1. How efficient is solar power in charging

cellphone batteries?

2. What are the possible reasons to

problems that can be encountered

when charging the phone using solarenergy?

3. What are the advantages and

disadvantages of using solar energy incharging cellphone batteries than

electricity at our homes?

Conclusion

The researchers proved that the use of solar energy incharging cellular phones is possible and at the same time

efficient. Though they have encountered problems the solar

panels still work.

Good quality solar panels are costly. If you did not buy

the best, you will not get the best result. Quality is more

important. It Is one of the reasons why the solar panel the

researchers use malfunction during the first trial. Solar panels

also need maintenance because they are sensitive to dirt, andscratches. Insufficient care for solar panels can reduce the

amount of energy that these panels can generate.

Moreover, using solar energy is much safer

than using the traditional electricity. It doesnt

harm our environment and at the same time it

will not put any persons life in trouble. Charging

using solar energy might be slower than chargingin electricity but imagine the safety it will bring

you.

ecommendationThe researchers recommend to the future

researchers who have plans of developing thisinvestigatory project to try different gadgets, or

even appliances, instead of cellphone batteries inorders to test the efficiency of the solar energy.Inventing alternative gadgets which will be

supported solar energy is also encouraged. These

invented gadgets which require the use ofelectricity. It is also recommended to the futureresearchers to choose the best quality of materials

to be used in order to have a more favorable result.
