Small Steps to Solar Independence

Designers Edge L-949 10 LED Rechargeable Solar Panel Shed Light Model

 Not everyone can afford to go for the full off grid system right out of the gate but that shouldn't stop you from starting somewhere. I am a really happy to see smaller stand alone devices coming into vogue on the market recently. The technology isn't going to stop the world but at least its a start. I stumbled across this little gizmo here today and thought I would share. 

 It's a self contained solar light that has an extension cord to get the panel out into the sunlight to charge the 3 on board triple A batteries. I have seen several outdoor lights available listed as security, or spot lights but they mostly have the solar panel attached to the housing of the lamp itself. Where this one lets you get the panel out into the light with its 20 ft line so you can light up the dark little nooks and crannies during the day as well as at night. 

 The ease of installation permits even the less electrically informed among us to take advantage of free power without the hassle of playing with car batteries and solar controller and all that jazz. 

 The drawback to a system this small is a short life. It is only expected to produce light from all its 10 leds for 2 hours, and there is a low switch that lets you run it at half power for 4 hours (5 leds). If you want to just go out into the shed to grab a few things than 2 hours will be more than enough but if you  need to be out there for a little while than you may find it advantageous to get 2 sets that way you can produce up to 8 hours of light, in case your needs would so demand. 

 I think this will be a fantastic little setup if you need to get some candle power going in a dark spot without a candle or and electrician. This is probably the next best thing to a set I brought to your attention earlier in my article First Solar,Amorphous panels  . And its surely an easier way to get you on the road to your first solar experience.

Then you can pick up something like this florescent 12v light that will provide an amazing amount of light for its size and power consumption. These can be easily wired up to a standard lamp socket (like the ones in your house) then you just supply the 12v current and you are in business. Of course you can use the above mentioned amorphous panel set's 200 watt inverter to run any old household lamp as well.(albeit a bit less efficiently)

 Just be sure you don't get your 12v Dc (battery power, and solar panel power) and your 120v Ac (inverter power) confused.

What Is Amorphious, First Solar panel

  What is amorphous, in Latin it is spelled "amorphus". If you asked a Greek speaker "What is amorphous?" They would tell you it is spelled amorphous which is where we get the spelling in English.

 It's definition is; "having no determinate shape or structure, shapeless, unorganized."

 If you asked a chemist "What is amorphous?" They would tell you "Its of a solid: not crystalline, or not apparently so."

 Amorphous solar panels are usually marketed as "thin film Pv panels". They are constructed from a vaporized silicon and applied in an amorphous form or (a-Si). Amorphous  silicon being without apparent structure or shape is without the crystalline structure of conventional silicon Pv cells. Due to the non-crystalline composition it is flexible in nature, so when it is applied to a flexible surface it can form a panel with the same overall properties (flexible). A-Si can be applied at a low overall temperature so plastic can withstand the process and due to its flexible nature you can use it as a base for flexible applications. There are other materials used for thin film pv panels but this is the amorphous variety.

   If you want to try your hand at your first solar panel to produce electricity, it may be wise to start small. If you get the principles down with a small amorphous solar panel set (PV) than you will know better what to do with a full blown off-the-grid solar panel array to fuel all your electricity needs.

  The main thing to remember is not to run appliances that require more power than your first solar panel can handle.  As a rough rule of thumb...
