Four Types of Solar Water Heaters
From compact home systems to large industrial setups — LavishRays supplies, installs, and services all major types of solar water heaters.
Evacuated Tube Collector (ETC)
The most widely used system in India. Glass vacuum tubes eliminate heat loss and perform excellently even on overcast days. Ideal for homes and hostels.
Flat Plate Collector (FPC)
A durable option for regions with strong sunlight. Features a selective coating absorber and tempered glass cover. Longer lifespan for heavy usage.
Integrated Storage Collector (ISC)
A simple, compact system where the tank and collector are combined. Lower cost, easy installation, ideal for small households with 1-3 people.
Solar Heat Pump Hybrid
Combines solar thermal with a heat pump for 24/7 hot water. Excellent for hotels, hospitals, and apartments with consistent high demand.
How It Works &
What You Save
Solar Collectors Absorb Heat
Mounted on your rooftop, the solar thermal collectors absorb sunlight and convert it into heat energy at up to 75% efficiency — far more efficient than solar PV panels for heating purposes.
Circulation Through Collector
In ETC systems, water or a heat-transfer fluid circulates naturally through the vacuum tubes (thermosiphon) or via a pump, picking up heat from the collector.
Storage in Insulated Tank
Hot water is stored in a heavily insulated tank (typically 50–100mm polyurethane insulation) that retains heat for 24–36 hours — so your morning shower is always hot, even after a cloudy night.
Backup Heating Element
An electric backup element (typically 2 kW) activates only when solar energy is insufficient — on rainy days or during extended cloudy periods. This ensures 100% hot water availability year-round.
Integration With Existing Plumbing
The system integrates seamlessly with your existing hot water plumbing — showers, kitchen, bathrooms. No change needed to your fixtures. Standard installation takes 4–6 hours.
Estimates based on Hyderabad tariff ₹7.5/unit. Actual savings vary by usage and system type.

RIGHT-SIZED SYSTEMS
We size your system correctly for your actual usage — preventing oversizing (wasted money) and undersizing (inadequate hot water).
HARD WATER EXPERTISE
Hyderabad's water is notoriously hard. We specify the right anti-scaling protection for your area — extending system life.
POST-INSTALLATION SUPPORT
We're reachable after installation — not just during the sale. Our AMC plans ensure your system works perfectly for its lifetime.
4.9 GOOGLE RATING
Hundreds of satisfied customers across Hyderabad and AP rate us 4.9. Read our reviews before deciding — we encourage it.
Will it work in Hyderabad's climate?
Yes, very well. Hyderabad averages 300+ sunny days per year and strong solar irradiation year-round — ideal conditions for solar water heating. Even during monsoon, ETC systems work on diffuse light. The backup electric element handles the remaining cloudy days seamlessly, ensuring 100% hot water availability throughout the year.
How much roof space does it need?
A 100L system typically requires about 2 square metres of shadow-free rooftop space. A 200L system needs 4 square metres. For larger commercial systems, we calculate the exact footprint during our free site assessment. Most homes have more than adequate rooftop space — the system can be mounted at an angle to minimise space use.
What happens on rainy or cloudy days?
ETC systems still work on diffuse sunlight and heat water partially even on overcast days. All systems also include an electric backup heating element (typically 2 kW) that automatically activates when solar energy is insufficient — so you always have hot water. In Hyderabad, you'll use the backup element for perhaps 30–40 days per year during peak monsoon.
How long does installation take?
For a standard home system (100L–200L), installation typically takes 4–6 hours. Larger commercial systems may take 1–3 days depending on capacity and complexity. We schedule the installation at your convenience — typically within 3–5 working days of order confirmation. We clean up completely after the installation and test the system output temperature before we leave.
What maintenance does it need?
Solar water heaters are low-maintenance. The main annual tasks are cleaning the collector tubes (scale buildup in hard water areas like Hyderabad), checking the anode rod in the tank, and verifying plumbing connections. Our AMC plans start at ₹1,499/year and cover scheduled service visits plus priority support.
Is there a subsidy for solar water heaters?
Yes, the central government's MNRE provides subsidies for solar water heaters under the National Mission for Enhanced Energy Efficiency. Telangana and Andhra Pradesh also have state-level incentives periodically. The exact subsidy amount and availability changes based on current policy.
