Alternative Power

Both monocrystalline and polycrystalline solar panels can be good choices for your home, but there are key differences between the two types of technology that you should understand before making your final solar purchase decision. The main difference between the two technologies is the type of silicon solar cell they use: monocrystalline solar panels have solar cells made from a single crystal of silicon, while polycrystalline solar panels have solar cells made from many silicon fragments melted together.

Monocrystalline Solar Panels

Monocrystalline solar panels are generally thought of as a premium solar product. The main advantages of moncrystalline panels are higher efficiencies and sleeker aesthetics.

To make solar cells for monocrystalline solar panels, silicon is formed into bars and cut into wafers. These types of panels are called “monocrystalline” to indicate that the silicon used is single-crystal silicon. Because the cell is composed of a single crystal, the electrons that generate a flow of electricity have more room to move. As a result, monocrystalline panels are more efficient than their polycrystalline counterparts.

Polycrystalline Solar Panels

Polycrystalline solar panels generally have lower efficiencies than monocrystalline options, but their advantage is a lower price point. In addition, polycrystalline solar panels tend to have a blue hue instead of the black hue of monocrystalline panels.

Polycrystalline solar panels are also made from silicon. However, instead of using a single crystal of silicon, manufacturers melt many fragments of silicon together to form the wafers for the panel. Polycrystalline solar panels are also referred to as “multi-crystalline,” or many-crystal silicon. Because there are many crystals in each cell, there is to less freedom for the electrons to move. As a result, polycrystalline solar panels have lower efficiency ratings than monocrystalline panels.

Both types of power inverters will provide power to AC appliances. However Pure Sine Wave is a higher quality, equal to (or better than) the power in your home, A modified sine wave power inverter is a much simpler form of power and is adequate for simple electronics, but may damage more complex electronic devices like computers and cell phones. As a result, a pure sine wave power inverter will always be more expensive than a comparable modified sine wave inverter with the same wattage specifications.

Emergency Supplies

All three are totally different and it is important to know the differences as shown below.

  • An antibacterial is anything applied to the skin that's active against bacteria to slow down or halt bacteria. Simply, antibacterials are agents directed against bacteria.
  • An antiseptic is applied to the skin to deter microorganisms, including bacteria, fungi, protozoa, and viruses, so it's stronger than an antibacterial.
  • A disinfectant kills bacteria, and also viruses and fungi, but it applies to other surfaces (and not living tissue, like skin).

Food and Water

You need water to sustain life for you and your family. But, the quality of that water is just as important as the quantity available to you. Whether your family relies on a municipal water system, a private well or even bottled water, you cannot be sure that it is safe and free of toxins and bacteria. Filtering your drinking and cooking water is critical to safeguarding your family’s health.

With the so many aesthetic, organic, inorganic and microbiological contaminants threatening your water supply, filtering it before use makes eminent sense. If you don’t, you cannot be sure that the water you and your family consume on a daily basis is safe, clean and life sustaining. 

If you are part of the 14 percent of Americans who source their drinking water from private wells, you may believe your supply is naturally pure. The fact is, however, that unless you test your well water regularly, you could be drinking more than you bargained for. Unlike community water supplies, government does not regulate well water quality. Because you source your water from underground, it may contain heavy metals like lead and mercury, or other toxic minerals from natural deposits. It could also be contaminated with pesticide residue, nitrates from fertilizer runoff or even bacteria from organic waste, mercury, or other toxic minerals from natural deposits. It could also be contaminated with pesticide residue, nitrates from fertilizer runoff or even bacteria from organic waste.

No - NEVER reuse disposable water, juice, milk and soda bottles. Most disposable water, soda and juice bottles have polyethylene terephthalate, also known as PET or PETE. While these bottles are safe for one-time use, they may leak DEHP (a carcinogen) when used repeatedly. So only store these items in new containers designed for long-ter storage.

While it can be tempting to try and pack a lot of water, it’s usually one of the heaviest items in your backpack or survival kit. Cut back on it as much as possible and plan on including around 1 liter per person every day. Make sure and include NaDCC-based water purification tablets in your kit or backpack.

Knives, Blades and Tools

Preppers dig with both spades and shovels, and often us the terms interchangeably. The correct and key difference between a shovel and a spade is primarily the scooping tip.

  • Shovel - has a concave shape and usually a pointed tip is good for digging camp kitchens, graves, trenches, and for shoveling snow. Shovels help you dig. The telltale sign that you have a shovel is if it has a concave scoop. It's good for lifting and throwing material. Think of a shovel as the way to load and unload sand, soil or gravel from a wheelbarrow.
  • Spade - has a flat edge and is often rectangular, is ideal for digging fire pits or trenching around tents. It's confusing because the spade on the deck of cards has a pointed tip. The D-handled spades are best for work on trenches! The straight, flat edge is good for cutting, loosening and leveling soil. Typically, a spade is narrower and flatter than a shovel. While you can certainly use a spade for digging, they are intended for slicing through and lifting sod. Here's how to use a spade.

Sometimes you will need to use both. Grave diggers use first a spade to outline the area, then a shovel to load and unload the dirt if done by hand.

Survival Kits

Well, you know what is most likely to occur in your general area - earthquake, hurricane, tornado, economic collapse, power grid failure, zombie apocolypse, etc. You should build the bag for whatever you think is most likely to happen. It is not a bad thing to have more than one. At a minimum, one for general purposes for 2 ro 4 people would be needed -like you can find here.
