As a renovator and and builder who wanting enviromental priorities, I see that solar shingles are becoming easier to market and install. Do you have any installation stories or advice to share? Dow Chemical has the exciting new "powerhouse" shingle which can be nailed on by a roofer and wired by the electrician. Will solar roofs be this easy for the general contractor to incorporate into the next roofing job? What is the latest news on solar shingles?
