How To Build A Solar USB Charger

This document helps you build a system to charge mobile devices via USB with energy from a solar panel. It includes a large section on how to use the RETScreen tool to analyze your power needs and turn those into battery and panel requirements. The plans were created by the Fall 2017 class of the Nova Scotia Community College Introduction to Renewable Energy program.

Small Scale Solar For A Woods Camp

By Carolyn van GurpBattery box

Until two weeks ago, my mainland Nova Scotia 8 X 16 woods camp had been powered primarily by candle, making for long winter evenings.

With the guidance of a patient solar-powered neighbour and after finding a 40 watt solar panel on sale at Canadian Tire, I decided to take the plunge and upgrade.

Intro to Site-ing on North-Facing Slopes

All sites are not created equal. While the full benefits of passive solar can only be gained with an unobstructed southern exposure, many sites offer less. Of course, solar is only one consideration, and not necessarily the most important. To get the most out of it, you will have to plan your site.

2014 Solar Nova Scotia Revitilization Report

In 2014, several Saint Mary's University Business students did a study on the needs of Solar Nova Scotia members and potential members.

This objective was addressed by gathering, consolidating and presenting input from members and interested parties, then gathering ideas and gaining commitments to action. These were achieved by using a digital survey followed by an in person presentation and workshop.

Bonding and Grounding of Photovoltaics

By Jeff Harrop

Ground is the earth and where voltages over 50 volts must be referenced from. This includes DC (Direct Current) and AC (alternating current) voltages. In order to do this we have a connection to the earth for each power system installed on a premise. It can be a set of driven rods, a plate, the copper water piping system, or a well casing.

The photovoltaic panels have lethal potential voltages and therefore must be bonded to the grounding system to protect people from live voltages from energizing the metal framework of the panels.

All About Inverters An inverter is just a DC to AC converter. Why do we have them in solar applications? Solar PV (photovoltaic panels produce DC (direct current) electrical energy. In our homes and businesses we use electrical devices that take their energy from an AC (alternating current) source.

OK, the time has come to debunk this. People are going to die. They will be cold, asphyxiated or burned to death.
