With the rise of product such as glass, the manufacturing of solar panels has reached a crisis situation and have called developpers to delay their projects.
Several major manufacturers from Asia in an open letter have warned that not only the cost of glass, but also logisitic cost and the soaring of other materials was affecting seriously their production, and endangering the development of their business.
It’s more than 20% increase year to year for the polysilicon price since the Chinese goverment decided to shut down several silicon refineries in the middle of a power crisis.
In this situation non vertically integrated module manufacturers have been heavily hit by shortage of raw material needed
Furthermore, with shortages of materials such as copper and silver, pressure on margins remains high for everyone and would inevitably lead to increase in prices of modules
One of the recent Rystad Energy analysis approach to meet the 1.5 degrees 2050 scenario would require to quadruple current manufacturing capacity to reach 1300 GW by 2035. In the short to medium term it is looking extremely challeging to keep costs down after decades of contractions of prices. Prices of panels which have started to increase in 2021 will most probably continue in the coming years. This may put at risk the scenario of production increas and push the development of other ‘clean’ energies
