Great Job Team Simmark with our solar power and Tesla battery install. saving $4k PA + the security of backup power whenever there’s a blackout. A fully professional team, prompt support and impressive result.
Mike J.I contacted Simmark regarding a solar system having been let down by another supplier. It was like chalk and cheese. Upfront service was fast and professional and the work was carried out by many employees all of whom were the most respectful bunch you would wish to have at your home. Our new panels were great but the Tesla powerwall 11 is the bees knees!
Muddy D.They’ve helped set up many aspects of our farm, and have done a great job! They are always polite and helpful, and they do very neat and thoughtful work. Their pricing is transparent and reasonable. Highly recommended.
