How Solar Inverter Works & It’s Applications

Solar Inverter is the ultimate device that can alter the direct current output of the heat consumption by solar panels into the alternate current. The electric elements in the solar inverter circuit are responsible for the energy and current conversion.

How Does A Solar Inverter Work?
Where inverters are used, the major need is for solar energy getting used as an all-time power source from the battery inverter system. It requires MOSFET Driver, PWM inverter IC, Bridge-MOSFETs Drive, Solar Panels, Steps Up Transformers and batteries to function properly. Photovoltaic cells help in the conversion of solar energy into electrical energy. During the day-time, the energy converted is stored for later use so that the homes requiring electricity can use this solar energy with the help of the inverter.


The photovoltaic solar panel’s output of direct current is converted into an alternate current that goes straight to the connected commercial grid. Using the PWM inverter IC and MOSFET, the solar energy stored in the photovoltaic cells gets altered into the alternate current. This conversion allows the electricity to power the systems. Voltage amplification, performance to the circuit and the flow function are controlled by the solar inverter as it keeps the operating current flow parallel.

Since solar energy proved to be a great source of fuel and energy for machines such as cars, home appliances etc, solar inverters have varied from the basic systems to advanced technology. Here are a few of its applications:

1. Micro Inverters
As is it named, microinverters tend to be small and portable which provide equally as much output and performance as other inverters. They also have all the central inverter features. These inverters are not only used on a wide scale commercially but also on a residential ground as they are capable of monitoring each panel’s performance. These are very easy to install but are costly as compared to other types of inverters as they can be sold through manufacturers like AC Modules.

2. Battery Based Inverters
These types of inverters are highly essential as they are bi-directional in nature. The battery charger and the inverter are both capable of providing alternate current power to heavy loads during power cuts. Depending on their design and UL rating, these inverters can be off-grid, grid-tied or grid-interactive. The major advantage of these inverters is that they can provide continuous current despite the grid condition. Keeping the batteries charged, battery-based inverters easily manage the energy supply between the grid and the array.


3. String Inverters
In this type of solar inverter, each panel gets installed on a string in a row. Likely, all the strings are attached to one main string inverter. Through the solar panels, each string carries the direct current to the string inverter and changes it into an alternate currency that can be later used as electricity. Since this type is quite primeval, it is easy to install as the panels are faced in one direction on a plane surface with no shading issues at all. It is not as flexible as the battery-based inverters because the entire string panel struggles with performance if one of the panels is shaded. But string inverters are cheaper than the micro-inverters.

4. Central Inverters
The difference between string inverters and central inverters is that of the size. These two are quite similar but central inverters tend to be larger in size and produce much more energy as well. In this type, the strings are all in a combiner box tied and attached together. This box carries direct current straight to the central inverter where is it is converted to alternate current. There are not many components in the systems but a common combiner box and a pad is a must.

Victorian residents will be able to get solar panels for 50% less following a new Local Government program

Victorian residents will be in a position to set-up solar panels in their home properties for 50% less under a new state government program ($1.24 billion) as administered by the Andrews government.

The Victorian government announced last Sunday that it will spare  $4,550 in advance to set up the rooftop solar panels and homeowners would be ordered to contribute 50% of the value within 4 years from the moment of installation.

The respective solar panels program is open to owner-residing homes and properties whose value doesn’t surpass $3 million and the total household income amounts up to $180K.

Within this program, solar panels will be placed on approx. $650K over the next decade.

Victorian Premier Daniel Andrews has stated that the plan aims to assists thousands of homes trim down their energy expenses by $890/year. He further added that with privatization regimes, the costs should be significantly reduced but this was an empty promise that is yet to take place. He emphasized that at this point, there is a new state plan on the rocks that is more practical based on some concrete evidence of what will come out of it.

The program aims to save $2,225  on average for setting up a typical 4kW solar panel.

The state administration has made a promise that in the event of its re-election, the program would be extended from July 2019 to enable homeowners to pay back the loan taxes free.

Solar Victoria”, an autonomous agency will also be employed to supervise the program and ensure that proper standards and safety measures are followed. 

The state government has also stated its plans to dish out $9 million for the employment of 4.5K electricians to set up the solar sets.

