This project is a key collaboration between ACWA Power and the Uzbekistan Ministry of Energy, which includes a 200MW photovoltaic and 500MWh energy storage system.
Instead of using thick layers of crystalline silicon, thin-film solar cells are made by depositing one or more thin layers of photovoltaic material onto a substrate. These layers are incredibly thin - often just a few micrometers thick, which is about 100 times thinner.
In order to meet international renewable energy goals, the worldwide solar capacity must increase significantly. For example, to keep up with the goal of 4674 GW of solar capacity installed globally by 2050, significant expansion is required from the 1185 GW installed globally as of 2022. As thin-film solar cells have become more efficient and commercially viable, it has become clear that they will play an important role in meeting these goals. As such, it's become increasingly imp.
A 9kW solar system in Georgia costs around $18,900 after the 30% federal tax credit and saves approximately $1,776 per year on electricity at the state's average rate of 13¢/kWh.
Thin-film solar panels are made from a variety of materials, depending on the specific technology. The most common types of thin-film panels are cadmium telluride (CdTe), amorphous silicon (a-Si), and copper indium gallium selenide (CIGS).
The main difference between the two technologies is the type of silicon solar cell they use: monocrystalline solar panels have solar cells made from a single silicon crystal.
Panel prices have dropped over 50% since 2018, making solar economically viable across most of the country for the first time. A 3 kW system (7-8 panels, 400W each) costs NZ$6,500-9,000 installed. Suitable for smaller households or as a starter system.
