Marine Solar Kit ICP SolarPro Kit Solar Boost Charge Controller Flexible Solar RollUni-Solar Triple Junction Module Solar Pathfinder

Solar panels (= solar modules) are essentially an assembly of many solar cells encapsulated behind a glass plate mounted in an aluminum frame for better protection and handling. If you expose them to (preferably direct) sunlight they will generate a voltage, typically 12-15V, with a current depending on the suns intensity and the angle facing the sun.

Only recently became available solar panels which are flexible. These facilitate compact transport (when rolled into a tube), lighter weight (no Al frame), no cells that can break (e.g. when dropped) and often easier installation, especially on non-plane surfaces, such as boats or round buildings.

In order to properly charge (not overcharge or drain) a battery you will need a charge controller that ensures optimal charging at all weather / light conditions. Consult a book on photovoltaic or solar electric systems from the books section or a solar kit from the educational & toys section if you are not confident with what you need!

Uni-Solar Marine Flex modules are now available! These flexible triple junction modules (solar panels) can be rolled down to an 8-inch diameter without damage.

Features blocking diodes within the potted junction block to prevent battery discharge and nickel-plated brass grommets at corners. Includes eight feet of cable with built-in fuse holder and a 2-pin SAE connector.

Uni-Solar Marine Flex modules come in three different sizes to deliver 5, 11 or 32W. For more power, just connect several of these amazing modules in parallel and you can add up the current.

This is the type of module chosen for the Horseback America Expedition. USA.

A flexible lightweight solution. You can use these beautiful panels to power your sailing boat, camping equipment, (mobile) home, and also for some portable cooling boxes.
  • Rated Watts: 5.0 Watts @ 25C; L x W x D: 21.8" x 9.7" x 0.3"; <22$/W*

  • Rated Watts: 10.3 Watts @ 25C; L x W x D: 21.8" x 16.7" x 0.3"; <18$/W*

  • Rated Watts: 32.0 Watts @ 25C; L x W x D: 56.3" x 16.7" x 0.3"; <12$/W

The modules provide decent flexiblity - you can roll them into an 8 inch tube, but not 3 inch as others. Good value for money when some flexiblity is requiered. Download data file (pdf) for USF-5, USF-11 & USF 32 here.

Like all previous Uni-Solar products these unbreakable modules are deposited on a stainless steel backing with DuPont’s Tefzel glazing and, due to unique construction, have the ability to continue useful output during partial shading. Frames are anodized aluminum. Wire pigtails are supplied on 21-, 11-, and 5-watt sizes.

The new triple-junction technology brings the price down to a level equal to or better than single crystal technology. Like all amorphous modules, power output will fade approximately 15% over the first month or two.

Rated power is post fade, and is warranted for 20 years. UL and CUL listed. USA.

 
If you can afford the larger surface area, the Uni-Solar triple-junction modules are one of the best PV bargains available

A great choice for larger multi-module power systems, this large polycrystalline Sharp module features 72 cells with 24-volt nominal output, tempered glass, built-in bypass diodes, and the most robust anodized aluminum frame we’ve ever seen.

Output is via a pair of 51” outdoor-rated cables with simple, quick, watertight MC plugs. Long series strings of modules, as commonly used for higher voltage utility intertie systems, are very quickly assembled with the MC plugs.

The 185 watt module is the same size, voltage, output cables, price per watt, and warranty, but is assembled with single-crystal cells rather than polycrystalline cells. It packs a little more punch per square foot.
25-year warranty - Japan.

 

This panel uses single crystal silicon. For that reason it delivers more power per area than polycrystalline or amorphous panels.

PV modules put out higher voltage than your batteries can accept; that’s lost power. Solar Boost controllers run modules at their maximum power point, and use linear current booster technology to down-convert excess voltage into amperage your batteries can accept. With low-voltage hungry batteries and high-voltage cold modules (winter-time, in other words), the amperage boost will realistically reach 30%. The LCD optional display shows amps in and amps out to easily gauge actual performance.

A battery temperature option is available for batteries exposed to temperatures below 40°F or over 80°F.

All Solar Boost products are made in the USA, and have a three-year mfr’s warranty and now feature ETL listing to UL 1741 specs.

 

A powerful charge controller that can boost the efficiency of your panels by 30%!

Consider the gain in power and it may well be worth the higher price -especially if your currents are anywhere near controllers maximum for the used voltage.

An ingenious and elegant solution for siting your solar array. Windering if that tree of building will shade your array during certain times of the year? In less that two minutes. The Pathfinder will show exactly what times of day and months of the year shade will fall on any site.

It doesn't even need to be a sunny day! One quick siting gives accurate, easily recorded solar site information for the entire year. It only takes a fist-sized chunk of shade to effectively turn off a PV module. The Pathfinder can quickly pay for itself in saved siting mistakes. Every professional needs to own one of these.

For homeowners, there is a $25/week rental program available. USA.

 

Certainly worth the money if your panels are anywhere near objects that may at some time in the year/day cast a shade on your panels.

Partial shadowing can affect the performance of the entire system not just a few cells!

Follows the Sun for Increased Power!

Your own automated solar power station! Capable of over a 160° rotation east to west, the Sun Tracker will increase the power output of photovoltaic arrays by over 200% (solar panels not included), by keeping the face of the panels parallel to the sun throughout the day. Made from light weight aluminum and can be mounted in a fixed location. Weather resistant.

This sun tracking system can be used for small panels to multipy(!) power output by automatically following the suns path in the sky (one axis).

You could use this small version to experiment if you consider a tracking system also for a large system.

Alternatively use several small trackers.

These are the best sealed batteries available anywhere. These true deep cycle gel batteries come highly recommended by the National Renewable Energy Labs.

They are completely maintenance-free, with no spills or fumes. Because the electrolyte is gelled, no stratification occurs, and no equalization charging is required. Self-discharge is under 2% per month. May be airline transported as approved by DOT (Department of Transportation), ICAO (International Commercial Airline Organization), and IATA (International Airline Transport Association).

Life expectancy depends on battery size and use in service, but no sealed battery will perform better or longer than these. Amp-hour rating at standard 20 hour rate. USA.

 

Ideal for most 12V solar systems. Make sure your batteries can't freeze. To get e.g. 24V connect two batteries in parallel (plus with minus).

A 12V charge storage system is typically most practical - however, if you need to run long cables (>10m or so) consider higher voltages to reduce losses or use thicker cables.

General Battery, the largest battery manufacturer, these consist of six propylene cells in what the industry calls a steel tray. Features include heat-sealed cell covers, lead-plated copper intercell connectors, and free freight! Yep, free freight in the continental U.S. to a business with a forklift, or to a trucking terminal.

With proper maintenance these cells will last over 20 years. HUP stands for High Utilization Positive. These use a patented process that reduces positive plate flaking and shedding, the primary cause of eventual battery failure. No battery offers better performance, a longer life expectancy, or a better manufacturer's warranty. Cycle life expectancy is 2100 cycles to 80% depth of discharge, or 6000 cycles to 20% depth of discharge. Interconnect cables are only needed between 12-volt trays; no cell interconnects required. 10-year mfr.'s warranty. USA.

 

Great large batteries for a larger system

1270Ah; 12V; heavy.
