2. HOW TO STORE THE ENERGY Through the use of a technique used in thermal plants Water is in one thermotank while molten salt (from NaNO 3 and KNO 3 ) in another In a heat exchanger, Current is passed through the water which heats it to its boiling temperature to produce steam which heats up the molten salt After that the hot salt is stored away. In times of darkness, the hot salt is passed through the heat exchanger, to heat up the water which produces steam to turn a turbine connected to a generator, which creates electricity.

3. Subsequently the generator can be connected to a grid

4. HOW TO MAKE SOLAR PANELS LESS EXPENSIVE Solar panels are made very thin thereby making them expensive If it can be made thinner or one side and thicker on the other, it will make it less expensive Through the use of cylinder rods It absorbs light through the length and releases electrons on the width.

5. DESIGN OF THE SOLAR PANEL

8. NOTES TO TAKE The terrestrial radiation on Nigeria’s land area is 2.079 x 10^15 kWh/year and average annual consumption of all forms of energy in Nigeria is 2.4026 x 10^11kWh and the electrical energy consumption in the year 2001 was 15 x 10^6 kWh Current technologies cost between N240-N360 per watt N10 – N15 per Kilowatt/hour Advancement in solar technologies will allow N4 - N6 per kWh in the next few years

9. Most solar cells cost less than N480 per watt output and is guaranteed for over 20 years. Absorption is approximately 939W/m^2. A solar panel with 1000m^2 surface area and with 10% power conversion efficiency would generate 94kW Hence, total photovoltaic panel will cost = 480 x 94000 = N45,120,000 National power presently cost N21 per kWh.

10. 2007 average cost of wind N65.60 Installed wind power capacity cost N144,000- N999,000 per Kw References Abdulkarim, H.T. Techno-Economic Analysis of Solar Energy for Electric Power. Minna, 2004.
