Frequently asked questions (FAQ).

How it works

Solar panels turn sunlight into electricity. The battery charge regulator controls the flow of electricity into and out of the battery bank. The energy flows into the batteries, and then to the inverter. The power conditioner (inverter) turns that electricity into a safe, ready-to-use form that flows through your home's electrical outlets. Excess energy is stored in the battery bank for later use. 

More Detail

The Photovoltaic (PV) cells in the Solar modules produce DC power, which the inverter converts to usable AC power.  ETA uses solar modules that use mono-crystalline PV, multi-crystalline PV cells, Amorphous PV,  and Thin-Film PV modules are also available for special applications.

System Components:

-Solar Modules

-Mounting Structure

- Battery bank and charge regulator (for use at night and during extended periods of low sunlight)

-Inverter 

-Wiring and AC and DC disconnect

With current technology, the sunlight falling on just half of Maricopa County could produce all the electricity used in the United States?

That the most common utility-connected, solar electric system installed on homes in urban areas costs about the same as an inexpensive new car?

That a kilowatt-hour of electrical energy is roughly equivalent to 860 dietary calories?

That there are two types of "solar panels" -- electrical and thermal? The electrical type is generally referred to as a "photovoltaic module" or a "solar module." It is a solid state device or assembly of solid state devices and produces electricity only. Thermal panels are designed to heat water or air. 

Photovoltaic modules (a.k.a. solar panels) convert sunlight into direct current (DC) electricity which can be used immediately, stored in batteries, or converted to alternating current (AC) by an inverter? 

That some inverters produce AC power of higher quality than typical utility electricity? 

That over a million homes around the world rely on solar energy as their primary or only source of electricity? Several thousand of these homes are in Arizona. 

The market for photovoltaic (solar electric) equipment is expanding worldwide at a rate of 35% per year? World wide 427 megawatts of installed photovoltaic power were sold in 2002. 

That the primary markets for photovoltaic products in the world have recently been Japan and Germany? That California is currently the primary market here in the US? 

That with proper financing, a commercial-scale photovoltaic power plant in Arizona can produce electricity for approximately the same cost per kilowatt-hour (kWh) as most residential utility customers pay?

That most photovoltaic modules come with a 25-year warranty?

That -- just like with land lines and cellular phones -- it is often more cost-effective to install a solar-electric system than to extend the utility grid?

That wind energy is generally considered a form of solar energy?

That a penny saved is like a tax-free penny earned?
