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. Some have already tried and ended
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

Nice, thick & comfy but came w/ punctures in foam; seller provided discount
Color: Purple, Color: Purple
I love the mat. It's thick and very comfortable on my knees. However, when I opened it for the first time at my yoga class, there were several cuts or punctures in the foam. I attempted to return it and the seller offered me a 10% refund due to the damage. I am concerned that the mat may deteriorate due to the damage it came with, but I need it and have no idea if the cuts will matter over time. So I accepted the $3 refund and am keeping the mat.

Best mat purchase yet
Color: Pink
I love this mat. I wish they had it in larger sizes. The only one I have truly non slip. Extremely comfortable especially on my back. Great price.

Great workout mat
Color: Green
It’s very thick and soft so it makes exercising a lot easier. It rolls easily ready to store. And it seems very durable. It is also flexible for certain exercises for balance.

Very sturdy. Great Quality
Color: Navy Blue
This is a very dense, thick mat. It's great if you have bad knees or just need/want a thicker mat. The carrying strap with velcro closures is easy to use.

Great cushioning, easy storage
Color: Blue
I am so happy I bought this. I do back stretches, and need to be on the floor.. Getting up & down is hard at 77, and carpets are hard. This helps sooo much! I don’t hurt my knees when getting down or getting up. The mat is comfortable and provides plenty of padding. It is easy to roll up and store with the included strap. I am tall, and there is extra length, so my head and feet are on the mat. This was a good purchase! This has not torn, and wipes down easily. It doesn’t attract dog hair, which is another reason I wanted a mat.
