Using solar lights in garden can bring great advantages. Because of their many benefits, these are getting popular than electric lights. Although, their initial cost is higher than conventional lights, these prove to be more rewarding in the long-run.
How solar lights are convenient to use?
Since no wiring, switches or sockets are required, these are not difficult to install. You can easily set these for accurate placement. These work equally well in your lawn, garden or backyard. You can move these anywhere you like.
Using solar lights is cost-effective
Using these solar lights saves considerable amount of money. These are fairly economical. The only source of energy they require is the sun. You don’t have to pay for hefty monthly bills. Thanks to nature that provides solar energy absolutely free of charge. However, the price for solar lights can be higher than normal ones. But, their long-term advantages are worth the cost.
Conventional lights versus solar lights
Another big difference in solar lights and conventional lights is that these produce a soft glow. These work well to lighten driveway, patio, garden path, decks and sheds. Sufficient light is produced to illuminate all areas inside and around the garden.
How sun-powered lights work?
Solar garden lights absorb sun energy that strikes their surface. It is then stored during daytime. At night this retained heat energy gained from sunlight is released. That helps brighten up the area around.
Main components
Each solar light consists of a solar cell, which is surrounded by a case made of plastic. It rests at the top area. A standard battery is wired with solar cell. This is rechargeable and gets energy from sunlight during the day. It then lights up at night time.

Natural resources of fuel are at a risk of being eliminated due to their consumption in very large amount. Scientist are trying to find new ways of producing fuel. One of them is the solar energy. Solar systems have been invented which convert heat energy into electricity. These solar systems are now in use and are cheap source of electricity. To understand the whole working of the solar energy systems, one must understand about the basic thing that is “Solar cell”.
Use Of Silicon In Solar Cells
The world has progressed rapidly in the field of solar energy. It is easy to use and is cheapest form of energy. To understand about solar energy system, one must start from basic level.,, a solar cell. The basic component of the solar cell is the semiconductor used to convert heat energy into electric charge. Many elements are now being used for this purpose but the best element that has been used from a long time and is still a part of many solar devices is Silicon. The guide line for solar cells is provided by the silicon structure in a photovoltaic (PV) cell. The current is produced in these cells by movement of the electrons from their respective shells. To move more electrons, additional impurities are added in silicon.
Producing Electricity From Solar Cell
A solar grade is made up with a crystalline structure. Semiconductor used in the cells is Silicon atom having three layers holding electrons. The no. of electrons increase in the center of atom. When the electrons from the outer shell of silicon escape, electrons from inner shells move to replace them. This moving results in creating a locked structure. Due to this reason, most of the silicon solar cells ape P-type or N-type silicon cells. N-type cells are added with the impurity that is mainly phosphorous which helps more electrons to escape from the outermost cell of silicon atom. Read the full story

These days the solar technology widely spreading and more people are converting their home applications to the solar energy. There are a number of indoor and outdoor lights that work on the solar energy, and this energy is also used in cooling and heating the living space.
Thermal Expansion Tanks
Expansion tanks are considered as a necessary part of the closed-loop solar water heating system. In this system water does not enters the solar collector. a mixture of water and glycol is used as heat flow/transfer fluid. During the operation the fluid is heated up by solar energy in the solar collector. When the fluid travels to the water tank that is mostly inside home there the heat exchange takes place. When the glycol is heat up it expands therefore, expansion tank is required.
Thermal actuator Functions
The main function of the thermal actuator is to prevent the freezing of the water inside the solar collectors or pipes. The actuator also act as tacking system for helping the collector to exactly position itself in the direction of the sun and resets at night so that collector can start functioning in morning. Actuator can be driven thermally or electrically.
Thermal pumps
Thermal pumps are used as an alternative of the energy systems to cool or heat the living space. These pumps draw heat from earth, underground water and from many other sources. The pump uses the temperature of the earth 6 to 12 feet below the surface to preheat or cool the indoor air.
Solar lanterns
Before the invention of the electricity lanterns were used for lighting. Now when you go for camping or a place where electricity is not available lantern are required there. Read the full story

Solar technology continues to advance and most products of solar cell technology are under research. In the year 2002, a well known group of U.C Berkley chemists first time discovered a feasible way to manufacture plastic solar cells. Even though, plastic solar cells that were manufactured by using this innovative method were not as efficient as standard solar or photovoltaic cells of that time. However, the new technology brought many useful aspects with it like affordability, flexibility and potential to give renewable electricity.
New Advancements in the Solar Cell Technology
Due to the flexibility of plastic, the new technology widened the horizon of solar cell technology. Solar or photovoltaic cells were directly placed into the plastic in which there were tiny nanorods were dispersed between the electrodes. The entire device could be painted or sprayed on materials like clothing or other materials. On such materials the device would generate sufficient electricity to power radios, low-power devices and small computers. These devices are far more convenient than the huge and heavy solar panels that need a confusing or more complex installation. The installation of heavy solar panels can be done only with the help of expert solar contractors.
Increased Power of plastic Solar Cells
The power of plastic solar had increased to great extent since the year 2002, when these cells practically started producing 0.7 volts at the efficiency of 1.7 percent. By the year 2005, these solar cells became able to convert up to 6 percent captured sun power into energy. Read the full story
