How can I make a solar powered water purification system?

We Answered:

Over in Africa they are using plastic bottles laid out in the sun for a few days to purify water. It's low tech but it works. You can read about it in the article below. And it can be done with simple household items.

Run a 1200 watt microwave on an 800 watt solar power system?

We Answered:

The 800 watt spec on the solar panels and charge controller is how much they can push into the battery pack at full output. These won't be affected by the load of the devices that use electricity.

In order to run the microwave, you need to be sure that your inverter can handle it. A 1200 watt inverter would strain to run a 1200 watt microwave because you don't want to load up your inverter to 100% if you can avoid it and there would likely be other electric devices turned on at the same time.

Another thing you need to be sure of is that your battery pack can deliver 1200 watts plus whatever overhead is needed to make up for inefficiencies in the electrical system. This probably is not going to be an issue, but you need to be aware of it.

Also, I suggest getting a lower wattage microwave. I have two microwaves (5 people in the family) and one is 950 watts and the other is 600 watts. I use the 600 watt unit most of the time because the 950 tends to incinerate things really easy. By running a lower wattage microwave you will also save some cost in your electrical design as well as prolong the battery charge levels when you aren't getting as much sunlight. Same goes for your hair dryer and toaster.

Solar powered adsorption refrigeration system. ( Silica gel as refrigerant)?

We Answered:

The system works on endothermic hydration of the refrigerant,
with solar heat used to re-dry it.
What's the heat of hydration of your gel, and how do you
intend to move it through the cycle?
