What are the benefits of installing solar hot water/space heating systems?

Sunlight is a clean renewable energy resource that has been used for many years. Some benefits of solar water/space heating are:

1 * Produces no emissions and is replenished naturally
2 * Reduces greenhouse gases
3 * Saves the release of 2 lbs. of carbon dioxide (CO2) for each kilowatt-hour (kWh) produced
4 * Saves the use of one-half gallon of water for each kWh of solar energy produced
5 * Saves the release of other emissions that result from the burning of fossil fuels such as nitrogen oxides, sulfur dioxide or mercury
6 * Makes use of one of Arizona’s greatest natural resources - sunshine
7 * Provides customers with options to reduce their electric bills.
8 * Is very cost effective with payback periods of as little as five years
