  • This is good. Would you know what's happening in India vis-a-vis solar power?

  • In India it is mandatory to have solar water heaters on new building complexes. Not much is going on the solar side from my friends in India.

  • Any chance you might post a schematic/wiring diagram?

  • Where are you based.

  • Where did you get the hardware. How much voltage are you getting. Steam? Did you build it or was it a kit. Thanks for the great video. So many questions:-) Awesome. It looks like it is lined with a 75% mirror. Do a video at dusk to show the surface, camera will handle light better.

  • The hardware is a Standard Satellite Dish. The arms have to modified. This dish to track the sun path using the actuators.Actuators are also the standard one to motorise a dish

    The heat exchanger was machined by my associate. He has a machine shop so he welded and machined the heat exchanger.

    The Dish raises the temperature 3 gallons of water by 30 degrees Fahrenhiet in approximately 1 minute on a sunny day.

  • Very nice. I'm working on one myself right now. Just mounted the second actuator. Next will be putting the tracker, motor driver circuits and stuff together. Hope to upload a demo in a few months.

    I'm curious what material / process did you use for the reflective coating?

  • The sensor is used to track the sun . The circuit gets a signal from the sensor and drives the actuators. The circuit has enough power to power the 12 V actuators.

    The sensor determines the position of the sun which drives the actuators to focus on the dish

  • Very cool!

    Can you tell me how you powered your linear actuators? Do you have a microcontroller in line somewhere? Also, are you using an optical solar follower or other input to track the sun?
