Two of these will not fit across most panel van roofs, and at 16.7kg each the pair is over 33kg before mounting hardware. On a coachbuilt motorhome, a horsebox roof or a ground-mounted array they make complete sense; on a Transit Custom they do not.\u003c\/p\u003e\u003ch3\u003ePositive power tolerance\u003c\/h3\u003e\u003cp\u003eRenogy quote 320W with a 0 to +15W tolerance, meaning a panel will never test below its rating and may exceed it. That is a quality signal — cheaper modules are commonly specified with a negative tolerance, so a \"320W\" panel might genuinely deliver 305W.\u003c\/p\u003e\u003ch3\u003eBefore you order\u003c\/h3\u003e\u003cp\u003eAt 10.57A operating current per panel, two in parallel is over 21A — size the controller and the roof cable for it, and remember the 25A maximum series fuse rating. Two in series reaches 70V open-circuit, so check your controller's input window.\u003c\/p\u003e","brand":"Renogy","offers":[{"title":"Default Title","offer_id":51358098456743,"sku":"RSP320DT-BKx2-UK","price":319.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0770\/1158\/3143\/files\/RSP320DT-BKx2-G2.jpg?v=1789800877","url":"https:\/\/shop.roamwired.com\/products\/renogy-320w-n-type-bifacial-solar-panel-2-pack","provider":"Roam Wired Shop","version":"1.0","type":"link"}
