1. PHOTOVOLTAIC INSTALLATIONS
Creates residential, industrial and collective photovoltaic projects.
STEP 1
Easily generates the consumption curve
Creates the consumption profile from predefined profiles, import the exact consumption curve or define it manually, then adjust the tariff and consumption parameters precisely, and let Wattwin do the necessary energy and economic calculations for you.


STEP 2
Design the photovoltaic system visually on the map
Whether you are an engineer, technician or salesperson, designing installations is really easy and intuitive in Wattwin. Directly on the roof, start drawing the area to be covered, configure the usual installation parameters and the intelligent design wizard will take care of the rest for you.
STEP 3
Optimize your photovoltaic system with precision
Configure the ideal project for your customer by adjusting and optimizing the installation thanks to advanced design tools.
- Intelligent photovoltaic recommender
- Purpose selector: self-consumption, compensation, grid sale, zero injection, virtual battery, PPA agreement, among others.
- Obstacle designer
- Shadow Calculation
- 3D Viewer
- Inverter validator
- Batteries and storage


STEP 4
Configure a collective self-consumption installation
Make your collective photovoltaic installation projects a reality thanks to Wattwin's unique solution.
- Installation for residential buildings
- Installation for industrial buildings
- Installation for energy communities
STEP 5
Know energy production and economic projection in seconds
Knowing every detail of your installation is vital to optimize its performance to the maximum, that is why Wattwinautomates the calculation of:
- Energy balance
- Energy production graphs
- Economic projection
- Invoice comparison
- Sensitivity analysis

STEP 6
Generates the quotation and commercial offer automatically
While you focus on designing and configuring the installation, Wattwin can automate the generation of the budget and the necessary items (BOM), as well as the commercial offer. From here, the sales process follows thanks to the integrated commercial tools.
2. Aerothermal installations
Creates aerothermal projects

STEP 1
Enter the data of the house
The aerothermal designer allows you to create fully customized and complete installations in an agile way. The first step is to indicate the characteristics of the house, building or space where the installation will be carried out.
STEP 2
Design your aerothermal installation easily
Configure the details of your complete installation with all the necessary details to adjust the installation to your customers' needs in just 3 steps:
- Enter the current fuel
- Select the aerothermal system
- Select the emitters


STEP 3
Optimize the aerothermal installation in one click
Make sure that your installation is the most suitable for your customer thanks to the aerothermal system recommender algorithm. A powerful technical tool that recommends the most optimal aerothermal system for each project.
STEP 4
Obtain energy and economic projection automatically
Without the need to do it manually, you will get the report and the calculations you need about the installation:
- Installation summary
- Energy balance
- Cost Comparator
- Product breakdown

STEP 5
Generates the quotation and commercial offer automatically
While you focus on designing and configuring the installation, Wattwin can automate the generation of the budget and the necessary items (BOM), as well as the commercial offer. From here, the sales process follows thanks to the integrated commercial tools.
3. OTHER PROJECTS
