Energy is the soul of the modern era. The depletion of our conventional energy sources like oil and gas has troubled the scientific community since long and they are looking for alternative energy resources. This research for alternative and environmentally safe energy sources has lead to development of fuels like ethanol but the biggest, though a bit expensive to start with, revelation is the use of solar energy for powering up our life

Solar Energy

Solar energy is an un-harnessed area with vast potential. The energy reaches the earth in form of light and heat which is used by the life on earth. But the light rays have a capability to produce energy once they are used by the solar cells made up of photoreceptors. These solar cells may be used to power the wrist watch or power an automobile. The principle remains the same and that is to convert light into electricity.

Solar Power Mobile Charger

Solar power mobile charger is used for the purpose of charging from direct sunlight. It powers itself from the sunlight or any light source and in turn supplies this electric current to the battery of the mobile set. These power chargers come in a wide range of capacities and you must choose carefully the correct charger giving the right amount of current in units of amperes and watts to power your mobile phone. Also the compatible accessories like wires with suitable ports for plugging into your battery must be procured.

In Case of Emergency

Mobile phones are an ideal way to communicate from far off distances and they are the means for calling help in an emergency. However, their dependence on battery and limitation of talk time or standby times may cause them to be out of function once you need them the most. Solar power mobile charger can store energy up to hours depends upon the storage and capability of device.

Steps To Make Solar Power Generator

Are you interested in making a solar generator within a budget of 350 USD? Then you have to follow the following instructions. The cost of the solar generator entirely depends upon the material that you use while construction. The solar generator will generate up to 100 watt-hour of electrical energy if the solar panel of 20 watt receives solar energy for more than five hours per day.

Important components of generator

Important components of generator

In this particular design that you are going to learn, we are going to use a rechargeable battery that can store more than 400 watt of energy.  First you have to pick a reliable solar panel that is rated at 12 volts. You can easily get such solar panel for less than 175 USD. You are suggested to get a charge controller of 4 amperes, which is readily available for 25USD. Battery is the most important factor of this design. Therefore, you should get a 32 amp-hour battery that is available for 60 USD.

Power inverter and installment of components

You can attain power inverters for less than 30USD. Next you are recommended to grab a voltage meter that is going to be used to monitor the load on solar generator. A wooden box or a plastic cooler are suggested to be used for the enclosing purposes. You have to drill a spot on the cooler to fit in the parts that are being discussed before.

Precise connections

The next step includes the connection of the insulated wires with the battery from the meter. Keep in mind that you have to connect the positive terminal first. Read the full story

In this post, you will be taught about something called circuit. Electrons do not work in air to get attracted by positive charged atoms. There is a medium in between which helps link the electrons to the positive charged atoms. The link is what that connects the negative area with the positive area. This is the link or the bridge in between them called as ‘circuit’.1112electronic_circuit

So, circuit is important for the passage of electrons towards the positive charged atoms. The electrons movements, high or slow, depend on the resistance of material. If the circuit is not carefully observed, the number of electrons moving fast at one time can damage the circuit in the process. In our previous post, we learned that there is a strong attraction between the opposite charges and  also we have learned  that  how we can build a circuit between the opposite charges.
