If you want maximum powering up your system, then go with 400-watt solar panels as they are more efficient than 100-watt ones. 400-watt solar panels can be used to power up larger appliances like washing machines, fridges or air conditioners.
A 400-watt solar panel can run many different appliances. There are types of appliances that require less energy than others, though not all appliances list the required electricity (watts). In this article, we will learn everything you need to know about 400-watt solar panels and if it is the right one for your house according to your needs.
Composition of a Solar Panel
A solar panel consists of photovoltaic cells. These cells are responsible for turning sunlight into electricity. When enough sunlight is collected by these cells, an electric field is created which can be used to power up inverters or electronic appliances. The number of photovoltaic cells in a solar panel varies depending on the wattage. A 100-watt solar panel uses 100 cells whereas a 400-watt solar panel has around 160-170 cells (typically 180 cells). Since it has more cells, a 400-watt solar panel system is more efficient than a 100 watt one.
How many watts of energy do you need?
Wattage reflects the amount of power that will be generated by your solar setup. The more wattage you have, the more appliances you can run at a time at the same voltage or sell the excess energy to a utility company. However, before buying any wattage you must measure how much energy your household consumes daily so that it gives you an idea of how many watts are required for powering it! Once you have figured out the watts required for your house, it is easy to choose between 100 watts and 400 watts solar panels. If you want maximum powering up your system, then go with 400-watt solar panels as they are more efficient than 100-watt ones. 400-watt solar panels can be used to power up larger appliances like washing machines, fridges or air conditioners. Before going into that let's learn more about the different types of solar panels that are available in the market.
Different Types of Solar Panels
Monocrystalline These are the most commonly used ones in the market. They are made by creating silicon wafers in a very refined process and hence generate higher voltage than other types, that is, around 16 volts.
Polycrystalline These are made up of purified silicon and generate an average voltage that ranges from 13.5-14.5 volts.
Thin film These are the cheapest ones in the market given that they do not contain any silicon and has an average voltage of 12 volt. depending on your need, you can choose among these types of solar panel for your solar power system. Monocrystalline are the best suited for the generation of solar power but if there's no need for a 400-watt solar panel and if high voltage is not important, thin film is a great option.

What is the watt range for homes? Now that you know everything you need to know before choosing a 400-watt solar panel, it's time for some math! You need to calculate how much energy your home consumes daily by adding up all your appliances together (include air conditioner, fridge, etc). Now take this number and divide it by the number of hours the appliance runs. For example- let us say that your home consumes 2000 watt hours per day and you run an AC for 8 hours. This means that you require around 250 watts per hour (2000/8) for your AC to function properly. If you want to power other appliances like your TV, lights etc, you should add up all individual appliance's watt hours and take the total. 400 watts is a pretty decent number so you can power up most of your appliances at once without overworking them. If you are using LED lights, they consume less wattage than regular ones so it is advisable to use those to reduce the number even further! If you are planning on having 2 or more solar panels installed for powering up your home, 400 watts should suffice for daily use. However, if there are too many appliances running at the same time then your batteries might run out of energy faster so keep that in mind!
Specifications of 400-watt solar panels Size of 400w solar panels: usually around 39 inches by 21.5 inches Weight of 400w solar panel: between 24 to 31 pounds Rated power output capacity: 400 watts Number of solar cells in a panel: 60 Output wire 1: 12 volt DC positive and negative wires, one set each (also known as PV wire) Output wire 2: grounding wire for earth ground connection to the incoming household electrical service grounding conductor or an extension cord with a ground wire to connect to separate earth ground such as a grounded outlet box containing a properly installed receptacle that is not likely to be disconnected from the box and supply wiring, which is typically located at or near where the main entrance cable enters the building or structure. A homeowner will be distributing the demand for electricity through multiple appliances. It is inevitable that some appliances require more energy than others, thus resulting in power depletion for each appliance if the electric current is supplied from one solar panel. Solar panels do not have an intelligent mobile chip, so homeowners need to consider how to use them efficiently. They can choose between two techniques: using multiple small-sized solar panels or using one large-sized powerful solar panel. The second alternative has its own merits and demerits which will be discussed below. One 400 watt mono-crystalline can produce enough electricity for most appliances available in homes including the following: Refrigerators Washing Machine Iron box Benefits of 400 watt monocrystalline solar panels High conversion efficiency with low environmental impact Mono-crystalline solar panel is a kind of high performance solar panel. It can convert about 20% of sunlight into electricity in a year, while the polycrystalline one only converts 17%. In addition, the monocrystalline solar panel contains no hazardous materials such as lead and mercury. This type of panel has a little environmental impact. It is recyclable when homeowners decide to change it for better ones in future. Longer lifespan Mono-crystalline solar is known for its long lifespan which facilitates providing electricity from it for about 25 years. Relatively low cost of installation Monocrystalline solar panels are more expensive, but it is worth spending more money on them because they provide better electricity yield in the long run. Even if homeowners choose to buy used ones, their service life would be longer than most other types of solar panels. One 400 watts monocrystalline solar panel usually costs around $160 - 190 each, according to different models and suppliers available online at eBay or Amazon. The unit price for this type of panel might be further lower by bulk purchases from China manufacturers, which are trying to sell them with prices starting from $100 per piece these days. On the contrary, polycrystalline panels have a relatively short lifespan of about 10 years, which is not suitable for using to power most appliances. Drawbacks of 400 watt monocrystalline solar panels Monocrystalline panels are not a good choice for powering small devices such as mobile phone chargers because they could only supply currents 1/5 or less than what a charger needs. The demerits of this type of solar panel include the following: High cost per watt-hour produced One 400 w unit costs too much to obtain a small number of watts per hour. For instance, homeowners would need to spend $160 - $190 to get about 30 -50 watts from it every hour depending on the condition and performance of their panels. It simply does not worth the money. The price per watt-hour produced is at least 5 times higher than that of a monocrystalline panel. Even if homeowners need to pay $120 - $150 for a 400 w mono panel, its charge controller and installation works would cost more than $500 which means they could easily buy 50-watt poly panels and save some money. No room for expansion Another drawback of the monocrystalline solar panels lies in their limited power output compared with other types such as polycrystalline or thin film panels that can provide up to 200 - 300 watts per hour on an average. It simply does not worth it to be spent so much money on them only sufficient enough to power appliances such as washing machines and refrigerators, while they cannot even work to power a television or other electronic devices.
