Factors To Consider Before Buying The Best 375-watt Solar Panel

1. Types Of 375-watt Solar Panels

The different types of 375-watt solar panels are based on two factors- the mounting type, and the technology used. 

a. Mounting Type- There are two ways in which solar panels are mounted or fixed to someplace. Thus, there are fixed solar panels and flexible solar panels. 

1. Fixed Solar Panels- The fixed solar panels are the conventional type of solar panels that have been available in the market for quite some time now. These solar panels are fixed on the rooftop into a corrosion-resistant aluminum frame. An EVA film and a TPT back sheet are used to design the solar panels. 

Fixed solar panels are used for multiple purposes on the utility, commercial, and residential scale and hence, they are commonly found in the market. You can install these solar panels in boats, small cabins, and trailers. 

2. Flexible Solar Panels- With a growth in the demand for portable appliances, the popularity of flexible solar panels became unparalleled. The best 375-watt solar panels are now mostly flexible so that they can be carried from one place to another easily. These solar panels have been designed to be compact and lightweight for this purpose. 

b. Technology

Solar panels across the country are designed based on two technologies- monocrystalline and polycrystalline. 375-watt solar panels are available based on either of these two technologies. 

1. Monocrystalline Solar Panels- These are the more superior-quality solar panels that are not only more efficient, and durable but also more expensive. It has an efficiency rate of 18-25% which is higher than that of polycrystalline solar panels. They have round edges and a dark black look which makes it easy to recognize them. 

As the name suggests, these solar panels are made using a single crystal seed that is turned into a solid crystal structure after placing the seed in molten silicon. A single solar cell is then formed by integrating the sliced silicon wafers. Brands usually offer a 25-year warranty on the panels and they tend to last even longer than this in most cases. 

2. Polycrystalline Solar Panels- If you are looking for a low-cost option while buying solar panels, those made using polycrystalline technology are the ideal ones. The low price does not mean any compromise on quality. Premium-quality materials are used to make polycrystalline solar panels as well. 

However, these solar panels boast a 17-20% efficiency and last for a shorter period as well. Multiple crystals are used to make them and you can easily recognize a polycrystalline solar panel by its blue color. They usually have a lifespan of 25-28 years which is slightly less than that of the monocrystalline solar panels. 

2. Weight

Another crucial factor that must be taken into consideration before buying the best 375-watt solar panel is the weight of the panel. This is important because it directly dictates how portable or heavy the solar panel is. Look for a lightweight and ultra-thin solar panel if you wish to move around the panel frequently and also if the rooftop space is limited.  

Flexible solar panels weigh less than 2 kgs and hence, it’s therefore well suited for being moved around. The less weight of these panels is also advantageous as when there are storms or heavy snowfall as it reduces the chance of any major damage. It also reduces the pressure on the rooftop. 

3. Dimensions

All 375-watt solar panels are designed using the same measurements with slight changes here and there. These dimensions are decided based on the power that the solar panel generates. 375-watt solar panels are medium-sized and the size is ideal for both residential rooftops as well as commercial buildings. However, if you wish to power many appliances at the same time, you will have to connect many such 375-watt solar panels to generate sufficient power. 

4. Price

Before buying the best 375-watt solar panel, you must make sure that you are aware of the price and that it is at par with your budget. Begin by deciding on a set budget for your purchase and try to stay within it. However, do not compromise on the quality of the solar panel just to meet your budget. A cheaper model might look appealing but make sure that it has a 25-year warranty and the service is provided by the brand. 

5. Efficiency

Efficiency is a factor in which you cannot compromise no matter what. Space is usually an issue, especially when you are trying to install it in a residential area. All this considered, every inch of the space available counts and must aid in the generation of power. Moreover, the power generated by a particular module decreases over time, and hence, choosing a low-efficiency solar panel might not be a great idea. 

Look for a solar panel with a high-efficiency that also fits into your budget. This way you can ensure that there is enough electricity for all the appliances in your home or office. 

How To Install a 375-watt Solar Panel?

1. Organize

The most important and the first step in installing a 375-watt solar panel is to organize the space where the modules will be installed. You must first take a close look at the space where the panels will be set up; be it the rooftop of your home or any commercial building. This will help you envision how you might place the solar panels. 

Organize the space before installation or during installation by making sketches and plans so that the solar panels are well-distributed. 

2. Install The Mounting Brackets

The next step in installing the best 375-watt solar panel is the installation of the mounting brackets. It is better to install the mounting brackets while you are still on the ground and before you go to the rooftop. This way you can save on any additional labor expenses. 

3. Install Other Components

This is an important step in the installation process. The other components of a solar system are the charge controller and the battery. These need to be set up in the RV first. Once that has been accomplished, select the shortest path to connect the wires. A longer path will increase the chances of voltage drops as well as increase the power losses. 

4. Drilling and Mounting

Once all the steps have been taken care of, it's time to start with the real work of connecting all the wires and placing the solar panels that were planned. The AWG wires (12-10 AWG) need to be passed through holes that you need to drill. DC breakers must be installed before this and fuses must be installed between the charge controller and the batteries. 

A waterproof cable entry plate needs to be installed on the rooftop and this will be connected to the series or the parallel connection between the solar panels. Next, drill four holes that will hold the modules to the roof and then install each of the panels according to the plan. Bolts and screws will help get this done.
