What Need to Look for When Buying Solar Panels
Installing the best solar panels will provide you with adequate energy and efficient solar panels to ensure long-term service with the value of money.
Before selecting a solar panel, you have to consider some key features to understand the specifications and production capacity of the solar panel.
Best solar panels go through quality control manufacturing and contain the latest technology.
To find the best solar panels, you must specify the quality with some essential matters.
The best product comes from the best manufacturer, and it applies to solar panels too. If you select a solar panel manufacturer with years of experience and the latest technology, you will get the best product.
Leading solar panels manufacturers try to enhance their service for the global competition, and they are offering a reasonable price.
Before purchasing your next solar panels, you have to consider the brand. It will ensure an efficient product for this renewable energy system.
Besides, leading brands have a wide supply chain to provide one-stop solar panel delivery.
They will offer you the best installation facilities if you ask for the installation.
Solar panels will absorb sunlight and produce electricity. The system will generate adequate power for your home, office, or business if you have efficient solar panels.
Besides, you have been installing solar panels for a long time. It will last for 25 to 30 years. That is why efficiency is important. Without powerful solar panels, you can not get energy for a long time.
For example, if you have installed solar panels with the highest degradation rate, it will never be fruitful for 30 years.
Inefficient solar panels will just use your rooftop without producing sufficient energy. So, consider this fact before installing solar panels.
Solar Panel Type
Imagine installing solar panels without any idea of solar panel types. It will be a crucial mistake for you as a homeowner.
If you don’t have any idea about solar panel types, an installer can provide the least efficient solar panels at the highest price.
On the contrary, if you know solar panel classification facts, you can ask the manufacturer for the best type.
Similarly, each type has an individual efficiency rate of energy production. You have to find a suitable type for your solar energy solution.
Monocrystalline, polycrystalline, and thin-film solar panels are the most used types in the solar industry.
Solar Cell Technology
Global manufacturers are producing solar cells with the latest technology. Hybrid solar panels are more efficient than traditional solar panels.
Besides, companies try to develop new solar cells with a combination of previous technologies and types.
As a renewable energy consumer, you have to consider solar panels with the latest technology. It will enhance the solar system’s efficiency and allow you to get more power with the same space.
For example, in the above section, we present the Sunpower X22 and Panasonic N325 that come with the latest solar technology and produce more energy.
Power degradation represents the efficiency loss of the solar panel per year. It will reduce the production rate every year with a minimum percentage of the total efficiency of the solar panel.
On the other hand, normal solar panels will be unable to perform in the long run, and their degradation rate is higher than quality solar panels.
Before installing solar panels for your energy solutions, you must understand the fact before installing solar panels. Otherwise, your primary investment will be a loss project.
Installation and Manufacturing Process
You have selected your solar panels to install, but have you thought about the installation? You can’t install solar panels at home.
It will never be professional if you want to follow the DIY process. Solar panels are the most important parts of a solar system.
Solar panels require professional installation and an accurate mounting option. For example, you don’t know that solar panels must be installed facing south.
If you install it in the other direction, it can not get sunlight for the whole day. So, it is better to install solar panels by professionals.
On the contrary, the manufacturing process is also important because only proper manufacturing can ensure the best cells.
Size of the solar panel
Solar panels need space to mount for getting sunlight. You can install solar panels on the rooftop or the ground. Consumers like to install solar panels on the rooftop because they will utilize the space above.
So, you have to select efficient solar panels that will take less space and produce more energy. For example, Panasonic solar panels will save 60 percent space with high-efficient solar panels.
You can compare the size of a solar panel regarding its cells and wattage. In general, a traditional solar panel comes with 65 inches in height and 39 inches wide.
The value of money is a significant part of solar panels that you can’t ignore. You are going solar because you want to save your electricity costs.
If the solar panels do not have the perfect price compared to the efficiency, it is difficult to get sufficient energy from the system.
Similarly, grid-tied and off-grid solar systems have different requirements. After installing a solar system, it is not worth paying thousands of electricity bills.
So, try to find out the best solar panels for your renewable energy solution. Panasonic and Sunpower have several models to ensure your energy production rate.
For solar products warranty provides your after-sales service and ensures the repair in case of any damage. Besides, there are other maintenance issues that you will get from the manufacturer and supplier.
You should install the solar panels that come with wide warranty coverage and provide you with potential customer support.
The warranty for solar panels is divided into two sections, solar panels physical warranty and solar panels energy production warranty.
The first one deals with the manufacturing fault or any physical damages, and the second one deals with the efficiency of the solar panels.
