Where a conventional panel collapses the moment an aircon unit, aerial or thorn-tree branch throws a shadow across it, the ShadowFlux keeps working. It is the panel to fit when your caravan roof is busy and you cannot guarantee a clear, unshaded run of sun all day.\u003c\/p\u003e\u003ch2\u003eWhy This Product\u003c\/h2\u003e\u003cp\u003eAnyone who has watched a solar controller on a caravan roof knows the frustration: the panel is in full sun at 10am, and by 11am the shadow of the aircon shroud or the awning rail has crept across two cells and the charge current has fallen off a cliff. That is not a fault, it is how ordinary panels are wired. A standard 200W panel has two bypass diodes, so shading a handful of cells can knock out a third or all of the module.\u003c\/p\u003e\u003cp\u003eShadowFlux changes the internal circuit. Renogy fits 28 bypass diodes instead of two, so current is routed around individual shaded cells rather than shutting down a whole string. In Renogy's own comparison testing, a 200W ShadowFlux panel still produced roughly 85% of its output with 10% of the panel shaded, where the traditional 200W panel it was tested against dropped to zero. The same design keeps heat out of the shaded cell, which is what causes hot spots and long-term damage on conventional modules.\u003c\/p\u003e\u003cp\u003eFor a South African caravanner that matters in three everyday situations: parking under a shade tree at a Karoo or bushveld camp, roof clutter throwing moving shadows, and dust or bird mess sitting on a couple of cells between washes. You also get the general N-Type advantages - better heat tolerance, which counts in a Kalahari summer, and better low-light performance early and late in the day.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e28 bypass diodes (cell-level shade bypass)\u003c\/strong\u003e – current is diverted around shaded cells instead of collapsing a whole string, so partial shade costs you a slice of output rather than all of it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximately 85% output with 10% of the panel shaded\u003c\/strong\u003e – Renogy's comparison test against a traditional 200W panel, which fell to zero under the same conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eN-Type cells, 25% cell efficiency, 16 busbars\u003c\/strong\u003e – more watts per square metre of roof, and finer current collection that reduces losses around micro-cracks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature coefficient of -0.27%\/degC\u003c\/strong\u003e – noticeably less output lost to heat than typical P-Type panels, which is exactly what an SA summer roof does to a panel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHot-spot resistance\u003c\/strong\u003e – shaded cells are bypassed rather than driven into reverse, so they do not cook themselves the way they do on a conventional module.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP67 junction box and IP67 solar connectors\u003c\/strong\u003e – sealed against dust and driving rain on a gravel road or a Cape winter storm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-iron tempered glass with POE encapsulant and anti-corrosion aluminium frame\u003c\/strong\u003e – built for permanent outdoor mounting, not seasonal use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1262 x 764 mm footprint, 10.81 kg\u003c\/strong\u003e – a compact 200W module that fits roofs where a full-size 200W panel will not.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-drilled mounting holes\u003c\/strong\u003e – works with standard Z-brackets, corner brackets and tilt mounts.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIdeal For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOff-road caravans and campers with a cluttered roof - aircon, hatches, aerials, awning rails - where shadows move across the panel through the day.\u003c\/li\u003e\n\u003cli\u003eCampers who deliberately park under trees at bush and river camps and still expect the batteries to charge.\u003c\/li\u003e\n\u003cli\u003eAnyone replacing an older 100W or 150W panel and wanting more output from the same or less roof area.\u003c\/li\u003e\n\u003cli\u003eRooftop tent and 4x4 canopy builds where roof space is tight and every square metre must earn its keep.\u003c\/li\u003e\n\u003cli\u003eFixed off-grid installations - cottages, hunting camps, borehole pumps - on sites with partial shading from trees or structures.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eLocal Support from 4Matt Campers\u003c\/h2\u003e\u003cp\u003e4Matt Campers is a Renogy dealer in Cape Town, serving the Western Cape and delivering across South Africa. We sell Renogy as a system, not as boxes: if you tell us your battery bank, your daily draw and what is already on your roof, we will tell you honestly whether one ShadowFlux panel is enough, whether you need two in parallel, and which charge controller suits the combination.

