Inverters: Solar inverters play a pivotal role by converting direct current (DC) generated by solar panels into alternating current (AC), which is compatible with household and commercial energy systems. There are different types of inverters available, including string inverters, microinverters, and power optimizers. Each type has distinct advantages and is chosen based on the system’s specific requirements to maximize energy output and efficiency.

3. HOW SOLAR ENERGY IS GENERATED

The generation of solar energy involves multiple stages that transform solar radiation into electrical power. An in-depth examination of this process reveals its complexity and efficiency.

Photovoltaic Effect: The photovoltaic effect is the mechanism that entraps sunlight within solar cells to generate electricity. When photons collide with the semiconductor material in the cells, they excite electrons, which then flow through the material, creating an electric current. The efficiency of this process varies depending on the type of semiconductor used, with monocrystalline and polycrystalline silicon being the most common materials.

Energy Storage Systems: Energy generated through solar panels can be directly used during daylight hours, but to ensure a continuous power supply, it is essential to store excess energy. This is where energy storage solutions come into play. Solar batteries are commonly deployed to store surplus electricity, allowing it to be accessed when solar production declines or is non-existent, such as during nighttime or cloudy conditions. Understanding storage options is fundamental for maximizing the utility of solar energy.
