w/ my old polycrystalline panels i could get at most 75% of the rating on the sticker. monocrystalline should be slightly higher. then there are bifacial that are even higher still if you could somehow reflect light into the back of the panel
13kw ang nakainstall na panels sa akin. bifacial sya. I am able to harvest max of 12kw during the first few months after install. Now 11kw nalang peak. Baka need to clean the panels na.
