Solar Tracker Arduino Project
Overview: This device keeps a flat panel holding a solar cell continuously following the sun as it moves across the sky. The Arduino uses 2 light dependent resistors (LDRs) that are separated by a fin to compare the light levels on either side and then rotate the servo attached to the panel towards the more illuminated LDR until the two detectors are equal. This is a nice Arduino project which combines sensors with servos, with logic that can be tuned, and has a practical application relating to clean energy. Background: Solar panels generate the most electricity when the incoming light is perpendicular to the panel. A...
Modeling Solar Grid Integration with Math
Overview The purpose of this lesson is to introduce the students to the challenges of integrating solar energy to the electricity grid with the use of numerical simulations. More specifically, it is meant to shed light on the advantages (mentioned in the introduction of this document) and on the challenges (challenges 1 and 2 from the introduction) of solar energy. Solar Integration Lesson Essential Question: How can we optimize energy prices by controlling load and production? NGSS Standards: Standard Number Standard text HS-ETS-1 Analyze a major global challenge to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants. HS-ETS-2 Design a solution to a complex real-world problem by...
