8/30/2017 1 Comment Tips To Save ElectricityThe increasing of C02 emissions, the environmental pollution and therefore the heating up of the Earth are the most important issues of humanity. The gradual depletion of the Earth’s energy resources takes many challenges for all of us. The energy crisis has becoming more urgent that not only threats world economic growth but also peace and international security. The fossil energy sources which had been a precious gift of human nature are almost exhausted. Energy is limited and people are generating more demand for energy. If people do not save energy and have research solutions for the new energy, the energy crisis will occur.
Energy is always a difficult problem for any state. Now most of the energy that is generated from natural resources such as, coal, oil, water and gas. So if people do not save energy, it will lead to depletion of natural resources. Using electricity efficiently is always a question putting on the top priority of many households as well as businesses and organizations. Here are a few tips that you should know to see the power using per month:
1. Setting Electrical Equipment Scientific And Reasonable Proper use of electrical equipment can not only help to save electricity but also protect the environment. This measure seems to be one of the best tips on how to save electricity at home that people should know to protect environment. This measure also contributes to power saving. For example: Pumps placed in appropriate locations at home will help your tank filled more quickly. All walls in door should be painted with bright colors to make use of natural light to save some of the light power. 2. Selecting The Device To Save Electricity In fact, choosing devices that can save electricity to the best extend is a very useful tip and also very simple for people to apply. It will not take you too much time as long as you follow exactly some rules. People should not use old electric equipment because most new generations have the capability of power saving. When selecting rotating electrical equipment such as pumps, electric fans, washing machines, you should select more rungs engine speed or inverters to save electricity. With bulbs, you should use compact instead of incandescent bulb because it takes 3 to 4 times power consumption than compact. This is one of the most efficient tips on how to save electricity at home that people should know to save money. 3. Air conditioner And Fan Fan limitation of using is also the ways on how to save electricity at home. You should pay attention to area and structure of the room to arrange the fan reasonably. According to scientists, using a ceiling fan will save electricity than using multiple smaller fans. However, if your house can not use ceiling fans, table fans can be resort to. So we should not choose the motor structure, lightweight because it will heater and the performance will worse. Besides, the power consumption is also much more. Fan should be cleaned regularly. The fan is cleaned by giving oil into drive shaft and the new grease into the gearbox fan and checking the rated voltage of the device whether it is suitable for the mains voltage in your family or not. You should let temperatures above 20 degrees Celcius. Regularly cleaning the filter will save from 5 to 7% power. Putting the machine away from the wall will save 20 to 25% energy. Therefore, turn off the air conditioner for 1 hour or more if you leave the room. Remember to unplug the remote control of the fan after each time you use. Air conditional and fan are 2 home appliances that may take a lot of energy and electricity consumption so that you should use it reasonably and find the best way on how to save electricity at home. 4. Refrigerator Knowing the ways to use fridge reasonably is the best tips on how to save electricity at home. Limit the opening cabinets to help take power. The temperature inside the refrigerator should be in mode 3 – 6 degree C. With frozen regime are from 15 to 18 degree. Just colder 10 degree C is consuming 25% more power. Besides, the refrigerator also should be cleaned more often and the door must be closed. Your fridge will consume a lot of electricity if you take the food hotter than normal temperature. You should arrange the food in the refrigerator neat and tidy and avoid too tight. This method is very useful on how to save electricity at home that the reader should study and practice. The power source must be plugged in all day because if you disconnect the fridge, it will take time to connect again and consume a large amount of electricity. 5. Televisions You should not leave the screen in bright modes to help save power. Instead of using the remote control to turn off the TV, you should turn off by pressing a button on the machine. Do not watch TV while connecting to the video. Then, people always select appropriate TV size for your home area as large as for the television power. Choosing suitable television plays an important role on how to save electricity at home that all men and women should know. 6. Computers The more the computer monitors have higher luminance and color, the higher the consumption energy is. So turn off the computer if you do not tend to use within 15 minutes. Select the power saving mode of the computer to both protect the machine and hence reducing about 55% of power consumption during the down-time. If you just use the sound from your computer like music, learning English, turn off the monitor if possible offline. When using a laptop, you use the energy from the battery to save energy rather than electricity used directly. You should only open your computer when you need to work and use. Take off completely when you are done, because the “sleep” still consumes energy. This is one of the significant tips you can do with your computer on how to save electricity at home. 7. Irons Setting the appropriate temperature for each type of fabric is also one of the best tips on how to save electricity at home that people should know. You can collect many clothes to take use of the heat of the iron.You shouldn’t use the irons in the room with the air conditioner, when the power flicked or clothes are wet. After off the power, you still probably iron two sets of clothes because ironing temperature is slowly decreasing. The type of iron with non-stick substances with power levels from 1000w to 1200w is the most appropriate because this type of irons is not only comfort but also help you save power consumption when ironing. Cleaning the metal surfaces of iron will help the irons are working more efficiently and limiting the adhesive material on the irons. Quick tips on how to save electricity at home when there is no need to use the devices:

7/26/2017 3 Comments Worth of Solar PanelsA majority of consumers wonder whether the cost of a photovoltaic roof system is reasonable or not. Well, the answer depends on the buyer, the upfront money and the unit proposed. There are several variables that help in deciding the cost effectiveness of a PV array, but the buyer is in control of these, making a system within an easy grasp of any sort of budget.
