Overview

The Italy-based customer SolarSavvy tasked us with a challenging project of developing a robust platform from the ground up. The ubiquitous goal was to facilitate solar panels monitoring, including their condition, the amount of energy produced, location management, and more.

During our collaboration, we conducted in-depth research into this industry and dived deeper into users’ expectations and problems to be covered, which allowed us to develop and design an in-demand solution.

Deliverables

Results

Based on our findings and customer needs evaluation, our experts created web and mobile applications that promoted optimized processes of solar panel management, from consumption to performance, helping users avoid possible maintenance problems and save money in the long run. This solution is aimed at streamlining monitoring for commercial users and enterprises.

The platform is aimed at increasing user engagement and lead generation, so after we launched the solution, it reached a 30% improved lead-to-client conversion rate due to better UI/UX and strong back-end structure that reduced downtimes and performance issues. Moreover, we implemented some real-time features that reduce response waiting for customers by 45%.

Information Architecture

To ensure the solution is easy to navigate so that everyone can find their way across tabs, we considered our research on user preferences and behavior. As a result, we placed core settings and tabs on the left side, dividing them into categories of “Menu” and “Support,” allowing smooth interactions.

Modular architecture has become a perfect option for independent and strong web and mobile platforms with the usage of NestJS and GraphQL. Our experienced specialists used all the strengths of the modular type, from easy integrations to flexibility and easier scaling.

Information Architecture

Technologies We Used

The tech stack is critical for web and mobile platforms, so our team decided to move with robust technologies to ensure efficiency and high performance, maintainability, and smooth operations:

Front-end

React.js

Next.js

Back-end & API

NestJS

GraphQL

Data & Realtime

PostgreSQL

Redis

WebSockets

Infrastructure

AWS

Docker

Integrations

Firebase Auth

Stripe API

OpenAI API

Security

The solar platform handles sensitive information, which becomes a target for cyberattacks, so we wanted to prevent data breaches and unauthorized access by implementing the following practices:

Firebase Authentication used for secure sign-in and session handling.

JWT-based access control on backend with role-based permissions.

Stripe API implemented securely for subscription and payment workflows.

WebSocket communication channels are encrypted and token-authenticated.

AWS CloudWatch enables continuous monitoring and security alerting.

Discuss your idea with our experts to define the perfect solution for your needs.

Functionality

To develop reliable features, we decided to go with the needs and requirements from end-users who needed an ability to manage the panels, administrate their performance, make changes in real-time mode, and more.

Dashboard overview

On this page, we have placed crucial monitoring features and visualizations: solar panel monitoring with total charging, power usage, status, capacity, and others, as well as all the available constructions across different locations, weather forecasts, energy production graphs, and more.

Panel inspection

We have researched that the ability to manage locations using cameras is vital for owners, so we created a “Locations” informational block where users can check efficiency, daily output, operating voltage, and other parameters.

Performance control

For more visualization, we have developed and designed tools that enable the monitoring of energy production in different locations, general performance divided into monthly, weekly, and daily metrics, and even the top 10 energy losses with a simple and effective graph.
