440 Watt solar panels

In this article, we are going to introduce you to our most powerful and efficient 440 Watt solar panels. You will become familiar with the details and important information about these highly productive panels, with the convenience of which solar power can be collected anywhere in the world for many years and without harming the environment. These extremely powerful and efficient modules are gaining popularity, and our store gladly offers a wide selection of 440W solar panels.

We offer the best monocrystalline 440W solar panels

When first choosing the 440 watt solar panel you should focus on its appearance. In most cases, there are two choices of module’s cell type: mono- and polycrystalline. Polycrystalline panels are cheaper, but monocrystalline modules produce more energy. Our store primarily supplies the most efficient monocrystalline panels on the market and has 440 watt solar panels of this cell type as well as other products for sale.

Choose the type of your solar PV system

Before purchasing a 440W solar panel kit, you need to decide what kind of system best suits your needs.

Off-grid with battery banks

Many homeowners prefer to install off-grid solar systems in order to become completely energy independent. This is possible, because off-grid solar systems aren’t connected to the electricity grid, so they will continue providing electricity even when the public power grid is not functioning. This is only achievable with the appropriate equipment and batteries and is also cut off to special incentives and benefits that are only accessible for grid-tied customers.

Grid-tied with net metering

Grid-tie solar systems, also referred to as on-grid, utility-interactive, grid intertie, or grid backfeeding, are popular with both residential- and business-solar installers. They are connected to the utility power grid, which is necessary to run this PV system. It allows you to export any excess power generated by your solar panels to the electricity grid and receive credits that can later offset your energy bills.


Hybrid solar systems have the convenient features of both grid-tied and off-grid solar systems. Despite the fact they are connected to the utility grid, they have extra battery storage just in case.

How many 440 Watt solar panels do I need?

A 440W solar panel has a 440 watt rated power output. However, the actual power output depends on multiple factors, such as geographic location, shading, weather conditions, and the tilt of your panels.

To understand how many 440W panels you will need to install, you first have to calculate the amount of electricity you consume a day. Next, you need to know the number of peak sun hours (PSH) in your area. PSH describes the intensity of sunlight in a specific area, defined as an hour of sunlight that reaches about 1,000 watts of power per square meter (around 10.5 feet). Consult the map below to learn how many PHS are in your area.

For example, if you live in Arizona and your daily energy consumption is 8 kW, you will need your 440W panel kit to generate 8,000 ÷ 6.3 ≈ 1,270 kW. It means that three 440W - panels would be enough to supply your energy needs.

What can a 440 Watt solar panel run?

What will a 440 watt solar panel power? That’s a great question to ask. Using the 1,760-2,640 Wh of energy produced per day for 4-6 PSH, you can power these home appliances:

  • TV
  • Blender
  • Laptops
  • Cell Phones
  • Cameras
  • MP3 Players
  • Handheld Video Games
  • Lights/Lamps
  • Portable Stereos
  • CD/DVD Players

Advantages of 440 Watt solar panels

  • Excellent power output even in low light conditions.
  • Better efficiency thanks to half-cut cell configuration.
  • High efficiency in high temperatures.
  • Very-cost effective and price competitive.
  • Requires fewer panels due to increased energy generation.
  • Reduced installation cost since fewer panels are required to cover electricity needs.
  • Increased durability thanks to smaller cell size and therefore reduced probability of microcracking.
  • Low degradation rate.

The average price of 440 Watt panels

440 watt solar panel price is generally a bit higher than the price of most popular panels for residential installations. Which makes sense — a 440W solar panel allows you to harvest more electricity from a square foot. Currently, our online store offers a great monocrystalline model of 440W solar panel performed by LONGi for $274.41 per panel.

What size of 440 Watt solar panels do I need?

The exact size of a 440 watt solar panel depends on the manufacturer and the model. Generally, 440 Watt solar panels have 144 half-cut solar cells with measurements similar to 72 cell solar panels.  The dimensions of an average 440 Watt solar panel may vary, but are about 82.5” x 41” x 1.38”. The solar panels we currently offer weigh around 61 lbs but that may also vary.
