Portable PV Power – 800WP System

We were asked, by a good friend from Wild Stoves, to produce a portable solar PV off-grid power supply system. Wild stoves supply equipment for efficient outdoor cooking on wood. They run workshops on efficient burning of wood and sell equipment at a number of festivals over the summer. We had been asked to add … more

PV I-V Curve Tracer

It is very useful to measure the current against voltage characteristic for a solar photovoltaic panel. Here I shown how I built an I (current) against V(voltage) curve tracer for solar photovotlaic panels which is battery powered and can be used ‘in the field’. The output is displayed on a full colour LCD display, along … more

Solar car kits

Re-innovation were behind the original solar car kits used by reaction education. They supply renewable energy and engineering activities for a wide range of educational events. Their main activity is to design, build and race a model solar powered car. The kit includes a number of solar panels, motors, wheels and gears along with a … more

DIY solar PV panel information

Here are collected notes and ideas on building your own solar photovoltaic (PV) panel. These come from a number of places including attending a course run by Dan Quiggin of Demand Energy Equality, web-searching, discussion with Norman Phipps of Handmade Solar and also running my own DIY PV workshop at Nottingham hackspace. I feel that … more

Overview

Solar PV lanterns

A report written for Digital Campus which reviews a number of solar PV lanterns with a view to deployment in Ethiopia. This report was written to look at using solar PV lanterns to recharge smart mobile phones in remote locations. … more

Solar PV design worksheet

This is a simple design worksheet for stand-alone solar PV systems. It explains the design process and explains some of the practicalities of building a system. This document is open source. … more

DIY solar PV system

Here are some details on the prototype for the ‘build your own’ solar power system I ran as a workshop at the Nottingham hackspace. I’m pretty pleased with how it looks. Basically it is a micro solar PV (photovoltaic) system, which includes a 10Wp solar panel, charge regulator and voltmeter, all encased in a laser … more

Caravan solar PV system

A friend has been using a beautiful 50’s caravan to head to festivals and sell efficient outdoor cooking apparatus, through his company wildstoves.co.uk. He had already installed a 12V lighting system and a deep cycle battery. This year he planned on expanding his system and incorporating solar PV power. Already a very low user of … more

Solar powered laptop

During 2007 this simple solar photovoltaic (PV) system has provided some of my energy needs (OK, a pretty small percentage I’ll admit). In total there are approximately 40W(peak) of PV panels. … more

Beach hut solar PV system

Renewable Energy Innovation designed, installed and commissioned a small solar PV array for a beach hut in Mudeford, Nr Christchurch on the South coast of England. The hut is owned by the Timms family who wanted to power a fridge, lights and some small appliances (mobile phone chargers etc.) throughout the main season (from mid … more
