Quite the opposite! A study performed by ICF Consulting determined that for every $1,000 in energy savings you provide to your home, it increases the resale value by about $20,000! Another study on solar homes in California by the National Renewable Energy Laboratory (NREL) concluded that homes with solar sold, on average, 20% faster and were 17% more likely to sell than homes without solar systems. This trend is being seen across the nation as energy costs are becoming increasingly important to prospective homebuyers.
