A solar panel is a device that converts sunlight into electricity using photovoltaic (PV) cells. These cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries. Solar panels are also known as solar cell panels, solar electric panels, or PV modules.
Solar panels are usually arranged in groups called arrays or systems. A photovoltaic system consists of one or more solar panels, an inverter that converts DC electricity to alternating current (AC) electricity, and sometimes other components such as controllers, meters, and trackers. Most panels are in solar farms, which supply the electricity grid as can some rooftop solar.

Conclusion:
Choosing and buying solar panels involves understanding your needs and the different aspects of the panels themselves. Here’s a breakdown of the key factors to consider:
Understanding your needs:
- Energy consumption: Assess your household’s electricity use to size the solar panel system accordingly. This will determine how many panels you’ll need.
- Roof characteristics: Evaluate your roof size, angle, and shading. South-facing roofs with minimal shade are ideal for solar panels.
Solar panel factors:
- Output and Efficiency: Higher wattage (Wp) means more electricity generation, but efficiency (percentage of sunlight converted to electricity) is also crucial. More efficient panels require less space to produce the same power.
- Type of material: Monocrystalline panels are generally more efficient but pricier than polycrystalline panels. There are also newer technologies like bifacial panels that capture sunlight from both sides, potentially increasing efficiency.
- Warranty: A good warranty (typically 25 years) ensures protection against power degradation and manufacturing defects.
- Cost vs. value: Balance the upfront cost with long-term savings and consider factors like efficiency and warranty when evaluating the value proposition.
Additional considerations:
- Brand reputation: Research the brand’s reputation for quality and customer service.
- Aesthetics: Solar panels come in different colors and sizes. Consider how they’ll impact your roof’s appearance.
After choosing your panels:
- Get quotes from several qualified solar installers.
- Look for certifications and licensing to ensure quality installation.
