Frequently Asked Questions
What does “bifacial” mean for a solar panel, and how does it increase efficiency?
“Bifacial” means the panel can generate electricity from both sides, not just the front. Light reflected onto the back surface contributes to production. Some claim this can boost the panel’s power output.
I see different “BB” numbers (like 9BB, 10BB, 16BB) listed. What does this refer to, and should I care?
BB stands for busbars, those thin lines you see on the solar cells. More busbars can lead to less resistance and better current flow, potentially giving you a bit more power and reliability.
What does the wattage mean for solar panels?
Wattage represents the maximum power output of a solar panel under ideal conditions. Higher wattage panels can generate more electricity if you have the space to install them.
Are these solar panels easy to install myself, or do I need a professional?
Some panels are easier. Look for “plug & play” connectors or pre-drilled holes that are easy to mount. Depending on your setup and local regulations, you might prefer help from a pro.
What kind of maintenance do these solar panels require?
The panels require minimal maintenance. It is a good idea to occasionally clean them off. Check on your installation setup and connections occasionally.
