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.
OSE Technical Requirements
as Open Source Ecologie team (OSE French chapter) is moving forward developping the linear fresnel reflector is developing and request for your participation the complete set of technical requirements. the current work in progress is located here
| Module breakdown for solar concentrator and its prove of concept. | ||||||||
| Added to OSE Specification for product design and more specific | http://opensourceecology.org/wiki/OSE_Specifications_for_Product_Design | |||||||
| A score will be attributed on the designes based on the Ose Spe | http://opensourceecology.org/wiki/OSE_Specifications_Assessment_Template | |||||||
| Prototype | Proof of concept / Demonstrateur | |||||||
