On a PWM controller it would be dragged down to battery voltage and you would lose roughly a third of the output. On MPPT the high voltage is an advantage: the controller converts the surplus into charge current, and the higher voltage means lower current in the roof cable.\u003c\/p\u003e\u003ch3\u003eWhy higher voltage helps on a van\u003c\/h3\u003e\u003cp\u003eAt 6.46A of operating current, a 200W panel at 31V pushes far less current down the cable than a 12V panel of the same wattage would. Less current means less volt drop and thinner, cheaper cable from the roof to the controller — which matters on a long-wheelbase van or a motorhome.\u003c\/p\u003e\u003ch3\u003eBefore you order\u003c\/h3\u003e\u003cp\u003eVoc of 37.44V rises further on a cold, bright morning, so check your controller's input ceiling before putting two in series — that is nearly 75V at standard conditions. The Z-bracket option is worth taking if you have not already sourced mounts.\u003c\/p\u003e","brand":"Renogy","offers":[{"title":"Default Title","offer_id":51358098391207,"sku":"RKIT200IL-ZB2DC1-UK1","price":122.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0770\/1158\/3143\/files\/RKIT200IL-ZB2DC1-UK1_04e98645-79b3-446d-bede-d1d5aba3305e.jpg?v=1789800875","url":"https:\/\/shop.roamwired.com\/products\/renogy-16bb-n-type-200-watt-24v-solar-panel","provider":"Roam Wired Shop","version":"1.0","type":"link"}
