This portable solar lantern circuit uses 6 volt/5 watt solar panels are
now widely available. With the help of such a photo-voltaic panel we can
construct an economical, simple but efficient and truly portable solar
lantern unit. Next important component required is a high power (1watt)
white LED module.
When solar panel is well exposed to sunlight, about 9 volt dc available

We propose to build a solar battery charger that will charge a variety of batteries: NiMH, NiCd, Li-ion, lead acid. Although there are solar battery chargers on the market, most are only for one application: cell phone, NiMH batteries, etc. Our charger will have the user input the battery type, capacity, and voltage. It will display the charge status and incorporate various safety World Financehttp://www.blogger.com/profile/01757977038242858610noreply@blogger.com1tag:blogger.com,1999:blog-6240469629267407912.post-30588909886512315192012-02-29T14:54:00.002+02:002012-09-09T01:19:34.420+02:00Solar charger controller circuit diagram
When connecting a solar panel to a rechargeable battery, it is usually necessary to use a charge controller circuit to prevent the battery from overcharging. Charge control can be performed with a number of different circuit types. Lower power solar systems can use a series analog charge controller. Series regulators control the charging current by interrupting the flow of current from the World Financehttp://www.blogger.com/profile/01757977038242858610noreply@blogger.com3tag:blogger.com,1999:blog-6240469629267407912.post-52674438307441043232012-02-29T14:05:00.002+02:002018-01-09T18:00:33.023+02:00Solar charger circuit diagram
A simple solar charger circuit can be constructed using this circuit diagram .
The nominal voltage of the solar charger circuit module is determined by the number of battery cells to be charged. Because of the typical voltage drop of 0.3 to 0.4 V across Schottky diode D1, the nominal voltage should exceed the charge voltage set on P1 by about 0.3–0.4 V .

As renewable energy is becoming integrated into our everyday lives, new terms such as solar panel, photovoltaic and solar cell are more common and new devices, such as outdoor LED lighting are using this technology. The sun emits many forms of radiation. The best way to describe this is that there are ‘waves’ of energy that radiate from the sun at different frequencies.