Lower utility bills and energy self-reliance are the benefits of an ownership. Owning a PV array of any size proves quite beneficial. A smaller unit might only lower the utility bills a humble amount, but there’s a huge deal of freedom that comes along the unit. A large setup helps the homeowner every month if the system is tied into the power grid. The provider would pay the property owner for any excess energy supplied back to the company. Now the question arises, are the solar panels worth it? First consideration to take while deciding the answer is the size of the PV system. The huge the initial setup, the more the price. When the needs of homes are minimal, the size of a PV array is smaller, which means less investment. The required PV system will be customized for the property, and this is important, as it reduces waste and maximizes efficiency. Second consideration a consumer faces is the budget size. Fortunately, a property owner can generally find the system that can fit into any sized budget. Even purchasing a single PV array when the cash flow lets the homeowner going down the correct path. The complete system is buildable with time as and when money permits. Getting hold of a reputable provider and installer is the best way one can build a system because a single provider would give uniform service and absolutely streamlined business dealings. Every solar panel installation is equally unique as the property it’s going to be attached to. A healthy inspection by a trained professional is an absolute must to get the right combination. The installer would answer questions and help the buyer in deciding if the solar panels are worth for them. The original investment is not that expensive. Tax rebates, credits and other incentives assist a homeowner in getting the unit without spending any extra. There are various programs offered by several financial institutes that help a purchaser receive loans with low interest rates and no money down. So, are the solar panels worth it? Consumers do not often regret in making such kind of a purchase. The price of a PV system continues to fall, making ownership a possibility for many more households. A unit is an investment that pays for itself in under a decade in almost majority of cases, and then the freedom from the cost of rising utility bills is a dream realized. 6/27/2017 21 Comments Solar Panels In The MarketOne can find quite a few and wide known solar panels in the market today. The aberrations between the various solar panels will be in their costing, imperishability, architecture, design, and construction. A customer may choose one over the other due to several reasons hence it’s better to clear any doubt by the professionals in this area to demonstrate the right kind of materials which would be the best for the area where a business or a home is located. Almost all of the prominent and prevailing models of solar panels are contrived from silicon. Silicon allows the process of photovoltaic procedure to be used to congregate the energy that the sun gives off through its light rays. However, the photovoltaic cells cannot develop & process all the peripherals of light rays given away by the sun. Infrared, UV or the ultraviolet, and as well as diffused lights cannot be apprehended and caught. Therefore it means that a lot of sunlight that shines on the cells is not congregated. Due to this, several cells are used in concurrence with one another in order to be able to outgrow adequate energy to supply to a home or a business. A few kinds of cells are more prolific than the others, because they have a better rate of efficiency. In order to recompense for this atrophied energy, more state-of-the-art cells are now being created that isolate the wavelengths of light. This is done in order to invigorate and strengthen the capability to capture large amount of the sun’s light rays and be more conducive and efficient. Basically, there are two kinds of modules that are created from silicon and are thin film and crystalline. Both of these types are exactly what all the prevailing solar panels have in their arrangement and structure to create solar power as an alternative back-up energy. Crystalline is further disunited into two contrasting subsets which are mono and poly. Thin film is also divided into two different subsets which are rigid and flexible. Since the prevailing and popular solar panels also languish and suffer decreased modified production when they warm up, a system should be in a place to allow for them to breathe rightly. A convenient and decent ventilation program is also required to be installed behind the cells so that they don’t become warmer and decline it’s productivity. Additionally conductors are put up at the top of the cells, such as copper strips or silver lines. This is done in order to make a waffle pattern for most of the time as this allows the energy to easily be captured and then broadcasted. As the crystalline modules last long and are more efficient and conducive, they are also quite expensive. The thin film modules are affordable, however, the thin film modules do not have the endurance that their counterparts have. When the time comes to select the right quality product, the popular panels are the ones that most people opt to choose from that offer a proven track record for being dependable, functional and satisfactory. It is always best to go with the products that have been checked, tested and proven, and that these energy cells are no different. The retailer can also go into more details concerned with which cell may work correct for the situation. As more and more people contend to save money and conserve energy as well, the insistence for these systems still continue to increase and rise. This is the trend that shows no signs of slowing down yet. Article is posted by XsunX– Commercial & Residential Solar Solution Experts.
