700 Watt Solar Panel Prices in Pakistan

1. Conversion Efficiency

• Definition: Conversion efficiency refers to the percentage of sunlight that a solar panel can convert into usable electricity. Higher efficiency panels produce more power per square meter.
• Comparison:
  • Longi 600W Panel: Typically offers around 20-21% efficiency.
  • Jinko 600W Panel: Similar efficiency range of about 20-21%.
  • Canadian 600W Panel: Also within the 20-21% range.

  Panels in the higher capacity ranges (like the hypothetical 700W panel) might push the efficiency slightly higher, possibly up to 22-23%, especially if using advanced cell technology like PERC or N-type cells.

2. Temperature Coefficient

• Definition: The temperature coefficient indicates how much a panel’s efficiency decreases as the temperature increases. A lower temperature coefficient is better as it means the panel loses less efficiency in hot conditions.
• Comparison:
  • Longi Panels: Usually have a temperature coefficient around -0.35%/°C.
  • Jinko Panels: Similar temperature coefficients of around -0.34% to -0.36%/°C.
  • Canadian Panels: Typically around -0.35%/°C.

  If the 700W panel follows this trend, it would likely be in the same range, possibly improving slightly with newer technology.

3. Power Density

• Definition: Power density is the amount of power output per unit area (usually measured in watts per square meter). Higher power density means you get more power from a smaller area.
• Comparison:
  • Longi 600W Panel: Approximately 200W/m².
  • Jinko 600W Panel: Similar to Longi, around 200W/m².
  • Canadian 600W Panel: Slightly lower at about 198W/m².

  A 700W panel would likely push these numbers up, offering a power density closer to 220-230W/m².

4. Degradation Rate

• Definition: The degradation rate indicates how much the panel’s efficiency decreases each year. Lower degradation rates mean longer-lasting panels.
• Comparison:
  • Longi Panels: Typically degrade at a rate of about 0.45% per year.
  • Jinko Panels: Degradation rate is around 0.5% per year.
  • Canadian Panels: Similar to Longi at about 0.45% per year.

  Higher wattage panels, if newer models, might offer improved degradation rates as low as 0.3% to 0.4% per year.

5. Build Quality and Durability

• Considerations: Look at the materials used in the panels, such as the type of glass, the quality of the frame, and resistance to environmental factors like moisture and dust. These factors contribute to overall efficiency and longevity.
• Comparison: All the brands listed (Longi, Jinko, Canadian) are known for high build quality, but newer models may feature enhanced durability, especially in higher wattage options like a 700W panel.

6. Price-to-Performance Ratio

• Definition: This metric evaluates how much efficiency you get per unit of cost. It’s an important consideration for those looking to balance cost and efficiency.
• Comparison:
  • Longi Panels: Generally offer a good balance of price and performance.
  • Jinko Panels: Slightly more affordable but with very competitive efficiency.
  • Canadian Panels: Typically higher priced but with excellent build quality and efficiency.

A hypothetical 700W panel might come at a premium cost but could offer the best price-to-performance ratio due to its higher efficiency and power output, making it a wise investment for those seeking long-term value.

Typical Lifespan of Solar Panels

• Standard Lifespan: Most solar panels are designed to last between 25 to 30 years. This doesn’t mean they stop working after this period, but their ability to generate electricity will gradually decrease.
• Performance Warranty: Manufacturers often provide a performance warranty that guarantees a certain level of efficiency over the lifespan. Typically, a panel will still produce around 80-85% of its original capacity after 25 years.

Factors Affecting Solar Panel Lifespan

1. Degradation Rate:
   • Solar panels degrade over time due to exposure to the elements, leading to a gradual reduction in power output. The average degradation rate is around 0.5% per year.
   • Some newer models, especially those from high-quality brands, have a lower degradation rate of 0.3% to 0.4% per year, extending their effective lifespan.
2. Quality of Materials:
   • High-Quality Materials: Panels made with high-quality materials, such as tempered glass, corrosion-resistant frames, and durable encapsulants, are more likely to last longer and degrade more slowly.
   • Brand and Technology: Brands like Longi, Jinko, and Canadian Solar are known for using advanced technologies and high-quality materials that enhance the durability and lifespan of their panels.
3. Installation Quality:
   • Proper installation is crucial for maximizing the lifespan of solar panels. Poor installation can lead to issues like water ingress, electrical faults, or mechanical damage, all of which can shorten the panel’s lifespan.
4. Environmental Factors:
   • Climate: Panels in harsh climates (extreme heat, cold, or high humidity) may degrade faster, although modern panels are designed to withstand various environmental conditions.
   • Maintenance: Regular cleaning and maintenance, such as removing dust, dirt, and debris, can prevent performance issues and extend the lifespan.

What Happens After 25-30 Years?

• Continued Operation: Solar panels can continue to generate electricity well beyond their expected lifespan, but at a reduced efficiency.
• Replacement: After 25-30 years, you might consider replacing older panels with newer, more efficient models, especially if they no longer meet your energy needs.

Extending the Lifespan of Your Solar Panels

1. Regular Maintenance: Schedule regular inspections and cleaning to ensure your panels are free of debris and operating efficiently.
2. Monitor Performance: Use monitoring systems to track your panels’ performance and detect any issues early.
3. Professional Servicing: Engage professional technicians for repairs or adjustments to prevent long-term damage.
