Five fast facts to bring you across all things N-type.
FACT #1: N-type solar cells were developed before P-type
The first solar cell was developed in 1954 – and it was in fact an N-type cell. So why did P-types become so popular?
When solar PV technology was starting out, most of it was being used by space agencies. In space, P-type cells proved to be more resistant to radiation damage than N-types. Hence, more focus and resources were put on P-type cell development, leading to their dominance in today's market.
FACT #2: N-type cells are more efficient than P-type
One of the main differences in the engineering of N-type panels vs P-type panels is their 'doping’. Doping refers to the addition of chemicals to the crystalline silicon to promote power production.
An N-type solar cell is doped with phosphorus, which has one more electron than silicon, making the cell negatively charged (hence the 'N' in N-type).
A P-type cell is doped with boron, which has one less electron than silicon, making the cell positively charged (the 'P' in P-type).
When boron is exposed to light and oxygen, it causes Light Induced Degradation (LID). This happens as soon as solar panels are installed and decreases anywhere between 1% and 3% depending on the brand of the panel.
N-type panels don't use boron and therefore aren't affected by LID. It means better efficiency and improves the useful life of the panel.
FACT #3: N-type cells are more expensive than P-type – however this is expected to change
The downside to N-type panels in today's market is cost. They are more expensive to make and therefore more expensive to buy. With more focus and resources on P-type development, they quickly became more cost effective to produce for manufacturers and cheaper to purchase for end users. Investment into N-types was left behind.
FACT #4: N-type are projected to take over P-type in market share by 2024/25
Industry estimates suggest that N-type panels will be the solar industry's dominant technology by 2024/25 as engineering and manufacturing processes evolve and costs come down.

Solar panels are widely used to generate electricity, but their performance can be affected by contamination such as dirt, bird droppings, and pollen.
Here are 3 tips to clean solar panels:
1. Prioritize safety by shutting down the system before cleaning and using safety ropes for roof-mounted panels.
2. Use gentle cleaning methods to avoid scratching the surface. Clean water, detergent, and a soft brush are ideal tools for the job.
3. Opt for early morning or evening cleaning when the panels are cooler. Cleaning while the sun is shining can lead to quick water evaporation and residue buildup.

The battery C rating can be defined as the measure at which a battery is discharged relative to the maximum capacity of the batteries.
A battery’s charge and discharge rates are controlled by battery C rating. In other terms, it is the governing measure of at what current the intended batteries is charged or discharged and how quickly that occurs.
The capacity of a battery is generally rated and labeled at 3C rate(3C current), this means a fully charged battery with a capacity of 100Ah should be able to provide 3*100Amps current for one third hours, That same 100Ah battery being discharged at a C-rate of 1C will provide 100Amps for one hours, and if discharged at 0.5C rate it provide 50Amps for 2 hours.
The C rate is very important to know as with the majority of batteries the available stored energy depends on the speed of the charge and discharge currents.
Why The C Rating Are Different Between Different Battery?
1C means 1 hour discharge time.
2C means 1/2 hour discharge time.
0.5C means 2 hour discharge time.
In many applications, the battery rate is very important. For example, we want the car to be fully charged within half an hour, instead of waiting for 2 hours, or even 8 hours. What is cause influence to the battery C rating?
There are two limitations to how fast a battery can be charged-thermal heating and mass transfer limitations.
Thermal heating occurs because the internal resistance of the battery generates excessive heat, which must be dissipated to the environment.
When charging occurs at very high currents, the heat generated within the battery cannot be removed fast enough, and the temperature quickly rises.
Mass transfer of Li+ ions during fast charge results in diffusion limiting current even if the electrodes are made of nanoparticles with high surface area. While the high surface area allows sufficient rate of lithiation or de-lithiantion, the Li+ diffusion through the cross-sectional area of the electrolyte within the separator is limited. It is quite possible to fast- charge for a limited time restricted to the Li-ions already presented in the electrolyte withing the electrode. This unssteady state diffusion can last until the Li+ ions are depleted and their supply is limited by the cross-sectional area of the battery.