Mark Wakeham, Environment Victoria CEO, has expressed his satisfaction with this initiative as it occurs after times of troublesome conflict regarding energy expenditures in Australia. He added that with this plan, Victorian homeowners will be able to regain control of their energy expenses and that every homeowner who wishes to use solar energy will be in a position to afford it under this regime. He elaborated that introducing 2K megawatts of solar energy that exceeds previous expectations, will trim down energy bills for Victorian households and properties by allowing new power to flow into the power grid.

However, voices of opposition like David Southwick have stated that the regime was just an idea bubble and nothing else. Supporting his views further, he said that the plan announced to us is just going to dish out money without any extensive reasoning to back such an investment up and no consumer security being present.

Top 10 Solar Energy Uses

Solar lights, Solar heating, solar charging…it has now become quite common for us to hear such terms on regular basis but not many people are aware of this incredible natural gift we can use to make our lives better and easier.

Solar energy is that bright and radiant energy emitted by the sun. This energy is converted into electricity and heat energy in order to supply power to homes, industries, offices, and hospitals. Since the Sun is capable of providing us light and heat, solar power is a technology that can serve the Earth well. We no longer have to be completely dependent on other resources and fossil fuels. From solar transport to chargeable technological devices, there are countless possibilities of how far can we go with the use of Solar energy.

Top 10 Uses Of Solar Energy:

There are many things that solar energy helps us with. Here are the top ten uses of solar energy:

1. Solar Lights

Ever since solar panels were designed, it became very easy to install these panels into almost everything we desire. From lights, transportation and machines to swimming pools, heaters and wearable accessories such as watches, as well as tech items like calculators, laptops, cell-phones, solar power have it all covered. Solar lights are a great deal nowadays as people are swiftly shifting their energy source to solar power. From street lights to indoor lights, solar power is capable of lighting up your house with no costly bills waiting to be paid. All it takes is the installation of solar panels on the roof of your house.

2. Solar Heating Systems

In the coming decades, it would not be a surprise to see how solar energy is practically used everywhere to heat up homes, water, pools, and whatnot. Need some warmth? Solar energy panels have got your back.

3. Solar Electronics

Not only solar energy is used in heating or powering homes and pools, but now it is immensely used in all sorts of electronic devices. Such as home appliances like dryers, thermostats as well as music speakers, watches, trackers, tablets, solar visor radios, freezers, and flashlights.

4. Solar Transport

Trains and planes that require fuel and electricity are no longer relying on other resources. Solar panels are used in trains and as well as planes for people to travel more efficiently. It is also getting used in cars instead of gas or fuel.

5. Solar Fabric

Is it believable that solar panels are made flexible enough to now get attached to clothes? Yes, it is. The solar fabric would soon replace the heavy clothing people use to stay warm up in the Northern parts of the world. Soon enough, the solar fabric would be common and affordable for everyone to buy and where to stay warm without the need for excessive and large clothing.

6. Solar Paints

Solar paints are not officially marketed yet but they are in existence. Solar cells are used in a nano-scale photovoltaic mixture exposed to sunlight on a conducting material that can be sprayed and painted on almost every surface. If solar paints are used on buildings, it will be magical to watch them dry within seconds as soon as the sun hits the sky.

7. Solar Ventilation Systems 

Air-conditioning has been a luxury in the hot parts of the world. The need to keep homes ventilated and the air conditioners running is the ultimate need. So it is now a blessing to see the solar air-conditioners hitting the markets. Not only can solar energy be used to keep buildings ventilated but it can also be used in heaters and air-conditioners.

8. Solar Chargers

Solar chargers made a massive change in the industry of tech items and tech appliances. From rechargeable flashlights, watches and cell-phones to other rechargeable batteries, solar charges are now the new high in the solar world.

9. Solar Environment

If fossil fuels and other resources are entirely replaced by solar energy, the environment would get better and global warming might reduce as the amount of CO2 present in the air would be altered to a great deal. Greenhouses that use solar energy do not produce as many gases as compared to other resources. Water pollution stays under control as well as noise pollution since the solar panels do not create any noise either.

10. Solar Economy

Not only human effort is required in creating solar panels but it is also required in installing those panels across the globe in houses and buildings. This creates room for jobs and employment in the economy. Thus, solar power helps people with their employment, comfort and efficient living.
