Are you really getting value for your money with your Solar PV System? Is there a difference in your electricity bill after installing this sophisticated Solar PV System. Well, is it may be a good idea to start from identifying your current setup when we attempt to answer this difficult question. But as we learn more about these issues. We are however not supposed to go and change our inverter settings. This is not recommended. Ultimately, the idea is to learn the tricks and share them with your service provider. Let’s then take deep dive.
Identifying your current installation setup
There are many inverter brands out there, but they all work on similar principles. For example, all inverters have a display where you can see the current operating mode of the inverter. The display will show four elements e.g. “Solar Array”, “Battery”, “Grid/Utility” and “Load/House consumption”. The more expensive the inverter is. It will give more information like power in Kilo Watts (kW). Some will show arrays or even graphic presentation of power consumption. Like in the example of this Deye inverter below.
Even if you have to look at a Luxpower inverter below. It also displays the four elements: Solar Power, Grid, Batteries and Load. As you can see.
Since, you can now see that the Solar panels connected in Figure 2. It is going to be easy to identify the current installation setup. What do we mean about “installation setup”? Well, you need to identify what source of power is your PV System using to power your house or load. I am sure you will agree that if you use the municipality power as little as possible. You will save money. Yes, absolutely by using the Solar power and batteries as you main power. You are almost there!
How do you get an automatic saving?
Well, you are moving the right direction by using the Solar and battery power instead of the municipality power. To achieve this illusive saving is not so straightforward and easy. There are other few factors that needs to be considered. Like the total maximum load in the house. What is this “maximum load” in the house? It is the maximum power that the appliances in the house will consume. To make is worse this must be compared to the maximum power capacity on the inverter. It is just to ensure your Solar PV system does not become overloaded and switch-off. As a general rule the power produced by your Solar PV system should at least supply 40% of your monthly power consumption bill every month. I think that will be value for money. Don’t you think?