This mass transfer limitation occurs because the transference number of Li+ is smaller than 1. While Li+ions carry a fraction of the current in the electrolyte, they carry 100% of the current at the electrode; thus depletion of Li+ occurs near the anode, resulting in diffusion limiting current. Any attempt to surpass the limiting current results in solvent decomposition, heating and deterioration of the battery.
So different material battery will have different rate, the typical NCM lithium battery C rating is 1C, and maxium C rate can reach 10C about 18650 battery. the typical LiFePO4 lithium battery C rating is 1C, and the maxium C rate can reach 3C about LiFePO4 prismatic battery.
Battery C Rating Chart
Below chart shows the different battery C rating and their discharge time.When we caculate them, the battery C rating should use same caculation as the same energy.
Battery C Rating Chart
For most of lithium battery, here is the picture to show the discharge curve in different C rate.
Battery Discharge Curve In Different Battery C Rating
For most lead-acid batteries, we should know that even for the same battery, the battery capacity at different battery C rating is different. To get a reasonably good capacity reading, lead acid batteries manufacturers typically rate lead-acid batteries at 20 hours(A very low 0.05C). The following is the discharge capacity of a Trojan 12V135Ah battery at different rates.
Lead Acid Battery Capacity In Different Battery C Rating
How To Calculate The C Rating For The Battery?
A battery’s C rating is defined by the time of charge and discharge.
C-rate is an important information or data for any battery, if a rechargeable battery can be discharged at that C rating, a 100Ah battery will provide about 100A, then the battery has a discharge rate of 1C. If the battery can only provide a maximum discharge current of about 50A, then the discharge rate of the battery is 50A/100Ah=0.5C.
C-rate (C) = charge or discharge current in amperes (A) / rated capacity of the battery(Ah)
Therefore, calculating the C rating is important for any battery user and can be used to derive output current, power and energy by:
1C means 100Ah*1C=100A discharge current available.
1C means 100Ah/100A=1 hours discharge time Capable.
It means the battery can be use for 60minute (1h) with load current of 100A.
2C means 100Ah*2C=200A discharge current available.
2C means 200Ah/100A=0.5 hours discharge time Capable.
It means the battery can be use for 30minute (0.5h) with load current of 200A.
0.5C means 100Ah*0.5C=50A discharge current available.
0.5C means 100Ah/50A=2 hours discharge time Capable.
It means the battery can be use for 120minute (2h) with load current of 50A.
Sometimes analyzer capacity readings are given as a percentage of the nominal rating. For example, if a 1000mAh battery can supply this current for about 60 minutes, read 100%. However, if the battery lasts only half an hour before the cut-off point, the displayed value is 50%. Sometimes a brand new battery can provide more than 100% capacity. The battery can be discharged using an analyzer which allows you to set your favorite C rate. If the battery is discharged at a lower discharge rate it will show a higher reading and vice versa. However, you should be aware of differences in battery analyzer capacity readings for different C rates, which are related to the internal resistance of the battery.
What Are The Effects Of C Rating On Lithium-ion Batteries?
After we caculated above, we know more higher the C rating on a battery, the faster the energy can escape the batteries to power the application. The C rating on any battery depends on its application. Because some electronics require large amounts of power supply thus need batteries with high C ratings, For example, the motorcycle starter, you only needs needs a few seconds to power the motors quickly. But for some application, the discharge time only need need low C rating, Such as the soalr light, you want them to power for whole night or several nights.
What Is The C Rating Of My Battery?
You'll usually find the battery's C-rate on the battery's label and on the battery's data sheet. Different battery chemistries sometimes show different battery C rates.
Generally speaking, Lithium iron phosphate batteries typically have a discharge rate of 1C
NCM batteries typically have a discharge rate of 3C
Lead-acid batteries are generally rated for a very low discharge rate, typically 0.05C, or 20 hour rate.
If you cannot find the battery C rating on the label or datasheet, we recommend contacting the battery manufacturer directly.
In Conclusion
The C-rate is a unit used to identify a current value/discharge time of a lithium-ion battery under different conditions. Since you have had a clear view of what the C rating is , and what it stands for in a battery, you will need to include it in your next selection for batteries to get the best out of what you settle for.
