A Complete Overviewof the Project
A renewable energy service provider was responsible for managing and calculating solar power generation data for approximately 50 industrial clients. We designed and developed a customized ERP and solar calculation automation platform to centralize the entire operation, automate complex calculations, reduce human dependency, and provide a scalable foundation for future growth.

From IdeaTo Experience
Custom ERP automating solar generation calculations, validation, reporting, and client-wise energy records.
A renewable energy service provider was responsible for managing and calculating solar power generation data for approximately 50 industrial clients.
Each industrial client could have multiple solar feeders/meters, often ranging from 5–10 or more, and the calculated generation data needed to be prepared according to the requirements of different electricity providers such as DGVCL, MGVCL, Torrent Power, and others.
The process involved large amounts of meter data, highly precise calculations, multiple reporting formats, historical record management, validations, and monthly submissions.

Challenge
Automated Unit Calculation Engine
Eliminated 50+ manual Excel steps by automating complex solar generation calculations across multiple electricity providers.
Approach
Multi-Feeder & Client Tracking
Centralized solar meter management across 50+ industrial clients with 5–10+ meters each in one unified platform.
Solution
Automated Multi-Format Reporting
Instant generation of provider-specific monthly calculation sheets, validations, and historical energy generation records.
TheProblem
The client had already developed a sophisticated Excel-based calculation system containing formulas and business logic for processing solar meter data.
However, as the business expanded, Excel became increasingly difficult to manage.
The major issue was not simply performing a calculation.
The real challenge was managing:
- Approximately 50 industrial clients
- Multiple meters/feeders under every client
- Different electricity providers
- Different calculation methodologies
- Different reporting formats
- Monthly and historical records
- Large volumes of meter data
- Extremely precision-sensitive calculations
The process created significant operational dependency on manual tracking and Excel files.
WhatWe Built
We designed and developed a customized MERN-stack ERP platform specifically for solar generation calculation and reporting operations.
Instead of simply recreating Excel on the web, we converted the client's complete workflow into structured software modules.
01
Centralized Client Management
A structured client management system was developed where each industrial client could have its own:
- Company information
- Electricity provider
- Meter details
- Solar feeder details
02
Automated Calculation Engine
One of the largest parts of the project involved converting the client's existing Excel-based formulas and business logic into a software-driven calculation engine.
03
Provider-Specific Calculation Logic
Instead of maintaining separate Excel templates manually, different provider-related calculation workflows were incorporated into the software.
04
Automated Meter File Processing
The platform was designed to process different types of incoming meter files.
05
Precision-Sensitive Calculation Architecture
Because the system deals with extremely small decimal values, calculation accuracy was treated as a core architectural requirement rather than a normal arithmetic operation.
- Data was processed consistently
- Calculations followed defined rules
- Aggregations remained accurate
- Validation was performed before reporting
06
Automated Reporting
The client previously created multiple report formats manually after completing the calculations.
07
Historical Data & Analysis
The ERP was designed not only for calculation but also for long-term operational visibility.
- Weekly
- Monthly
- Quarterly
- Yearly
08
Centralized Record Management
Instead of maintaining scattered Excel files across a local computer, the software provides structured storage and retrieval of:
- Client records
- Meter information
- Uploaded files
- Calculated data
09
Automated Email Functionality
An automated email workflow was also incorporated into the platform.
10
Anywhere, Multi-Device Accessibility
The original Excel-based process was primarily dependent on the client's local computer and locally managed files.
- Desktop
- Laptop
- Tablet
- Mobile devices
11
Scalable Data Architecture
Because the client's business was expected to continue growing, the backend and database structure were designed with future expansion in mind.
- Industry clients
- Solar meters
- Solar feeders
- Monthly meter readings

ClientFeedback
Before working with us, the client had explored solutions with other development teams but was unable to achieve the exact combination of calculation accuracy, workflow understanding, automation, and flexibility required for their business.
“Turn the Excel workflow into automated software.”
Renewable EnergyThe actual requirement was to understand the business logic behind the spreadsheet and convert the client's complete operational process into a reliable software platform.
