Build Your Own Low-Budget Solar Power SystemThis book is designed to address the concerns of those whose only desire is to build a simple, small scale solar energy system but don't know where to start (or end!). We've been living off the grid for well over ten years now and the most common inquiry we get is from people who want to set up a small solar energy system to power a cabin or camper, or to keep a refrigerator and a few lights on if the grid goes down.

This book is designed to address the concerns of those whose only desire is to build a simple, small-scale solar energy system but don't know where to start (or end!). We've been living off the grid for well over ten years now and the most common inquiry we get is from people who want to set up a small solar energy system to power a cabin or camper, or to keep a refrigerator and a few lights on if the grid goes down. Some have already tried and ended up with woefully inadequate systems lacking the power and balance needed for off-grid life. But there's more to off-grid living than watts, volts and amps. It's important to understand how a solar power system works and how to size it properly for the job you want it to do. In this book I've condensed all the information you need to design your own simple, off-grid, solar power system. I'm not going to teach how to build your own solar panels but I'll tell you how purchase factory components to build the system that fits your needs the best and hopefully save you a lot of frustration and cash while putting it together. We'll see how to understand watts, volts, amps, and ohms and how they apply to deciding how many solar panels you need, the watt ratings you'll have to have for your inverter and charge controller and even how many batteries you'll need for your battery bank. You'll learn about resistance, and how it affects your solar power system. I will explain with diagrams and text the differences between sine wave, modified sine wave and pure sine wave inverters and how that applies to you. I'll explain charge controllers and the reasons for and against PWM vs. MPPT vs. single-stage vs. multiple-stage controllers and which is best for you. I'll tell you a little secret about "efficient" vs. "less efficient" solar panels that will keep you from wasting money on something that's a relatively minor issue. Even if you don't want a "whole house" system you'll learn how to put together balanced small-scale power systems at whatever size you can afford. We'll also look at solar power "kits" and I'll show you how to put together your own that outperform commercially available kits and get more power for less money. My goal here is to simplify that which has been made complicated. I want you to be able to pursue your dream of independence from the grid without spending enough money to break the bank. It can be done, and for less than you may imagine!Shipping Notes

Lemon: Very weak, almost undetectable
Scent: Lemon
I’m not impressed. I ordered the “Lemon” and it’s nothing like the “Aloe & Green” Tea we had at work. Unfortunately Amazon mixes the reviews together, so you can’t tell which scent actually got the good reviews. I can barely smell the lemon and I have to try really hard. And I’m someone who prefers soft scents that are not overpowering, because I have a sensitive nose. I can’t deal with strong perfumey stuff. But I would like to at least smell something. I remember the Aloe & Green Tea has a nice soft scent, that I could actually smell. So I’m not sure what’s going on with the lemon, unless I got a dud. I’m having a hard time believing this is how it normally is. I’m going to get some opinions from my guests and see if they can smell it.

Such a fresh clean scent
Scent: Ocean Breeze
Such a clean fresh scent
Doesn't have all the toxic chemicals in most room sprays. I have been using this for years. One spray freshens the room.

Nice product
Scent: Lavender
I love this light fragrance that’s not overwhelming and doesn’t leave any kind of sticky residue or film. I buy often.

Great for sensitive skin, cleans well.
Scent: Unscented, Size: 4 Ounce (Pack of 2)
Only soap I can use at the moment. I have extremely sensitive skin: I cannot do really any coconut derivatives or even palm oils but this soap does not bother me at all. I feel clean with no heavy scents afterwards (I use the unscented version) which is a win in my book. I don’t use it on my face or hair just as a body soap and it doesn’t make my skin feel prickly or give me any unexpected rashes/reactions. It is a little drying for eczema prone skin so I just use more lotion when necessary. You get two very large bars that last well for the price it seems reasonable, but honestly I’d pay anything to not itch at this point.

You will not regret buying!!
Scent: Unscented, Size: 4 Ounce (Pack of 2)
I don't normally write product reviews but this soap truly deserves it. I had heard about beef tallow products as a carnivore dieter but hadn't paid too much attention to them until I found a huge mass on my thyroid. Suddenly, I'm looking at all the products that I use and am shocked that everything has endocrine disrupters like dyes and fragrances. This was the most natural soap I could find and what a huge turn around in my skin. I have always had certain areas that are habitually dry and even lotion would not 100% fix them. After using this soap for over 2 weeks, my skin is so smooth and almost has that glow you see in lotion commercials. I have not applied any lotion at all in the last 2 weeks and I'm softer than I have ever been. I even shaved with it and it was the smoothest shave I have ever had. I used to use conditioner to shave with and this soap is far superior. It is also far superior to the facial lotion soap I was using. My face isn't dry anymore and no more rebound oil. The people that I have told about this are immediately grossed out and think that the soap smells. There is an ever so slight hint of tallow but it does not last and once you start using the bar it isn't noticeable unless you sniff the bar itself. It does initially leave that sticky feeling that you get from Castille soap, which is strange when you're used to conventional beauty bars or body washes. But please don't quit using it! That sticky feeling is adding moisture and protection to your skin and once you towel off I promise you will not feel sticky. After a few weeks, I promise it won't feel weird anymore and you'll have the best skin of your life!! I'm sorry for the long review, but I am so grateful for this product. It is not only a beauty miracle but better for your whole body, no more toxic chemicals leaching through you skin.
And people are not lying when they say this soap lasts. I use it twice a day and I still have a good sized bar left. Also, it really does not disintegrate like regular bar soaps. A few reviews mentioned it being expensive and my husband also commented on this when I bought it, but in my opinion it is extremely cost effective!! This is my rationale, it replaces the facial lotion wash, shaving conditioner, and the need for body lotion and it lasts a long time. My other reasoning is that the long term medical costs of using toxic products just doesn't seem worth it.
