Description

• Flat Plate Collectors (FPC): These systems utilize flat, insulated metal boxes with dark-colored absorber plates to collect solar energy. They are known for their durability and efficiency.
• Evacuated Tube Collectors (ETC): These systems consist of multiple transparent glass tubes containing heat-absorbing material. ETCs are generally more affordable but potentially less efficient and more fragile than FPC systems.

• Environmental Friendliness: Reduced reliance on fossil fuels and lower carbon footprint.
• Cost-Effectiveness: Significantly lower electricity bills as sunlight is a free and readily available energy source.
• Long-Term Reliability: Designed to last for many years (20-25 years), surpassing the lifespan of traditional water heaters.
• Reduced Maintenance: Fewer moving parts minimize the risk of mechanical failure and require minimal upkeep.
• Works on Cloudy Days: Well-insulated tanks can retain heat for 3-4 days.
• Power Outage Resilience: Provides hot water even during power cuts.

• Site Assessment: Choose a location with ample, unobstructed sunlight throughout the day.
• Collector Mounting: Install collectors on the roof or ground, optimally facing south for maximum sun exposure.
• Connecting Collectors & Tank: Use insulated pipes to connect collectors to the storage tank, ensuring tight seals.
• Storage Tank Placement: Locate the tank near the collectors to minimize heat loss and insulate it for optimal energy retention.
• Circulation System: Install a circulation pump connecting the collectors and storage tank, testing for proper water flow.
• Plumbing Integration: Connect the solar water heater system to the building’s existing hot water plumbing.
• Testing & Commissioning: Verify proper functioning, including leak checks, circulation, and hot water output.

• Government Subsidy: Check for available subsidies, as these can help offset the initial investment.
• Space Requirements: Typically requires 3-4 square meters of shadow-free area per 100 LPD system.
• Maintenance: Periodic inspections and cleaning are recommended, especially in areas with hard water.
