3 kW system for US$12,000.

Currently China is shipping solar panels for about $1 per watt. (Apparently for less than $1/W.)

A 3 kW PV system would cost $3,000 + inverter and hardware. Under $5,000 or less than half of the Stirling system.

It also would have no moving parts and and expected lifespan of 30, 40, 50+ years. Almost no operating expenses.

You could get almost three times as much output from a PV system. The price of PV has fallen so rapidly that it’s knocking thermal solar out of contention.

Speaking of rural workshops, Sun Electric is selling “laminates” – solar panels without junction boxes and frames for $0.58/watt. Gluing on a junction box, soldering a couple of wires, and building a simple frame is something that requires little equipment and could be done in a basic workshop.

$12,000 would buy over 20 kW of solar.

Dec 2011 . What i the update. I have been studying Open Source ecology, i.e no patents/licenses etc. of a 40 sq meter, solar panels , made of smaller mirrors, which track the sun,, by hand, and can be made in a rural workshop, in developing countries. Approx cost Rs 150,000 (approx US$ 4000). Couple with a 3-5 HP Stirling engine, (cost approx Rs 300,000), i.e. about US$12,000 for a 3 kw, electrical power output. With hot water of about 5-10 KWe heat equivalent for heating etc.

We are working on the details, designs etc. International cooperation/collaboration welcome.

Does anyone have info on how much they cost or how to aquire one of these?

I lived in Arizona for 25 years and one thing I learned for sure. If there is any way to screw something up, Phoenix will find it. If there is no way, they will invent a way.

Stirling Energy Systems will discover for themselves they should have placed this in New Mexico.

I also did the math and got exactly identical

results to PVinsights . 21.41 pcnt.

[based on 1 KW per square meter .]

sailingsoul has a point…

You know what the dirty little secret behind smart meters is don’t you?

Make a meter smart enough to figure out TOU and how many VA get pumped into your home, i.e. a 25W CFL may consume 50VA, how much harmonics are coming out of your house, and how poor your homes power factor is…

As a result your power utility can charge you for what time you ran anything with a motor (inductive device), how many VA your lights and appliances draw (not everything is a resistive load), how much harmonics your cheap appliances create, and how poor your homes power factor is…

All ways to take more of your $$$
