OK.....let's say you added up all of your demand as being 25kwh or 25000 watts per 24 hours. Next you have to figure out how many "peak" hours of direct sunlight your area receives each day. You can use charts that can help you with that right here. Then you take the correct peak daylight and use that to divide into the daily wattage use. Let's figure you get 5 hours of peak light... 25000 watts / 5 peak hours = 5000 watts per hour. This will mean that you need to put in a 5000 watt (5kw) "stand alone" power inverter. Basing your requirement on only peak Sun/hours will allow for any possible inefficiencies that might be present, because obviously the Sun is shedding sunlight for more than just 5 hours.
You will definitely want to have some way to back up your stand alone solar system, so you can be at ease knowing you will have a continuous supply of power when the Sun goes down and on cloudy days. Batteries are certainly the most utilized for this purpose, particularly, "deep cycle" batteries. Regular car type batteries are just not well suited for this type of application. These equal types of batteries are used in toroidal transformers the same manner in conjunction with wind/turbine power systems. There are calculators out there on the web that can assist you in sizing up your battery bank, but it's always good to know the old fashioned way (with our brain!).
As an example we will base the battery requirements to allow for emergency/nighttime power of 48 hours, or 2 days. It's not that difficult to figure out; we have our daily requirement of (25kwh) 25,000 watts; now we just double that figure to (50kwh) 50,000 watts; divide this by a 96vdc set up (best for this application) and we come up with a total amp/hour (Ah) requirement of 520Ah...now we need to double this figure (to cover depth of charge at 50%) to be 1040Ah. solar batteries should only be discharged to 50% of its total rating to prolong its life. Most regularly, residential systems use 12v batteries, so we will use some zero maintenance Trojan Deep Cycle Batteries model# 6D-AGM 200Ah. We have a total battery bank size of 1040Ah divided by each battery size of 200Ah to get 5.2 batteries; round this figure up to (6) batteries (never round down). This battery bank will all equate to (8) 12v batteries wired in series to get the 96vdc needed by (6) batteries wired in parallel to get the 1042Ah needed. You would end up needing a total of (48) 12v 200Ah solar batteries for this project. The terminology for this would be 6 strings of 8 batteries.
The solar panels required are sized pretty much like the batteries. Take the 5kw system we came up with and go from there. Find some top rated quality modules you can find and just take their wattage rating and divide that amount into the total required wattage of 5000 watts. The charge controller in this example would be one rated for 96vdc by 60amp (these can handle up to 5.7Kw).
As was written earlier, there are calculators on the internet to help you through this entire process; however, even programs can mess up on you. We always utilize both methods to make sure we have the correct figures. Batteries can easily cost similar to what your solar array, so you want to make certain to get it right the first time around!
Solar panel technology has improved dramatically in recent years and the changes made to these newer solar panels allow them to be much more efficient and durable than older panels. These new panels can generate far more power in a given day and will last years longer on your roof as well. These benefits are the result of better formulations used in making the solar cells as well as improvements to the solar panel manufacturing process itself. Even though the basics of how these solar panels for homes work has changed very little over the years, because of these improvements most home solar power systems are a better investment than ever before.
Simple Construction
In simple terms, a solar panel is a collection of individual solar cells that have been connected together inside of a weatherproof enclosure to generate some free electricity from the sun. Even though this sounds like a simple enough arrangement, all of these individual parts need to work together perfectly to provide the best possible output from the system.
Solar Cell Technology
For example, the solar cells used to build one of these solar panels for homes are mostly made from a silicon formulation in the newer panels. The composition of these solar cells has been steadily improved over the years as newer discoveries have been made that allow manufacturers to adjust how these solar cells are made. By adding various chemicals to the silicon base, modern solar cells have become several times more efficient than solar cells produced a decade ago and are also less expensive to produce. They have also become more durable as well and can last far longer than older cells. All of these changes help to make these solar panels a better buy for consumers.
Higher Efficiency Means Small Systems
Since they can generate more power, they enable the average home solar power systems to be smaller and less expensive. This means you'll typically need a smaller investment when using solar power for homes and also have to surrender less roof space to mount the system. The durability improvements are also a great advantage since they allow these newer home solar power systems to last longer and extend the advantages of your initial investment.
Growing Your Solar Cells
The way these solar cells are made involves growing a cylinder of this silicon substrate in a very clean laboratory environment. Once this cylinder is the proper size, very thin sections of the cylinder are sliced off and these become the solar cells. These fragile discs are attached to a non-conductive substrate like glass and small leads are attached for the conduction of the electricity they produce.
Mounting the Cells
A collection of these solar cells are then mounted to a stiff backing board and wired together to form a solar panel. This is all enclosed in a weatherproof casing to protect it from the elements but still allow the sunlight access to the solar cells through a transparent top cover. When this entire enclosure is exposed to sunlight, it can generate quite a bit of power that is then supplied to your home.
