Anguilla Solar

We just got back from our trip to Anguilla. We helped Francoise set up her new solar power system. Two Kyocera 130 watt PV panels, a Xantrex C35 charge controller, a Trimetric Battery Meter, a Morningstar Microsine 300 sine wave inverter, and a 70 ah AGM battery, power up 3 Compact Fluorescent Lights, A LG WP-680N Washing Machine (260 Watts) and a Shurflo 12v pump. Two weeks of testing, and we were never able to pull the battery below 12.4 volts. The system consistently output 1.5 kWh’s daily. More pics at http://www.green-trust.org/Anguilla Solar/.

All About Batteries

Off grid homes, RV’s, and boats use a house bank, a bank of batteries used to store the energy from solar, wind, and backup generators for times of no sun or no wind. These are not car batteries, these are specially designed deep cycle batteries that can handle repeated deep discharge and charge cycles.

Watermotor - Simple Mechanical Drive

Most of the common machines used in workshops, industry, and farms are driven by motors of only .5 - 5 horsepower. The Watermotor will produce this amount of power at an extremely low cost and with a minimum of ecological disruption.

High energy efficiency means that the quantity of water necessary for operation and cost of installation is greatly reduced, while on the other hand the number of actual locations where waterpower on this scale is available increases exponentially. In effect, every small fast-flowing stream becomes an important local energy resource, perhaps in many cases the only practical one available. In the world’s hilly and mountainous areas there are often few roads and even fewer electric power-lines. While frequently rich in small scale water-power resources, the people are poor.

The Watermotor is a practical means of utilizing one of the easiest to use and most efficient sources of natural energy.

How much energy does a product use?

When we buy electrical devices, or we need to test one we have, we use a special meter called a watt-hour meter to see how much energy a unit uses over time. The meter we have is called a Kill-A-Watt, and it reports volts, amps, watts, watt-hours, power factor, frequency (important for tuning a generator), and time. Approximately $30, this is one tool no conserving household shoule be without. Take it when shopping for appliances for comparing energy consumption.
