iTechworld Solar Cell Testing Lab

Solar Cell Testing Lab

"We test, test and test again to deliver the industry's most reliable panels"

High temperatures. Dust storms. Coastal erosion. Biting frost. Heavy storms. Blowing sand. Dense snow loads. We look at the testing that the new iTechworld Solar Cells go through before they hit Australian shores. This ensures optimal performance and durability—and maximizes return on your solar investment.

In fact, the testing goes far beyond the most stringent of U.S and international standards, including the International Electrotechnical Commission (IEC) and the International Organization for Standardization (ISO), producing high quality solar cells.

"Every panel must satisfy strict performance and safety criteria—with NO exceptions"

Solar panel hail impact quality test

Hail Impact Test. Replicates a natural hail storm by dropping a 1.1-pound, one-inch steel ball onto the solar cells from a height of 13 feet. This is repeated this up to 20 times in the same place on at least 11 different points of impacts.

 

 

Solar panel breakage quality test

Panel Breakage Test. Subjects the cells to brutal impacts by heavy or hard objects to ensure stability and break-resistance. Occasionally hard objects fall onto solar panels and they will conduct these test to ensure that roof-mounted solar system will withstand these impacts. For good measure, they also drop a 1KG, lead-filled sack from a height of 1 metre onto the middle of vertically positioned solar panels up to three times.

 

 

Solar panel inclined plane quality test

Inclined Plane Test. Tests the effects of snow load on the lower edge of the cells, which simulates real-world conditions since sliding snow and ice apply pressure to the lower part of the frame. Other companies typically test evenly distributed snow load on a horizontal panel, even though installations almost always parallel the slope of a roof. Although this is not really an issue in Australia it is good to know that these sort of tests are performed and quality is assured.

 

Solar panel salt spray quality test

Salt Spray Test. Makes sure the cells are ideally suited for coastal areas and salty air by exposing the solar panel to a salt mist mixture and then storing it under humid conditions to simulate coastal conditions. They voluntarily submit their cells for this optional test to guarantee maximum performance and further demonstrate a commitment to quality.

 

 

Solar panel hemispheric lighting quality test

Hemispheric Lighting Test. Simulates authentic light and temperature conditions to make sure the cells deliver optimal performance in the real world—which includes changing weather patterns.

 

 

Solar panel mechanical load quality test

Mechanical Load Test. Ensures the cells withstand extreme weather conditions, including excessive wind pressure, wind suction and snow load. Alternating pressure and suction is applied up to 1.2 million times using both static and dynamic forces.

 

 

Solar panel UV light aging quality test

UV Light Aging Test. Guarantees excellent results from our solar cells even in some of the brightest spots on the planet. We simulate intense UV radiation, including 1300 kWh/m2 in normal conditions and up to 3000 kWh/m2 in desert conditions.

 

 

Solar panel climate chamber quality test

Climate Chamber Test. Puts our solar cells through extreme temperature fluctuations in order to emulate years of weather changes. In the climate chamber, the modules withstand temperatures as low as -40 degrees Celsius to as high as 85 degrees Celsius. 

 

 

Solar panel peel quality test

Field Installation and Peel Tests. Tests performance by exposing our solar cells to real wind and weather conditions in varying climate zones—not just contrived laboratory conditions. In field tests, data consistently shows our cells perform well above 100 percent of predicted models. At the same time, peel tests confirm the superior reliability of our sheet-to-glass and inter-sheet connections, which is a key contributor to the long lifespan of the cells.

 

Solar panel hot spot quality test

Electrical and Hotspot Tests. Assures optimal insulation and electrical safety in both wet and dry conditions in a broad range of temperatures. Electroluminescence measurements identify otherwise undetectable micro-cracks or contact breaks while thermography cameras search for “hot spots,” which can occur when cells lie in a shadow and heat up as a result of residual electricity, ultimately damaging the panel over time.

Benefits of Using A Portable Jump Starter

Who Needs A Portable Jump Starter?

An iTechworld Portable Jump Starter is the obvious choice for people travelling and for people who enjoy outdoor activities.

Every motorist can benefit from having an iTechworld Portable Jump Starter.  In colder weather for example, keeping a portable starter in the garage on it’s charger is a great way to help a sluggish battery on a cold morning.

After using your iTechworld Portable Jump Starter you can then just throw it in the boot or glove box in case you need it later.

