INTRODUCTION

Solar energy Solar panel cells Electric energy

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.

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.

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.

SOLIO BOLT

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.

USAGE

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.

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.

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.

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.

OTHER DEVICES

Solio can work even in other devices like

GPS Watch

GoPro camera

Petzl RXP headlamp

Steri PEN ultra water purifier.

SPECIFICATIONS Power: Max Wattage: 5 Watts Discharge Rate: Fixed 5V, 1,000mAh Charge Rate: 5-5.5V 450mAh Charge Time via USB port/wall charger: 4 hours 30 min. Charge Time via Sun: 8-10 hours Color: Pearl White Battery: 3.7V/2,000mAh Li-Poly - User replaceable at end of life (average 3

years) Weight/Dims: 3.5 x 3.5 x 1 in. - 5.3 oz. Cost: $70.0

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.

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.
