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. Come in and see us or call us about our solar panels!

 

 

 

Monocrystalline vs Polycrystalline Solar Panels:

Busting Myths

One of the most common comments that our specialist team hear from customers relates to the issue of monocrystalline 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 monocrystalline 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 monocrystalline 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.

MC4 Connectors and Pre-Assembled Leads

Second generation MC4 PV connector from Multi-Contact, which has rapidly become the most accepted connector in the world. The MC4 plug connector is designed to accept 4-6mm2 solar cable and is proven MC Multilam technology with high long term stability. 

For a proper seal, MC4s require the usage of a cable with the correct diameter. Normally double-insulated (insulation plus black sheath) and UV resistant (most cables deteriorate if used outdoors without protection from sunlight). Connection is made by use of a special crimping tool, alternatively by soldering. 

All Solar Panels are now generally coming with leads on the back with these types of Multi-Contact Connectors. Some smaller modules still have junction boxes, but any panel 80w and above will usually come with MC Connectors.

MC4 Pre-assembled Leads

MC4 Male to Female extension leads are handy for extending the cables from the back of solar panels for grid or off grid solar installations.

These are available in 1m, 2m, 3m, 4m, 5m, 6m, 8m, 10m, 12m, 14m & 16m lengths. I.e If cut in half the 8M lead would give you 4 metres for the positive side and 64 metres for the negative. Usually these are used for grid/ residential panels for high voltage, low current strings. Keeping in mind that the cable is 4mm2 you'll need to keep voltage drop to a minimum when selecting the appropriate length.