Shingled solar cells are solar cells which are cut into typically 5 or 6 strips. These strips can be overlaid, like shingles on a roof, to form the electrical connections. The strips of solar cells are joined together using an electrically conductive adhesive (ECA) that allows for conductivity and flexibility.
Shingled solar cell
Shingled solar cell – end elevation
This allows the cells to be connected differently to conventional solar panels, in that, there are no busbars (ribbons) required and the solar cells can be joined together resulting in no gaps between the solar cells.
Shingled solar modules can also be wired differently to conventional solar panels. Typically, solar cells in conventional solar panels are wired in a series of strings whereas the solar cells in shingled panels can be wired in parallel configuration.
What are the advantages of shingled solar panels?
Essentially the three key advantages of the shingled solar panel design are they produce more power, improve reliability and are aesthetically pleasing.
1. Increased energy harvest
Higher power per square metre
The shingled solar cells do not require busbars across the top of the cells so more of the solar cells are exposed to sunlight. The cells do not need to be spaced apart like in conventional solar panels so the solar panel area can produce more energy.
Comparison between conventional solar panel and Solaria shingle solar panel
Less energy loss due to shading
Conventional solar panels have the individual cells wired in series so when a part of the solar panel is shaded it can have a significant effect on the level of power output. By configuring the solar cells in shingles, they can be wired in groups and configured in parallel which significantly reduces the losses caused by shading.
Current flow comparison
Below are some examples of shading and losses for a conventional solar panel and a shingled panel. The Shingled panels have greater performance except for the vertical shading example.
Outdoor shade testing over a 70-day period has shown that the shingled solar panel performs between 37 to 45% better than conventional solar panel designs.
2. Better reliability
Low busbar failures
Shingle solar panels do away with approximately 30 metres of busbar and soldered joints that is required on conventional solar panels, so busbar failures are reduced.
Better mechanical performance
Static and dynamic load tests show that the shingle approach is more resistant to failure due to external forces being applied to the solar panel compared to conventional solar panels.
3. More attractive
Shingled solar panels have no visible circuitry which give them clean simple look providing superior street appeal.
Isolation transformer is a device designed to achieve complete electrical insulation between its primary and secondary sides, effectively isolating the circuit. It prevents direct electrical continuity between the input and output, enhancing safety and protecting both equipment and individuals.
1. Isolation Function: The inverter operates by inverting through IGBT power devices, which generate a significant amount of third harmonic and its multiples. These harmonics pose a serious threat to grid pollution. By incorporating an isolation transformer (primary winding in delta connection, secondary winding in star connection), the third harmonic and its multiples can be effectively filtered out. When high-order harmonic currents pass through the primary winding of the isolation transformer, a large inductive reactance is generated in the winding. As a result, the ripple current becomes very small, ensuring that harmonic currents on the secondary side of the isolation transformer are minimized and providing a clean power source for the load.
2. Increased Short Circuit Impedance: In the event of a short circuit fault on the load side, the existence of impedance in the secondary winding of the isolation transformer significantly reduces the short-circuit current. This reduction helps minimize the impact and damage caused by short-circuit currents on the inverter.
3. Providing Neutral Point for Output Power: As the three-phase AC power output by the inverter lacks a neutral point, installing an isolation transformer on the output side is necessary to obtain a neutral point and achieve a 220V AC power source.
4. Complete electrical insulation between the primary and secondary sides, thereby isolating the circuit. Additionally, it takes advantage of the high-frequency loss characteristics of its core to suppress the transmission of high-frequency interference into the control circuit. Isolation transformers are used to float the secondary side with respect to ground, suitable for scenarios with a limited power supply range and short line lengths. In such cases, the system's ground capacitance current is insufficient to cause harm to individuals.
5. The primary function of an isolation transformer is to provide electrical isolation, serving both equipment protection and, importantly, personal safety. It isolates hazardous voltages, with the small capacitance coupling between the input and output of the isolation transformer having a suppressive effect on disturbances caused by lightning, discharges, grid switching, motor starts, and other grid bursts. From this perspective, isolation transformers serve as effective noise suppressors for power sources, providing equipment protection. Regarding personal safety, it ensures the protection of individuals operating the equipment. Since the electromotive force of an isolation transformer is obtained through secondary induction and does not form a circuit with the primary side (which forms a circuit with the ground), it eliminates the risk of electric shock.
