Nowadays most customers are conscious. Not just about consumption, they are concerned about how their choices impact our environment. From what we eat and what we wear to how we travel and what to use, people started making shifts in their choices. The world is shifting towards renewable energy sources. On-grid solar inverts have become popular in the last decade. It has become a go-to option for many residential, commercial and industrial purposes. Sustainability alone can't make that great impact towards the increased adoption of on-grid solar inverters. It is also because of the advanced features, reliability, cost, and lifespan of on-grid inverters. In this blog, we will discuss the average lifespan of on-grid solar inverters and ways in which you can maintain them properly.
Working of On-Grid Solar Inverters
On-grid inverters function by converting direct current (DC) electricity generated by solar power into alternative current (AC). In this way, the variable DC output from solar panels gets converted into usable AC power. While off-grid inverters operate independently from the grid and require battery storage while on-grid inverters function in conjunction with the grid. Also, maximum power point tracking is possible. On-grid inverters make the most effective use of energy harvested from solar panels. This is made possible by functioning solar panels at their peak power point. Any surplus electricity generated will be sent back to the grid.
Types of Solar Inverters & Their Lifespan
As on-grid solar systems strongly align with sustainability, the demand for the system surged in many parts of the world. Different types of on-grid solar inverters are now available in the market. The most common types of on-grid solar panels include:
String Inverters
These types of inverters are very common. String inverters are widely used in residential and commercial installations. It collects DC current electricity produced from a series of connected solar panels (strings). This DC power is then converted to AC current. These are a cost-effective option for small to medium installations.
They are not only cost-effective but are also easy to install and maintain. When it comes to these types, the lifespan of on-grid solar inverters lasts between 10 to 15 years.
Microinverters
These small devices are installed directly on each solar panel. Microinverters perform independently and make use of maximum power production. These inverters are installed behind each solar panel. As these inverters perform independently, it won't affect the power output of other panels even if any panel is malfunctioning. Microinverters have a longer lifespan and last around 25 years.
Central Inverters
Central inverters are mostly used in large-scale solar power systems. These types of inverters function by combining the functions of a traditional solar inverter and a battery inverter into a single unit. When it comes to the lifespan of the on-grid solar inverter of this type, it lasts between 5 to 10 years.
Factors that Impact the Lifespan
While the type of inverter plays a significant role in determining its lifespan, several other factors also come into play. These include:
Installation & Positioning
Proper installation and positioning of the inverter play an important role in ensuring the longevity of on-grid solar inverters. Inverters should be installed in a shaded, well-ventilated area, protected from extreme temperatures and weather conditions.
Temperature & Weather Events
Extreme temperatures, humidity, and weather events like lightning strikes or floods can significantly impact the lifespan of solar inverters.
Grid Voltage & Power Quality
The quality of the grid voltage and power can affect the lifespan of on-grid solar inverters. Inverters that are exposed to poor power quality may degrade faster. This is a crucial factor that impacts the longevity of the systems.
Maintenance & Cleaning
Regular maintenance and cleaning of solar inverters can help extend their lifespan. This includes checking for dust, debris, and pests, as well as performing software updates.
Average Lifespan of Solar Inverters
Based on the factors mentioned above, the average lifespan of on-grid solar inverters can vary. However, here are some general guidelines:
- String inverters: 10-15 years
- Microinverters: 20-25 years
- Central inverters: 5-10 years
It's essential to note that these are general estimates, and the actual lifespan of a solar inverter can vary significantly depending on the specific conditions in which it operates.
Extending the Lifespan of Solar Inverters
While on-grid solar inverters have a finite lifespan, there are steps you can take to extend their durability. A few things you can consider are as follows:
Regular Quality Checks
It will be better to do regular checks and maintenance tasks. This ensures the inverter operates efficiently.
Proper Installation
You need to ensure that the inverter is installed correctly. Installation should be done considering factors like temperature, humidity, and weather conditions.
Monitoring & Testing
Regularly monitor and test the inverter to identify any potential issues before they become major problems.
