Solar power energy can save you money in the long run. However, setting it up and running it effectively requires a lot more than the solar panels themselves.
One key component in any solar energy system is the solar power inverter. Without this, solar power gathered from the panels cannot even be used as electricity. How does this happen? But most importantly, how can you choose a good solar power inverter? We’ll attempt to answer these questions below.
Why are solar power inverters important?
As mentioned, solar power inverters are essential components in any solar energy system. Solar inverters transform direct electricity (DC) to alternating current (AC). The latter is the form of electricity that can be readily and safely used in many homes and establishments.
See, when the sunlight hits the solar panels, the photovoltaic cells can only generate direct current which only flows in one direction. If you are just powering up your laptop and other mobile gadgets, then this form of electricity will do. But it is impractical and dangerous to run through the entire home. Thus, the use of inverters became very important to ensure the usability and efficiency of power conversion.
Now that you know why it is important, you might be wondering how you can choose an inverter out of all the inverter types and models available in the market today. In the next section, we will share tips on how to choose one that is suited for your desired setup and budget. So, read on.
Step One: Know Your Type
Buying a solar power inverter is a huge investment. Before you head on to the store or talk to your provider, it is important to do your research first. Your research can teach you many things, but the first thing you should learn about is the type of inverter you need. There are five different types, namely:
For sites where power consumption runs less than 1MW, then string-type inverters are perhaps the best. A row of panels is attached to a single inverter, making it an efficient choice for everyday homes.
For locations that use more than 1MW of power, a central inverter is a sound choice. They work the same way as the string inverters in that they connect to rows of panels. But unlike the previous counterpart, this type can support more power.
If you are living in a city or some other place where the sun is hindered by shade, getting micro inverters is the most practical choice. Each micro inverter connects to an individual panel, so if a side gets covered by shade at a particular time of day, your overall power generation is not compromised.
These inverters do not only transform electricity, but they are bidirectional components that work as chargers as well. When you choose them, the benefit is massive since they provide continuous power load.
If you need the efficiency of string inverters, but also want the practicality of micro inverters, then power optimisers can give you the best of both.
Step Two: Identify the Specifications You Should Look For
The next things you need to study are the important specifications you should look for in an inverter. These specifications include the following:
To determine which specifications are suited for you, it is recommended to talk to professional providers for they are better-equipped to determine these factors than lay people. Once you have determined the specifications you need, the rest of the steps will be easier.
Step Three: Compare Different Brands and Types
Search online and offline for stores or providers that can supply you with the inverters you need. Once you start shopping, you can now compare prices, quality, make, and many other factors.
Step Four: Check Their Parameters
Solar power inverters cannot produce electricity, so you need to make sure that the parameters are just right. These parameters include their ability to handle the generated power, the power needed in the household or building, and so on.
Step Five: Identify the Accessories You Will Need
Basic inverters do one single thing – transform collected power into usable electricity. But if you have a bigger budget, you might want to look into purchasing inverters that come with specialised features. For instance, some inverters nowadays come with tracking chips to safeguard their security.
Solar power inverters and panels are big investments, and sadly, crimes targeting these valuables are not unheard of. So, if you want to keep them safe, make sure to invest in security features like the ones mentioned here.
Step Six: Invest in Weather-Proof Features
Another thing you must look into are weather-proof features that can stand harsh rains, storms, and heat. Most inverters come with 10-year warranties, but to ensure their longevity, make sure they can survive the environment you are going to expose them to.
