Solar panel
3. 𝗈 The sun is a star made up of hydrogen and helium gas and it
radiates an enormous amount of energy every second.
𝗈 Solar cell works on the principle of photovoltaic effect. Sunlight
is composed of photons, or "packets" of energy.
𝗈 These photons contain various amounts of energy corresponding
to the different wavelengths of light.
𝗈 When a photon is absorbed, the energy of the photon is
transferred to an electron in an atom of the cell.

6. 𝗈 Uses high-efficiency mono crystalline silicon.
𝗈 Solar panel: 5.5V/1000mA
𝗈 Output voltage: 5.5V
𝗈 Output current: 300-550 mA
𝗈 Time taken to charge mobile phone using the
charger : about 60mintues for typical mobile.

11. 𝗈 Relatively small size allows mobile use.
𝗈 System required electrical start-up power.
𝗈 Solar concentrator can be used with any heat
source.
𝗈 Higher efficiency then photovoltaic system of the
same scale.
𝗈 Ability to recharge AA batteries any time & any
where there is sun light.
𝗈 Low maintenance , emission-free &
environmentally-friendly power source.

12. 𝗈 Uses low input voltage to produce high voltage
spikes of output for charging.
𝗈 Utilize renewable sources.
𝗈 Bring convenience to the users.
𝗈 Useful for users in remote area & Portable for
travelers.
𝗈 To save the electricity bill cost in the long run.
𝗈 Reduce environmental pollution.
12
13. 𝗈 Cost is high.
𝗈 It is also applies the portable device.
𝗈 Charger is different type such as-Laptop , cell
phone & MP3 player.
𝗈 Solar charger have no capacity to store the
energy.
𝗈 They are only for use small amount of time.
𝗈 It will not work in cloudy day.
𝗈 It may not be ideal in your situation. 13
14. 𝗈 In solar mobile charger ripples will not be there as we use DC
power directly to charge the mobile.
𝗈 Battery life is more as high voltages are not developed.
𝗈 Versatility of Solar mobile charger is high.
𝗈 Life of the battery will be high as we use solar mobile charger.
𝗈 Adaptability is high. 14
