One factor influencing the dimensions of solar panels is the efficiency of the photovoltaic (PV) cells they contain. Monocrystalline panels are known for their higher efficiency rates, averaging around 15-22%. This means they can produce more electricity in a smaller area when compared to polycrystalline panels, which usually range from 13% to 16% in efficiency. As a result, households with limited roof space might prefer monocrystalline panels despite their generally higher cost.

Another compelling benefit of solar energy is the increased energy independence it provides. With solar panels, homeowners can generate their own electricity, reducing their reliance on external energy providers and the fluctuating costs associated with traditional energy sources. As global energy prices rise, having solar energy can provide peace of mind and stability, allowing homeowners to rely less on a centralized power grid prone to disruptions and price hikes.
