3. CHALLENGES
The solar chargers which were invented earlier are large in size and
weight. It is very difficult to carry anywhere because of “rugged” additional
features.
They don’t have the facility to store the charge. Hence we have to place our
costly devices in hot sun.
By connecting the device directly to a solar panel or in brown-out conditions,
variable voltage is supplied.
When the device receives more current, it will result in overheating and self-
destruction.
4. CHALLENGES(CONT….)
Many chargers are “Universal” but they discharge at the lowest rate for other
standard devices.
Some solar chargers are only suitable to either CTIA STANDARD or APPLE
standard.
They need some special USB cables.
The batteries are usually NimH or NiCd battery which is poor in storage and
have a high self discharge rate.
Lithium ion cells have no special charge control safety and will exceed safe
operating temperature and shut-down by the extreme heat.
5. CHALLENGES(CONT…)
The thin film cells used by solar
chargers are less expensive but have
lower energy conversion efficiency.
It absorbs the visible part of the solar
spectrum not IR part.
It can work in low-light conditions
but never work well in full sun
conditions.
7. PROPOSED SYSTEM
Solio private limited introduced the most advanced solar battery charger in
2010.
It is the combination of solar panel and smart battery.
This is a good companion for swimmers, treckers and whoever on the go.
It holds many special features to fulfill our needs while travelling.
9. FEATURES
Size is miniatured and fits into your palm.
Special output mode is built to charge all I- devices.
There are no extra cables or connectors or adaptors required.
It has two charging modes for CTIA standard and APPLE standard. A single
LED button to toggle between these modes.
Extra charge control protections for extreme heat conditions or brown-outs and
maintains the safe operating temperature.
10. BATTERY FEATURES
Battery is high temperature rated. So
it can tolerate high weather
conditions.
Excellent shelf life when stored at
40-85F.
Battery can be replaced easily.
11. BATTERY FEATURES(CONT..)
The battery is of type Li-Poly battery and it has uniform discharge rate to
protect the devices from damage.
It charges Iphone in just 60-90 minutes.
Solio has solar smart battery to deliver uniform power supply.
Battery has very low self-discharge rate and can store charge for 1 year of time.
Can retain up to 80% of its original capacity after 500 full charge and
discharge cycles. Hence it has more life span.
12. SOLAR PANELS
The highest quality wafer silicon
photo voltaic used by solio has
minimum 17.5% efficiency which
is the highest commercially
available limit.
Quality and efficiency of the solar
photo voltaics designed to suit for
small devices.
13. WORKS WITH I DEVICES
Ipad mini, ipad air, ipad 2, ipod,
Iphone 6
Iphone 6+
Iphone 5s
Iphone 5c
Iphone 5
Iphone 4
Iphone 4s
Iphone 3GS
Iphone 3G
14. WORKS WITH SMART PHONES
Samsung
ZTE
Huawei
Lenevo
LG
HTC
Nokia
and all types of kindles.
15. WORKS WITH SATELLITE PHONES
Iridium 9575
Inmarsat I sat phone
Thuraya SatSleeve
Thuraya XT
Delorme inReach Explorer
16. OTHER DEVICES
Solio can work even in other
devices like
GPS Watch
GoPro camera
Petzl RXP headlamp
Steri PEN ultra water purifier.

18. DISADVANTAGE
It cannot work for some models of satellite phones like SPOT Gen 3.
Solutions to overcome the limitations of thin-film silicon have been developed
but none or yet commercial leaving the efficiencies of thin film well below
those of wafer silicon cells.
It takes 8-10 hours to recharge by sun.
It cannot works in lowlight conditions.
19. CONCLUSION
Solar energy is the most eco-friendly form of energy which can be utilized in
order to perform our every day activities.
People all over the world have come conscious regarding the safety of the
environment.
The future driven by solar panels and batteries will turn the electronics and
electrical markets upside down.
