In California, solar PV performance monitoring has been regulated by the State government. As of 2017, the governmental agency California Solar Initiative (CSI) provided a Performance Monitoring & Reporting Service certificate to eligible companies active in the solar segment and acting in line with CSI requirements.
The first versions of SMARTS were developed by Dr. Gueymard while he was at the Florida Solar Energy Center. [2] [3] [4] The model employed a structure similar to the earlier SPCTRAL2 model, still offered by the National Renewable Energy Laboratory (), but with finer spectral resolution, as well as updated extraterrestrial spectrum and transmittance functions.
And state regulators with the California Public Utilities Commission have taken a more controversial approach: drastically cutting financial incentives for homeowners looking to install solar.
The finding that solar activity was approximately the same in cycles 14 and 24 applies to all solar outputs that have, in the past, been proposed as a potential cause of terrestrial climate change and includes total solar irradiance, cosmic ray fluxes, spectral UV irradiance, solar wind speed and/or density, heliospheric magnetic field and its ...
The local irradiance near the area is about 7.4 kWh/m 2 /day [49] [50] (annual average) for a total solar energy flow in the visible spectrum of 2.717 MWh/m 2 yearly. One heliostat mirror is a 75.6 square feet (7.02 m 2) reflecting surface, [51] giving a total of 151.2 square feet (14.05 m 2) per heliostat.
As part of Governor Arnold Schwarzenegger's Million Solar Roofs Program, California has set a goal to create 1,940 megawatts [64] of new, solar-produced electricity by 2016 – moving the state toward a cleaner energy future and helping lower the cost of solar systems for consumers. The California Solar Initiative has "a total budget of $2.167 ...
