Watertown Massachusetts requires solar on new commercial buildings

On November 27, Watertown, Massachusetts, voted to set a requirement that all new commercial construction greater than 10,000 feet, retrofits of sites that are greater than 10,000 feet, and all new residential structures with ten or more units must include solar power.

Last year,  South Miami mandated new homes to have 2.75 kW of solar for every 1000 square feet. In 2013,  Lancaster California  kicked off the trend, followed by Sebastopol, Santa Monica, and San Francisco, all requiring solar with new residential construction. Of course, come 2020, any new residential construction in the whole California will some. This mandate could lead to lower installation costs

Requiring a solar system equivalent to 50% of the roof area of the building and 90% of uncovered areas of garages. The new zoning requirements did allow for exceptions where the solar ready zone is shaded for more than 50% of daylight hours,

There is a continuing trend to expand solar in residential and commercial construction nationwide. With the increase of solar installations, the materials and the processes to install the solar will continue to decline. This cost reduction, combined with and local or federal rebates,  will help make it more affordable for existing residential and commercial entities looking to install solar on existing buildings.
