TongWei solar panels
One of the world's largest solar makers, from polysilicon to finished N-type (TNC) panels.
About TongWei
Tongwei is a Chengdu-based solar manufacturer that covers the whole chain: high-purity polysilicon, wafers, cells, finished modules and the building of solar power plants. It entered the solar industry in 2006.
Its flagship panels are the TNC (Tongwei N-type Cell) series. N-type is a newer cell design that is generally favoured for higher efficiency and slower loss of output over time.
What a solar panel does
A solar panel is made of solar cells that produce direct current (DC) electricity when sunlight hits them. The inverter then converts that power for your home or business.
Panels are rated in watts. A system is built from enough panels to cover the electricity you want to produce, as far as your roof or land allows. Panels lose a little output slowly over the years, which is why the long-term performance rating on a datasheet matters.
What we look at when choosing
- How much usable roof space you have, and which way it faces
- Shading from trees, buildings or roof structures during the day
- How much of your electricity use you want the panels to cover
- The panel's size and weight, and that your roof can carry and mount it safely
