• Know Your Rights

    Arizona law protects individual homeowners’ private property rights to solar access by dissolving any local covenant, restriction or condition attached to a property deed that restricts the use of solar energy. This law sustained a legal challenge in 2000. A Maricopa County Superior Court judge ruled in favor of homeowners in a lawsuit filed by their homeowners association seeking to Read more
  • Agua Caliente PV Power Plant Among World’s Largest

    The Agua Caliente solar farm near Yuma features First Solar’s thin-film cadmium-telluride (CdTe) solar modules. Located 65 miles east of the city of Yuma, Arizona, this plant is one of the world’s largest operational PV power plants with 290MW (AC) connected to the electricity grid. Read more
  • Solar Hot Water

    There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which don't. The typical solar water heater is comprised of solar collectors and a well-insulated storage tank. The solar collector is a network of pipes that gathers the sun's energy, transforms its radiation into heat, and then transfers that heat to either Read more

  • Solar Building Design in Arizona

    The idea of using the sun to meet the energy needs in our buildings has been with us since the time of the Greeks, with some of the design manifestations even evident in the prehistoric structures of Arizona and the Southwest. There is a great historic tradition for Arizona buildings that utilize our most abundant resource, and the current increases Read more
  • How Not to- Battery Connections

    Photo shows the situation after a battery discharge test at 300 amps was terminated on a 1530 AH IBE battery string when one post melted. During the discharge test all cell voltages are logged. The sum of the cell voltages was 2.73 volts lower than the 48-volt string voltage. This is an average of 118 mv per inter-cell connection, 5-10 Read more

“A lie gets halfway around the world before the truth has a chance to get its pants on.”  --Winston Churchill

24 November 2016

The future is not what it used to be.

In the 1990s, the push for electric vehicles gained momentum in response to national security concerns over our reliance on imported fuels and tailpipe emissions.

Solar Photovoltaic Resource

The solar photovoltaic resource maps provides average daily total solar resource information on grid cells of approximately 40 km by 40 km in size. The insolation values represent the resource available to a flat-plate collector, such as a photovoltaic panel, oriented due south at an angle from horizontal equal to the latitude of the collector location.

Concentrating Solar Power Resource

The concentrating solar power resource maps provide monthly average daily total solar resource information on grid cells of approximately 40 km by 40 km in size. The insolation values represent the resource available to concentrating systems that track the sun throughout the day. Such systems include concentrating solar power systems such as trough collectors or dishes.

Because the resource data are for a tracking system, the available resource tends to be higher than for non-tracking systems in sunny areas, but lower in cloudy areas, because under cloudy conditions tracking systems are unable to use any of the solar resource, which is obscured, whereas flat-plate collectors can still make use of the available sky radiation.

Biomass Resources

The biomass resource maps show county-level estimates of biomass resources available for biofuels production or biomass power stations. The map includes only the resources available from crop and forest residues. They do not include managed crop or forest resources, urban residues, municipal solid waste (MSW), or landfill gas (LFG).

Sample images from movie.

Movie Summary:

This video examines solar water heating. Solar water heating is one of the most cost effective ways to use solar energy. Though there are many different types of solar water-heating systems, the basic technology is very simple and illustrated in this video.

Runtime is 2 minutes 8 seconds.
