Solar is a sustainable use of clean energy. In the search for sustainable development of human society, energy-saving building on the increasing use of solar energy is getting worldwide attention.
The status of solar energy use in United States is getting better!
In United States, total energy consumption in building comes up to 30% -90%. It is becoming a certain form of economic development constraints role. Therefore, American development of solar energy is growing very rapidly.
New panels could be laid out flat on any surface whether it is a rooftop or ground. These panels have also found their place on our boats hence we have a solar panel boat that derives its energy from sun.
For centuries, we have been using wind power and muscle power to drive boats along waterways. At that time, the boats were just a wooden mass built to carry goods and passengers. Invention of the motor engine that runs on fossil fuel changed the way boats were driven. The boats were fitted with large engines that could run the boat even on rough waters and carry more goods and passengers. Today boats run on electric engines and require a considerable amount of energy. The traditional engines are no longer beneficial and we want a new engine that is light weight, fuel efficient and is as powerful as the motor engine. The answer lies in solar energy and boat we are looking for is solar panels boat.
There are different types of solar energy that are used today. You ask how many are there. According to recent studies, there are three basic types but we will break it down into five different categories. Below I have listed each type and will describe each as it relates to the different uses.
Photovoltaic Solar Power-Energy that is created by converting the suns rays into electrical energy is called photovoltaic. I am sure you have seen solar panels on houses or businesses before. These are the devices that convert the solar energy into usable electricity. In a simple form it can be used to power solar lighting, examples of this are traffic signs, yard lighting, or security applications.
Passive Solar Energy-Passive solar energy can best be described as using the sun's energy without the use of mechanical devices. One example could be the energy from the sun concentrating heat on a black painted block wall which in turn would warm your house. Another example could be how the sun
With our current economic melt down and energy prices fluctuating daily, many of us are thinking of installing solar panel power to contribute to our homes' energy needs, and reduce our power bills.
But how much solar panel watt power do we need to say halve our power bills? And how much will that power cost us to install?
Here is a four step process that you can follow to answer these two vital questions:
1 - Calculate Daily Power Used:
To do this, get your last 12 monthly power bills and calculate your average kilowatt hour (kWh) usage per month. The reason we use 12 is because our power consumption fluctuates with the seasons. But if you do not have all your power bills, then simply use last month's one.
With tax breaks and economic savings, many people are implementing solar cell technology for homes. These solar cells reduce electricity costs while providing a renewable energy source that can end up paying for itself. This article discusses how to get the most power for the cheapest cost for solar cells.
Solar cells for homes can be very expensive, often being priced for at least one thousand dollars. The cheapest cell on one site was going for approximately seven hundred dollars, but was only rated for 60 watts. The trick, then, is to find a solar panel that can give a good power output, but be relatively cheap.
The best way to achieve this is to build your own solar panels. The cost of building a panel can be as little as $150, maybe $200 if you could find a good step-by-step guide with instructions and videos. A solar panel that has been built at home can be rated as high as 100 watts.
Most sites that sell 100-watt solar panels price them at around one thousand dollars. If assuming a home-built solar panel costs $200 to make, then for same price as buying a 100-watt solar panel, you could make a 500-watt solar panel. One site advertised individual solar panels for $15. A panel requires nine cells and if extra costs are calculated at $100, a cell could still be built for around $250.
That means even at that price, one could still make four panels rated at 400 watts total with the cost of buying just one 100-watt cell. Comparatively, the next closest panel would be a 50-watt rated panel that sells for around $350.
The bottom line is that in terms of getting the most amount of power for the least cost, buying solar panels is not even an option. The only true way to get cheap solar cells and panels is to make them yourself by using an easy to follow instruction guide. This will ensure that you will get the most economical solution that will pay for itself in no time.
