    FAQs about Benefits of photovoltaic double-glass modules

    Why should you choose glass in a PV module?

    The choice of glass in a PV module has become a key consideration in efforts to improve durability in the face of extreme weather conditions.

    What is a dual-glass module?

    Dual-glass type modules (also called double glass or glass-glass) are made up of two glass surfaces, on the front and on the rear with a thickness of 2.0 mm each. Some manufacturers, in order to reduce the weight of the modules, have opted for a thickness of 1.6 mm. DualSun has chosen to stay with a thickness of 2.0 mm for reasons explained below.

    Why are double glass modules symmetrical?

    Mechanical constraints on cells: the fact that the structure of the double glass modules is symmetrical implies that the cells are located on a so-called neutral line, the upper part of the module being in compression during a downward mechanical load and the lower glass surface being in tension.

    Can tempered glass be used in solar modules?

    The only feasible way for tempered glass to be widely used in solar modules is its application in single-glass modules. The prevailing benchmark for hail resistance, which stipulates that solar modules must be capable of withstanding impacts from hailstones up to 35mm in diameter, may fall short in areas frequently subjected to larger hailstones.

    Do PV modules have tempered glass?

    Among the current module products on the market, only single-glass modules are equipped with tempered glass. The choice of front and shear materials is critical in determining the module's ability to withstand hail impacts. Over the past decade, the PV industry has experienced a great revolution.

    What are the different types of photovoltaic modules?

    Two types of photovoltaic module structures coexist: Glass-polymer film (also called glass-backsheet) type modules. They are made of glass on the front side and polymer film on the rear side.

    FAQs about What drives the price of photovoltaic modules

    How does the price of photovoltaic (PV) modules affect costs?

    The price of photovoltaic (PV) modules, which has declined significantly due to technological advancements and economies of scale, remains a major component. However, fluctuations in raw material costs, such as silicon, can still impact overall expenses, requiring careful market analysis and procurement strategies.

    Why do solar modules cost so much?

    However, as the primary cost component of photovoltaic modules, the price of solar cells plays a decisive role in module pricing. Due to the oversupply of polysilicon in earlier periods, prices have been under sustained pressure since 2023, even falling below cost levels in the first half of 2024.

    Why do PV modules cost more than underlying production costs?

    As described above, these more recent changes have been associated with changes in the structure of the PV supply and manufacturing industry, thus affecting PV module prices more than underlying production costs.

    How much does a solar module cost?

    For example, in March 2012 average retail module prices were respectively 2.29$/Wp in USA and 2.17€/Wp in Europe, but the lowest retail price for a crystalline silicon solar module was 1.1$/Wp (0.81€/Wp) and the lowest thin film module price was 0.84$/Wp (0.62€/Wp).

    How are photovoltaic module price adjustments affecting industry players?

    The current round of photovoltaic module price adjustments has imposed significant operational pressure on industry players. Leading companies, with their high R&D costs, are at a disadvantage in the price competition. Meanwhile, small and medium-sized enterprises find it challenging to endure prolonged price wars.

    What factors affect the cost of developing solar energy projects?

    The cost of developing solar energy projects is shaped by several factors. The price of photovoltaic (PV) modules, which has declined significantly due to technological advancements and economies of scale, remains a major component.
