Q1: How long do solar panels last?

Solar panels typically have a lifespan of 25 to 30 years, with many manufacturers offering warranties for this duration. Regular maintenance ensures optimal performance over the years.

Q2: Are higher wattage solar panels better?

Higher wattage panels can be advantageous, as they generate more electricity per unit. However, suitability depends on available space and budget. Efficient placement and quality components also influence overall system performance.

Q3: Are solar panels worth it?

Yes, solar panels are a worthwhile investment. While the initial cost may seem significant, the long-term savings on electricity bills, environmental benefits, and potential incentives make them economically and ecologically viable.

Q4: How many solar panels do I need to run a 5000 square foot house?

The number of panels required depends on factors like location, sunlight exposure, energy consumption, and panel efficiency. On average, a 5000-square-foot house may need a system with a capacity of 15-20 kilowatts, requiring approximately 45-60 standard 300W panels. A professional assessment is recommended for accuracy.

Q5: What environments do 40w solar panels perform best in?

40W solar panels perform best in sunny outdoor environments such as camping, hiking or desert safaris. Their high-efficiency silicon technology ensures maximum charging efficiency in full sunlight.
