Five Key Factors to Use Solar Panels

Many builders nowadays incorporate solar panels in their projects due to the increasing popularity of solar energy. As a construction professional, it’s crucial to have a basic understanding of solar panel specifications. To assist you in designing, estimating, or installing solar energy systems in your building projects, here’s a helpful guide.

1. Type of Solar Panel

The solar cell design of the solar panel is a critical specification. Two primary solar cell types exist. Mono solar cells have a single crystal structure, allowing them to convert more light into power than poly panels. Poly panels, on the other hand, have multiple crystals that can reflect sunlight, lowering their efficiency.

2. Wattage and Area Size

The wattage of a solar panel determines its power output and affects how much energy it can generate. Matching a solar panel’s wattage to your building’s power requirements or a solar array ensures constant and adequate power generation throughout the day. The area, measured in square feet, determines the size of solar panels, affecting how easily they integrate into a roof design and the number required to meet your energy needs. The efficiency of the solar cells also impacts the amount of power each produces.

3. Age and Efficiency

When considering using secondhand solar panels to reduce costs, it’s essential to take note of their age and how it affects their warranty and efficiency. Additionally, it’s crucial to determine if the warranty is transferable. While most solar panels have a 25-year warranty, their efficiency decreases over time. To ensure the best return on investment over time, it’s necessary to factor this into your design.

4. Weight and Mounting

Weight is a significant factor to consider when looking at solar panel specifications. It affects the ease of installation, and some manufacturers offer lightweight options that are easier to handle but cost more per unit. Consider using heavier solar panels if you’re trying to save on installation costs. Furthermore, solar panel manufacturers offer various mounting systems, with the strength of panels being crucial for wind and snow loads. Select a solar panel that can withstand local weather and climate conditions.

5. Operating Temperatures and Durability

Operating temperature is another vital consideration, as solar panels perform best when warm but not hot. Manufacturers rate their products based on operating temperature, with most panels operating within a reasonable efficiency range at high temperatures. Additionally, solar panels have a maximum temperature rating for durability, with the temperature coefficient being crucial for areas with high temperatures or quickly heating roofs.
