That depends on the goal. In a situation where reliable utility power
is readily available solar may not be an economical choice.

But in a remote location solar is a reasonable option. The roof
shingle panels offered by ECD Ovonics are relatively inexpensive and
easy to install.

Of course if oil goes through the roof the economics change. Who
knows?

The cost is somewhere around $100 per watt, does that sound affordable
in any household context?

The only advantage to shingle panels is that they generate electricity
directly. The heating tubes developed for GPS satellites are far more
effiecent at generating heat and take up a lot less space. A properly
set up system will even heat your home on a moonlit night.

No solar system is without maintainance. It needs to be cleaned,
checked for leaks, protected from impact damage etc. The path to the
sun must be clear at all times which may mean triming trees.

Another problem is that they generate low voltage DC. So either you
figure out how to run your home on low voltage DC, have two seperate
systems, or lose power converting commercial electrictiy down or solar
up to your power line standards.
