Many of the folks who visit our site are interested in installing a solar or wind electric system for their home but they do not know where to begin. Although to a certain degree each situation is different there are a few basic things that we will need to know to get you started.
The answer has a lot to do with understanding your site's potential for insolation, wind, and water flow.
Before beginning your renewable energy journey, read this guide on the five most important tips to consider.
Yes, but there's a much better way...
Voltage-schmoltage! Read more about the four main voltages used in RE systems.
Basic schematics with examples of series and parallel connections for batteries.
Short answer: It depends on the size of the system and what type of loads you want to run...
Quickly find the the typical power rating (in Watts) of many common household appliances. Use this information to help estimate how large your alternative energy system needs to be.
Determine the maximum amount of electrical current (amps) that can safely flow through different wire gauges.
All inverters convert direct current (DC) electricity into alternating current (AC) electricity, but that's where the similarities end between inverters. These days, a huge number of brands and options are available to consumers, and the correct choice for you depends on how you intend to use it.
