The Basics of Solar Panels

Solar panels serve as a component in energy systems, capturing sunlight and converting it into usable electricity. When sunlight interacts with these cells, it energizes the material’s electrons, generating a direct (DC) current.

At the core of each panel are photovoltaic cells, referred to as cells, which are constructed using semiconductor materials like silicon. Typically solar panels are grouped in what’s called an array. These arrays consist of panels arranged in series or parallel configurations to generate the desired voltage and current.

Type of PanelsWhat Do They Mean?
MonocrystallineMonocrystalline solar panels have an advantage in appearance due to their crystal structure, resulting in a sleek and uniform look. Moreover, they possess an efficiency that enables them to generate electricity per square foot compared to alternative panels.
PolycrystallinePolycrystalline solar panels are produced using crystal structures resulting in a consistent appearance characterized by a bluish tint. Although their efficiency is slightly lower than other panels, they are generally more budget-friendly.
Thin-FilmThin-film solar panels are created by applying layers of photovoltaic material onto a base material such as glass or flexible substances. Compared to crystalline panels, thin-film panels generally have efficiency, implying that they may require more surface area to generate an equivalent amount of electricity.
BifacialBifacial solar panels can generate electricity from both sides of the panel, capturing sunlight on both the front and rear surfaces. It makes them more efficient than monofacial panels, as they can generate more electricity from the same amount of sunlight, leading to higher energy yields and better system performance.

Factors Influencing Solar Panel Performance

FactorsWhat Do They Mean?
EfficiencyEfficiency refers to how the solar panel converts sunlight into electricity. Panels with efficiency can generate power using the same amount of sunlight.
Durability and LongevityDurability and longevity determine the performance and return on investment of solar panels. High-quality panels are designed to withstand weather conditions, ensuring electricity production over time.
Temperature CoefficientsTemperature coefficients indicate how a panel's performance is affected by changes in temperature. Lower coefficients are preferable in climates as they help maintain optimal efficiency levels.
Shading and ObstructionsPartial shading can have an impact on the output of solar panels. It is important to avoid any shadows or obstructions to maximize energy production.
Dust and DirtAccumulation of dust and dirt on panels can decrease their efficiency. Regular cleaning is necessary to maintain performance.

Considerations When Choosing Solar Panels

  • Energy Needs and Goals

Start by assessing your energy consumption and setting your goals for energy. It’s important to understand how much electricity you need so that you can choose the solar panel capacity to meet your requirements and potentially reduce your energy usage.

  • Available Space

Next, evaluate the space to install panels on rooftops, open areas, or ground mounts. Based on your space, you can select types and sizes of panels to optimize energy production.

  • Local Climate and Conditions

Also, consider the irradiance in your region, weather patterns, and any potential shading from trees or nearby buildings. For climates, choosing panels with efficiency and better temperature coefficients is recommended. In areas with weather conditions, durability is crucial.

  • Budget and Cost-effectiveness

Furthermore, consider your budget for the panel system, including installation costs and additional components like inverters and mounting equipment. It’s essential to strike a balance between the investment and the expected energy savings over the panels’ lifespan.

  • Warranty Period

When selecting solar panels, the warranty is important. Solar panels can last 25 years or more, and a good warranty means your panels will keep making power for a long time. It helps if something goes wrong and shows the company believes in its product. Further, a good warranty saves you money on repairs and replacements.
