I'm trying to design a solar powered garden watering system for my parents, whom live in the desert. I have two possible options:
1. Use a primary water heating system, where a water tank is heated by the sun and the water is condensed, and then drains (via gravity) onto the plants.
-problems.. The water will only flow during 75% of the year, the water has to be replaced with an electric pump, and I have no clue what dimensions\materials will be required for the base water tank.
2. A secondary solar heating system, where solar cells power batteries that then drive a heating system and a refill pump.
-problems... I don't have any clue how many watts are going to be required from the solar cells in order to keep the whole system running, and I don't know what type of heating unit to use in order to turn the water into vapor.
So I was wondering what system I should go with? Plus, can you elaborate on why one is better\cheaper than the others.
Hardy har har. Very funny. But there isn't much rain in the DESERT!
