400 Watt solar panels


In this article, you will find the essential specifications of our most powerful and efficient 400 Watt solar panels. With the help of these highly productive modules, solar power can be collected anywhere in the world for many years and without any harm to the environment. These powerful PV modules become more and more popular, and you can find 400W solar panels for sale in our store as well.

Types of 400w solar panels

When choosing the solar panel 400W, first you should look at its photo elements. There are mainly two choices: mono- and polycrystalline cells. Polycrystalline panels will be cheaper, but monocrystalline modules will produce more energy. In our store we deal primarily with the most efficient monocrystalline panels on the market and have 400 watt solar panels for sale among other products.

Choose the type of your solar PV system

Before purchasing a 400W solar panel kit, you need to decide what kind of system you want.

Off-grid with battery banks

Many homeowners prefer to install off-grid solar systems to become completely energy independent. The thing is that off-grid solar systems aren’t connected to the electricity grid, so they will continue working even if the public power grid is not functioning. However, this is only achievable with the appropriate equipment and batteries.

Grid-tight with net metering

Grid-tie solar systems, also referred to as on-grid, utility-interactive, grid intertie or grid backfeeding, are popular with both homes and businesses. They are connected to the utility power grid, which is necessary to run the PV system. It allows you to export any excess solar power you generate to the electricity grid, receive credits and use them later to offset your energy bill.

Hybrid

Hybrid solar systems incorporate the best features of grid-tied and off-grid solar systems, hence the name. Despite the fact they are connected to the utility grid, they have extra battery storage as a backup./p>

How many 400 Watt solar panels do I need?

A 400W solar panel has a 400 watt rated power output. However, the actual power output will depend on many factors, such as geographic location, shading, weather conditions, and the tilt of your panels.

To understand how many 400W panels you need to install, you have to calculate the amount of electricity you want to consume a day. You also 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 there are in your state.

For example, if you live in Arizona and your daily energy consumption is 9 kW, you will want your 400 W panel kit to generate 9,000 ÷ 6.3 ≈ 1,500 kW. It means that you’ll need 4 panels 400W to cover your energy needs.

What can a 400 Watt solar panel run?

What will a 400 watt solar panel run? That’s a good question to ask. Using the 1,600-2,400 Wh of energy produced per day for 4-6 PSH, you can power:

  • Small televisions (up to 32″)
  • Blender
  • Laptops
  • Cell Phones
  • Cameras
  • MP3 Players
  • Handheld Video Games
  • Lights/Lamps
  • Portable Stereos
  • CD/DVD Players

Advantages of 400 Watt solar panels

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

The average price of 400 Watt panels

400 watt solar panel price is generally a bit higher than the price of most popular panels for residential installations. Which makes sense — a 400 W solar panel allows you to gain more electricity from a square foot. We have a variety of 400 watt solar panels for sale. Our online store offers a few models of 400 Watt solar panels in the price range from $230 to $280.

What size of 400 Watt solar panel do I need?

The exact size of a 400 watt solar panel depends on the manufacturer and the model. In general, 400 Watt solar panels have 144 half-cut solar cells with measurements similar to 72 cell solar panels. Of course, the number of cells in a module reflects on the 400W solar panel price. The dimensions of an average 400 Watt solar panel are about 79” X 39” X 1.4”. The 400 watt solar panel size and power output ratio make it a good option for solar installations with space constraints. The solar panels we currently offer weigh between 48 and 50 lbs.
