Best Solar Panel Brands: Which One You Should Choose?
Let’s explore some useful tips to choose the best solar panel system for your home for maximizing ROI and shorter payback period. Also, we will suggest some top solar brands for your assistance.
What factors should you consider before buying solar panels?
Solar Panel Performance:
The efficiency and expected overall performance of solar panels are vital considerations. Higher efficiency panels generate more electricity, making them suitable for limited space, like on a small roof or garage. However, they are often more expensive. Choosing the top-rated solar panels for your needs includes balancing the efficiency of the panels with their cost-effectiveness and your available space.
Panel Lifespan:
The durability of solar panels is essential for ensuring a long and reliable lifespan. The lifespan of a solar panel is based on the materials used and the manufacturing quality. Look for solar panels with sturdy frames and durable tempered glass that can withstand harsh weather and reduce potential physical damage.
Manufacturers’ Reputation:
Assessing the overall quality of solar panels includes considering the solar panel brand and the panel’s certifications. The best solar panel company commits to higher quality standards. Additionally, solar panels with certifications like IEC (International Electrotechnical Commission) and UL (Underwriters Laboratories) indicate that they meet specific safety and performance criteria.
Solar Panel Technical Specifications:
Understanding the technical specifications of solar panels reflects the wattage, voltage, and current flow. Wattage is the power output of a panel, while voltage and current impact the overall system design. A trusted local solar installer can assist you with all of these factors and can explain the benefits and cons of different wattage and voltage combinations.
Solar Warranties:
Solar panel warranties assure potential defects and performance issues. There are typically two types of warranties: product warranties and performance warranties. Product warranties cover manufacturing defects and generally range from 10 to 25 years. Whereas, Performance warranties guarantee a certain level of power output over a specified period, usually 25 to 30 years. Opt for panels with longer and leading warranties to ensure the longevity of your investment.
What are the best solar panels for your home?
Type of Solar Panels:
There are three main types of solar panels available in the market: monocrystalline, polycrystalline, and thin-film. Monocrystalline panels are known for their high efficiency and sleek design. They are often more expensive but offer better performance in limited space. Polycrystalline panels are cost-effective but slightly less efficient. Thin-film panels are lightweight and flexible, making them suitable for specific applications, and are often a little less efficient than silicon solar panels but they’re also less expensive, making them ideal for larger installations.
TIP: Choose the type according to your space availability, budget, and aesthetic preferences.
Power Output Rating
The power output rating of a solar panel is measured in watts (W). It indicates how much electricity the panel can produce under standard test conditions. Higher-watt solar panels produce more electricity.
TIP: Choose a system that balances power output with available roof space. For a limited installation area, you may need to choose higher-wattage panels.
Efficiency Rating
Solar panel efficiency is a vital factor in determining how much energy a panel can produce. Higher efficiency percentages indicate better energy conversion performance. Monocrystalline panels generally are more efficient than polycrystalline ones.
TIP: Higher-efficiency panels are beneficial if you have limited space or want to maximize energy production from your installation.
Temperature Coefficient
The temperature coefficient measures how much a solar panel’s efficiency decreases as temperatures rise. Solar panels are more efficient in cooler temperatures, and a lower temperature coefficient indicates better performance in high temperatures.
TIP: When choosing solar panels, consider the average temperatures in your location to ensure the panels can maintain efficiency during hot weather conditions.
