This is a letter written by the Utility Solar Water heating Initiative (USH20) to the Florida Public Service Commission in 2008.

USH20 is a coalition of utilities and the solar thermal industry that focuses on implementing cost-effective solar thermal solutions for utilities and customers. Their industry members supply nearly all the SWH equipment being installed today.

This short document, produced by the International Energy Agency, provides a summary of the solar heating and cooling situation in 2009.

The document is divided in different sections: market status; economics; outlook; system related aspects; environmental impact; technology status development; which touch upon different issues ranging from the installed capacity, to solar resources of different countries, drivers and barriers for growth, etc.

This Code of Practice was published by the New Zealand Solar Industries Association (SIA) to provide guidance to manufacturers, suppliers, and purchasers of solar hot water systems on manufacturing and installation standards to be observed in New Zealand, especially for household installations.
