Solar Panels

Solar panels are special devices that harvest the sun’s light and turn it into energy that can be used for a lots of things. They are also referred to as active solar power producers. The solar panel is made of a lot of solar cells. These solar cells, also known as photovoltaic cells are arranged on the panel’s surface in a grid like pattern. During the day if exposed to sunlight these solar cells will collect the energy that comer from the sun and transform it into electrical power that is stored in special batteries attached to the solar panel.

Solar panels are usually made of crystalline silicon that is used for the microprocessor industry and of gallium arsenide which is used only for making the solar cells. Modern solar cells are recently made of amorphous silicon alloy and this is why you might find them under the name of A-si. Using the amorphous silicon technology in building up a solar panel will make the new product be more durable, thinner than the older ones and more efficient.

Solar panels are not used only by regular people for day to day activities; they are also used in space for the solar projects. These solar panels are made up of gallium arsenide through the molecular beam epitaxy process. P-n junction diodes are implemented to the solar cells included in those solar panels making the whole system working at higher standards that we could ever imagine. Due to the high costs that are involved for building such a great solar panel they are not rentable for the everyday activities.

New solar panels can be made of plastics. What is more amazing is that they can be overlaid onto a laptop screen and provide enough energy for its well functioning. Scientists are trying to make these plastic solar panels work at a light outside the visible spectrum of light. If succeeding, the operational efficiency of these solar panels could rise up to 30%.

People often wonder how much energy a solar panel will produce as they want to know if their needs will be covered by the solar panel they want to buy. It seems that exposed to a direct sunlight a solar cell of about 1/5m in diameter will create a current of 2 amps at 2 volts. We must consider that solar panels situated on earth will never produce the same output as the solar panels exposed directly to the sunlight due to the Earth’s atmospheric interference.

Solar panels are expected to live 20 or 25 years. In time they get exposed to overheating and get physical worn and their output will decrease. When going to buy solar panels for your property do not look that much at their size, try to look at the dollars/watt ration first and that is how you will best determine their efficiency.

It is best to talk with a specialist before buying solar panels. Do not trust solar panel dealers as they might try to convince you to buy something that will not cover your electrical needs, or something that will produce too much energy for your daily activities.

Reliability Of Solar Panels

When talking about saving money by implementing a new technology and giving up the old one used, in any field, all people are pretty reserved and need to thing things carefully

As the new solar technology has implemented on the market, a lot of people, one by one, become more and more certain of its utility and of the fact that it saves a lot of money from the electricity billing.

Solar technology uses solar panels that are created for capturing the energy provided by the sun and transform it in to power we can use for our electrical home devices. All this comes for free the only thing that has to be paid is the solar panel and its installation process. Some people want to have an exact balance of how much money they have to invest in such technology and how much money will they get back from this investment.

We can say that the solar energy is 100% reliable, as we all know that if the sun’s energy would drop then the earth would have to struggle to support humans and any other life form on it for sure. What we can not say is if the methods on how we use solar energy are 100% reliable. Until now it seems that the modern solar panels have proven to be the more efficient in harnessing solar energy. Of course the technology we use for transforming the solar energy into power is still not completely developed yet, and needs a lot of improvements that will probably come in time as science discovers more and more useful elements for us. All we can say is that as time goes by improved solar energy collectors appear on the market and we can hope that in a few years solar panels could support an entire household with no problems and at 100% reliability.

A lot of people have bought solar panels and have noticed that they save a lot of money by not paying such high electrical bills but the thing is that not all people can afford to buy expensive solar panels that would ensure them a high output. Some people go cheap and buy low budget solar panels. Their expectations are for sure deceived as such panels can not produce the same quantity and intensity of power as more expensive panels do.

Those who want to save money should consider investing some money into solar panels and then results will be seen on long term. Installing solar panels can be made by anyone who possesses some plumber skills and you should not be afraid you might get electrocuted as you won’t work with any wires.

Solar panels can provide enough power for heating your house, fro warming your water, for cooling your rooms during hot summer days and for lighting your garden at night. Try using solar panels and you will not only save a lot of money but you will also protect the nature by using less fossil fuel.

Solar Security Lights

When looking at solar power a lot of people first start with installing outdoor solar lighting systems on their property. They mostly think that such a system will make their garden more attractive and will allow them to take relaxing walks through the garden as their paths will be lighted. What not all people know is that outdoor solar lighting systems can also be used as solar security lights.

Solar security lights have the same concept of functioning as the outdoor solar lighting system has except for the fact that it does not light the garden all night long. Solar security lights have a moving sensor incorporated in their structure and every time someone walks through your property the lights will turn on and will let you know someone is out there. Such a system is useful for your family members if they come late from work or from a date and they need a lighted path towards the house. Intruders will also get surprised by the solar security lights and this way you can apply the needed measures before they do anything against you. Some of the solar security lights come even with an alarm attached to them and they can scare away and stranger from your property.

Solar security lights are easy to install as they do not require cables. They do not depend on the electricity that comes from your plugs as they make their own electricity from the solar energy.

Solar security lights have photovoltaic cells incorporated and they get their energy for lighting from the sun. This means your outdoor lighting is made for free. All you have to do is place the solar panel of the solar security lights in a place you know the sun light will reach it during the day. These solar panels are not attached to the solar security lights so they can be placed anywhere you like at any distance from the solar security light’s place of installment.

Sometimes the solar security light might turn on if a dog or a cat passes through the area that is kept under monitor. In order to avoid being disturbed every time this happens you need to fin tune the solar security system. Most of the solar security lights work with a 6V halogen bulb but the newer models have incorporated Light Emitting Diodes so don’t be surprised if you find such a thing on the market.

Solar security lights can be found in different capacities. Some might need only a few sun light exposures for providing a decent light during the night while some might need to stay longer in the sun light so that they can offer the same output as the previous ones. You should buy your solar security lights depending on the sunlight that is expected during the winter months in your area of residence.
