May 20, 2026

Project Overview

Client: Sennics
Location: Thailand
Application: Industrial Solar Hot Water Boiler System
Product Solution: CPC1518 Solar Collectors + Heat Pumps
Project Scale: 720 m² collector area

Project Background

Sennics, a leading industrial enterprise in Thailand, required a reliable and cost-effective solution to meet its high-temperature hot water demand for production and facility operations. With rising energy costs and a strong commitment to sustainable manufacturing, the client sought a renewable energy system capable of delivering 90°C process hot water without relying on government subsidies or incentives.

CPC Solar Heat Pump Hot Water System for Sennics Thailand 2

Our Solution

We engineered and installed a solar hot water boiler system that combines high-performance CPC solar thermal technology with advanced heat pump integration to maximize efficiency and output.

1. High-Performance Solar Thermal Array

CPC1518 solar collectors covering 720 m² of rooftop area
Advanced CPC (Compound Parabolic Concentrator) technology optimized for high-temperature heat generation
Designed to capture maximum solar radiation throughout the year in Thailand’s tropical climate

2. Heat Pump Integration

Industrial-grade heat pump units deployed to supplement and boost thermal energy output
The hybrid CPC + heat pump configuration ensures consistent 90°C hot water delivery even during periods of fluctuating solar availability
Seamless integration between solar thermal and heat pump systems for optimized energy cascading

3. Storage & Distribution

Large-capacity insulated hot water storage tank for buffering and load management
Engineered piping and control architecture to support continuous industrial hot water demand

Project Results

Key Metrics	Performance
Annual solar thermal yield	399 MWh
Hot water output temperature	90°C
Investment payback period	6.5 years
Subsidies / incentives	None required

The system delivers nearly 400 MWh of clean thermal energy annually, significantly reducing the facility’s reliance on conventional fossil-fuel-based boilers and cutting overall energy operating costs.

Value Delivered
