Another consideration is the weight of the solar panel system. Slate roofs must be able to support the additional weight of solar panels, mounting hardware, and the associated equipment. It's essential to consult with a structural engineer to assess the roof’s load-bearing capacity before proceeding with installation.
Furthermore, market conditions play a pivotal role in determining the price of solar panels. Supply chain disruptions, fluctuations in manufacturing costs, and changes in government subsidies or tariffs can lead to price variations. Recent trends have shown that as the demand for solar energy increases, prices have started to stabilize after a period of fluctuation.
2. Technology Different solar technologies, such as monocrystalline, polycrystalline, and thin-film solar panels, influence pricing. Monocrystalline panels, which are often used in 440W systems, tend to be more expensive due to their higher efficiency and aesthetics.
