Project Overview
This project features the design and installation of a commercial solar water heating system for a CPARM facility in Thailand. The system is built around the HP-1820 vacuum tube solar collector, engineered to deliver reliable hot water at 70ยฐC to support the operational needs of this specialized agricultural and food processing facility.
Regional Climate & Environmental Conditions โ Thailand
The project is located in Thailand, a Southeast Asian country renowned for its strong agricultural sector and favorable solar conditions. The local climate offers:
-
Abundant year-round sunshine with average daily solar irradiation of 4.5โ6.5 kWh/mยฒ
-
High ambient temperatures ranging from 25ยฐC to 35ยฐC throughout the year, reducing system heat loss
-
Distinct wet and dry seasons โ the dry season (NovemberโApril) delivers peak solar performance, while the wet season (MayโOctober) still provides substantial usable solar hours
-
High humidity levels (60โ90%), requiring durable, corrosion-resistant system components
-
Tropical storm exposure in certain regions, necessitating robust mounting and wind-resistant collector arrays
These conditions make Thailand an ideal location for commercial solar thermal installations, with strong solar resources supporting high system efficiency and attractive payback periods.

Technical Highlights
1. HP-1820 Vacuum Tube Solar Collector Technology
The HP-1820 evacuated tube solar collector is optimized for medium-to-high temperature commercial applications. Its vacuum insulation design minimizes thermal losses, enabling consistent 70ยฐC hot water output even during partially cloudy conditions common in Thailand’s tropical climate. This makes it well-suited for agricultural processing, sanitation, and industrial pre-heating applications.
2. Agricultural & Food Processing Application โ CPARM
This system serves a CPARM facility in Thailand, where reliable hot water is critical for operations such as:
-
Equipment cleaning and sanitation
-
Process water pre-heating
-
Crop drying and processing
-
Facility hygiene maintenance
The 70ยฐC outlet temperature meets the thermal requirements for these agricultural and food-grade applications, replacing or supplementing conventional gas or electric water heating.
3. Tropical Climate Engineering
All system components are selected and engineered for Thailand’s demanding tropical environment:
-
Corrosion-resistant frames and piping withstand high humidity and monsoon exposure
-
Wind-resistant mounting structure secures the collector array against tropical storms
-
High-temperature-resistant manifold design ensures longevity under continuous operation in hot ambient conditions
