USA: Commercial Systems Dominate Californian Solar Thermal Market

Submitted by Baerbel Epp on March 24, 2017
California Incentive ProgrammeThe California Solar Initiative (CSI) – Thermal Program seems to have stabilised at around 20,000 m² (or around 200,000 ft²) of subsidised collector area per year. Commercial applications dominate the statistics, although there was a spike in the share of residential systems in 2016. The peak in applications for commercial pool heating in 2014 was due to the late addition of this type of system to the state subsidy scheme. It took almost a year before the level of incentives and other requirements were set, so that all the applications piling up over that period had to be processed in 2014. The data in the chart was provided by the California Public Utilities Commission (CPUC) and shows the subsidised and installed collector area for each year.

USA: Ups and Downs of Californian Incentive Levels and Application Numbers

Submitted by Baerbel Epp on August 25, 2015
USA California StatisticsIf there were an award for the most transparent support programme in the field of solar heating and cooling, then the California Solar Initiative (CSI) – Thermal Program would get the prize. The CSI-T programme offers a regularly updated and publicly available Excel file of all submitted, approved and paid applications, and this file also includes an amazing amount of additional information, such as collector size, system supplier, contractor for the installation, total project costs or the application itself. The chart above, provided by Lewis Bichkoff, Lead Analyst of the CSI Thermal Program at the California Public Utilities Commission (CPUC), shows the subsidised and installed collector area per year. The annual volume shows significant growth from 953 m² (10,247 ft²) installed and granted during the first year to 36,641 m² (394,401 ft²) in 2014. In 2014, there was a noticeable dominance of pool heating systems, which made up 71 % of the total subsidised collector area.

Guide to Solar Thermal Incentives in Washington DC (2012)

Submitted by Raquel Ponte Costa on June 21, 2015

This report from the District Department of the Environment, Washington DC’s local environmental agency, details how local citizens can use the city’s Renewable Energy Incentive Program (REIP) to receive incentives for using solar thermal systems. Further information on solar thermal incentives worldwide can be found here.

Overview of Solar Water Heating Inputs, Data Sources, and Potential Study Results (2012)

Submitted by Raquel Ponte Costa on June 20, 2015

This report comes from The Cadmus Group, and provides information on the organizations research into and plans for expanding the use of solar thermal water heating throughout the Pacific North-West United States. It is a good example of how businesses are approaching the solar thermal market moving forward, and what successes and obstacles they see in the future.

Solar Thermal Energy (2007)

Submitted by Raquel Ponte Costa on June 20, 2015

This document was prepared in 2007 by the University of Gavle. The document gives a detailed introduction to solar thermal power, as well as descriptions of various energy applications and active and passive solar heating systems.

The report breaks down in detail the different types of solar thermal systems and collectors. Charts, graphs and photos show the various examples listed.

2009 Updates and Trends – IREC

Submitted by Raquel Ponte Costa on June 14, 2015

This report was from the Interstate Renewable Energy Council (IREC) Annual Meeting in October, 2009. The report is broken down to cover state incentives & policy trends, solar installation trends, net metering & interconnection updates & trends, and workforce development and training. For current policies that are mentioned to withstand solar growth, they mention the Energy Improvement and Reinvestment Act (part of the federal “bailout bill” in 2008) and the American Recovery and Reinvestment Act (part of the “stimulus bill” in 2009).

Solar Thermal Collector Market in IEA Member Countries (2002)

Submitted by Raquel Ponte Costa on June 13, 2015

This was a study prepared by the International Energy Agency (IEA) in 2002. The study documented the collector areas previously installed in the 22 IEA member countries and to identify the contribution of solar plants to the supply of energy and how it cut down on CO2 emissions. It has all the member countries listed with the total collector area, for different types of solar thermal systems, with energy savings equivalent.

Green Institute Issue Brief on Solar Energy (2008)

Submitted by Raquel Ponte Costa on June 13, 2015

This report was issued by the Green Institute in 2008 and discusses the option of a “solar carve-out” to build Minnesota’s solar future. To develop Minnesota’s renewable sources beyond 25 percent, development of additional renewable energy will be necessary, specifically solar technology. A carve-out is an addition to a renewable energy standard (RES) that specifies a portion of the RES needs to be met with a particular technology – solar.

Solar Thermal Solutions in Boston and the Northeast (2008)

Submitted by Raquel Ponte Costa on June 13, 2015

This PowerPoint was developed by KeySpan in 2008. It covers why they promote solar thermal water heating in the Northeast, applications, market barriers and a forecast for the future. The presentation introduces the different solar thermal programs that KeySpan offers including domestic hot water, pool heating, space heating, process hot water and solar assisted cooling. It also mentions the different applications where all this solar thermal energy can be used and what type of savings will be seen.
