  • Learn how to save money and improve our

  • environment by using solar power

  • Solar Potential

  • history of world energy

  • carbon footprint

  • solar:  natural light, hot water, panels, thermal

"Solar Power At Home" 6 Mar 2014 

by Doug Elgin (ASA Pres.)

  • How does PV work?

  • Types of PV

  • Pros & Cons of Solar

  • Installation Types:  Grid-tied & Off-Grid

  • Installation Choices:  Roof, Ground

  • Mounting Choices

  • Incentives & Payback

  • Grid parity

  • Installing can cost 2-4 times the cost of the PVs

"Off-Grid Solar Power" 20 Mar 2014 
by  Brian Nothnagle (Huntsville Solar

  • Hierarchy of the structure of a Solar Array, Solar Panel, Solar Module, Wafers

  • 2 types of Solar Modules:  Poly crystalline & Mono crystalline, and their pros & cons

  • What is a Charge Controller?

  • What is an Inverter?  DC to AC Inversion

  • Design Considerations  1) Solar - orientaion, tilt, shading, distance from Charge Controller, Array Capacity, 2) Structural - mounting & Structural Integrity

  • Electrical - location of components & electrical connections

  • lecture then convened to the parking lot where Brian showed us his "Off Grid" van, complete with solar panels, Inverters, batteries and electrial outlets for power in the field, as he installs at the work site

YOUTopia Solar Energy Talk Series

presented at the H'ville Botanical Garden


In June, several of us delivered a series of 5 talks on Solar Basics at the Botanical Garden.

Contact the WebMaster if you wish to recieve a copy of the presentations.


In 2006 an agency within the

U. S. Depart of Energy reports

The most widely used and readily available residential renewable energy is geothermal energy

   from ground source

heat pumps


Your solar panel / PV system is more efficient (generates more electricity) in cold weather.

When generating power,

solar panels quickly heat
up to 90 F degrees above outside temperature.


Use the blue bins for paper (mail, boxes, magazines), anything metal (cans, aluminum foil) and plastic. It cuts down on garbage and can be reused.  China buys our scrap metal.

"Biofuels" Thursday, July , 2014

by Doug Elgin (ASA Pres.)

  • Biofuels are fuels manufactured from plant and animal life or organic waste NOT fossil fuels

  • Bioethanol, Biodiesel, Cellulosic Ethanol, Butanol, Fuels from Algae

  • a renewable resource, most reduce GHGs

  • Biofuels show promise to ultimately cost less than fossil fuels

  • Biomass – plant matter for energy use

  • Cellulosic Ethanol is coming

  • You Can Make Your Own Biodiesel

  • Algae Has Great Promise for Biodiesel

"The WHY of Renewable (and Conservation of) Energy" Thu, Oct 16, 2014    by Doug Elgin (ASA Pres.)

  • Renewable energy is energy derived from sources that produce no GHGs or recycle them in the short run

  • What?  Biomass, Hydropower, Biofuels, Wind, Solar, Geothermal, Ocean power

  • Why?  paybacks & reduce Green House Gasses

  • Photovoltaics:  Installation Choices, Incentives, Payback, Emergency

  • Ground-Source Heat Pumps

  • Saving Energy around your house

  • Why Solar Water Heating?

  • Greenhouse Gases & CO2 & Global Temperatures & Climate Change

"Ground Source Heat Pumps" Aug 19 by Keith Key, P.E., from Geothermal Solutions

In really cold weather, a GSHP can be

 10 times more efficient

than a regular Air Source Heat Pump

  • Diagram of an Air Conditioning System

  • SEER ratings

  • calculating "Tons" for your home

  • What is Geothermal Heat Pump?  in summer exchanges warm air temp in house for cooler ground temp & winter :  the opposite

  • bonus:  excess heat provides free hot water for your home during cooling months with min. upfront cost

  • Closed & Open Loops

  • 55 year No Leak warranty

  • A typical homeowner, uses about 60% of

    their total energy consumption for heating,

    cooling and hot water

  • Geothermal System Benefits

  • GGR equivalent

  • the IRS Energy Credit

"ASHRAE and Energy" Sept    

by Morton Archibald (ASA and Affordable Energy)

  • sssssss

  • Perpetually renewing power from the sun has fueled life on Earth since its first spark

  • Photovoltaic, PV, means electricity from light

  • PV cells are built on wafers of silicon made from ordinary sand and quartz

  • The history of the solar industry from 1954 when Bell Labs invents  the first modern silicon solar cell

  • Albert Einstein won the Nobel Prize for his 1905 discovery of exactly how light caused what was then called the photoelectric effect

  • A photon is a packet of light energy

  • Silicon to solar wafers (crystallized silicon) to solar cells to solar panels (modules)

  • Diffusing creates a positive-negative junction

  • metals are printed on both sides of the cell to collect and forward the power

It’s time for an energy foundation in harmony with the planet.

It’s time for a
solar revolution.

Sun Activation

A) Photons bombard and penetrate the cell.

B) They activate electrons, knocking them loose in both silicon layers.

C) Some electrons in the bottom layer sling-shot to the top of the cell.

D) These electrons flow into metal contacts as electricity, moving into a circuit throughout a 60-cell panel.

E) Electrons flow back into the cell via a solid contact layer at the bottom, creating a closed loop or circuit.

ASA has Speakers every Month at our
