Difference Between Monocrystalline and Polycrystalline Solar Panels
Solar power, once a sideline of carbon-based energy, is growing rapidly, powering more homes than ever before. Therefore, it pays to scrutinize all aspects of your solar system, especially the choice between monocrystalline or polycrystalline solar panels. Performance, efficiency and durability depend on your choice of solar panel type. In this article, we will introduce the differences between monocrystalline and polycrystalline solar panel.
Hybrid Solar Inverter vs. Off Grid Inverter
An inverter is often called the brain of a solar system because it converts solar radiation into useful energy. There are different types of inverters available in the market: on grid inverters, off-grid inverters and hybrid inverters are the types available in the market. In order to choose the right inverter, it is important to list your needs. The one you choose depends mainly on your solar installation and energy consumption.
Power Inverter vs. UPS
Today, electricity has become a necessity. All most all of our day to day works requires electricity. To smoothly run these devices even after the blackout of electricity and get uninterrupted, electrical power systems are discovered. UPS and Inverter are an example of such discoveries. Although these devices work for the same intention, however, people remain confused with the difference between a UPS and an inverter.
Solar Power vs. Petrol
Fossil fuels are a finite energy source, solar panels harness the sun’s energy and will always be available. Either way, one thing is clear. Solar power has nothing to do with petrol. Let us compare the two and why solar is seen as a replacement for petrol.
Differences Between UPS Inverter and Inverter
Modern society is heavily dependent upon appliances that run on electricity. When there is a power failure, the power supply of these appliances is cut off and they stop working. In order to solve these problems of power failure and no power availability, ups inverter and inverter are designed. Both inverter and ups are used to provide standby power supply for electronic equipment in case of power failure.
Solar Generator vs. Gas Generator
With this year's home order and social distance, we all rely more on the power supply at home. Finding a suitable backup power source for your home is an important safety measure if the power grid fails, breaks down or people are trapped in their homes. Two of the most popular power solutions are solar generators and traditional gas powered generators. Each option has its advantages, but solar generators are more cost-effective, resilient and sustainable than gas generators.
Difference between Solar Central Inverter and Solar Micro Inverter
There are many advantages of micro inverter over central inverter, the first advantage is that micro inverter is performing much better in case of shading, as if there will be a partial shading on a part of our solar system due to chimneys or trees, the overall output power of the string will not be affected, but only the shaded solar panel output power will be affected, while in central inverter the overall output power of the string will be affected, and there will be much power loss. The second advantage is the capability of micro inverter to track maximum power point for each connected solar panel, resulting in high efficiency and output power from the solar system.
Wind Turbine vs. Windmill
A wind turbine is a mechanical device that uses the kinetic energy of the wind to generate electricity, mainly for commercial use. Wind turbine technology is one of the most reliable and cost-effective technologies for generating large amounts of electricity. It is a clean energy source that uses wind power without producing harmful gases. Windmill is one of the earliest and most efficient forms of man-made electricity. It uses wind power to generate electricity and uses it for many functions such as pumping water, sawing wood, grinding grain, etc.
Difference between Series and Parallel Inverter
The difference of series inverter and parallel inverter is that they use different oscillation circuits. The series inverter connects L, R and c in series and parallel inverter connects L, R and c in parallel. Series Inverter vs. Parallel Inverter The load circuit of series inverter has low impedance. The voltage source power supply is required and the large filter capacitor shall be connected at the DC power terminal in parallel. If the inverter fails, it is difficult to provide protection because of large surge current. The load circuit of parallel inverter shows high impedance and the current source power supply is required. The large reactor shall be connected at the DC power terminal in series. If the inverter fails, it is easy to provide protection because the large inductor can limit the current so as to avoid large impact.
Difference between On Grid Inverter and Off Grid Inverter
Inverter refers to a device that converts DC power (such as storage battery) into AC power (usually 220V, 50Hz sine wave). Grid tie inverters are generally used in the system of large-scale solar photovoltaic power stations. Many parallel photovoltaic strings are connected to the DC input of the same centralized inverter. The off grid inverter can work independently after leaving the grid, which is equivalent to forming an independent small grid. This article will introduce on grid inverters and off grid inverters, discuss the working principles of off grid inverters and on grid inverters, as well as their differences.
Difference between Inverter and Transformer
Inverter is commonly used in the industrial field and its main function is to convert the current in a certain way. Transformer is a device that can change the AC voltage based on the electromagnetic induction principle. It is mainly composed of primary coil, secondary coil and iron core (magnetic core). To make it easier to understand the inverter, hereby the difference between inverter and transformer will be discussed.
Difference between Sine Wave and Square Wave of Inverter
Inverter is a device that can convert DC (direct current, such as storage battery) into AC (alternating current/mains), which is widely used in air conditioners, computers, lighting and other electrical appliances. Especially on traveling or working, inverter can generate alternating current by being connected with batteries, so as to supply power for the instruments or electrical appliances requiring alternating current for use. It is very easy to change alternating current (AC) into direct current (DC), and with only a diode, the simplest rectifier circuit can be formed. However, it is not that simple to change direct current to alternating current. The magnitude and direction of alternating current will change periodically over time. The mains power we use shows regular changes of sine function.
Difference between Generator and Inverter
Generator is an electromechanical device that generates electricity by transforming mechanical energy into electric energy. It generates electricity based on the electricity and magnetism work rules. It is driven by the wind turbine and hydraulic turbine of the system. The electricity generated by the system is for power station application and industrial application as main AC power. Inverter is a power electric device that can convert one current into another current. This device is mainly used to transform DC into AC. The inverter takes AC directly from AC source and converts it into the DC by rectifier. The converted DC is used to charge the battery. At the same time, as AC is used in the industrial and household system, the DC from the battery will be converted into AC by the inverter. This system can be used to supply power for household electricity system in case of power failure. The inverter does not need external power to support its work. Although both the inverter and generator can improve the work efficiency, their functions are totally different.
MPPT vs. PWM Solar Charge Controller
In the solar off-grid system, the photovoltaic controller is to store the electricity generated by the photovoltaic module in the storage battery after transformation. In addition, it also has the functions of protecting the storage battery and preventing the battery from overcharging. At present, there are two main technical routes of the solar charge controller: Maximum power point tracking (MPPT) and pulse width modulation (PWM), both of which have its advantages and disadvantages, so users can select according to different scenarios.

Differences between Central Inverter and String Inverter
Central inverter: The power is between 100kW and 2500kW. With the development of power electronics technology, the string inverter is having an increasingly bigger market, and the central inverters below 500KW have already basically been eliminated from the market. The power device adopts high-current IGBT. The system topology adopts DC-AC first-level power electronic device to transform the full-bridge inverter. The latter stage is generally connected to the double-split power-frequency boost isolation transformer. The protection level is generally IP20. It has a large size and is vertically installed indoor.
Pure Sine Wave vs. Modified Sine Wave Inverters
Pure sine wave inverters output the true sine wave AC power which is the same as or even better than the power grid we use every day since there is no electromagnetic pollution. Pure sine wave inverters, with high efficiency, stable sine wave output and high frequency technology, are suitable for all kinds of loads, which can not only power any common electrical equipment (including phone, heater, etc.), but also run the sensitive electronics or appliances (like microwave, fridge, etc.).
