olarWorld USA, a subsidiary of German SolarWorld AG, has been in the solar panel manufacturing business since 1975 and is located in Hillsboro, Oregon. With a long history of being a top player in the solar industry, the company is recognized for its dedication to producing top-quality solar panels.
SolarWorld: A leading solar panel manufacturer
Unlike other solar manufacturers who only do limited assembly in the United States, SolarWorld USA is fully integrated in the U.S., from growing the crystals to cutting the wafers to processing the solar cells and assembling the panels. This gives them complete control over their products’ quality, ensuring they are always of the best standard.
Moreover, SolarWorld has established a large network of local solar installers across the United States, making it convenient for customers to get their hands on their products and services. They also place great importance on building and preserving their brand, investing heavily in marketing and promotion to maintain their position as a leading name in the industry.
A brief overview of Sunmodule Plus solar panels
Right now, SolarWorld has a selection of solar panels that can be used for both commercial and residential purposes. The company offers two main options, the Sunmodule Plus and the Sunmodule Plus Black.
Sunmodule Plus is the company’s most popular product. It's ideal for various types of residential settings, such as pitched or flat roofs or ground-mounted installations. On the other hand, the Plus Black option provides the same benefits as the previous model but with the added benefit of a sleek and stylish black design.
Sunmodule solar panels come in sizes up to 300 watts and have an average efficiency of 18.3% from their 300w panel. This is above average compared to other tier 2 and tier 3 alternatives but not as high as the top brands like Sunpower and LG. The panels also have a temperature coefficient of -0.39%, meaning output decreases by 0.39% for every degree increase in temperature. Although not the best on the market, it's better than many other brands in the same price range.
SolarWorld offers a robust warranty package with a 20-year structural warranty, the longest of any tier 1 solar manufacturer. Their power production warranty also provides peace of mind, with 97% output guaranteed in the first year and a linear degradation rate of 0.5% per year. This means they guarantee 92.5% output after ten years and over 82.5% after 25 years, which is similar to top brands like Sunpower and Panasonic.
Evaluating the feasibility of Sunmodule solar panels for your solar system
To sum up, Sunmodule solar panels are an excellent choice for homeowners who prioritize American-made products and the support of local installers. Known for their high quality and durability, these solar panels come with an outstanding 25-year linear power output warranty, one of the best in the market.
While they may not be the most efficient or handle high temperatures, as well as others, they still provide a trustworthy solar solution. Ultimately, the decision to use Sunmodule should be based on the homeowner's specific requirements and preferences.
