There are 2 main types of solar panles: thermic solar panels for warming water and photovoltaic solar panels for producing electricity. For both of them the installation procedure is the same.

In order to determine the cost for installing solar panel you need to identify the place where to install them. There are a few ways of installing the solar panels for your home:

• on the roof of house - mounting the solar panels on house is the most convenient and frequent but in the same time is the most difficult. When installling solar panels on the house it’s better to contract a specialised firm to mount the panels, because it envolves some risks and if not done correclty it can produce damage to the roof. The required materials cosist in supports for the solar panels, parts to fix the solar panels on the roof and cables or pipes to link the panels to the main installation.
• near the house - if for various reasons is not possible to mount them on the house the panels can be installed somewhere near the house where is enough place; the place should not be shadowed by trees or other buildings. The solar panels used to warm water might require an additional pump to circulate the water between the panel and the main installation.

Once you decide to the place where to mount them all you have to do is to contact a local firm to find out the cost of installation. It’s not recommended to do it yourself if you want to put it on your house.

If you are planning to make or buy a solar power system in your house then you need to consider some important factors. Without proper understanding of some of the key factors it will difficult for you to maximize the use of your solar power system. The most common factor that come into consideration before purchasing or buying a solar power system are cost, Durability , Longevity ,Warranty. Most of the people give to much emphasize of the cost of the solar power system they forgot the other factors. All these factors are equally important in establishing a solar power system. But many people forget to consider a key factor in this process. And that is the power measured in watts of the solar systems. That is very important in the generation of power.
Different watts are available for solar power system in the market. For example 5 watts, 10 watts ,15 watts ,40 watts , 50 watts ,100 watts , 200 watts and many more. People need to have a good idea about their required watt because the cost of the solar power system is associated with the watts. The purpose of the user may cause different requirement of watts. If the solar power system will use in small organization it way require more power(more watts). But if the purpose is to use it in the home than the requirement will be much more lower. You have to be very much sure of your requirement because Watts are related to the output of each panel. A 100 watts solar power system can not produce more than 100 watt of electricity in a normal condition. For other different watts the output will be same as the watt per hour.

To have a greater efficiency in the output of the electricity, the watts of the solar power system should equally support by the physical size of the panel. The combination of the watts and physical size can be vital in the final outcome.

Understanding the watt requirement can be very crucial in the overall success of the solar power system. So creative planning is essential in the designing of the total requirement of your solar power system. Once the solar power system is set up it is very difficult to change it again. So be careful in your requirement and set up the proper solar power system and achieve a great level of generation of electricity.

Some of the most common equipments for making solar panels are electric stove, micro-ammeter, Sheet metal shears, Tap water, plastic bottle or glass, Electric drill with sand paper, Safety goggles, and copper flashing.

Solar panel making starts with the cut the copper flashing. It has to be cut in a square or rectangle so that it fit the size of the electric burner. To cut the copper flashing you have to use sheet metal shears. You have to conscious about the cleanliness of copper flashing. The use of sandpaper helps to protect of any sign of corrosion before proceeding. Now your job is to turn on the burner and put the copper flashing into that. But you have to be very careful in doing this. A thick layer of black cupric oxide is necessary in this process which can be through the half hour cooking of he copper flashing. After the cooking is finished it requires some time to cool down. You have to be patient here because it may took some time.

Before proceed further at first you have to make sure that you completely remove all of the remaining bits of oxide. To ensure this you have to Scrub the completely cooled copper under running water. Now you have to cut a piece of copper. But be careful in the size of this new copper. Because to be the same size of the original one. Then efficiency is required when you attach both panels using the alligator clips to the inside of the glass or plastic bottle with the top cut off.

Lots of concentration needed in every step. Mistakes in the earlier steps can cause a failure in the making of perfect solar panel. To turn copper plate into positive terminal of the meter you have properly connect the lead of the alligator clip. At the same time negative terminal should then be connected to the cuprous oxide plate. To ensure dryness of the clips enough solution to barely cover the bottom of the plates is essential. With these your solar panel making is completed. Put the solar panel outside and see the effectiveness.

Materials Needed To Build A Solar Car
A solar car can be built easily with the availability of the following basic components and materials.

• The Frame, of the car should satisfy certain important design features, which mainly decides the efficiency of the solar car.

• The Solar panel is an array of solar cells, which are also called the photovoltaic cell.

• The Power trackers are used to convert the electricity produced by the solar cells into usable form of electricity.

