Sanyo HIT Double
Note: As of now (spring 2012) the double is out of stock.
One of the issues facing cruising sailboaters is having enough room for all the solar panels needed to run the boat. The Sanyo HIT Double, a bifacial panel, makes the most energy per square inch of any solar panel available. It does this by gathering light energy from the bottom as well as from the top. So, if you are installing the panels on an arch or on davits, sunlight reflected from the water and/or from a white dinghy can be made into electricity. These panels are rated at 195 watts, but that does not include the power that comes from the bottom because of the standard used to test panels. The back face of a HIT Double panel generates electricity from ambient light reflected off surrounding surfaces, and combines with power from the front face of the panel. Depending upon system design and amount of reflected light, this results in up to 30% higher power generation (more kWh) per square foot.
HIT bifacial solar cells are hybrids of single crystalline silicon surrounded by ultra-thin amorphous silicon layers, available solely from SANYO. The crystalline silicon is the most energy-efficient, and the amorphous is more shade tolerant, so this is a combination of the best of both worlds.
As temperatures rise, HIT Double solar panels produce more electricity than conventional solar panels at the same temperature, due to their low temperature coefficient. So they work very well for tropical and subtropical areas!

Thin, Walk-On Solar for your Boat
• Efficient – monocrystalline silicon provides twice the power of thin film panels
• Ultrathin – All models are only 3/16″ (4.5 mm) thick
• Light-weight – ideal for racing, or for mounting on a bimini, dodger or other light structure
• Flat front – there is NOTHING protruding from the surface that can catch sheets, sails or your feet
• Snug-fit back – wires are recessed and protected in grooves, either mounted hidden through tiny holes to interior or without holes on top
• Rugged – sealed with a durable UV-resistant surface, salt water proof to IP67
• Step-on – you can step on the textured surface and add optional anti-skid strips
• Mount on curved surface – the narrow Bluewater modules are slightly flexible and can be installed to follow a curved cabin roof or deck
• Temporary use at anchor – mount on boom with bungee cords, then store under bunk or cushion while underway
• Partial shade resistance – an array of modules is less sensitive to major power loss from boom, mast and sail shadow than a large single panel
• Beautiful – not an eyesore on the boat you are so proud of

How to Select Solar Modules
How do you know which one(s) to get? The first question you should ask yourself is “Where will I mount it on my boat?” Refer to the Solar FAQ page and read #3. Look at your chosen site. How often does that area get shadowed? Choose high output technology for sites that get a lot of full sun; choose shade tolerant technology for sites that are often or always shadowed. Go back to the Solar FAQ page and read #8. Then measure the dimensions of your chosen location, and find a module that will fit within that area.
Please contact us if you need details on solar modules not shown here or need help on deciding what’s right for you.
Note; as of spring 2012 the supply and pricing is changing rapidly. Please call for the latest information.

Choosing a Solar Module
Which module you choose will depend partly on your available space and its size and partly on how much and how often that space is shadowed. If you plan to put a module across your dodger where it will be shadowed by the boom, then choose one of the shade-tolerant modules. You’ll get more power from it in the long run. If you can put one (or more) above your davits (or on your arch) where it isn’t likely to be shadowed, then go with a high output technology. And we’re available to assist you with your choice.
