Solar Relay -  With extended periods of bright sunshine and warm weather, even relatively large storage batteries in solar-power systems can become rather warm.  Consequently, a circuit is usually connected in parallel with the storage battery to either connect a high-power shunt (in order to dissipate the excess solar power in the form of heat) or switch on__ 

Solar Revolver -  A single-chip solarroller circuit with reverse and turning capability; based on a 1381 SE.   __ Designed by Wifl Rigter

Solar Robots -  Make your own solar powered robot at home using things you probably already have.  Transistors, resistor, capacitor, solar battery and flashing LED are available at any electronic store, if you don't already have them.  Solar cells out of calculators work as well, you might want to use more than one since they are really small__ 

Solar sensor draws less than 8 pA -  This Design idea was inspired by a requirement for a sunrise detector with low power consumption, reliable light detection, and a real sleep mode during darkness.  The sleep mode of the microcontroller with a __ Designed by David Tomanek

Solar Shed Lighting Testing -  Analysis of a typical solar shed LED lighting circuit.   __ Designed by REUK-Renewable Energy UK website

Solar Step Down Regulator -  This is an experimental circuit which rapidly "chops" a steady DC input voltage to produce a lower output voltage. Regulation is a function of the chopping - it is caused by the output transistor switching on and off around the target voltage, which when smoothed provides a constant DC output. __ Designed by Rowan from Melbourne, Australia

Solar switching regulator, Part 1 -  Circuit diagram - published in Silicon Chip Magazine January 1994 Part 1/2 __ Designed by  otakarpriboj @ otakarpribo j. com.au

Solar switching regulator, Part 2 -  Circuit diagram - published in Silicon Chip Magazine January 1994 Part 1/2 __ Designed by  otakarpriboj @ otakarpribo j. com.au

Solar tracker -  This kit monitors the position of the sun using two Light Dependant Resistors (LDR's) , and makes the decision to move the solar panel to correctly orientate to the sun.   The output configuration is called a H bridge which will drive a small electric gearbox up to 500mA at the input voltage (6 ..15V) , both forward and reverse.__ CdS Electronic

Solar Tracker -  I wanted to come up with a simple design that would be durable, cheap and easy to make.  if you have enough carpentry skills to make a bird house, you can build this tracker.   __ Designed by Rich Demartile

Solar Tracker Concept -  Make a very simple sun tracker to maximise electricity generation from a PV solar panel.   __ Designed by REUK-Renewable Energy UK website

Solar tracking control system -  Schematic only, no circuit description __ Contact Duane C. Johnson

Solar-Array Controller Needs No Multiplier to Maximize Power -  12/05/08 EDN Design Ideas:  Relying on the logarithmic behavior of transistor junctions to calculate power, this controller operates a photovoltaic array at its maximum power point __ Circuit Design by W Stephen Woodward, Chapel Hill, NC

SolarbotICs NV-Based -  uses a single IC (and it's a common one, too -the 74AC240) to give you motor drive in a single direction
 __ Designed by Wilf Rigter

Solar-Cell Converter Offers Positive Start-Up -  08/15/96 EDN Design Ideas:  Applications deriving power from solar cells often require a 5V power supply.  However, the cells typically provide a terminal voltage of only 0.8 to 1.4V with current capacity of 3 to 4A.  Most DC/DC converters can neither start with such low voltages, nor can they start under full-load conditions.  The two-IC  approach __ Circuit Design by Robert Badalian, Maxim Integrated Products, Sunnyvale, CA

Solar-Powered Home Lighting System -  This project suggests a system that uses solar power and LED lighting technology in a more efficient way.  Solar power systems use solar panels to convert the sunís energy directly to...__ Electronics Projects for You

Solar-Powered Intruder Alarm for Sheds & Boats -  Most blokes have got a shed - or wish they had!  While many people have alarms for their home and cars, a lot of valuable stuff is unprotected in garages and sheds.  it needs protecting and now you can do it with this simple alarm based on a PiR sensor.  it's solar-powered so no mains supply is needed.  And let's not forget boats on moorings - they need protecting too.__ SiliconChip

Solar-Powered Lighting System -  Need lighting away from a power source? Try this one: it's ideal for your garden, shed or even a camp site.  With a 5W solar panel, a 12V SLA battery and a smart controller, it has 3-stage charging for the battery and Maximum Power Point Tracking (MPPT) for the solar panel.__ SiliconChip

Solar-Powered Lighting System, Pt.2 -  Last month we described the operation of our new off-grid lighting system, featuring free power courtesy of the sun!  Now we move on to the fun part: building it! __ SiliconChip

Solar-powered Motor runs on 10 nA -  18-Mar-04 EDN Design Ideas:  Designs for solar-powered applications with low-duty-cycle requirements can often rely on capacitors for energy storage in place of less reliable batteries.  Typical applications include solar positioning, telemetry transmitters, chemical pumps, data loggers, and solar-powered toys.  The circuit in Figure 1 can run a small pager motor from the output of a small calculator-type solar cell in near __ Circuit Design by Stepan Novotill, Victoria, BC, Canada

Solar-Powered Pedestal Lighting System -  This solar-powered pedestal lighting system uses power LEDs for lighting.  Solar energy is first converted into DC electricity by a solar photovoltaic cell and used to charge a storage battery.__ Electronics Projects for You

Solar-Powered Pump Motor Controller -  A Discover Circuits visitor had a problem.  He needed a simple on/off controller for his solar powered water pump.  His system used two 12v 50 watt solar panels wired in series.  The power from the solar panels drove a submerged water pump.  However, during. . .

Switching Shunt-mode Solar/Wind Charge Controller -  This circuit is for a switching shunt-mode charge controller.  in a shunt-mode circuit, the solar panel is permanently connected to the battery via a series diode.  When the solar panel charges the battery up to the desired full voltage, the shunt circuit connects a resistive load across the battery to absorb the excess power from the solar panel __ Designed by G. Forrest Cook