• The battery - stores up the energy that is harnessed from the sun to be used at times when the sun’s energy is not available, i.e., at night or on a cloudy day.

• The motor and its controllers, which make the vehicle, move by providing the rotational motion to the wheels of the car.

• The car accessories like the seats, front panel glass, the wipers and others required.

Design Criteria
The efficiency of the solar car depends on how good the design criterions are met. The first design condition to build a solar car is that it must be light-weighted. The light-weighted design of the car is required to get a good Power efficiency which means is the electricity obtained is used to produce maximum rotations of the wheel or long distance traveled. So the frame material should be light weighted usually light metal alloys are installed. The body of the solar car has to be designed in such a way that it would provide space for the solar panel and also give the aesthetic look for the vehicle.
The solar panel should be installed in such a way that maximum amount of sun’s rays can be captured. In some designs, the panel could be either automatically or manually rotated to face the sun as the vehicle moves, to obtain maximum efficiency. A simple electrical circuit, which is used to convert the energy output from the solar cells into usable form of electricity, is installed in the motor side, called the power trackers.
The battery is attached to directly to the output of the power trackers. This is usually a normal backup battery that is used in the regular rechargeable gadgets. The output of the battery is used to drive the motor, which is normally a 3-phase AC motor, which demands the need of the chopper to convert DC battery power to AC power. There is no transmission unit involved as in the case of fuel driven vehicles here, a simple belt is used to transmit the energy to the wheels from the motor.
The other automobile design concepts apply to the solar car too, except for the special focus on aerodynamic design and less friction design are given more stress on.
Apart from this, depending upon the scalability and use of the vehicle, the brake and suspension system can be designed. Thus, a solar car is a simple scientific concept, when implacable to be used to by common Joe will be a dream come true project for the whole of the automobile industry.

The solar energy is the best source of abundantly available renewable energy, which is now being used to produce a variety of useful products. The thought of using this renewable energy to drive the automobiles arose in the later half of the 20th century and the first 100% solar vehicle drove on the earth in 1986. With the rising prices of the diesel and gasoline fuel, an alternative source of renewable and cheapest form of energy is the need of the hour. So, it’s a timely act to take up the nature-given sun’s energy to drive our vehicles.

Though solar cars have some practical difficulties to be used as a domestic mode of transport, constant research and development in this field would yield us a cheapest mode of transport. To make this invention more accessible one should understand the basic working concept behind these sun-driven cars.

The Basic Concept

The solar car collects the solar energy from the sun and utilizes it to run the vehicle. The solar panel tracks the sun’s energy and converts into the electrical energy. The power trackers are essential component that converts this raw electricity to a proper system voltage. This electricity is in the DC form, so the motor controllers convert it into the AC voltage. The voltage drives the motor, which in turn rotates the wheels making the car run. So, to understand the working principle the components of the solar car can be analyzed under two categories – the mechanical components and the electrical components.

Mechanical Components:

• The frame of a solar car is designed to be quite compact and the only aim is to support other components of the car and a minimal aesthetic features.
• The body of a solar car has to be designed crucially, because it provides room to the solar panel that is considered as the heart of any solar gadgets. Also the aerodynamics of the car has to be within requirements to reduce air drag while in operation.
• The solar car use tires that have low rolling resistance.
• Solar cars use hydraulic disk brakes like a normal road-run automobiles, so with this kind of brake system, a solar car can be brought to halt from 30 mph in only 70 feet.

Electrical Components:

• The solar panel is the heart of the solar car, which is the center that converts solar energy into the electrical energy. It consists of an array of solar cells. A solar cell is made of a semi-conducting material like the Silicon that is doped with a specific donor. Also there are Gallium arsenide solar cells, which are 10% more efficient than the normal silicon solar cells. The GaAs cells are used in solar space vehicles.
• Batteries: The solar car uses the sun’s energy! The next question would be what if suddenly the weather becomes gloomy? Should I have to lock my car and walk my way? No! The battery in the car acts as a power backup for the car. In general Lithium ion batteries are used, which are similar to the ones used in our laptops and cell phones. A study says that, with 25 kg of these batteries charged in your car, you can drive 200 miles without sunlight.
• Motor and its Controller: The motor of the solar car is built into the wheels meaning that there is no transmission unit. One rotation of the motor equals to one rotation of the wheel. The controller is used to convert the DC power into the three-phase AC that can drive the motor. So, the controller basically acts as a chopper. Adjusting the frequency of the AC power can control the speed of the motor.
