Sundrop Solar Hebbal, Bangalore, Karnataka

The FLAT PLATE collector absorbs the solar energy and converts it into heat energy. The cold water flowing through the riser pipes gets heated and moves into insulated storage tank through header pipe, due to low density of hot water it occupies the upper portion of the insulated storage tank and the cycle continues as long as the sun rays fall on the collector. By the end of the day the entire tank is with hot water. As the storage tank is insulated which retains heat overnight. In this principle water can reach temperature up to 600c – 850c.   Specifications:   COLLECTOR BOX Collector Size : 2030 x 1030 x 100 mm Collector Box : Extruded Aluminium, make – Indal / Jindal Grade – HE9T/HE9WP Finish : powder Coating Glass Retaining Angle : Extruded Aluminium as above Back Sheet : 22SWG, Aluminium, Revited and sealed with silicone sealed/ Galvanized sheet as per IS Glass : 4mm, toughened, low Iron content with 85% minimum transmitivity Glass/beeding/Sealing : EPDM with 35% rubber content along with the top Aluminium retainer angle, using SS self tapping Screws Grommets : EPDM with Inside / outside locking collar Ends Connections : 4mm thick brass flages with EPDM gaskets Insulations : 48kg/ cu.m density rockwool/ puff Bottom – 50mm and Sides – 25mm Reflective Foll : Aluminium – 100 microns for sides, 50 microns for bottom Frame Corners : Sealed from inside with Silicone Sealant and Provision of Corner Clips for better aesthetics and prevantion of moisture entry  ABSORBER Coating: Selective Bonding between Fins and Riser: Block Chrome – NALSUN Absorptivity > 0.95 Emmissivity : < 0.15 Ultrasonic Welding / Lead and Tin Soldering Bonding btw Header and Riser : Metallurgical bonding using 14% Silver Brazing rod Absorber Area : 2.07 sq.m Fins : 99.9% + -0.01 Copper – 120 mm wide, 36 SWG Number of Fins : 09 (Nine) Test Pressure : 5.0 kg/sq.cm Header : 99.9% + -0.01 Copper -1” x22 SWG Riser : 99.9% + -0.01 Copper-1/2 x22 SWG System Temperature : 60o C - 85oC  STORAGE TANK Inner Storage Tank : SS 304 Grade with TIG Welding Inter Connecting Pipes : SS 304 Grade End covers : Powder Coated pressed Aluminium dishes Insulation : 100 mm Rinsine bonded Rockwool Tank Outer Cladding : SS mirror finishing/ Powder Coated Aluminium with optional Colours   Features:   ISI marked 1.5 KW back-up heater with Thermostat(optional) All fasteners are made of SUS 304 Food grade for rust free.

Solar Street Lighting System is ideal lighting system for the illumination of streets & squares and cross roads    located in areas that are not connected to the power grid. The standalone solar photovoltaic street lighting system comprises of a solar PV module for battery charging, rechargeable lead acid battery for storage, Compact Fluorescent Lamp (CFL) as light source, suitable electronic control circuits for the operation of the lamp and safeguard to the battery charging and   discharging and hard-ware like pole, battery box etc. for fixing of these sub systems. Street Lighting System is designed for either with automatic dusk to dawn operation or with a pre-set timer. The street light luminary is designed for the operation in all weather conditions. The solar street light unique design is the result of ten years of experience in solar photovoltaic manufacturing and system integration.     Features:   Battery charging indicator. Low battery indicator. Dust and jet proof light unit. Temperature compensated set points.  

The Solar Lantern comprises of solar module, battery, electronics (PCB), LED lamp, covered with high transparent chimney and fitted in ABS housing. Sundrop Solar Lantern is a highly efficient portable light source, which gives an Omni directional bright light. The Solar Photo Voltaic (SPV) module provided with each lantern, it charges the Sealed maintenance Free (SMF) battery which is fitted inside the lantern when the SPV module exposed to sunlight. The battery will supply power to the  compact Fluorescent Lamp (CFL/LED) whenever required.   Features:   1. Safe and easy to operate2. Mobile phone Charger3. Absolutely pollution free4. Light weight easy to carry5. Excellent protections and indications6. Rugged and attractive body made of ABS plastic7. Poly carbonate / UV stabilized acrylic light diffuser8. Three mode variation in brightness for energy saving as per requirement   Specifications:  

Home lighting systems are ideal sources for providing indoor illumination in remote areas and un-electrified    villages. The solar home lighting systems essentially consists of the solar module, suitable module mounting structure, battery, battery box, charge-controller, luminaries, inter-connecting cables and switches etc. All light assemblies have built-in high efficiency and high frequency DC to Ac inverter circuits for suitable to run CFL lamps. The indoor lighting systems would also come with provision to power a 12V DC table fan or a black and white Portable TV as option.  The lighting system is designed to operate 3 to 4 hours a day. Homelight is a DC operated wall mountable indoor lighting luminary. It consists of a compact Fluorescent Lamp (CF Lamp) and a high frequency inverter. High frequency inverter offers high efficiency, more light output and long service life to the CF Lamp.  The indoor lighting luminaries are available in different lamp wattages and models. All adequate protections are provided in the luminary for safety, reliability and long life. These lights are ideally suited for lighting applications powered from renewable energy sources like solar, wind etc. these are widely used in Solar Home systems.
