Why Solar Power Is Ideal on the Water
Being on the water often means being off the grid. Whether you're moored overnight or on a multi-day adventure, electricity can be hard to come by. That’s where solar on water becomes a game-changer.
Here’s why solar is a perfect fit:
- ☀️ Abundant Sunlight
Open water usually means great sun exposure.
- ⚓ Energy Independence
No need to rely on marina hook-ups or land-based charging.
- 🧘 Silent & Clean Power
Say goodbye to noisy, fuel-burning generators.
- 🌍 Eco-Friendly
A sustainable way to power your life without polluting your environment.
What Are Solar Water Panels?
Solar water panels typically refer to photovoltaic (PV) panels designed for aquatic or water-adjacent settings. They come in various types and can be used in different ways, depending on your needs.
Types of Solar Panels for Water Use:
- Rigid Panels for Boats – Fixed on rooftops or deck areas for continuous, reliable energy (see our Boating section for more).
- Flexible Solar Panels – These can curve over boat hulls or mount on irregular surfaces.
- Floating Solar Panels – Gaining popularity on ponds, lakes, and even reservoirs. Mostly for stationary setups but an exciting emerging technology.
- Standalone Solar Water Features – Think solar-powered fountains, waterfalls, and aerators—especially popular in the UK garden and water feature scene.
🛒 Sunstore offers a great range of marine and flexible solar kits that are suitable for boats and water-based installations.
Common Uses of Solar Power on Water
From boating holidays to maintaining your garden pond, solar water panels are more versatile than ever. Here's how you can use them:
🔋 Boating (Big or Small)
Power lighting, fridges, navigation systems, pumps, and more. It’s one of the most common and practical uses of solar energy on water. See our full guide in the Boating subcategory.
🌿 Solar Water Features UK
From decorative fountains to functional pond aerators, these are great for homeowners who want beauty and sustainability in their garden. They're easy to install and require no wiring.
🎣 Solar Water Panels for Fishing Trips
Solar panels can keep your gear (like fish finders, lights, or cameras) running on longer trips out on the water.
🚣 Canoes & Kayaks
While lightweight solar setups won’t power the vessel itself, they’re excellent for charging phones or running a GPS unit on the go.
🏕️ Dockside Charging Stations
Floating docks and piers can have their own mini solar setups to provide lighting or power for nearby boats and equipment.
How Much Power Do You Need?
The beauty of solar on water is that it can scale to your needs. From small-scale fountain kits to full off-grid boat systems, there’s a solar solution for every kind of adventurer.
| Use Case | Suggested Solar Panel Size | Battery Bank (Optional) |
| Pond Water Feature | 1–5W | Usually not needed |
| Fishing Kayak Setup | 10–20W | 10,000mAh power bank |
| Narrowboat Power | 100–300W | 100Ah+ AGM or lithium |
| Liveaboard Cruiser | 400–1000W | Full battery bank + inverter |

Choosing Solar Water Panels: What to Look For
⚓ Marine-Grade Durability
Saltwater and constant movement require waterproof, corrosion-resistant gear.
🔋 High-Efficiency Output
Especially important for smaller boats or space-limited surfaces.
🛠️ Easy Installation
Look for kits with mounting options or that can flex to fit curves and non-traditional shapes.
🌐 Compatibility with Controllers & Batteries
Ensure your solar panel works seamlessly with charge controllers, batteries, or direct DC-powered devices.
How to Set Up Solar on Water
Installing solar on water can vary greatly depending on your project, but here’s a basic outline for a boat-based setup:
- Mount the Panels – Fixed to a roof, canopy, or rail system.
- Wire to a Controller – This regulates the power coming from the sun.
- Connect to a Battery – Store power for night-time or cloudy days.
- Run Your Gear – Lights, electronics, even refrigeration.
Floating or garden setups are even simpler—most solar water features are plug-and-play and need just a few minutes to install.
