1. 0:00All right. So, I want to show you an
2. 0:02example of
3. 0:04300 W panel. So, this is a 300 W
4. 0:06polycrystalline panel.
5. 0:08So, behind it, you can see
6. 0:12the description
7. 0:15behind it.
8. 0:17So, here,
9. 0:19see?
10. 0:20It's showing you
11. 0:25the open voltage of 38.4.
12. 0:28So, this is what you look with uh
13. 0:30purchasing your panel. You first of all
14. 0:32use a multimeter, that's in the toolbox,
15. 0:35or you buy it.
16. 0:36With a multimeter, you're going to use
17. 0:38the positive points to the positive of
18. 0:40this panel, negative to the negative. It
19. 0:42will not show you if the voltage is
20. 0:45accurate, if the panel is in good
21. 0:46condition. So, now that you have this
22. 0:49open voltage of 38.4, when you read it
23. 0:52with your multimeter, you might see 33
24. 0:54or 34. That means the panel is in good
25. 0:56condition.
26. 0:58All right. So, this is an example of a
27. 1:00650 W solar panel, monocrystalline.
28. 1:04All right. So, this is a bifacial solar
29. 1:07panel. It's of two form. We have
30. 1:09uh a one-face monocrystalline and
31. 1:11bifacial is two,
32. 1:13front and back
33. 1:15monocrystalline panel. So, come and see
34. 1:17the bifacial part of it. So, this is
35. 1:19front view.
36. 1:21And this is the back view.
37. 1:24Yeah. So, you see?
38. 1:26We have collected 30% of heat from the
39. 1:29rooftop, while I get 70% from the
40. 1:32sunlight.
41. 1:33So, this is also the
42. 1:35the rating of the panel as well.
43. 1:38So, this is the company name. You know
44. 1:40the company is Longi.
45. 1:42All right. It's the most preferred when
46. 1:43it comes to panel. And this is 650
47. 1:48W.