At this point, it's safe to assume that everyone knows the products they buy never do their advertised qualities or quantities any justice. Be it the bag of potato chips which has more air than chips or a car that just won’t touch the mileage its manufacturer claims. We're used to stuff performing below expectations and don’t mind it either.
Solar panels on the other hand, are usually excluded from such handicaps. Most consumers go into a solar purchase expecting their panels to produce as many watts as their sticker states, at least in the best of conditions.
Unfortunately, solar panels are no different from any other consumer product in this sense. In fact, don't be surprised at all if you find your panel’s output well below its rated capacity even on the brightest and sunniest of days when they are sparkling clean.
Here's why this happens.
What Can You Realistically Expect from Your Solar Panels
So, that 300 watt solar panel you've been researching probably doesn’t dishout 300 watts of power. But, just what is its realistic upper limit here? The answer depends on a few key factors.
Firstly, a solar panel's rated output is decided through rigorous laboratory testing. These tests are done in perfect conditions devoid of dust, clouds or any other pollutants with light shining directly on the panels at a perfect 90 degree angle. We've covered this in greater detail in our post on solar panel quality.
At first glance, such tests may seem deceptive since ideal conditions are rare, if not impossible. But, the objective of a solar output test is to determine the absolute power a panel can produce, which is an important figure to have.
So, how much of this power can you actually expect to harvest? Solar panels usually achieve only around 80% of their rated peak capacity, but may fall lower. A number of factors contribute to such losses.
What Causes Solar Power System Losses
Losses in usable power start to occur as the light falls on a solar panel. For the purposes of this article, we're going to ignore power loss due to environmental factors such as clouds, shade, dust, etc and focus on losses that are inherent in a solar power system due to its physical limitations. Here's a rundown of how it happens at each level:
Mismatch losses
Also known as the “mismatch effect”, power losses here are caused if solar cells in an array have different properties, resulting in inconsistent voltages. Mismatches can result in serious power losses since the entire system defaults to the output of the lowest performing solar cell.
Besides low power output, excess electricity trapped in the solar module's electric circuit is converted into heat that can further damage the solar modules. Mismatch losses can result in around 2% power loss.
Temperature loss
Solar cells perform best below 25 degrees celsius, which is also what the temperature they are tested against. The catch here is that these figures refer to the temperature of the cells and not that of ambient air surrounding the panels. So, the panels themselves can get much hotter than 25 degrees even if the ambient temperature is a cool and breezy 20 degrees.
A solar panel's power output can drop drastically as it gets hotter than 25 degrees. Power loss due to heat is measured as “Pmax”, which tells us how much a solar panel's electricity production drops per degree rise in temperature. For example, if a solar panel's Pmax is -0.45%, then that's how much electricity we lose per one degree celsius.
Temperature accounts for the majority of a solar panel's output losses and can range from 10% to as much as 25% in very hot conditions. Since mean temperature in most Australian cities can reach well over 30 degrees celsius during summer months when we have the most sunlight, the solar panels will also experience the greatest power loss here.
Light-induced degradation (LID)
LID typically occurs during the first few days after a solar installation and causes power loss due to build up of boron-oxygen compounds in the solar cell's silicon base. Some solar cells are more predisposed towards LID than others. LID accounts for 0.5% to 1.5% of power loss in photovoltaic systems.
P-type monocrystalline solar cells have higher oxygen content and are doped using boron and accept electrons, which makes them more susceptible to LID.
Multicrystalline solar cells are not as efficient as monocrystalline cells, however have less oxygen making them resistant to LID. Similarly, N-type silicon wafers are doped with chemicals that release electrons making them impervious to LID.
Cable and wiring losses
Solar panels are a collection of photovoltaic cells stacked in an array. These arrays feed into a wire that runs from the panel into the inverter. Since no wire is fully efficient, part of the power flowing through it is lost as heat.
For most solar power systems, cable related power degradation accounts for around 2% of the system's total loss, which can be brought down to 1% by using thicker wires or positioning the system such that it requires shorter wires to reach the inverter.
