"The tech showed up a little early which I appreciated; nothing worse than being late for an appointment. He quickly diagnosed the issue with our solar system and is working to get a new inverter under warranty from the manufacturer. He also installed a critter guard to keep the birds from nesting under our panels."

"I am very happy that BlueCore sent a qualified electrician to fix the inverter on my solar system. The first company that came out did not even take the cover off the inverter and told me that could only replace it at a cost of $6000. Yikes !! Blue Core’s electrician had it fixed and working in less than 2 hours. Great job! Highly recommended the company."
