Always believing in new developments & changes for positive purpose, the sunray may have various characteristics like
Manufactured and fabricated from high grade of material under qualified engineers’ inspection at its own factory.
The Evacuated glass tube solar system is more efficient than flat plat solar collector because of its round shape, as the sunrays falls perpendicular any time, so the Evacuated glass tube solar system get the temperature faster than flat plat collector, and because of vacuum between the tubes, the heat loss during the cold night is very low than flat plat collector, so this system maintain the temperature overnight.
Key Technical Details for System Installation

 Calculation of Energy & Amount Saved On ETC
1 person = 1 bucket of hot water (Minimum) (about 20 liter) per day (600C)
1 bucket of hot water = 1 unit (minimum) of electricity = 1 KWh = Rs. 4.50
So, 5 persons = 5 unit per day = 5 x Rs.4.50/- = Rs. 22.5/- per day
Savings after 1 year = 345days x Rs.22.5/- = Rs.7760/- per year