This panel's 36.5 V open-circuit output must go through a charge controller sized for it, which then charges your 12V battery. An MPPT controller is the sensible choice here - at 31.3 V Vmp there is a real voltage gap to harvest, and an MPPT will convert that surplus voltage into extra charge current that a PWM controller simply throws away. Check that the controller's maximum PV input voltage comfortably exceeds 36.5 V, and remember that Voc rises in cold weather.\u003c\/p\u003e\u003cp\u003eFor mounting, Renogy Z-brackets are the standard fixed option; corner brackets suit a drill-free bonded installation on a fibreglass or aluminium roof, and tilt mounts help if you want to angle the panel in winter. Use proper double-insulated solar cable sized for the run, seal every roof penetration correctly, and fit a fuse or breaker between the controller and the battery. If you are running two panels, decide series or parallel based on your controller's input window - two of these in series gives 73 V Voc, which many 12V MPPT controllers will accept but some will not.\u003c\/p\u003e\u003cp\u003eWe are happy to quote the panel on its own or as a complete kit with controller, cable, brackets, glands and fusing.\u003c\/p\u003e\u003ch2\u003eComplete Your Setup\u003c\/h2\u003e\u003cp\u003ePair this panel with the right electronics: browse \u003ca href=\"\/collections\/solar-charge-controllers\"\u003eSolar Charge Controllers\u003c\/a\u003e for the MPPT unit that suits it, \u003ca href=\"\/collections\/lithium-batteries\"\u003eLithium Batteries\u003c\/a\u003e to store what it makes, \u003ca href=\"\/collections\/inverters-inverter-chargers\"\u003eInverters \u0026amp; Inverter Chargers\u003c\/a\u003e for 230V appliances, and \u003ca href=\"\/collections\/electrical-accessories\"\u003eElectrical Accessories\u003c\/a\u003e for cable, glands, fuses and connectors.

The 28 bypass diodes route current around shaded cells, and Renogy's comparison test showed roughly 85% output with 10% of the panel shaded versus zero from the traditional panel tested alongside it. Output still falls as shading increases - it is not immune to shade, it just degrades gracefully instead of switching off.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I connect this panel directly to my battery?\u003c\/strong\u003e\u003cbr\u003eNo. Its open-circuit voltage is 36.5 V and it must run through a charge controller, which regulates the voltage and manages the charge profile for your battery chemistry. Connecting a panel straight to a battery will damage the battery.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMPPT or PWM controller?\u003c\/strong\u003e\u003cbr\u003eMPPT. With a 31.3 V Vmp feeding a 12V battery there is a large voltage difference, and an MPPT controller converts that into additional charge current. A PWM controller would waste most of it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill it fit on my caravan roof?\u003c\/strong\u003e\u003cbr\u003eIt measures 1262 x 764 mm and weighs 10.81 kg, which is more compact than most 200W panels. Measure your clear roof area first, allowing for the bracket footprint and enough clearance to avoid resting the panel against hatches or the aircon shroud.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I run two of these together?\u003c\/strong\u003e\u003cbr\u003eYes. In parallel they stay at roughly 36.5 V Voc and double the current; in series they reach about 73 V Voc at the same current. Which one you choose depends on your charge controller's maximum PV input voltage and current ratings - send us your controller model and we will confirm.\u003c\/p\u003e","brand":"Renogy","offers":[{"title":"Default Title","offer_id":48299565056185,"sku":"RSP200DC-ASR-G1-SA","price":5395.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0764\/4587\/6409\/files\/01__73677.1730283812.1280.1280.jpg?v=1784793332","url":"https:\/\/www.4mattcampers.co.za\/products\/renogy-200w-shadowflux-rigid-solar-panel-topcon","provider":"4Matt Campers","version":"1.0","type":"link"}
