How to study the effects of photovoltaic shading using a photo survey or the solar diagram
How to select and place the PV modules and inverters from the extensive library
How to activate, size and configure the storage system and the energy metering devices
How to generate the wiring diagram of the photovoltaic system automatically
How to perform the financial analysis and the business plan of the photovoltaic system
Step 1: Import or create a 3D/BIM model of the building or site
The first step is to import or create a 3D/BIM model of the building or site where the photovoltaic system will be installed. You can do this in different ways:
You can import an existing 3D/BIM model from a DXF/DWG file or an IFC file from other software such as Edificius, Revit, ArchiCAD, etc.
You can create a new 3D/BIM model from scratch using the parametric objects provided by Solarius PV, such as roofs, walls, windows, etc.
You can use the integrated Google Maps service to geolocate your project and import satellite images and terrain data.
Once you have your 3D/BIM model ready, you can use the smart snapping tools to place your PV modules on any surface, such as roofs, facades, pergolas, carports, etc. You can also adjust the orientation and inclination of the modules according to your design criteria.
Step 2: Calculate the solar irradiation data using Meteonorm or PVGIS climatic databases
The next step is to calculate the solar irradiation data for your project location. Solarius PV allows you to do this automatically by using one of the following climatic databases:
Meteonorm: this database provides worldwide solar irradiation data based on more than 8,000 weather stations and satellite images.
PVGIS: this database provides solar irradiation data for Europe, Africa, the Mediterranean and South-West Asia based on satellite images and ground measurements.
You can also import your own solar irradiation data from other sources or direct measurements. Solarius PV will use this data to estimate the photovoltaic energy production of your system over an annual, monthly or daily basis.
Step 3: Study the effects of photovoltaic shading using a photo survey or the solar diagram
One of the most important factors that affect the performance of a photovoltaic system is shading. Shading can be caused by fixed obstacles (such as walls, trees, or pillars) or by circumstantial events (such as cloudy sky or smoke). Shading can reduce the solar irradiation and the output power of the PV modules, and even cause overheating and damage to the PV cells. Therefore, it is essential to study the effects of photovoltaic shading and avoid or minimize them as much as possible.
Solarius PV provides you with two methods to evaluate the photovoltaic shading:
The photo survey method: this method allows you to estimate the shading caused by long-distance obstacles (such as mountains, hills, buildings, etc) by using a simple photographic survey of the horizon. You can use a digital camera or a smartphone to take a panoramic photo of the site and import it into Solarius PV. The software will automatically detect the horizon line and calculate the shading factor for each month of the year.
The solar diagram method: this method allows you to estimate the shading caused by near obstacles (such as chimneys, walls, antennas, etc) by using the solar diagram of the site. You can draw or import the obstacles on the 3D/BIM model and Solarius PV will show you how they affect the solar path and the irradiation on the PV modules. You can also check the shading effect for any hour of any day of any month.
By using these methods, you can optimize the position and orientation of your PV modules to reduce the photovoltaic shading and increase the energy production.
Step 4: Select and place the PV modules and inverters from the extensive library
After you have modeled the site and analyzed the shading, you can proceed to select and place the PV modules and inverters for your photovoltaic system. Solarius PV provides you with an extensive library of PV modules and inverters from different manufacturers, with their technical specifications and performance data. You can also add your own custom models if you need to.
To select the PV modules and inverters, you can use the wizard that guides you through the process of choosing the best components for your system, based on your design criteria and constraints. You can also manually select the components from the library and drag and drop them on the 3D/BIM model.
Solarius PV will automatically calculate the number of PV modules and inverters needed for your system, as well as their optimal configuration and connection. You can also adjust the parameters of the components, such as the orientation, inclination, spacing, wiring, etc., according to your preferences.
Step 5: Activate, size and configure the storage system and the energy metering devices
If you want to increase the self-consumption and the energy independence of your photovoltaic system, you can add a storage system that allows you to store the excess energy produced by the PV modules and use it when needed. Solarius PV enables you to activate, size and configure the storage system for your project, by defining the battery type, capacity, efficiency, depth of discharge, etc.
You can also choose between different energy metering devices that measure the energy flows between your photovoltaic system, the grid and the loads. Solarius PV supports different types of meters, such as bidirectional meters, net meters, smart meters, etc., depending on your location and regulations.
Solarius PV will calculate the optimal size of the storage system and the energy metering devices for your project, based on your energy demand profile, load curve, tariff scheme, etc. You can also modify the parameters of the storage system and the energy metering devices according to your needs.
Step 6: Generate the wiring diagram of the photovoltaic system automatically
The final step is to generate the wiring diagram of the photovoltaic system, which shows how the components of the system are connected electrically. The wiring diagram is important for the installation and maintenance of the system, as well as for safety and compliance reasons.
Solarius PV allows you to generate the wiring diagram of the photovoltaic system automatically, based on the 3D/BIM model and the parameters of the components. The software will create a schematic diagram that includes the DC and AC disconnects, the grounding wire, the fuses, the wire sizes, the voltages, the currents, and the array size. You can also customize the wiring diagram by adding labels, symbols, notes, etc.
The wiring diagram can be exported as a PDF or DWG file, or printed directly from Solarius PV. You can also use the wiring diagram to perform a verification of the electrical system, by checking for any errors or inconsistencies in the design.
Step 7: Perform the financial analysis and the business plan of the photovoltaic system
The last step is to perform the financial analysis and the business plan of the photovoltaic system, which shows the economic feasibility and profitability of the project. The financial analysis and the business plan are important for decision making, financing, and monitoring of the project.
Solarius PV allows you to perform the financial analysis and the business plan of the photovoltaic system automatically, based on the technical design and the economic parameters of the project. The software will calculate the following indicators:
The initial investment cost, which includes the cost of the components, installation, permits, etc.
The annual operating and maintenance cost, which includes the cost of cleaning, repairing, replacing, insuring, etc.
The annual energy production, which is the amount of electricity generated by the photovoltaic system.
The annual energy consumption, which is the amount of electricity consumed by the loads.
The annual energy savings, which is the difference between the energy consumption and the energy production.
The annual energy bill, which is the amount of money paid or received for the electricity exchanged with the grid.
The annual cash flow, which is the difference between the annual income and the annual expenses.
The simple payback period, which is the time required to recover the initial investment cost.
The net present value (NPV), which is the present value of all future cash flows minus the initial investment cost.
The internal rate of return (IRR), which is the interest rate that makes the NPV equal to zero.
The levelized cost of energy (LCOE), which is the average cost per unit of energy produced by the photovoltaic system.
Solarius PV will generate a detailed report that includes graphs, tables, and charts that illustrate the financial analysis and the business plan of the photovoltaic system. You can also customize the report by adding your own logo, notes, comments, etc.