DC to AC Loss
Solar panels produce DC current that's unusable by household appliances. A solar inverter then converts that DC power into usable AC electricity which is fed into your home’s electrical circuit and the grid.
Since solar inverters are around 93% – 96% efficient, a portion of DC power being fed into them will be lost as heat. The exact amount of electricity lost will depend on your inverter make, and whether it’s oversized or not.
Oversized inverters (or, inverters that are rated for a higher output than the solar power system's total output) are more efficient than those that are matched to their panel's output.
Inverter Clipping
Inverter clipping happens when the DC power input from the panels is greater than its rated capacity. In such a case, the inverter “clips” or derates the overall output to match its own capacity, causing a loss in power.
How Can You Maximize Your Solar Power System's Output
The reasons for power loss we've discussed above are mostly unavoidable, because physics. However, we can also bring down such losses by designing efficient solar power systems.
For example, selecting solar panels with low or no LID potential, using sufficiently thick wires and cables, strategically sizing the inverter to mitigate clipping and positioning the solar panels such that they receive as much direct sunlight as possible can all help increase the system's output.
Marching towards August, the temperature remains high. While we are standing with the continuous summer heat, are you curious about the 'feelings' of your home PV equipment? Can they survive under ongoing high temperatures? Let's find out!
Since PV solar panels do not contain circulating water, they can evacuate heat from each side of the panel, so they do not bear the risk of overheating. However, high temperatures can influence the efficiency of solar panels. So, how can we test solar panels for power output? The standard practice is at 25°C.
If a panel is rated to have a temperature coefficient of -0.34% (PERC) per °C, that panel's output power will decrease by 0.34% for every degree the temperature rises above 25°C (77°F). Although that number may sound small, the surface temperature of a dark roof in summer can be significantly higher than 25°C – imagine an asphalt road surface on a hot summer day. The small percentage of output power loss for each degree of heat compound.
Choosing the right solar panels and the right solar system size, together with high-quality installation, will help reduce the effects of heat.
So, be relaxed, be prepared, and enjoy your summertime!

As the demand for clean energy continues to grow, the use of high-quality mid clamps and end clamps will remain crucial in supporting the expansion and sustainability of solar power.
Solar flood lights are a marvel of modern engineering, incorporating cutting-edge technology to deliver reliable and eco-friendly illumination for outdoor spaces. These lights work successfully under a variety of settings thanks to a combination of advanced technologies and components that are specifically engineered to capture solar energy. Solar flood lights’ technology not only improves their functionality but also highlights how important they are becoming to sustainable energy solutions.
The photovoltaic panel is the cornerstone of solar powered flood light technology. These panels ultilize semiconductor materials, typically silicon, to convert sunlight into direct current electricity through the photovoltaic effect. Advances in PV technology have significantly increased the efficiency of these panels, enabling them to capture more solar energy even in low-light environments. This efficiency id crucial for ensuring that the solar flood lights can store sufficient energy during the day to provide consistent illumination throughout the night.
Energy storage is another critical aspect of SLD solar flood lamps technology. The electrical energy generated by the PV panels is stored in high-capacity batteries, commonly lithium-icon, known for their durability, fast charging capability, and long operational life. These batteries are designed to store enough energy to power the flood lights overnight, even during cloudy or rainy days. The inclusion of smart battery management systems further enhances the reliability of these outdoor solar lights by optimizing charging cycles and extending battery life.
The use of LED technology is integral to the energy efficiency and longevity of solar flood lights. LEDs are highly efficient, consuming less power while providing bright, consistent illumination. Their low energy consumption means that more of the stored solar energy can be used to power the lights for extended periods, making them ideal fro overnight use. Additionally, LEDs have a long lifespan and produce minimal heat, reducing energy waste and improving the overall durability of the lighting system.
Solar flood lights are also equipped with advanced control systems that add to their functionality and user convenience. These systems often include sensors that detect ambient light and motion, allowing the lights to automatically activate at dusk and deactivate at dawn or when no motion is detected. More advanced models may offer remote control and programmable settings, enabling users to customize the lighting according to their specific needs. This level of control ensures that solar flood lights are not only energy-efficient but also adaptable to various environments and user preferences.
