I can’t thank 1 Source Solar enough for how professional and responsive they were. I installed panels on 8 buildings in 8 different towns across Iowa. It was a big logistical challenge from the start, but the whole 1 Source team was extremely helpful. I was really blown away by how knowledgeable they were on the technological details behind the best possible installation. Our utility bills have plummeted and the returns have exceeded my most optimistic expectations. If you’re not calling up 1 Source for a quote you’re missing out.

A+!!! Just got my system installed and I cannot say enough great things about this company. Throughout this whole process they have been beyond helpful. We have always been informed about what would happen and when with the project. As with any large projects, complications arise. When they did, we were well informed and everything was addressed in a beyond satisfactory manner. Everyone from initial sales to the installation team to the electrician were professional and went the extra mile to do a great job. They were always available, at any time, for any questions and always had the answers. They knew all about tax credits, federal and state. They helped with all the paperwork to make it effortless. They knew about current issues being debated regarding solar power at the state level and how we’d be impacted by that. They made sure to place the panels aesthetically on our home as well. They truly thought of everything and then some. Highest possible recommendation. We could not be any happier with this company.
