solar electric backup for disasters? not as easy as you think
Fires, floods, tornadoes, echoes, hurricanes, and earthquakes quickly destroyed the lives of some people, but for many, they caused lingering problems. With the maintenance of the power line, the power may last for several weeks due to high temperature pressure, medical equipment failure and more common deaths. The fire in Colorado hit my area badly last month; Some areas are still waiting for power to resume. An estimated 3. On the east coast of last month, 7 million people lost power, many of whom lost power over a week. So why not cut off the power company\'s wires to your home and completely out of the grid in the middle of the city or in the suburbs? In any case, power companies are raising rates every year. Throw some solar panels on the roof and a wind turbine in the backyard. It also looks like there are a few black boxes that look interesting, just order them online. Fortunately, it\'s not that simple and cheap. The question is, how do you store energy when the sun is not bright and the wind is not blowing? If the grid is off, solar panels and wind turbines without battery backup will not power anything in your home. This can only be done with battery packs or engine generators. Let\'s face it. when we store a lot of electricity at a reasonable price, we insist on 1859 technology: lead. acid battery. Gaston play, Thomas Edison and Henry Ford will immediately recognize the batteries used off-site today Grid power systems, and may comment, \"It\'s strange that they haven\'t changed much in these decades. . . \"That\'s the problem. There must be high- Technical options such as the nickel metal hydrogen battery used by Toyota Prius, the lithium ion battery in the Tesla sports car ( Also in your laptop) And, of course- Hydrogen fuel cell. These new energy storage technologies are not yet mature. - At least they won\'t be able to afford it or can even power a typical home within 24 hours. To make matters worse, all the batteries are worn out. Pulling the battery pack too low too often, or keeping it too long, you may have only one to four years of life, not the eight to ten years that are usually expected. Amortized the cost of batteries and installations over the years, you can pay a fairly expensive \"battery Bill\" every month just to have them. Electric car backup power? Japan\'s 2011-magnitude earthquake and tsunami prompted Japanese automakers to begin offering electric and hybrid vehicles the option to power lights and appliances during power outages. Toyota says 12 cars are full. The 2012 estimated gallon tank with power inverter option can power the home for 2 days in full 1. 5 KW output, but this still needs to plug the extension cord and power strip into the house and insert the electrical appliance into it. Work at a critical juncture, but not particularly safe or convenient. Both Mitsubishi and Nissan have announced that they are working to standardize systems and equipment so that cars can supply power to household power circuits. Sharp shows the new \"smart power regulator\" they are developing to solve the tricky problem of making different cars, with battery packs and home power systems sending power back and forth between each other. Great concept, but unfortunately \"in development\" is an effective phrase now. A sensible emergency home-to-home approach has picked up average electricity consumption in the United States. S. Homeowners consume about 33 KW. Energy every 24 hours. Lead- A 24-hour standby acid battery at this rate will be put into use for about $9,600, weighing almost two tons, for only 7 to 10 years, occupying the entire small room. Lithium ion battery pack to do this- Say from Tesla sports car- It will cost $36,000 at a 7-year rated life. These costs are only the cost of the battery pack and do not include all the black boxes needed to connect the battery to the home. Instead, I suggest that most people take a more sensible approach. The more serious you are about the backup power supply, the more you will put it on this list: unless installed at high altitude, the wind power system is a very ineffective waste of money --- The small wind industry standard is at least 30 feet higher in any direction than anything within 500 feet-- Most places have strict management of such high-rise buildings, especially in residential areas. So, wind is not an option for most people. However, if your website and climate are suitable for renewable energy and your utility will pay you a favorable price, you may have the opportunity to reduce your electricity bill to close to zero, get a federal state or local tax credit and have plenty of power during long power outages. Contact NABCEP- Certification system installer for direct facts of renewable energy. Before the lights go out, be prepared before the next disaster comes. But, without a lot of research, don\'t jump into any backup generator or solar solution, especially if you need to power critical devices such as medical devices. If the fridge is filled with meat worth hundreds of dollars, even the fridge can be considered a key device! Make sure any power backup solution you choose can run everything you need at once- Power in Watts- No matter how long it takes you, it can stay the same- Energy in kilowattshours. If you have any questions about what you are doing, please consult a professional and remember: it is impossible to be true if it looks too good.
