Solar Thermal

At home we need Hot water for bathing and washing.
Industries require hot water for various processes including space heating and climate control.

Solar Hot water systems are the best choice for domestic as well as industrial use.  They are more efficient when compared with Solar PV in converting the suns energy into useable energy.

 A typical Domestic hot water system consists of a Solar Thermal Panel (1, 2, 3 or even 4 panels are used for a single system).  The other important component is the Solar Tank.  This is where hot water is stored.  It is thermally insulated and is the equivalent of a Battery in a PV system.

 Although there are two basic types of Panels - Evacuated tube type & Flat Plate type - the Flat Plate Collector is more commonly used.

 Each Panel is approximately 2 square Metres.
It generates the equivalent of 5 KWh of electricity on a typical Sunny day in most parts of India.  (The generation will vary by geography & season).
If we compare this with a 2 square metres of Solar PV panel; a PV panel generates about 1 KWh of electricity.

Annunciator

Design & Development of Annunciator . For a California based Company redesigned their annunciators around modern technology. The annunciators could handle 1 to 128 input modules with inputs to display from 8 to 1024 zones. The original full analog design was simplified with a single main PCB with a powerful microcontroller and multiple smaller PCBs with smaller microcontrollers, Analog & Digital inputs and outputs. PC based Software was developed to configure the system for multiple parameters. The duration of the project was 8 months.Test jigs were replicated at both places (USA & Goa, India).

18650 Li-Ion Cell - The Iconic Battery!

18650 - This is the most common standard for a Li-Ion battery (or Cell in correct technical terms).  In your Laptop, usually multiple 18650 cells are connected in series to provide a higher voltage.  A 2-cell battery (Multiple cells connected together is technically called a battery), will have 2 cells in series and produce 7.2 to 7.4 Volts. The Power Bank that we talked about in my earlier post usually comprises or 1 or more 18650 cells - But these are connected in parallel. There are wild claims regarding the capacity of power banks and 18650 cells as well. So lets make it clear here - The Size of a 18650 cell is 18x65mm.  In that space there is little room for wild swings in capacity - The Chemistry is nearly the same.  So we have real capacities ranging from 2,000mAH to 3,100mAH. Cell capacities are Colour coded (You can check the details in one of the links below).  The Purple Colour Cell manufactured by Samsung is one very commonly available battery...
