Birds Eye Energy | FAQ
Basic Information
Birds Eye Energy procures certified PV panels from Premier solar, Hyderabad. These panels are then assembled into Birds Eye Energy's duplex panels in our assembly facility in Hyderabad. We are 100% made in India, 100% designed and developed in India and 100% made for India!
Birds Eye Energy also provides installation services for our duplex panels. Also, Birds Eye Energy's duplex modules are easy to install and can be installed by any certified solar EPC company. The design of the electric system including the string design, output calculation etc is exactly the same as a regular PV module and the plumbing system design, solar tank installation, piping design is exactly similar to that of solar hot water collectors. This enables certified solar EPC companies to procure our panels and install them with minimal guidance from Birds Eye Energy.
No. No special components such as wires, inverters, plumbing, pipes etc are needed for installation of Birds Eye Energy's duplex panels. This enables easy installation of the modules with components that can be cost effectively sourced from local suppliers.
Birds Eye Energy's duplex panels can be installed as grid connected or with battery back up only, or under hybrid configuration (both batteries and grid connectivity); just like regular PV modules.
The unused hot water is still stored in the insulated hot water tank to be used the following day. This tank can store the hot water with out loosing temperature for 48 to 72 hours.
For a typical house hold with a 3KW or a 5KW system installed in grid connected configuration, regular household equipment such as refrigerator air conditioner etc can be run. For systems which are installed as battery back up only or as hybrid configuration house hold equipment such as refrigerator, air conditioners etc can be run if the batteries have enough energy to support the operation.
Yes! An already existing PV panel installation can be converted into a duplex system. Birds Eye energy can retro fit such a system as per customer requirements. Please contact us through the inquiry form for more information regarding such a system.
Yes! Any amount of energy that is generated using solar energy is savings! Energy produced using Birds Eye Energy's duplex modules is significantly cheaper than the cost of energy from electricity grid. Hence installing a system which can cater to a part of total energy consumption is also a good investment and provides pay back with in 4 years and continues to save money for customer upto its design life of 20 years.
Birds Eye Energy's duplex panels can be installed on standard PV mounting structures. Since the weight of our duplex panels are only marginally heavier than standard PV panels.
Yes! Birds Eye Energy can replace the solar hot water panels and install Birds Eye Energy's duplex panels. Our duplex panels are designed to interface with the existing plumbing system, hot water tank, pumping system (if installed) or the prior installed solar hot water panels; hence these components need not be replaced if they are in good condition.
Technology
Typical solar panels have very low efficiency of about 15 to 20%. This means that 80 to 85% of the solar energy falling on the panel is wasted as heat. Birds Eye Energy duplex panel have a unique patented heat recovery system that capture the waste heat coming from the PV panels. This captured heat is used to heat the water. Thus, our unique duplex panels generate the same amount of electric power as a conventional PV panel and additionally provide hot water; both out of a single panel which is the same size as a conventional PV panel.
Birds Eye Energy's duplex panels generate 330W of peak electric power (like a conventional solar PV panel) and in addition also generate 75 litres of hot water per day; both out of a single panel which is the same size as a conventional PV panel.
No, the electric output of Birds Eye Energy's duplex panels is the same as a conventional PV panel (330W). The duplex panels contain two layers; the electric layer and a heat recovery layer. Though these layers are in physical contact, they operate independent of each other, the generation of hot water does not affect the electricity generation.
Birds Eye Energy panels are designed to have a life span of 20 years.
Birds Eye Energy's duplex panels are developed by Birds Eye Energy's research team headed by the founder Praneeth Pillarisetti in collaboration with eminent scientists at IIT-Madras, CSIR-CEERI Chennai.
Yes, Birds Eye Energy's duplex panel technology is patent protected. This means that the customers who invest in this innovative technology are ensured of the best quality and long life of the products.
Yes, the panels are designed to work with pressurized water systems. The panels are designed to with stand 10 bar (150 psi) water pressure.
Scaling is one of the most common problems for most hot water systems. Birds Eye Energy's unique heat recovery jacket is designed with water passages that reduce the scaling by 50% as compared to conventional hot water systems.
This helps to reduce the maintenance cost and to reduce the frequency of 'acid wash cycles' of the panels.
In addition to reducing the amount of scaling, Birds Eye Energy's duplex panels also have 2X thicker walls compared to regular flat plate collectors. This ensures that the panels can with stand any number washing cycles that need to be done over their life period of 20 years.
No. Birds Eye Energy's duplex panels need less maintenance compared to regular solar hot water panels.
The most cumbersome maintance activity for solar hot water panels is the acid wash cleaning to remove the scaling. Since Birds Eye Energy's duplex panels are designed with unique water passages that reduce the scaling by 50%. This cuts down the cost and frequency of maintenance activity needed for the modules.
Birds Eye Energy's duplex panel uses only all copper for the water jacket. Hence there is no risk of leakages due to corrosion or rusting.
Definitely not! Birds Eye Energy's duplex panels are designed to have a stagnation temperature of 80degC. During times when the hot water is not being used, even for extended periods of multiple weeks, the temperature of the module does not increase above 80degC. Hence there is no risk of over heating, steam formation or damage to plumbing system.
Safety related
Birds Eye Energy panels are rated to operate at 10 bar (150 psi) pressure. 100% of the panels are inspected to with stand 20 bar (300 psi) pressure. The heat recovery layer that carries water has been tested under accelerated ageing tests to ensure that the modules do not develop leakages over the life time of the product.
In addition to the above safeguard tests, Birds Eye Energy's duplex panels are designed not to get short circuited even when fully immersed in water. For this 'Wet current leakage test' the panel is completely immersed in a tank of liquid and panel still does not conduct any current or voltage to the water.
Birds Eye Energy's duplex modules are made from certified PV panels procured from Premier Solar, Hyderabad. The PV panels procured have IEC 61215 and IEC61730 certifications. Our PV panels used to manufacture Birds Eye Energy duple only class A mono crystalline cells that ensure minimum degradation and long life. All our panels are subject to Premier Solar's stringent incoming and out going quality certification.
Customer benefit
Birds Eye Energy's duplex panels are even better suited for customers who have limited roof top area. Birds Eye Energy's duplex panels allow the customer to generate maximum energy per sqft, thus allowing the customer to maximize the savings from his limited roof top area. For example; for a traditional PV system, 1KW installation takes up 100sq ft of roof top space and for a traditional solar hot water system a system with capacity of 200 litres per day takes up about 100sqft of roof top area. For a customer who needs both, stand alone electric and hot water systems would occupy a total of 200 sqft of roof top area. However, a solar energy system with Birds Eye Energy's duplex panels can generate both 1KW of electricity and 225 litres of hot water per day with in the 100sq for of roof top space. This allows you to maximize the total energy output for a limited roof top space.
Yes!. Birds Eye Energy's duplex panels are designed to operate in tandem with standard PV panels. The performance parameters of the module such as peak power, voltage at peak power, current at peak power etc are designed so as to enable operation of Birds Eye Energy modules in tandem with standard 72 cell PV modules.
For example: Every 1KW of Birds Eye Energy duplex panels system (built with 3 duplex panels) generates 225 Litres of hot water per day. If a customer needs 5KW of electric output and only 225 litres of hot water, the system can be built with 4KW of standard PV panels and 1KW of Birds Eye Energy's duplex panels. Such a system would have total of 5KW electric output and 225 litres of hot water output per day.
