The wife of mine and I have lived in an all sun house for twenty years. We heat, power and now cool our home with the sunshine. Residing in a solar building requires us to to think conservatively when using electricity. Keeping the home cool of ours in the summer was an issue to start with since our solar electrical charging system couldn't provide enough energy to power a standard air conditioner.
In a home which we used to exist in we used an evaporative cooler to cool the home of ours. They work nicely in dry climates and use about 1/4 to 1/3 the potential of conventional devices. As we live in essentially dry climate, I believed that I could be in a position to make use of the same kind of cooler in our home.

I initially purchased several units that had been used inside the house. They had some area to add water but they weren't really effective since they didn't pull in outside air which is the best way of cooling. Additionally they put into use 110 volt AC power that our solar system offers however, they used more energy than we liked.

I chose to purchase an existing window mount evaporative cooler as well as convert it to run on one twelve volt solar energy panel, one which was able to give between 75 watts and 125 watts of energy. The existing cooler enjoyed a squirrel style fan as well as 110 Volt motor and pump. I decided to leave those there and never remove them. I included a twelve volt automobile fan as well as a marine bilge pump to the these days solar cooler. Sun cooling is achievable.

I mounted the radiator fan right before the squirrel cage fan along with the bilge pump next to the existing pump. I am able to actually make use of the original fan as well as pump on those hot nights if the sun has set. Ceating the new radiator fan positioned in front doesn't appear to do the job less efficiently as well as the normal fan does not seem to be influenced by the radiator fan being in front of it.
The very last thing that I'd to carry out was mount a solar electric powered panel somewhere close. I decided to produce a tracking mount therefore I could run the solar cooler a little bit longer in the early morning and late evening. It has proven genuinely advantageous since we gain two to 3 extra hours of usage in the daytime.
The cooler works surprisingly well for our 1600 square foot home. It's certainly not the recommended size and must be larger to provide more air circulation. The device which I converted is a 3000 cfm product and is really undersized for ChillWell (www.bainbridgereview.com) our household. The main point here is that it lets you do still work well. If I was looking to I could ultimately have a second unit and place it in another room in the house. So far I have not seen a need.
The secret to employing the solar cooler is beginning it early in the early morning and allowing it to run all day long. Other forms of ac units usually don't come on until the temperature is heating up already. By turning the solar cooling unit of ours on early, we seem to maintain at least 15 degrees cooler and lots of times almost as twenty degrees.