Itechworld got some really interesting feedback from one of our customers:-

"The reason I love these portable jumpers is that I have two daughters.  I don’t want them stranded somewhere asking strangers for a jump. The peace of mind these portable starters give me as a father is well worth the price of two portable jumper packs" - Chester McPherson TAS

This really hits home especially when you consider that about 30% of car problems are caused by battery issues.

We have put together the 5 key benefits of having a Portable Jump Starter

#1. You don’t need to ask for help when you have a jump starter.

The most obvious advantage of a jump starter is the fact that it eliminates the need to find someone to loan their car to be used as a host vehicle, which is required when using booster cables. This advantage isn’t just about the hassle of having to find someone willing to help you. It is also a safety consideration. If you have your jump starter in your glove box, you can pull it out, connect it and get your vehicle started immediately, which is great when stranded at night or in an unfamiliar area.

#2. There’s no accessibility concerns.

Sometimes you can be parked or stranded somewhere that is difficulty to get access to. This becomes even more of an issues if you are disabled. We received some feedback from an iTechworld customer on such an issue.

"My elderly neighbour called me one day. Her husband utilizes a wheel chair and had recently been ill. As a result, they had not used their wheel chair accessible van for a few weeks. Their front porch allows them to pull the van next to the porch and manually open the sliding door to lower the van’s wheelchair ramp onto the porch.

That day, after locking the wheel chair into the locking mechanism inside the van, it was discovered the van’s battery was dead.  The wheel chair mechanism locks when the chair enters it and can only be unlocked electronically. Consequently, the husband was locked into the chair and could not be removed through the passenger door because the van was parked next to the porch – the door could not be opened.

I had jumper cables in my car, but they were not long enough to reach the front of the van due to how it was positioned in the driveway. So, we had no way to power the van to release the wheel chair lock. The situation was remedied when I used my iTechworld Portable Jump Starter.  In a matter of seconds, the van was started and the locking mechanism was released" - Steven Gilchrist NSW

The peace of mind that an iTechworld Portable Jump Starter creates is worth its weight in gold.

#3. Twice the connections means twice the chance for issues.

With booster cables, you have to make two sets of connections, which is twice the chance for issues. Reversed connections are very dangerous to the operator and the vehicles involved. They can create sparks, which could result in an explosion if battery gases are present. They also can cause damage to expensive electronic components on one or both of the vehicles involved, depending on when in the connection sequence the reverse connection takes place. With a jump starter, there is just one set of connections to make, simplifying what can be a confusing process.

#4. Concerns of damage to the host vehicle.

Even when care is taken to ensure a proper connection sequence and starting procedure, there remains the concern of whether the host vehicle is up to the task of providing the additional power needed by the disabled vehicle. If any components of the host vehicle’s electrical system are marginal or suspect, the additional requirements of the jump starting process may push those components over the edge. We remember how we once brought a friend’s car’s electrical system to its knees while borrowing it to use for a jump. We were young, the car was old and it was on the scrap heap within days. This is an extreme example, but there are always risks to the host vehicle when jump starting.

#5. Today’s Vehicles Make Booster Cables Inherently Risky

There are several reasons why using booster cables on today’s sophisticated vehicles brings inherent risks not present when using a jump starter. The first is that noise from the host vehicle can be transferred to the disabled vehicle. This noise can include voltage spikes and other anomalies that could damage sensitive electrical and electronic components on the disabled vehicle. As a jump starter is essentially an extension of the vehicle battery, short of a reverse connection, this concern does not exist.

In Conclusion

So, as you can see there are plenty of reasons to choose an iTechworld Portable Jump Starter over the conventional booster cables.  It’s just a better way of dealing with a dead battery.

If you have been on the fence, wondering if a portable jumper is really worth it, I hope this post will give you an understanding of the key benefits of owning a portable jumper.

Just remember a portable jumper will give you peace of mind, but you do have to maintain it so that when you do need it, it’s ready to go.

Portable jumpers are a life saver but you do have to remember to charge it once in a while.

How does a Generator Inverter work

iTechworld Generator Inverter how it works

The iTechworld Generator Inverter combines the efficiency of DC power generation with a controlled DC to AC inverter to provide clean electrical power similar to the power produced by electric utilities or larger standby home generators. Its efficiency saves fuel, lowers emissions, and reduces noise levels, all of which make it suitable for use in places like campsites and caravan parks. It is also used to power sensitive electronic equipment such as air conditioners, laptops, induction cooktops and other household appliances.

