Solar Panels for Hot Water

Velux, known for its skylights, now makes solar hot water panels for your roof. Velux estimates its system will pay for itself in three to seven years by reducing your water-heating costs by 50 to 80 percent. Federal tax credits pay 30 percent of the cost, up to $2,000, and many states and utility companies offer additional financial incentives. Although the panels are new to this country, they have been available in Europe for years.
