About Roofsol Energy

Roofsol Energy Pvt. Ltd. operates in the solar energy sector, developing and managing solar projects across India. The company has invested in multiple solar projects under the OPEX (CAPEX-free / RESCO) business model, where continuous monitoring of generation, plant performance, equipment health, and operational efficiency is essential.

As part of its technology development strategy, Roofsol Energy intends to establish its own end-to-end solar monitoring ecosystem, including proprietary data loggers, IoT-based data acquisition systems, cloud infrastructure, and a centralized solar generation monitoring platform. The objective is to develop and own the underlying technology and Intellectual Property (IP), while ensuring reliable monitoring and management of a large portfolio of distributed solar projects across India.

Role Overview

Roofsol Energy is looking for an experienced technology professional to lead the conceptualization, design, development, deployment, and maintenance of an in-house solar data logging and generation monitoring system.

Key Responsibilities

1. Product Strategy and Technology Development

· Define the technology roadmap for Roofsol Energy’s proprietary solar monitoring and data acquisition ecosystem.

· Lead the end-to-end development of the monitoring platform, from product architecture and prototype development to commercial deployment.

· Evaluate appropriate hardware, communication protocols, software frameworks, cloud technologies, and system architectures.

· Develop solutions suitable for both small rooftop solar installations and large distributed solar portfolios.

2. Data Logger and IoT Hardware Development

· Lead the design, development, prototyping, testing, and deployment of in-house solar data logging equipment.

· Develop expertise in integrating inverters, energy meters, weather sensors,



and other plant equipment using protocols such as Modbus RTU/TCP, RS485, Ethernet, and MQTT, as applicable.

· Ensure reliable data acquisition, local buffering, time synchronization, remote configuration, and recovery during network or power outages.

· Establish hardware validation, field testing, quality assurance, and lifecycle management processes.

3. Cloud Platform and Software Development

· Lead the architecture and development of a centralized cloud-based solar monitoring platform.

· Establish scalable infrastructure for collecting, processing, storing, and analyzing data from hundreds of geographically distributed solar installations.

· Oversee the development of dashboards, plant-level monitoring screens, portfolio-level reporting, alerts, notifications, and automated performance reports.

· Ensure integration with existing business systems, maintenance workflows, and third-party equipment where required.

· Establish high availability, disaster recovery, backup, cybersecurity, and system performance standards.

4. Solar Generation Monitoring and Analytics

· Develop real-time and historical solar generation monitoring capabilities.

· Establish monitoring of energy generation, plant availability, equipment health, communication failures, and performance deviations.

· Enable automated alerts for generation losses, inverter faults, abnormal operating conditions, and data gaps.

· Support performance analysis through relevant metrics such as specific yield, Performance Ratio (PR), plant availability, and actual-versus-expected generation, where applicable.

5. Intellectual Property and Technology Ownership

· Build and maintain Roofsol Energy’s proprietary technology stack,



including hardware designs, firmware, software source code, system architecture, technical documentation, and associated IP.

· Establish appropriate IP ownership, confidentiality, source-code control, licensing, and third-party technology compliance practices.

6. Team Leadership and Vendor Management

· Build and lead a multidisciplinary team covering embedded systems, electronics, firmware, IoT, cloud engineering, software development, and data analytics.

· Evaluate and manage technology vendors, hardware manufacturers, system integrators, and development partners.

Candidate Profile

· Bachelor’s or Master’s degree in Electronics & Telecommunications, Electrical Engineering, Instrumentation, Computer Science, Embedded Systems, IoT, or a related technical discipline.

· Approximately 10 years of relevant experience in IoT product development, embedded systems, industrial data acquisition, cloud platforms, energy monitoring, or related technology domains.

· Demonstrated experience in developing and deploying connected hardware and software products, preferably from concept through production and field deployment.

· Experience with cloud infrastructure, databases, APIs, cybersecurity, remote device management, and scalable system architecture.

· Knowledge of solar PV systems, inverter communications, energy meters, generation monitoring, and renewable energy analytics will be highly advantageous.
