How Much Power Does Your (eg) 250 watt Solar Panel Actually Produce?

So there you are, thinking about buying some solar panels.  You’ve noticed they come in a range of semi-standard shapes and sizes, and maybe you’ve even noticed that the slightly unusual dimensions (such as 39.4″) actually make sense if converted to metrics (ie 39.4″ = 1 meter). You also notice all sorts of acronyms floating around in the specifications and warranties, and you sort of wonder if, when comparing the power output of Brand X’s […]

Free Solar Energy Spreadsheet/Calculator

One of the most important things for you to get right is balancing your retreat’s energy requirements with its energy production and storage. These three variables – how much energy you use, how much you produce, and how much you store – are all dependent on each other, in a complex series of interlinked relationships, and all you really know for sure is that you never want to run out! But trying to match together […]

Designing Your Roof for Best Solar Panel Use

This is a further part of our series on solar energy.  Please also visit our sections on energy in general and solar energy in particular for more related articles. What makes a roof better or less suited for having solar panels mounted on it?  How should you design a new retreat structure, and/or, if looking at buying an existing dwelling, how do you know if it is optimized for solar? Answering these questions is reasonably […]

Fuel Cells and Hydrogen for Preppers

This is a further part of our series on solar energy.  Please also visit our sections on energy in general and solar energy in particular for more related articles. Chances are you’ve not even thought about hydrogen powered fuel cells as part of your retreat energy strategies.  For most purposes, fuel cells would indeed not be a good choice, but there’s one special scenario where they might be of relevance – as part of a […]

How Much Extra Emergency/Reserve Capacity Does Your Solar Power System Need?

This is a further part of our series on solar energy.  Please also visit our sections on energy in general and solar energy in particular for more related articles. There are two ways of developing a solar system for a retreat.  By far the simpler is to simply go out and buy the biggest bestest system you can afford, and whatever you end up getting is what you have, and you’ll adjust and survive as […]

How Much Solar Power Generating Capacity Do You Need?

This is a further part of our series on solar energy.  Please also visit our sections on energy in general and solar energy in particular for more related articles. We’ve already written an article pointing out something you hopefully already know – solar power is a wonderful energy source for preppers.  If you don’t already have some solar power on tap at your retreat, you should urgently add some. But – how much solar power […]

Air Conditioning and Solar Power

One of the basic principles of planning a retreat is to minimize your energy needs, and a key part of that is the design of the retreat so as to make it as well insulated as possible.  This will cut down on your heating energy requirements in the colder months, and should also cut down on your cooling energy requirements in the warmer months. Well, that’s the theory of it, anyway.  The reality is a […]

Why Solar Energy is So Wonderful for Preppers

This is the first part of a series on solar energy.  Please visit our sections on energy in general and solar energy in particular for more related articles. Every part of our world is defined – and/or constrained – by energy.  Our modern civilization – something you might think of as being all about computers and the internet, or perhaps all about big cities and high-rise buildings, or perhaps jet planes and satellites – has […]
