The complexity of the half-cut module manufacturing process is higher, and the structure of the module is smaller in size, making it easier for the diode to open and change the direction of the current flow, which affects power generation but helps to minimize the risk of fire caused by the hot spot of the module.<\/p>","protected":false},"excerpt":{"rendered":"<p>\u534a\u5207\uff08Half-cut\uff09\u6a21\u7d44\u56e0\u9ad8\u74e6\u6578\u8207\u4f4e\u6bcf\u74e6\u6210\u672c\uff0c\u76ee\u524d\u5df2\u6210\u70ba\u5e02\u5834\u4e3b\u6d41\uff0c\u71b1\u5f71\u50cf\u5de1\u6aa2\u7684\u5224\u8b80\u65b9\u5f0f\u4e5f\u96a8\u4e4b\u6539\u8b8a\uff0c\u672c\u6587\u6574\u7406 [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":5709,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_post_was_ever_published":false},"categories":[5,25],"tags":[31],"class_list":["post-5674","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news","category-technology","tag-smart-om"],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/iruav.com.tw\/wp-content\/uploads\/2026\/01\/52d210905690d898f22b32111b056b15.png?fit=600%2C315&ssl=1","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/iruav.com.tw\/en_us\/wp-json\/wp\/v2\/posts\/5674","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/iruav.com.tw\/en_us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/iruav.com.tw\/en_us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/iruav.com.tw\/en_us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/iruav.com.tw\/en_us\/wp-json\/wp\/v2\/comments?post=5674"}],"version-history":[{"count":16,"href":"https:\/\/iruav.com.tw\/en_us\/wp-json\/wp\/v2\/posts\/5674\/revisions"}],"predecessor-version":[{"id":6433,"href":"https:\/\/iruav.com.tw\/en_us\/wp-json\/wp\/v2\/posts\/5674\/revisions\/6433"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/iruav.com.tw\/en_us\/wp-json\/wp\/v2\/media\/5709"}],"wp:attachment":[{"href":"https:\/\/iruav.com.tw\/en_us\/wp-json\/wp\/v2\/media?parent=5674"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/iruav.com.tw\/en_us\/wp-json\/wp\/v2\/categories?post=5674"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/iruav.com.tw\/en_us\/wp-json\/wp\/v2\/tags?post=5674"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
