Great installation work. Sigen Energy battery and 14 × 510 W panels all done in a day. Only two weeks in, but already generating over 60% more than I’m using.
Excellent installation of our Sigenergy solar system and EV charger by D Cookman. Special thanks to Mihai, whose skill, professionalism, and attention to detail made all the difference. Highly recommended team.
Very happy with the 27-panel installation that Dave and his team did for us. We're cooking on photons now!
We had Dave Cookman's company install 21 solar panels and a SigEnergy based system on our property this July (2026). It is too soon yet to tell what the annual financial benefits will be, but the performance of all components has been great so far. Dave gave us a very competitive quote and has been easy to work with and responsive to a few niggles we had after installation. I am happy to recommend D Cookman Electrical.
Had 17 panel and Tesla storage installed . Great team of Professional lads. Highly Recommend.
