1. A way of reducing carbon emission

2. Burning fossil fuel is one of the human activities that has a negative impact on the environment and it seems inevitable to avoid it since it is our main source of energy. However, The Sunforce 246- Watt High-Efficiency Polycrystalline Solar power kit uses an alternate technology that is environmental friendly and renewable. One of the biggest threat to human existence

3. What is fossil fuel Fossil fuel is formed by the decomposition of dead organic matter in the absence of air millions of years ago. Examples of fossil fuel include oil, gas, coal etc and they release energy and carbon when oxidised

4. World’s over-reliance of fossil fuel as a major source of energy About 87% of the total world’s energy demand is met by fossil fuel according to the Wikipedia Encyclopaedia

5. What does this mean Very large amount of carbon or carbon compounds is being released into the atmosphere every day. As a result, our environment is been polluted and one of the major consequence is global warming All the fossil fuels under the earth will be consumed with time. The need to get a more sustainable and renewable source of energy as an alternative is very essential.

6. The Sunforce Solar power kit The sunforce solar power kit converts light energy from the sun into electric energy and it’s operation is environmental friendly. It is made of two Sharp 123- Watt polycrystalline solar panels, a 200-Watt power inverter, a voltage tester, and a wiring kit, a 30-Amp Digital Solar Charge Controller, a 12V battery.

7. Solar panel One of the most important component of the Sunforce solar power kit is the solar panel. It is a photovoltaic cell which is made from polycrystalline silicon

8. How versatile is solar panel Solar panel technology can be used as a replacement for fossil fuel technology in many applications and this can help cap carbon emission to the atmosphere. It can be used at homes, in automobiles, in industries etc for power generation.

9. How a photovoltaic cell works A silicon PV cell is made up of a very thin layer of phosphorus-doped (N-type) silicon above a thicker layer of boron-doped (P-type) silicon. An electrical field is created at the P-N junction. When sunlight strikes the surface of a PV cell, this electrical field cause electrons to flow across the P-N junction resulting in a flow of current when the solar cell is connected to an electrical load

11. charge controller and inverter The charge controller regulates the amount of energy in flowing into the battery to protect the battery. The inverter converts direct current from the battery to alternating current.

12. Using the 150 motorcycle as a case study

13. The 150 Motorcycle The 150 Motorcycle is powered by an internal combustion engine. Inside the combustion engine, a mixture of benzene and air is burned under a very great pressure to produce the energy which is converted to mechanical energy.

14. Why is it necessary to replace the internal combustion engine The combustion produces carbon iv oxide which is ejected in to the atmosphere through the exhaust pipe. Therefore, we need to find a more clean source of energy.

15. How the solar panel could replace the #90 Benzene 4 stroke engine To make the motorcycle work with solar energy, The following components are needed. Two pairs of solar panel An electric motor Two converging lens Two light bulbs A battery A charge controller

16. Two solar panels could be placed on each side of the machine with one facing outside and the other facing a light bulb inside. A converging lens could be used to focus light energy from the sun and the bulb. The series combination of the four solar panel could drive an electric motor which could be connected to the wheels of the machine through a fly wheel.

17. The battery which is charged by the solar cell is used to power the light bulb. The charge controller protects the battery from overcharging. The battery is also connected to the motor for initial start up before the solar cells start to generate enough energy to power the electric motor.

18. Brand Image of solar panel Solar kit is perceived as a cheap sustainable source of energy in the community and some energy companies like British gas are offering free solar panels to customers to earn a good image in the market and attract more customers thereby increasing their sales revenues. According to Mark (2010), " more than 12 million homeowners would be in line to save up to £1,000 a year, should they install solar panels, says British Gas”.

19. According to FLRC News, First solar energy company reported a 14% increase in profit in the third quarter last year. The company's net income rose from $153.34 million to $176.87 million. The sale of this product is expected to grow in the future because the governments of different countries are now investing in it.

20. United state government has approved the world biggest solar energy project (Oct, 2010). More than 1000 megawatt of energy is expected to the generated. This is enough to supply energy to more than 300,000 single family homes and it will reduce Carbon emission by nearly one million short tons per year. This will also generate 7500 jobs.
