In recent years, several environmental issues, such as climate change, pollution, deforestation, global warming, and the depletion of the ozone layer have come to light. As a result, people across the world are doing their bit for the planet, and one such key step has been switching to renewable energy sources. In India, solar energy has been the popular choice for many, especially as our country receives ample sunlight throughout the year.
But when it comes to solar power plants, many of us are only familiar with PV panels. However, there are various components that complete a solar setup, including a solar inverter. And while a solar inverter works just like a regular inverter, it is indispensable to solar power systems. Are you wondering why? Well, keep reading to find out more about solar inverters!
The Basics of a Solar Inverter and How it Works
A solar inverter is an electrical device that converts Direct Current (DC) into Alternating Current (AC). In simple terms, it takes the energy generated by the solar panels and transforms it into usable electricity, so you can power appliances like lights, fans, air conditioners, washing machines, printers, fax machines, and more.
Here’s a detailed look at the process:
- First, the solar panels absorb sunlight and transfer it to the photovoltaic (PV) cells. The cells then create an electric field, thereby generating Direct Current (DC).
- Next, the Direct Current produced by the panels is sent to the solar inverter. However, if you install an off-grid solar power system, it is first transferred to the solar battery. And when you wish to utilize the stored electricity, it is then sent to the inverter.
- When the solar inverter receives electricity in DC output, it runs it through a transformer to convert it into Alternating Current (AC) output.
- Lastly, the AC output is transferred to the primary connection switch so you can start powering your home or workplace with clean energy.
Although the primary function of a solar inverter is to convert DC into AC, it also helps maximize power output and helps ensure that the system operates safely. Additionally, you can also keep track of the PV plant’s efficiency and performance as most solar inverters now come with remote tracking and other smart features.
Which Solar Inverter Technology Should You Choose?
Once you start exploring solar inverters online or in stores, you will find that they are available in two different technologies, namely Pulse Width Modulation (PWM) and Maximum Power Point Tracking (MPPT). Thus, in addition to choosing an inverter type (on-grid, off-grid, or hybrid depending on the PV plant), you also need to select a technology. And since this can be tricky, here’s a brief look at both the options:
- Pulse Width Modulation (PWM) (H3 Tag) – Solar inverters equipped with Pulse Width Modulation (PWM) technology have been in use for numerous years. The technology is low-cost, efficient, and, most importantly, tried and tested. Plus, it is best suited for small to medium-sized solar power systems like those installed in households.
- Maximum Power Point Tracking (MPPT) (H3 Tag) – MPPT technology, although popular, is new in the Indian market. However, it has gained massive traction as it offers 30% more efficiency compared to its counterpart. This also makes MPPT solar inverters slightly costlier, but you can easily use them with all solar PV systems, especially large-sized ones.
So, which one should you choose? While most of you might be thinking of opting for a solar inverter equipped with MPPT technology, it is first important to evaluate your unique requirements. This includes your daily electricity consumption, the type of solar power system, and your budget so you don’t go overboard. Moreover, make sure you go for a reliable and trusted brand like Luminous that offers only high-quality, efficient, and affordable solar inverters. Visit the website today to know more!
