About 22 athletes will be representing Nigeria. Nigeria will be participating in 4 events namely; Para Powerlifting, Para-Athletics, Para Rowing and Para-Table Tennis.
I’m sure you are reading this because you plan to set up a solar system for generating electricity. Or you need basic information on solar system setup. You are in the right place.
Let’s go straight to the point.
Items you need to set up a solar system for electricity generation
1 Solar panel
solar panels
Simply put, solar panels convert energy from the sun into electrical energy. Solar panels are durable. A good one can last 10 years. Cost of solar panels varies depending on size. As of writing this article, the cost of a 100w solar panel is around 20 thousand naira.
2. Solar charge controller
Solar charge controller
As the name implies. It controls/regulates electricity coming from the solar panels. It also helps to charge the battery and direct DC current from battery to inverter. It costs about 10,000 naira upwards depending on size, quality and capability.
3. Battery
battery
The battery stores electrical energy produced by the solar panels and discharges through the inverter when needed. Cost of battery varies by size and quality. A 7ah battery can cost as low as 5,000 naira.
4. Inverter
Inverter
The inverter converts direct current produced by the solar panel / battery To alternating current needed to run your electrical appliances. Except you only need direct current, you will need the inverter. As the others cost of inverter varies by size, quality and capability. A 500 W inverter costs around 10,000 naira.
Do you have an internal combustion engine. The answer is probably YES.
An internal combustion engine uses fuel such as petrol or diesel to generate power/motion.
It does so by burning the fuel internally under controlled conditions. As the fuel is being burnt a large explosion occurs inside the cylinder of the engine (where the pistons are located). Because this large explosion occurs inside the engine this phenomenon gives it the name ; Internal combustion engine. The force from the explosion moves the piston in an up and down motion which inturn transfers power to where it is needed. For instance in a car engine, the force from the explosion moves the pistons which inturn enables the car to move on the road.
The process by which fuel is burnt and the explosion that occurs and consequently the movement of the pistons is a fast and continuous process and lasts as long as the engine is on.
Examples of things that are powered by internal combustion engines are;
Train
Motor car
Generator set ( that generates electricity)
Trucks
Motorcycle
Mechanical power saw
Tractor
Bulldozer
Ships and boats
Airplanes
Mechanical grinder
Mechanical weed cutter
and so on
How to maintain internal combustion engines.
Internal combustion engines are expensive. To make them last much longer, you must take good care of them. In developing good engine maintenance habits, you must note these;
Engine oil
The engine oil is like the blood in our bodies.
Engine oil is necessary to lubricate the engines, remove impurities and keep it cool. Always check the level of the engine oil of your engine and fill up with the same type of engine oil when necessary. Check around the body of the engine or floor for oil leakages. If you suspect pil leakage take the car for service immediately. Change the engine oil with the same recommended type every 3 months.
Radiator
Bigger engines are fitted with radiators which are used to cool the engine with water. Always check the level of water in the radiator. Also always check for water leakage from the radiator.
Engine sound
Always observe changes in engine sound. If you notice an unusual sound from the engine engine , have it checked by a qualified personnel
Spark plugs
If your engine uses gasoline or petrol then it is fitted with a spark plug. When engine sound changes, or fails to start, or it is not working as powerful as it used to then the spark plug may need replacement.
Low fuel
Never let your engine run out of fuel. If you are in the habit of doing this; STOP!. Allowing fuel to finish in your engine while running can damage the carburetor of fuel injection. System. For a diesel engine you may always need qualified personnel to start it each time it occurs.
Engine performance
If engine performance has weakened. Then it’s a good time to take it for repair.
