Let's face it - 'solar on every rooftop' is becoming a reality. Businesses invest in solar power for tax purposes, environmental stewardship reasons and as future cost cutting measures. The benefits have become obvious. A 25 kW solar electric system saves $5,000 in electricity annually, recovers its entire cost in the first five years, and generates $9,000- $15,000 in Solar Renewable Energy Certificate (SREC) income for the next ten years.

With the widespread renovation of aging mill buildings and warehouses, developers are already in the "Green" business. As you turn unused space to revenue generating property, keep in mind long term earning potential gained through controlling operating costs. Making appropriate energy efficiency improvements attracts and retains tenants and increases property value.

The key is to have a comprehensive plan that addresses long term energy costs. By implementing low cost or free efficiency measures, you can save 10-50% on the building operating costs. Reducing your current energy consumption by as little as 10% can save $10,000 - $75,000 on the installed cost of a solar electric system.
