This program is oriented toward photovoltaic power generation systems. In photovoltaic systems energy is firstly obtained in DC and, to convert it to the same type of energy we received from the grid, we need to use inverters.
There are three types of solar inverters available.
These types are:
- String inverters
- Power optimizers + inverter
- Microinverters.
This program is focused on string inverters. In this type of inverter, solar panels are distributed on what's known as a Maximum Power Point Tracker (MPPT). As the distribution of photovoltaic panels increases, the distribution becomes more complicated.
This program aims to help efficiency in the distribution of solar panels in inverters (MPPT).
Make sure your Python version is Python 3.7 or above. Run the following command to confirm
python --versionHere is an example of how you can install and run this app.
- Clone the repo
git clone https://github.com/henfrydls/PVsolar.git
- Change directory
cd PVsolar - Install required libraries
requirements.txtpip install -r requirements.txt
- Run the app
python visual.py
Let's suppose you have the following configuration:
- 1 string type inverter: Canadian Solar Comercial inverter 75kW (8 MPPT, 16 inputs) CSI-75K-T480GL02-U
- 160 Solar panels: Canadian Solar 590Wp HiKu6 Mono 590W
Notice that this configuration keeps our DC/AC ratio to 1.259. Learn more about DC/AC ratio here Ideal Ratio
A String is a certain amount of solar modules connected in series. It's important to know our maximum string size based on our inverters, solar panels, locations, etc. Hopefully, most PV sizing software nowadays includes this calculation How to Calculate PV String Size
The maximum number of modules is 18 modules in series based on a certain location
After all previous data is determined the question is "How can I optimize my energy generation?" and here is where PVsolar comes into action.
Just fill in the required information and PVsolar will give you the best matches for your case of study.
The app will always prioritize the best result. In this case, your best match will be to wire 7 strings consisting of 18 modules in series and 2 strings of 17 modules.
In case you need more configurations, the app will always give you all matches found on the specified intervals.
This type of MPPT distribution as of now is not available in most software destinated for Photovoltaic systems, although some of them can include some features of it. I hope to see most software coming with this feature shortly.
