Inefficiencies in the rest of the balance of the system reduce energy delivered even farther. Whereas solar hot water and other thermal collectors vary from 30 to 98% efficient, with the state of the art evacuated tube collectors with selective surface coatings that collect even outside of the visible light spectrum performing at the top of this range. Whole system efficiencies will vary with the insulation on the balance of the system, but a well-done solar hot water system is typically about twice as efficient at delivering the solar energy to the home than solar electric, so if you wish to see your money come back to you as soon as possible and you use water, you should consider solar hot water before solar electric.

I just added you to my Google News Reader. Keep up the good work. Look forward to reading more from you in the future. I found your blog on google and read a few of your other posts.
