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.

India: Local Manufacturer Exports First Pool Heating System to Oman

Submitted by Baerbel Epp on July 22, 2016
MuscatIndian collector manufacturer Inter Solar Systems (ISS) has recently put into operation a solar swimming pool heating system at a private villa in Muscat, the capital of Oman. Local solar thermal dealer Continental Shelf of Solar Tech purchased the 60 m² flat plate collector system from ISS to keep a large private pool inside a villa at comfortable 25 °C all year round. The photo provides a view over the coastal town of Muscat, which is said to be the world’s smallest capital with a population of only 32,000.
 

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.
