Connecting to the Grid: A Letter from Paul
Dear potential grid connected customer, Many people contact us concerning the possibility of using a power source that is either connected to the commercial power grid or feeding power to a house that is. While this may be possible, it is not ...

Water Rights: A Microhydro Evolution
Every morning, before brushing teeth or having a look at the weather outside our Victoria, Australia, off-grid home, my wife Carrie or I pad downstairs to the battery room to check the meters that monitor our electrical system.

Microhydro-Electric Systems Simplified
If you have a suitable site, harnessing the energy in a stream or creek can be the most cost-effective way to make renewable electricity. Compared to the sun and wind’s variability, a stream’s flow is relatively consistent, making ...
-
Micro Power to the People
A letter to the editor alerted me to my chance to finally see a microhydro system. On January 18, Vivian Stockman and I visited Mickey and Jennifer Janowski, who live at an elevation of 2,250 feet in Webster County, W.Va. ...

Intro to Hydropower - Measuring Head and Flow
Small-scale hydro is the only renewable energy source that works for you 24 hours a day, 7 days a week. In the first article in this series (HP103), I explained the basics of hydroelectric system theory, and reviewed system components. This article ...

Managing Battery Charging - Using Diversion Loads
Tcharge regulation can be relatively simple: When the I-`1/batteries are full, the controller disconnects the PV r array. Adding wind or microhydro to the system makes charge regulation more complicated, since turbines may overspecd if unloaded. ...

Water Line Project - Holloway Bar Placer Mine (archived)
One of the biggest problems with living in a remote area is access to facilities that we take for granted. If you want to watch TV, you need both a satellite dish and power to run the dish and TV. If you want to have a shower, you`ll ...

Grid Connection An open letter to those on grid considering pursuing hydro power
Many people contact us concerning the possibility of using a power source that is either connected to the commercial power grid or feeding power to a house that is. While this may be possible, it is not likely to make economic sense. Over 99% of our ...
