Not at all. It can done very inexpensively. Any fool can spend $70,000 but it takes a little knowhow how to get the same thing for $5000.

Solar hot water is practical, even here in far northern New England in the summer.
I built and installed my own system for under $500 3 years ago.
It paid for itself in less than 2 years.
Free hot water from Memorial day to Columbus day this year except for 2 days when it was cloudy for several days when I fired up our System 2000 boiler.
If you can design and build a solar hot water system on your own it can be pretty cheap.
Solar electric is still pretty expensive per amount of energy produced. That will change eventually.