Stronger Than Before
In addition to the improvements in solar cell production, newer materials are being used for the construction of the weatherproof enclosure. Materials like aluminum that provides a lightweight and durable frame to mount the solar cells and protect them from the elements has allowed these newer panels to far outlast the older versions. All of these changes help to make these newer solar dc power adapters for sale panels for homes a great investment that the average homeowner can reap the benefits from for years to come.

I was dismayed recently to see an article on the front page of the USA Today on the crisis in the cost in health care. Basically, the article was asking, Who is to blame for the continual upward spiral in health care costs. Is it the doctors, the hospitals, the insurance companies or the individual needing the health care?
I was dismayed because I had just come across a book about a medicineless hospital in that has been effecting miracle cures for nearly two decades without the use of drugs or surgery. Impossible you say? Quite the opposite! The medicineless hospital uses the science of medicine, namely Qigong (chi-kung) which are simple movements to allow the body to regain energy (chi) which leads to abundant health. In this hospital, there are nearly 4,000 - 5,000 practitioners, doctors and patients all working together to allow health to return to the body naturally.
One story about this medicineless hospital relates three chi practitioners sending chi energy to a patient on a table that was suffering from a cancerous tumor on his bladder. Within three minutes (while this was being recorded on ultra sound and video tape) the tumor simply disappeared. That day, the same thing happened with five other patients suffering from tumors. A miracle you say? On only outward appearances, it would certainly seem so. But they were simply doing what millions of others in have learned to do, heal themselves naturally. And it can cost upwards to $70 per month for treatment in this hospital. And it sanctioned by the government.
The thrust of this treatment in this medicineless hospital is self-responsibility. Instead of the patient lying in a hospital bed, the patient is actively involved in the healing process, sometimes doing the qigong exercises for upwards of eight hours a day. Many of these patients came to this hospital with life threatening illnesses only to have them disappear after a month or two. Through simple exercises and a change in their thought patterns their health returned.
After hearing of this, I wondered, why we have this crisis in health care. A day does not go by without hearing of someone afflicted with some form of cancer, diabetes, and a rash of other diseases. I believe, and have for some time, that being responsible for ones own life will allow anyone to take back their power in regard to the care of their health or any other led driver circuit part of their life. When it comes down to it, it is the individuals responsibility as to whether they are healthy or not. But when the individual is responsible for their life, in thought, word and deed, then miracles really can happen.
Some people call this your higher self, your God presence within, your inner CEO, your innate wisdom and a host of other things. The main idea here is that there is a power in the universe that created you and everything else. And when you get this power on your side in creating what you want, it becomes easy and almost effortless. The inner knowing is your connection to this power and is like the non-conscious mind in how it just takes orders and does as it is told. Your inner knowing takes all your orders, just like the non-conscious mind, unless you tell it otherwise.
What this means is every time you have a thought, see a picture, say something to yourself, etc, etc, your inner knowing is listening and following directions. Now stop and think for a moment, how many times a day do you have a thought, say something to yourself or out loud or picture something you don't want? You inner knowing is overwhelmed by all the contradicting messages it is getting. That is why it is so difficult for it to produce results for you.
When you are only having thoughts for the same goal or purpose your inner knowing very clearly knows what to act on and in what direction. This is why when you work at it, train your mind, focus and be conscious you start producing results. Your inner knowing after hours and days of getting told the same thing, with other stuff mixed in, finally gets it. Your inner knowing goes, oh, I guess this is what you really want. Then begins harnessing the powers of the universe to help you fulfill that request.
I am about to share with you an amazing tip that will exponentially speed up the results of everything I have shared with you in the previous lessons. You ready? You can tell your inner knowing what to listen to and what not to listen to. For example: I told my inner knowing that when ever I pause and say "I AM" or "Inner Knowing" - whatever is immediately followed by those words are what I want you to pay attention to until I say "Thank you". All my other thoughts, ideas, pictures, words, etc you can ignore. In this way I do not have to spend months and years training my thoughts to only be solely focused on what I want before I start seeing results.
Action Step: Create your signal to Your Inner knowing (which can be the same as mine) and tell your inner knowing you only want that which immediately follows that signal to be acted upon. Then use this signal to let your inner knowing know what you want help with. When You do this, you will skyrocket your results in any area of your life you ask your inner knowing for help with.
For some this signal is the same thing as praying. If you do it in a 'structured toroidal transformers way' it is creating a signal to your inner knowing (holy spirit) unleashing the unlimited powers of God (the universe) to help give you exactly that. When you start by saying "God" and end with "Amen" it is 'code' to your inner self of what to pay attention to. And when you are conscious of doing this and tell your inner self (God) this is your signal it will produce even greater results.
