Entering into the solar energy market for the first time can be a boring task. Right? With such a wide range of solar panels that come in various sizes and shapes, it is easy to get lost and confused in the chaos of it all.
But you need to fret as you have come to the right place. We’ll help you out by introducing you to the 400 watt solar panel. These panels are some of the biggest in the market in terms of electrical output.
So, sit back and relax because this guide contains every detail related to the 400w solar panels, from their types to their use and cost. Now, let’s quickly proceed to the details.
All About 400 Watt Solar Panel
The 400 solar panels work by absorbing sunlight from the sun and then converting this light into electrical energy. Plus, this electrical energy can be utilized to provide powers to several things such as homes, cars, yachts, and even aircraft. Also, these solar panels come in a wide variety of shapes and sizes.
However, among other things, if you are planning to install a solar panel, then you must ask yourself some important questions such as:
- What do you wish to use this solar panel for?
- How much space do you have available for the installation of a solar panel?
- How much power do I need to run all my desired appliances?
Types of a 400 Watt Solar Panel Available in the Market
There are 3 types of 400 watt solar panels available in the market. These solar panels are given below:
- Monocrystalline Solar Panel: The first type of 400-watt solar panels available in the market are Monocrystalline solar panels. These are also known as single crystalline silicon panels. These panels are covered by pure silicon and they have an efficiency of 19% to 20%.
- Poly-crystalline Solar Panel: Another type of solar panel is Polycrystalline. They have multi-crystalline cells. Also, their efficiency is around 16% to 17%.
- Bifacial Solar Panel: The 400w Bifacial solar panels are modern technology panels. They collect the sunlight from both the front and back sides. These panels have a high efficiency of 22%. However, these are quite expensive than other solar panels.
How Do 400 Watt Solar Panels Work?
As we mentioned earlier, solar panels are categorized as per their output capacity. A 400-solar panel is capable of absorbing enough sunlight to convert it into 400 watts worth of electricity.
Usually, an average 400 watt solar panel is able to produce between 1,200 Wh and 3,000 Wh of electrical energy every day. However, there are other several factors that fluctuate the solar panel results, including:
- The amount of shade over the panel during the day
- The angle at which the solar panel is tilted
- The amount of dirt on the surface of your panels
- The temperature around where your panel is installed
- The geographical location of your solar panel
What are the Uses of a 400-Watt Solar Panel?
The 400 watts solar panels are quite powerful. They have multiple applications for both residential and commercial projects. Below are some of the key uses of these solar panels:
- Residential Energy Needs: A 400 watt solar panel is suitable for providing sufficient electricity for your homes. You can use them for running your ACs, TVs, mini fridges, etc.
- Commercial and Industrial Applications: These solar panels are also suitable for all industrial and commercial applications, such as for factories and offices where large-scale energy is required.
- Off-grid Living: If you live in a remote area where a grid connection is available, then you can consider installing these solar panels as they provide reliable electricity without any costly backup system.
- Recreational and Outdoor Uses: If you are an outdoor enthusiast, then you can go with 400 watts solar panels as they will help you in providing power to your appliances, lighting, and electronics while on the go.
What is the Price of a 400 watt Solar Panel in India?
The price of an average 400-watt solar panel depends on the type of solar panel. If you want to buy a solar panel, then it is essential for you to do proper research. There are several factors that affect the price of a solar panel, such as manufacturing company, panel size, and the quality of the cells. Below is a snapshot of 400w solar panel prices as per their types:
| 400-watt panel type | Solar panel price (400-watt) |
| Monocrystalline panels | Rs. 10,800 to Rs. 13,200 |
| Polycrystalline panels | Rs. 9,800to Rs. 11,220 |
| Bifacial panels | Rs. 15500/unit |
