Retreat-E 100W Solar Expansion Kit","description":"\u003cp class=\"nvn-hero\"\u003eAlready running a Go Power solar setup and still coming up short by mid-afternoon? The Retreat-E 100 Watt Solar Expansion Kit adds another 100 watts of monocrystalline panel to the system you already own, feeding your existing charge controller through included expansion connections. Mounting hardware's in the box. It's the clean way to add daytime charging for boondocking, anchoring out, or dry camping off the grid.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eSo you've already got a Go Power solar setup on the roof, and you're still watching the battery bank sag by mid-afternoon. That's exactly what this kit is for. The Retreat-E 100 Watt Solar Expansion Kit adds another 100 watts of monocrystalline panel to the system you already own, feeding straight into the charge controller that's already wired in. No second controller. No second regulator. You add a panel, you add the power.\u003c\/p\u003e\n\u003cp\u003eHere's the part people miss. This is an expansion kit, not a standalone system. It's built to bolt onto an existing Go Power charging setup and share that same controller through the included expansion connections. If you don't already have a Go Power base kit on the rig, this panel by itself won't regulate the charge, and you'll want to start with a full kit first. But if you're already running one and just need more amps, this is the clean way to get them.\u003c\/p\u003e\n\u003cp\u003eThe panel itself is monocrystalline, which is the type that squeezes the most watts out of every square inch. That matters when you're fighting for real estate on an RV roof or a boat's cabin top. It measures 47-1\/16 inches long by 21-7\/16 inches wide and stands just 1-3\/8 inches tall, so it stays low and out of the wind. Rated output is 100 watts and 5.43 amps in full sun. The mounting hardware comes in the box, so you can lag it down and get it wired the same afternoon.\u003c\/p\u003e\n\u003cp\u003eOn the wiring side, the kit lands its output into your existing Go Power controller through the expansion connections, so that one controller keeps regulating the whole array. If you're running an MPPT controller, you'll hold efficiency better in the heat you get on a summer roof or an open deck. A PWM controller still works fine, you'll just give up a little when temperatures climb. Either way, the panel doesn't care, it just needs sun.\u003c\/p\u003e\n\u003cp\u003eLet's be honest about what 100 watts really does. On a clear summer day with the panel flat and unshaded, you'll see close to the rating. In the real world, with the sun at an angle or a bit of shade from a boom, a mast, or a roof vent, you'll pull more like 70 to 85 watts. That's still a solid chunk of daytime charging, enough to keep a 12-volt house bank topped off while you're anchored out or dry camping, and enough to stretch how long you can go between engine runs or shore power.\u003c\/p\u003e\n\u003cp\u003eMounting is straightforward on most RV roofs. On a boat, take a minute to plan the run. The expansion cable is sized for a normal roof, so on a longer trawler or a stern-to-bow run you may need to extend it with marine-grade 10 AWG wire. Seal every penetration with good butyl tape or marine sealant, and if you're mounting on fiberglass or a radar arch that flexes, a set of rubber isolators under the frame will keep the panel from cracking over a few seasons. None of that's complicated. It's just the difference between a mount that lasts and one that leaks.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Boondockers, weekend anglers, cruisers, and anyone running a Go Power system who's tired of rationing power after lunch. It won't run an air conditioner, and it isn't meant to. What it does is add steady, quiet daytime charging to a bank you already trust, one panel at a time. And because it uses the controller you've already got dialed in, adding it is about as painless as solar gets. Bolt it down, run the leads, snap in the expansion connections, and you're pulling more amps by the next sunny afternoon. That's the whole point of an expansion kit, more power without starting over.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e100 watts of monocrystalline solar, adding up to 5.43 amps of peak charge to your existing Go Power system\u003c\/li\u003e\n  \u003cli\u003eExpansion design feeds into the charge controller you already run, so there's no second regulator to wire in\u003c\/li\u003e\n  \u003cli\u003eMonocrystalline cells pull more watts per square inch, which counts when roof or deck space is tight\u003c\/li\u003e\n  \u003cli\u003ePanel measures 47-1\/16 by 21-7\/16 inches and sits just 1-3\/8 inches tall, low enough to stay out of the wind\u003c\/li\u003e\n  \u003cli\u003eMounting hardware and expansion connections included, ready to bolt down and tie into the array\u003c\/li\u003e\n  \u003cli\u003eFeeds a 12-volt house bank for boondocking, anchoring out, or dry camping off the grid\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Go Power reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat comes in the Go Power Retreat-E expansion kit?\u003c\/summary\u003e\n    \u003cp\u003eYou get the 100 watt monocrystalline solar module, the mounting hardware to bolt it down, and the expansion connections that tie it into your existing Go Power system.

As a rough guide, 100 watts puts back roughly 25 to 35 amp-hours on a good day.
