Efficiency: Getting the Most Out of Your Panels

Solar panel efficiency measures how well a panel converts sunlight into usable electricity. Higher efficiency means more energy output from the same amount of sunlight.

  • SunPower: Known for high efficiency, SunPower panels often rate above 22%, making them a top choice for those with limited roof space.
  • LG: Offering efficiency rates around 20-22%, LG panels are both reliable and efficient.
  • Panasonic: With efficiency rates close to 20%, Panasonic provides a balanced solution of performance and price.

When deciding on efficiency, consider your roof space and energy needs. Higher efficiency panels can deliver more electricity, which might justify a higher upfront cost.

Durability: Longevity and Warranty

The durability of solar panels is another critical consideration. You want panels that will withstand various weather conditions and last for decades.

Ensure you check the warranty details of each brand, as this can significantly impact the overall value of your investment.

Cost: Balancing Budget and Quality

While some may prioritize efficiency, others might focus on the cost. Solar panel pricing varies significantly based on brand, efficiency, and installation costs.
