is a handy and improved 330w solar module. This is a product of the USA, which they manufacture in Georgia & Michigan.

They call it the Suniva OPT330-S38-W3A02-W, 330 Watt Mono Solar Panel.

These high-powered modules consist of Suniva’s premium ARTisun® Select cell technology.

They manufacture the module by making use of proprietary low-cost processing techniques.

With their ION implantation technology, they ensure value, performance, and reliability.

(Ion implantation is a technique that improves solar cell efficiency. It cut process steps in standard and advanced cell designs.) 

It comes with a 25-year limited output warranty.

They use Monocrystalline cells to build the 330w solar panel.

It comes with the normal 3 buzz bars between cells. A 5-buzz bar option is also available. 

Performance of the 330w solar panel

On a sunny day with 7 hours of sunlight in mid-summer, you can bargain for the generation of about 1960 watts.

That is 7 x 330 watt = 2310 watt.

Now you allow for a loss of 15% and you get 2345 X 85/100 = 1963.5 watt.

Round the 3.5 and you get a fair 1960 Watt.

The module is for residential purposes. You can also apply it for commercial use.

Use the 330w Solar Panel from the USA for off-grid or on-the-grid applications.

The size of the panel is 77.6" × 39" × 1.5".

The 330w solar panel has cables attached to it via the junction box. The cable length is 1300 mm.

How does the 330w solar panel work?

The Suniva 330W Monocrystalline panel is ready to generate cheap energy. Direct it to the sun and it is in operation.

It produces a DC voltage. To use it for proper residential or commercial purposes you need a charge controller. This is to act as a regulator for the batteries that store the electric power.

You will also need an inverter. This is to change the direct current to alternating current if you want to go 110 or 220 volts.

Silver Anodized Aluminum Frame

The module comes with a silver anodized aluminum frame. This ensures safe outdoor use for many years.

The manufacturer uses glass with tempered (low iron), anti-reflective coating. This is to get greater transparency and less loss of light due to reflection.

The Suniva 330W Monocrystalline panel can endure a front-load up to 2400Pa. It can also resist wind of high speed. This is because it comes with a reinforced frame design. 


The 330w solar panel comes with a Nema IP67 rated, waterproof junction box.

The box is durable and can last for many years. It provides complete protection against harsh weather conditions.

The junction box contains six internal diodes. In the case of partial shading, the diodes activate. It bypasses any current generated by non-shaded cells. This is to limit module heating and performance losses.

The diodes ensure a constant output.


The 330w solar panel provides a high-power output per square meter at an affordable price.

It comes with rigorous in-house quality management tests. That goes beyond standard UL and IEC standards.

The manufacturer uses an advanced polymer back sheet.

It comes with a positive-only power tolerance. (Power tolerance is a measure of how much electrical power a solar panel can produce. This is above or below its rated capacity at any time.)

The module comes with a marine-grade aluminum frame with a hard-anodized coating.

These Optimus® modules come with high quality and long-term reliability.

It comes with a durable frame. It is corrosion-resistant and good for extended outdoor use for many years.

These 330w solar panels can withstand heavy snow loads and high-speed winds.

They certify the module PID-free. 


The module comes with a 25-year linear power warranty and a 10-year product warranty.

In a conclusion

The Suniva 330w solar panel is of high quality. The manufacturer sees to it that the testing is thorough.

It comes with an efficiency of 16.9% and high power output per square meter.
