About Southwest Solar:
We are a small, innovative company that has been in the solar cooling business for 24 years. We are committed to developing low energy coolers made out of high quality materials and are environmentally minded. We build products that will outlast the competition. We are the manufacturer of the many sizes of the SOLAR CHILL evaporative cooler.
We specialize in solar powered ultra low energy evaporative cooling. We offer the most energy efficient line of evaporative coolers in the world, called the SOLAR CHILL. We have DC or AC low energy solutions for cooling your home, office, greenhouse, warehouse or vehicle. All of our products are can be directly run off solar panels and are and offered in a variety of voltages including 12, 24, and 48 VDC, as well as 120 and 240VAC, or 3 phase power. We also have coolers for vehicles and trucks to meet compliance with the new No Idle Laws, or over the road trucks. Most of our coolers are Stainless Steel or plastic for longer life and have a 5 year warranty against rusting out. We also build solar hot air heaters, solar ovens for cooking, design off grid solar battery based electric systems, and design “Cool Towers” which have the lowest possible energy cooling solution.
Note that when using our DC coolers they can be connected directly to solar panels. And the cooling hours are usually limited to hours of about 8 AM till 4 or 5 in the afternoon. If no batteries are used, the cooling performance will depend on weather and clouds. Also the panel size will have to be matched very close to the power requirements of the cooler, or you will have problems with high voltage shortening the life of the fan and pump motor. We can help you size the solar panels necessary to avoid problems. In general it is much better to have a battery in the system and a solar charge controller to keep the voltage in the right range, and have more consistent cooling performance. Greenhouses are one application where a Solar Chill is directly wired to a solar panel. Because the harder the sun shines, the better the cooler works. They go together like bread and butter!
With the Solar Chill make cooling one of your lowest electrical loads in your home or business. Also, the12 volt Kar Kool evaporative cooler will save gas since there is no mileage penalty as with AC. No Idle Laws for trucks have been passed in all 50 states which limit truckers from idling just to keep the the AC running while taking a sleep break. With our low energy coolers the driver can stay cool with the engine off, and not pollute the air while cooling the cab. These vehicle coolers are very low energy and will easily run all night with out killing the battery. Check out our products page for the compact new over the road truck cooler.

Tucson Arizona has been the home of Southwest Solar since 1995. With over 48 years experience in evaporative cooling and 44 years in passive and active solar heating & cooling, Bill Cunningham P.E., Southwest Solar's head Engineer, and original owner and founder, got his Mechanical Engineering degree from the University of Arizona, and has called Arizona home since 1970. He Worked with the U of A's Environmental Research Laboratory in Low Energy Heating Cooling solutions, greenhouse heating and cooling Engineering, and Passive Solar heating design and innovation. He was the principal investigator for " Passive Downdraft Cool Tower" research, and "Wavelength Selective Greenhouse Films", and "Liquid Foam Greenhouse Insulation and Shading".
Southwest Solar was founded on a few basic principles:
1. Aid in the overall health of the earth by providing the lowest energy cooling systems available in our world.
2. Provide easy access to knowledgeable, be courteous and efficient with sales staff and technical support
3. Be upfront about all shipping charges and returning policies
4. Make every effort to make our site full of easy to read, easy to understand and easy to navigate material and products
5. Give our honest opinion on all products and comparisons
6. Make sure that the customer is satisfied
We have found in that these simple and basic principles are not often followed by many other competitors and companies, and we aim to change that, by providing these principles in our business we set an example for all other companies. Our pledge to you is that we will do all that is within our reasonable power to make you happy.
Our number one goal is to get you the correct product at a fair price that is going to make you happy, and the planet healthy and sustainable.
