Solar Panels

Solar panels are devices for capturing the energy in sunlight.

Solar photovoltaic panels contain arrays of solar cells that convert light into electricity.

They are called solar after the sun or "Sol" because the sun is the most powerful source of the light available for use.

The solar cells are sometimes called photovoltaic cells, photovoltaic meaning literally "light-electricity".

With over 25 years of experience in the industry, at The 12 Volt Shop we pride ourselves on our range of solar panels and the knowledge of our staff.

We are the Australian experts in solar equipment for mobile applications such as caravans or motor home's.

Mono crystalline vs Polycrystalline Solar Panels:

Busting Myths

One of the most common comments that our specialist team hear from customers relates to the issue of mono crystalline vs polycrystalline (or ‘multi crystalline’) solar panels. Although mono crystalline panels had the initial advantage of being seen as the superior technology in the Australian market, as time goes on and both technologies improve, it becomes increasingly apparent that the the quality and reliability of the manufacturer is far more important than which of the two technologies is chosen.

Monocrystalline cells are made from a single crystal of ultra pure silicon. They are the original silicon solar cell and they are still the most efficient today. Mono cells are typically a little more expensive since they’re a little more difficult to manufacture. The benefit of mono cells is that they perform slightly better under low light conditions equating to better production on cloudy days versus polycrystalline panels. How much better?. Suffice to say, you may get up to about 0.5% better production per annum using mono cells versus using polycrystalline.

Polycrystalline cells are made up of multiple crystals and are generally less expensive to manufacture than mono cells. The gap in performance has narrowed significantly over the years to the point where they are very close. Since Polycrystalline panels are made up of several crystals, this means that they also absorb less sunlight and produce slightly less than mono cells per metre squared.

Single crystal silicon is more efficient at converting photons to electrons for electricity, the poly-silicon its much less efficient because electrons are captured or generated less efficiently where the crystals of silicon touch. However, even though poly solar panels are not as efficient, they are cheaper to manufacture so they can still be competitive on a $/watt basis. They would just need more area to produce the same amount of electricity as the mono-crystalline panels.

Even though a mono crystalline panel has the potential to last up to 50 years, most warranties only go up to 25 years which polycrystalline panels are able to reach just fine.

Overall, the production process for mono crystalline silicon is mature, and the process for polycrystalline in still maturing. As purity and process tolerances for polycrystalline improves, the performance gaps between the two are narrowing.

Uni-Solar *

*NOT MANUFACTURED ANYMORE - LIMITED STOCK AVAILABLE

*Unfortunately Uni-Solar Panels are no longer manufactured, and there are limited stock available of the modules left.

Uni-Solar have panels suitable for every application. Uni-Solar Technology is available in framed, flexible, portable and the new adhesive PVL range. These new PVL modules can be adhered to many surfaces including fibreglass, aluminium and galvanized or painted metal surfaces.

Why Do UNI-SOLAR Products Outperform Others?

All solar panels are rated in terms of peak power output (watts).

Outdoors, under normally higher operating temperatures, solar panel performance changes, depending on temperature, solar spectrum (light color) and related effects.

UNI-SOLAR products are less affected by temperature than monocrystalline or polycrystalline solar technology products.

The result is up to 20% more delivered energy.**

** Source Solfest, “Module Shoot Out”

Arguably Uni-Solar panels are the best suited to the Australian environment with many benefits putting them ahead of the rest of the pack. The most notable benefits are:

Uni-Solar: Portable *

*NOT MANUFACTURED ANYMORE - LIMITED STOCK AVAILABLE

UNI-SOLAR portable folding solar battery chargers convert sunlight directly into electricity using UNI-SOLAR Triple Junction Technology. The portable PV-modules are extremely rugged, and their unique design makes them easy to carry and deploy.

The UNI-PAC can be dropped, stepped on, packed and re-deployed while continuing to operate. Designed to meet requirements for durability, performance and reliability, the UNI-PAC features a strong, long-lasting front cover made of ETFE.

In addition to normal Uni-Solar properties these panels are:

Product Description:

Individual solar laminates within the UNI-PAC modules contain bypass diodes, making the UNI-PAC solar chargers tolerant of severe shadow or partial covering. The tough nylon fabric covering of the UNI-PAC allows the unit to be folded to a convenient book size, for easy storage and transport. The UNI-PAC 15 and UNI-PAC 30 are for 12V charg- ing only. The UNI-PAC 10 can be used for 12 or 24V charging. They have a 2-pin SAE-connector; and a 2 ft. fused battery cable is packed in their pouch.

PowerFilm Solar

PowerFilm Solar panels are made using thin film solar panel technology and an industrial scale manufacturing process to produce low cost solar panels.



PowerFilm Rollable Solar Chargers

LIMITED STOCK AVAILABLE

Integrated Technology Package

Because PowerFilm integrated solar panels (thin film on plastic) are developed and manufactured with a proprietary roll process, by Iowa Thin Film Technologies, they are truly rollable unlike other thin film technologies that are only somewhat flexible. PowerFilm solar panels are all monolithically integrated which eliminates the need for damage-prone manual connections of individual solar cells. PowerFilm is made of silicon, a natural resource in abundant supply. PowerFilm is Cadmium Free, unlike some other solar technologies, and performs well in diverse environments, including hot sun, and does not suffer from wasted over-voltage.

Ultra Rollable

PowerFilm products are ultra rollable because they are manufactured on a roll up to 2400 feet long, using the proprietary roll-to-roll manufacturing technology platform of Iowa Thin Film Technologies. Iowa Thin Film Technologies is the first and only company in the world selling solar products manufactured on a true roll-to-roll process using a plastic substrate.

Durable

PowerFilm products are monolithically integrated which eliminates the need for damage-prone manual connections of individual solar cells. PowerFilm products are constructed using a durable polymer (plastic) substrate.

Easily Integrated

Several features enable easy integration: Paper thin low profile; Ultra flexibility allows conformity to shapes; Complete product design eliminates need for unsightly bolt-on frames.

Fabric Integrated

Integrated with a fabric backing for enhanced product functionality.

Lightweight

Constructed using a proprietary combination of thin and lightweight materials.

Environmentally Friendly Profile

Cadmium Free! (Other solar technologies such as CIS, CIGS, and CdTe contain cadmium which is considered an extremely toxic metal by the Department of Labour.) If comparing products, check to be sure they are Cadmium Free. Primary element used in PowerFilm is silicon, a natural resource in abundant supply.