 

AC Power

The electrical power we are all familiar with in our homes is alternating current, or AC, which means the current flow alternates direction rapidly. The standard is fifty times per second in Australia and most of Europe however in the USA it’s 60 times per second. As the current changes directions, the voltage rises and falls to provide an average voltage 240 volts.

The power the electric utility companies supply to homes and businesses is usually very clean and if viewed on an oscilloscope―a device for viewing electrical signals―it appears as a very smooth and consistent sine wave also knows as Pure Sine Wave.

DC Power

Direct current, or DC, is the type of current supplied by a battery. It is very steady, doesn’t fluctuate much under a constant load, and is very efficient. It does not change direction and there is no rising or falling of the voltage level. Viewed on an oscilloscope, it appears as a straight line.

DC current cannot be used on appliances or motors that require AC current, but a device called an inverter changes DC current into AC current. A cheap electronic inverter can approximate an AC signal but doesn’t do it very well and even the power supplied by some other generators isn't really as clean as it should be. All iTechworld Generator Inverters are controlled by a microprocessor, this does a much better job and the converted signal appears as a near-perfect sine wave.

Generator Inverter

An iTechworld Generator Inverter creates AC power through a two-step process. In the first step it generates DC power and then the second step it converts it to AC using a microprocessor controlled inverter.

This method of power production has several advantages.

The generation of DC begins almost as soon as the engine begins turning the generator. As the engine increases in speed, the DC voltage rises. As the load increases, the voltage will fall. The microprocessor controlling the inverter compensates by sensing the AC output voltage of the generator and adjusts the speed of the engine to keep the voltage at a consistent level. This saves fuel since the engine only turns as fast as necessary instead of at a constant high speed.

As demand increases, the microprocessor speeds up the engine and power production increases, but the AC signal does not change. The result is a very clean, efficient and consistent AC Pure Sine Wave signal no matter how much power is drawn, up to the generator's capacity.

Since the engine runs at the lowest possible speed necessary to meet the power demand, an iTechworld Generator Inverter is much quieter during periods of low demand than a conventional generator and uses less fuel to produce clean power.

5 Tips to Get The Most Out of Your Solar Panels

1. Keep 'em Clean solar panels—they work so well that you hardly notice that they're there. And there is the problem. While the system is quiet and runs without a sound its easy to forget that the panels can get dirty, causing the power output to drop. The cleaner the glass is on the panel, the more unobstructed surface the sun has to "work with." How often should you clean your solar panels? That depends on where you are—if there is a lot of dust when you are travelling then your Solar Panels will gather lots of particulates and you will probably need to clean more often. A damp cloth will do the trick.

 

 

2. How to clean your solar panels? First, never use an abrasive soap or cleaning sponge - the goal is to get the glass clean and clear as possible so you don't want to scratch it. A quick wipe down with some water and a soft sponge will get the glass clean. This will give your Solar Panel the chance to produce its maximum output and help keep your batteries charged.

3. Keep them out of the shade. All iTechworld Solar Panels are monocrystalline, meaning they will still produce some sort of power in the shade, however if you want to get the full power from your Solar Panel then it is important to keep them in full sunlight. Different parts of Australia get longer sunlight hours. Check the map below to see how many hours of sunlight you will receive.

4. Monitor the panels. Monitoring your solar panel performance is key in understanding the power you are producing. There are two ways you can monitor your solar panel performance. Firstly you can buy an inline Amp Meter, this device goes inline between your solar panel and your battery. It will accurately tell you how many Amps your Solar Panel  is producing.

The other way to monitor your solar panel performance is to upgrade your regulator to an Intelligent Regulator. Using the iTechworld Intelligent Regulator gives you access to a full Battery management system with a digital screen which gives you a read out on Volts being produced, Volts being used, temperature and how many Volts are left in the battery.

5. Keep a record of your panels' performance day-to-day. If you want to take it one step further, write down what your system has produced for the day (at roughly the same time each day). Make a note or asterisk for days that are particularly overcast because those will throw off your results and don't necessarily mean that there is a problem with your system. Keeping daily accounting will help you determine if your system is still coping with your load. If your current system is not coping with your load, it could be time to update.
