The basic human needs are food water and clothing; however in our modern society we may as well add one, electricity. Society in most culture will not function if we were out of electricity. Since the inception of its use in the late 19th century, electricity has become the most widely used energy source and has led to the improvement and daily usage of modern conveniences; from light-bulbs to refrigerators, stoves, irons and washing machines and more high tech devices such as computers, stereos and even some cars now.
With us extensively using and exploiting fossil fuels we are causing a lot of harm to the environment. Our “gargantuest” demand for energy is the cause of greenhouse gases effect, depletion of natural resources, and causing hazardous work conditions for some of us (those mining the coal and stationed on oil rigs). Further more it has also led to the changes of our climate which is generally referred to as “the climate change.” However there is hope, these changes can be reversed and these adverse effects can be only historic facts. In the light of these particulars alternative energy resources such as solar panels are viewed as a solution. Integration of solar power technology in houses and buildings is getting some prominence especially in Europe. As demand for this type of clean and renewable energy is increasing, research and development in this sector has brought some great improvements to solar panel production; however the upfront costs associated with the procurement and installation of these devices are still significant.
The cost of a solar panels system and its resulting power output depends upon its use, the materials it’s made of, and its overall quality. These factors will furthermore determines the life span of the overall System. A solar arrays of 55 watts has an average cost about $98.00, which is about $1.55 per Watt. This is usually bulk price and does not include installation. A small-scale off grid of 500 Watts for a home professionally installed cost around $3,455.00 that is $6.91 per Watt. This price is the complete system, equipment plus labor. The price for a medium-scale off grid installation which would be about 810 to 1400 Watts cost about $6.79 per Watt while a large-scale off grid house installation of 2688 to 4032 Watts would be average $5.48 per Watt. This may seam a bit expensive but consider that the cost of a solar system is easily recovered down the road as there would be no electric bill for the life of the system that is for the next 20 to 25 years down the road. Albeit an occasional maintenance cost
The above comparison clearly illustrate that the biggest expense associated to such system is the installation fee.. The relatively high price of professional installation is mainly due to the few qualified skilled technicians as solar energy is an emerging technology. With these in mind it is also advisable to fully benefit from such installation, energy efficient appliances should be used. This will extend the lifetime and efficiency of the solar system.
A solar panels system is very delicate and sensitive to dust and other particle pollution that may obstruct the cells as such proper maintenance should be considered. However, newer models are manufactured out of less tensile and pollution proof materials, this way strengthening them, increasing their resilience and functionality. To optimize the use of solar panels, proper orientation to the sun is paramount and the geographical location will also affect its performance. The best way of overcoming these hurdle and get the best value for your money is to pick a trustworthy solar power installer or technician,
As mention earlier once installed and excluding the cost of maintenance, the cost of electricity generated by solar arrays is relatively zero. On the other hand using fossil fuel in power plants there is a permanent need for fuel as long as electricity is generated and “that fuel” needs to be purchased. With solar panel technology, as long as the sun keeps hitting this planet, one can generate all the electrical energy that is needed.
At first glance it may appear expensive to use solar power however, there are more benefits than disadvantages. Compared to the small but cumulative operating cost when using fossil fuels base electricity, the savings with solar panels utterly surpass the other. Solar energy is safer, cleaner and eco-friendly. As governments starts considering these benefits and demand from ecological consumers increases, the trend of solar power utilization will eventually decrease the initial cost of solar power. Everything on our planet, Earth, is linked, and truly Earth is linked to the sun, its original and foremost energy source.
