Overview
Research pertaining to the Solar Concentrator.
Research
- Google.org
- Wikipedia: Maximum Power Point Tracking
- build it solar projects
- Arduino Heliostat / solar tracking
http://openframeworks.cc could have some useful code and application to this. It would probably only use one of these systems displayed. Also generally an amazing resource for realtime 3d, robotics, arduino control.
Technical Requirements
Open Source Ecologie team (OSE French chapter) is researching and developping the linear fresnel reflector. the team want to hear from you on the set of requirements you would expect as output from the solar concentrator of this kind. the current work in progress is located [| here]
you can see 2 columns describing the level required at the 2 different phases of the project, for each requirement we expressed the rate of achievement required.
Phase 1 - Demonstrateur : is the proof of concept that will be presented in the "[| Villages des alternatives]" in Paris the September 26th 2015 of 4m^2 of mirrors. Phase 2 - Prototype a: is the full scale product that we expect to deliver early 2016 after a crowdfunding campaign launched during the Villages des alternatives. This will be the Alpha prototype.
The French ethercalc version of this work-in-progress product specification requirement is located [| here]
this document is part of the Product Document Requirement
Introduction
Added to this list of specific requirements, the general [| OSE Specification for product design ] should be also applied during the conception and design.
After conception and design are completed, a score will be attributed based on the [[ http://opensourceecology.org/wiki/OSE_Specifications_Assessment_Template | Ose Specifications evaluation Template]] and its adherence to the below set of requirements.
the discussions can be carried out on the [open forum]