Which project is the largest in terms of installed capacity? As of updated on December 2016, the largest solar photovoltaic project in the world is the Solar Star power plant, located in Rosamond, California. The project has an installed capacity of 693 megawatts (AC) and started operating just recently, in September 2016. Some of the main characteristics of the project are:
The year 2017 promises to be great for solar power, as photo-voltaic technology is now capable of delivering energy at lower prices than coal when site conditions are right. For example, an 800-MW contract was recently signed in Dubai, with an energy price of 2.99 cents per kWh, the lowest ever for a solar farm. However, photo voltaic technology is still being held back by three main hurdles, and overcoming them could make solar power even cheaper and more competitive:
However, the latest developments in materials science could make it possible to solve all three of these issues with a single technology. According to the World Economic Forum, PV cells made from perovskites instead of silicon are the future of the solar power industry. Reducing the Manufacturing Costs of Photo-voltaic Modules - Solar photo-voltaic systems offer carbon-free operation, but the same thing cannot be said of their manufacturing process, which consumes massive amounts of energy. Silicon is very easy to find in nature and you walk on it whenever you go to the beach; the main component of sand is silicon dioxide. The problem is that solar modules require pure elemental silicon, and its production requires melting silicon oxide at temperatures of up to 2000°C with an electric arc furnace. Generating all that heat requires considerable amounts of energy, and unfortunately most of it still comes from coal power plants. In order to make solar power eco-friendly in all stages of the product life cycle, it is necessary to reduce the energy footprint of its manufacturing process. Perovskites, on the other hand, are made from a crystalline lattice of organic molecules, metals and halogens. The manufacturing process of perovskite solar cells does not involve the high temperatures required with silicon modules, which reduces both the financial and environmental impact. Another advantage of perovskites is that they can be stored as liquid solutions that are then deposited on any shape or surface, turning it into a solar cell! Making Solar Modules Flexible - Silicon solar modules are manufactured in a flat shape because silicon and glass are rigid materials, and creating customized shapes would be prohibitively expensive. On the other hand, perovskite-based solar modules can be deposited on any surface as a thin film of material, eliminating some of the key limitations of traditional PV systems: rigidity and weight. Both of these factors place a limit on the types of surfaces where it is practical to deploy solar power. Low weight and high flexibility would expand the applications of solar modules beyond buildings and solar farms, potentially including vehicles and even clothing. Some possibilities of perovskite solar cells include the creation of electric vehicles that charge themselves on the road, or clothing that can integrate a solar charger for a smartphone. The weight reduction would greatly contribute to cost reduction, especially in two steps of the solar power value chain:
In fact, it will not always be necessary to deliver finished solar modules to the project site. With the rise of 3D printing technology, it will be possible to deposit the perovskite film directly on the surface where it will be used. Perovskites Can Make Solar Modules More Efficient - On average, the planet Earth gets around 1000 watts of incident sunlight per square meter, with the highest potential being concentrated close to the tropics. Unfortunately, current photo-voltaic modules can only convert a fraction of that energy into useful electric power, and that is why most modules have a power rating in the range of 250 to 300 watts despite having an area of around 1.50 square meters. Silicon-based solar cells are not expected to offer significant improvements in efficiency in the short term. The top efficiency of solar cells in laboratory conditions is around 25%, while most commercial modules are under 20%, and this has not changed much over the past decade. On the other hand, perovskite cells experienced a boost in efficiency from 4% to 20%, from 2009 to 2016. The technology is still maturing, which means that its efficiency still has potential to climb higher. Perovskite solar cells could make it possible to concentrate more kilowatts of installed capacity for a given project size, while making the technology lighter and more flexible. On top of that, the use of perovskites could reduce manufacturing costs, especially the energy footprint, as well as the environmental impact. If current photo-voltaic technology is already competing head-on with fossil fuels despite its limitations, there is no doubt that solar power could become a mainstream energy source with perovskite-based modules. Complementary developments in batteries and other storage technologies can make solar modules a reliable energy source for both the day and night. You don’t have to be an energy investor to reap the benefits of solar photo-voltaic technology. Article is posted by XsunX -Commercial and Residential Solar Solution.
