The Second Church of Dorchester has completed installation of a 25-kilowatt solar array atop its 211-year-old church building to kick off the Codman Square Goes Solar Initiative, which seeks to expand access to renewable energy in low-income communities.

Resonant Energy is seeking additional homeowners and property owners to sign up to host solar installations. Bundling multiple projects can reduce construction costs up to 30 percent, said Isaac Baker, co-president and founder of Resonant Energy. The program has more flexible credit score requirements than many solar programs, enabling more residents with qualifying roofs to participate, Baker said.

There is no up-front cost and residents receive renewal energy credits to reduce their electric bills, with the excess credits sold to a third party.

Boston-based Sunwealth financed the project and two previous ones at Bethel A.M.E. Church in Jamaica Plain and Church of Saint Augustine and Saint Martin in Roxbury. Combined the three projects will generate 70 kW of electricity and save the churches more than $180,000 in energy costs.

Other members of the initiative include Codman Square Neighborhood Council, Codman Square Neighborhood Development Corp., Community Improvement Assoc. and the Boston Metro East Community Energy Co-op.
