PRODUCT DETAILS
The Go Power! GP-ECO-10 is a 10W monocrystalline solar trickle charger that keeps a stored 12V battery full: panel, 23 ft cable with built-in fuse, SAE connections to the battery and rooftop mounting hardware, with no charge controller required. It returns about 3Ah a day — enough to offset the parasitic draws of a parked RV, boat, tractor or trailer (propane detector, stereo memory, control boards) and prevent the sulfation that kills lead-acid batteries in storage. 10-year panel warranty and a North American support team (part of Dometic).
Built to the standard RV manufacturers install
Go Power! has designed mobile power since 1996 and is the solar brand fitted at the factory by Jayco, Forest River, Thor and other leading RV builders. The Eco series is the entry point to that range: the same tempered-glass monocrystalline modules and anodized frames, sized for battery maintenance. Part of Dometic.
Why no controller?
A 10W panel delivers about 0.6A at peak — under 1% of a 100Ah battery's capacity per hour — which a healthy 12V lead-acid or lithium battery of 75Ah or more absorbs without overcharging. For batteries under 50Ah, or if you later add a larger panel, add a Go Power! 10A controller (GP-SB-PWM-10).
Set and forget
Mount the panel on the roof or lay it on the dash, run the 23 ft fused cable to the battery, clip the SAE connection on. Through a winter of storage the battery stays at full charge and starts the season healthy.

FAQ
Do I need a charge controller with a 10W solar panel?
Not for a 12V battery of 75Ah or more. At 0.6A peak the panel cannot overcharge a battery that size, which is why trickle chargers up to about 10W are sold without one. Add a controller for small batteries (under 50Ah) or if you expand the system.
What can a 10W solar trickle charger do?
Keep a stored battery full. It replaces the 2–4Ah a day a parked RV, boat or tractor draws in standby. It will not power lights or appliances while camping — for that, start at 80W.
Does it work with lithium batteries?
Yes. A LiFePO4 battery with a BMS accepts the small current directly. Note that lithium self-discharges very slowly, so the panel mainly offsets parasitic loads.
Can I mount it on the dashboard instead of the roof?
Yes. Many owners lay it on the dash behind the windshield in storage; output drops 20–30% through glass but is still enough to maintain a battery.
Is Go Power! the solar installed in my RV from the factory?
Very likely, if your coach is a Jayco, Forest River, Thor or many other brands. Go Power! has supplied RV manufacturers since 1996; the Eco series uses the same module construction in a maintenance size.
What's the warranty?
The panel carries a 10-year limited power-output warranty, backed by a North American support team (part of Dometic).