Think of all the applications of low temperature in homes and businesses: it is used for product refrigeration, air conditioning and industrial process cooling, just to name a few examples. When companies make ample use of low temperatures, and there is no reason for them to store energy in batteries if they can deploy cold storage instead. Low-temperature storage is an excellent complement for solar power, because it allows companies who own solar PV systems to maximize the return on their investment. Normally, companies face several energy management challenges: 1. They have access to lower electric rates when grid demand is low, but this typically happens during nighttime when most businesses are closed. 2. They pay higher energy rates when demand on the power grid is high, but this is normally during daytime when they need the most energy. 3. On top of that, they are charged a maximum demand fee which is not normally applied for residential customers. Basically, utility companies measure the highest power consumption peak in a month and apply a very high rate to it, which is based on the instantaneous demand in kilowatts rather than being based on kilowatt-hours consumed. In other words, if companies can come up with a method to shift their loads away from peak demand hours, and cover it up with free energy from solar power or low-cost energy during nighttime, they can save a lot of money. Low-temperature storage is a perfect solution for this:
When energy is at its highest price of the day, the company should ideally run mostly on cold storage, using refrigeration equipment only if they have no other choice. This effectively allows companies to deploy solar power and cooling systems together, in order to shift their load away from hours when energy is more expensive, as well as to minimize monthly peak demand charges. Let's discuss an example of commercial application of it: The combination of solar power and cold storage has already been deployed successfully for commercial refrigeration by Cold Viking Solutions, who have developed a technology called Thermal Energy Storage Cells (TESCs). This technology uses a compound developed by NASA, which comprises hydrated salts and can absorb considerable amounts of thermal energy through a phase change. When combined with an energy supply from solar power, these TESCs offer considerable benefits for companies who make ample use of refrigeration: - Although the total energy used is the same, the expected cash savings can range from 25 to 35 percent. - Up to 90 percent of peak demand can be shifted away from its normal hours, allowing further reduction of the electric utility bill. - Since there is no longer a peak in demand, refrigeration equipment can be sized smaller. This represents considerable upfront savings in new facilities or in expansions to existing ones. With a technology such as this one, there is no need for companies with a lot of cooling needs to install large and expensive battery banks for energy storage. Cold storage is more affordable and directly useful for them, so it makes a lot more sense from the business standpoint. Article is posted by XsunX -Commercial and Residential Solar Solution.
9/29/2016 4 Comments A brief History about Solar PanelsAlthough there are many historical aspects about solar panels about which most people might be unaware of. As technology continues to advance and the popularity of such green energy increases along too today, scientists had only been exploring the power of solar electricity in the early 1800’s. Solar energy has several uses and benefits as well that are highly considerable. Homeowners, particularly have become more educated about solar panels and the way of incorporating them into their very own households. Edmund Becquerel, in 1838, at the forefront of experimenting with the idea of utilizing light to create energy, also called the photovoltaic effect. Even though this exploration, there was very little in his findings anything of any interest. Over time, the use of sun as a source of power continued to be applied and experimented constantly. Solar energy, in 1860, was used to run a motor and a steam engine. It wasn't until 1883 that Sir Charles Fritz spawned the pioneer solar piece that used selenium lined with gold. Although costly and inefficient, it was the launching pad for further investigation into such kind of technology. Albert Einstein, in 1921, got recognized for his study regarding the photovoltaic process and received the prestigious Nobel Prize. As and more the scientists kept learning more about solar panels and their several power possibilities, many also tried their hands at concocting successful prototypes. Russell Ohl became the first to patent the silicon cell equipment, after which the Americans - Gerald Pearson, Darryl Chapin, and Calvin Fuller moved on with the groundwork to produce the first sunlight converting pane to generate electricity. Although further fundings by their employer, Bell Laboratories, the power source had been too expensive to parent and utilize. Interest doubled as the1970’s approached. With concerns about environment, which had become the key focus of many, research was enlivened to jewel a more efficient and affordable means of converting sun’s power and light. Whilst the power of the earlier cells cost an upwards of $300 per watt, prices were now down to approximately $20 per watt during that time. Although this decrease in price did not make the equipments accessible for an average homeowner at that time, yet the military, lighthouses, and the off-shore rigs began to install them to advocate in their energy needs. Extra upgrading, added economical materials, and a heightened popularity lent a larger hand in depreciating the overall cost of this green energy source. In doing so, home and business owners, thinking of solar in their business, now have learnt more about buying solar panels and the benefits of it such as reducing energy costs, tax benefits for commercial solar, etc that they have to offer. They have found that the use of solar are very cost effective utilizing this renewable source of energy and help the environment. The solar equipment comprises of silicon semiconductors that are horsed in their frame to an unobstructed spot on the roof. The instrument will then trap the incoming sun rays, and convert it into electrical power for various used inside and outside the home as well. The instrument can produce power that will run everything from the washing machine, refrigerator to the heater in the backyard swimming pool and many more. This equipment has been built to withstand the elements and provide energy for future several years. By making an initial investment, homeowners substantially lower their own utility bills. With a minimal maintenance on the equipment, consumers can see their monthly power bills decrease over 60-80%. In many cases, the summer sunshine produces electricity above and beyond a single home’s needs, hence, allowing power to be stored for future use or sold back to the provider utility company. In becoming more educated about solar panels, homeowners and business as well benefit largely from the hard work of the many determined inventors over the years.
