CW ENERJI MUH. TIC. VE SAN. A.S., established in 2010, is a leading manufacturer, solution provider and service company in the photovoltaic power generation sector. CW Enerji’s scope of products comprises solar power plant investment and technical consulting, projecting, system design, solar power plant installations, licensing and operation, as well as licensed and unlicensed production regulations for solar power plants projects planning, designing, financing, implementation and general maintenance matters.
DARK/Black Once the silicon crystals are manufactured, they are adhered to a backsheet that arranges them into a grid pattern. This backsheet can be seen through the gaps between the cells, and impacts the overall appearance of the panel.
Regardless of actual performance differences, you bring up a great point with regards to service life. If black backed panels do reach slightly higher temperatures on a daily basis compared to white backed panels, will it have a notable effect on longevity? Will they break down at a faster rate? Granted, they are still backed by the standard 25 year / 80% warranty, but could black backing account for some additional degradation? Are black backed panels more readily available because nobody wants them in my region?
“When white backsheets are used, the empty spaces or gaps between and around the solar cells provide a reflection of the unused light and increase the likelihood of ‘light trapping,’ resulting in an increased generation of photocurrent,” said Geoff Atkins, executive advisor of North American panel manufacturer Silfab Solar. “All-black modules have a more aesthetically pleasing look but lose the benefit of reflection and light trapping, resulting in a lower photocurrent — up to 3% less than a white-backsheet module. Three percent less current means about 0.5% lower absolute efficiency.”
Black backsheets create a more uniform look to the solar panel, which helps it blend in with darker roof materials. However, the black color does hold some heat, so black backsheets may get hotter than traditional white backsheets. That said, the tradeoff in efficiency may be worth it for a more visually appealing solar installation.
The 210mm silicon wafer is too large, and the weight of the 108 cells 210mm module has also increased significantly, which will bring load risks. At the same time, the width and length of the module will increase accordingly, and auxiliary materials such as glass and frames cannot meet the supply.
Tommatech is the solar energy panel brand produced by CW Energy in Domestic Antalya. In general, Off-Grid is the product brand it produces for small applications. CW Enerji produces products under the brand name of CW Energy in Professional GES power plant applications. In addition,
CW Energy produces low quality products under the Suneng Brand. Torges There are non-guaranteed economic and non-certified contract products that do not include the CW name on the brand.CW Enerji Mühendislik Ticaret ve Sanayi Anonim Şirketi is a production and service company operating in the photovoltaic power generation sector, established in 2010. It is one of the solar panel manufacturing companies with an annual solar panel production capacity of 1.8 GW.
Tommatech/CW is also known as the Alamn brand in the industry, with the words Germany Design (Alamn Design), Germany Based Company (German firm) written on its products. However, only the registration of the trademark was made in Germany, other than that, this product is not produced or sold in Germany. Our customers who bought the productWe want them to know that it is not a German brand.
Advantages of Tommatech/CW Solar Panels and Why to buy
- It is one of Turkey's Top 5 Solar Panel Manufacturers.
-There is a dealer and sales network all over Turkey.-There is a fast and corporate understanding of warranty and service.-It is the most known brand in Turkey.
- It supplies and sells all products in Solar Energy systems such as panels, inverters, batteries, drivers. Offers complete solutions
- Cosmetically and visually, the products are manufactured with great care.-Providing training service, Having personnel with technical grandfather-Having International Certificates
-15 Years Physical Warranty, 30 Years Performance Warranty.-The frame thickness is 40mm, and it is manufactured more durable than many other manufacturers.Disadvantage of Tommatech/CW Solar Panels
- Heat Performance Pmax coefficient is slightly higher than other manufacturers. So the performance drops as it gets hotter.is more -0.36%/ºC
- Their prices are around 20%-30% more expensive than other equivalent manufacturers with the same electrical values, lifetime and warranty.
-Tommatech Solar panel economically have longer amortization periods.
-Selling a product with the perception that it is made in Germany, although it is not a German product.
Moreover, while Turkey has become the world's most important production center with its nearly 60 factories, the unjustified advertisement of Germany does not coincide with our national interests.
-Since sales are not made with a single brand (CW, Tommatech, Suneng, Torges), it is very difficult for the customer to make a choice by making technical comparisons.
-The technical difference between Tommatech and CW is not disclosed and the two are sold at different prices; forcing customers to choose expensive is better in sales marketing.
-We cannot see additional superior features from other brands in datasheets and test reports.
All processes that require high precision in Tommatech's modern production line are carried out with robotic systems.
HandCW solar panels produced without touching, efficiency, longevity and durabilityadvantage in terms of Making domestic production using German technology,
-class quality.There are more than 50 manufacturers in Turkey.
All of them have been in operation for almost the last 5 years.
Almost all of the manufacturers use the same Glass from Şişecam, Cell from China, Back Sheet and EVA from the same product group.
The production processes are the same. There is almost no difference. We share these small differences with you on our site.
