Frequently Asked Questions (FAQ)
Q: What does the "660 Watt" rating signify for a solar panel?
A: The "660 Watt" rating indicates the panel's peak power output under Standard Test Conditions (STC: 1000 W/m² irradiance, 25°C cell temperature, 1.5 air mass). This is the maximum power the panel can produce under ideal laboratory conditions.
Q: Is a 660W solar panel considered high-efficiency?
A: The efficiency of a 660W panel depends on its cell technology and module design. Generally, monocrystalline panels at this wattage tend to be more efficient than polycrystalline ones. We recommend checking the specific datasheet for precise efficiency ratings.
Q: How does the warranty work for a 660W solar panel?
A: Most 660W solar panels come with a 25-year linear performance warranty, meaning they are guaranteed to produce a certain percentage of their original rated power after 25 years. A product warranty, covering manufacturing defects, is also standard, typically ranging from 10 to 15 years.
Q: How many 660W panels would I need for my project?
A: The number of panels required depends on your total energy needs (kWh), your location's solar irradiance, system losses, and the desired percentage of energy offset. Our technical team can provide a detailed system design and estimate the number of panels needed.
