Kyocera KD135GX-LP 135W 12V Solar Panel - $550 + $25 S&H. Kyocera's advanced cell processing technology and automated production facilities have produced a multi-crystal solar cell with an efficiency of over 16%. All Kyocera solar panels are constructed using a tempered glass front, EVA pottant and a PVF backing to provide maximum protection from the most severe environmental conditions. The entire laminate is framed in a heavy duty anodized aluminum frame to provide structural strength and ease of installation. Because Kyocera solar modules are so efficient less space is required than other solar panels of equal output. This translates to both more wattage per square foot and lower mounting structure cost. |

We have a shallow well, 25', that we dug ourselves. We also harvest rain water. We needed a reliable, inexpensive way to purify our water. The Berkey water purifiers have a reputation that spans 100 years of providing pure drinking water from foul sources. In our case, our water registered high levels of pesticides and fertilizers, and E. coli. Now it registers well within safe drinking standards. If you live where your water source isn't safe or is suspect, or you cannot guarantee it's purity in times to come, you should investigate this unit. We have, and we are happy. The Berkey Light is clear plastic, the other Berkey's are Stainless Steel. All come with 2 filter cartridges good for 3000 gallons each. |

The DIY Berkey Water Purifier
This unit uses the same Black Berkey Purification Elements the commercial purifier uses, but instead of the stainless steel construction, it has re-used food grade 4.5 gallon buckets. The ultimate in recycling and low embodied energy, and for a big savings. $150 |

Welcome! to Nature's Head Composting Toilets. This is the latest design in portable, self contained, urine separating dry toilets.
This toilet or head, (the marine term for toilet) was designed by two long time sailors who sought to create a more user friendly version than anything else on the market. While we designed our product to withstand the harsh marine environment, it can be used anywhere you need a toilet, especially anywhere that plumbing or electricity is difficult or non-existent. Most importantly, our toilet doesn't have the foul odors associated with all other holding tank systems.
The low volume air circulation fan built into the head provides the added benefit of recycling the air in your bathroom which helps make your whole environment smell better. Because we designed our product for the marine environment (all stainless parts and hardware) it should prove to be extremely durable no matter what environment you use it in.
Other uses could include cabins, cabanas, boat houses, hunting camps, RVs, basements, semi-trucks, and even pick-up trucks. $900, delivered, lower 48 states. |

A lot of folks have been buying the $199 Harbor Freight 45 watt Solar kits. We have 4 of the kits, and although the panels are ok, the charge controller that comes with them is severely deficient. We are providing an excellent replacement for the included controller. It's a Sunguard SG-4, 4.5 amp PWM controller. We also have the Sunsaver 10 and 20 amp controllers for multiple sets. We discuss these at 12vdc Power.

People who haven't read and applied the information in the two books, Living on 12 Volts with Ample Power, and Wiring 12 Volts for Ample Power have wasted millions of dollars. Purchasing the wrong batteries, or charging good batteries improperly are two expensive mistakes which can be avoided. Other costly mistakes include buying instruments which don't have the accuracy and resolution to be trusted, or buying multi-step regulators which taper charge Amps the same as standard automotive regulators. If you're going to pay a premium for a speciality regulator it should charge fast and full.
The Ample Power CD contains both books, the Ample Power Primer, installation and operation manuals, and product data sheets. Also included are articles from Power News and the FAQ. All the files are formatted in the popular PDF format for easy offline reading and searching. $35, delivered, lower 48 states. More info can be found at 12vdc Power.
