What Our Happy Customers Have to Say
THE SOLAR BY CIR DIFFERENCE
Locally Owned & Operated
With a solid foundation in superior electrical services since 1976, CIR Electrical Construction Corp. built upon its expertise in renewable energy to create a dedicated solar division in 2004, Solar by CIR.
Since then we’ve become the area’s premier solar provider and a leader in environmental sustainability in our community. We’re proud of our work on notable projects throughout the region, which includes our first project with PUSH Buffalo’s Net Zero House in 2005, installations for Artpark, and the University of Buffalo.
We’re frequently selected as the preferred solar installer for NYSERDA (New York State Energy Research and Development Authority) Solarize Campaigns, including campaigns in partnership with Tonawanda, Amherst, Grand Island, Concord, Colden, Eden, Evans, and Sardinia.
With over 1,100 satisfied customers, we’ve had clients tell us that we’ve changed their lives for the better. Among the praise they’ve offered Solar by CIR, many have described us as attentive, efficient, and thorough, adding that we get the job done at a reasonable cost.
NYSERDA Quality Designation
Solar by CIR is the only local company in the WNY area to have been New York State Energy Research and Development Authority (NYSERDA) certified for two years in a row. Having NYSERDA recognition means our company consistently meets high standards of quality. Being backed by New York State speaks volumes about our top tier performance.
NYSERDA also comes with financial perks – NYSERDA offers information and funding aimed at helping New Yorkers increase energy efficiency, save money, use renewable energy, and reduce their reliance on fossil fuels.
Our customers are often impressed and pleasantly surprised by the lengths that we go through to ensure they receive the maximum NYSERDA benefits possible.
25 Year Warranty
We are pleased to boast our generous warranty that comes with many of our installs.
Depending on the equipment selected, our solar panels come with a 25-30 year labor warranty.
The LG Solar Module, which is our most used panel, comes with a 25-year warranty, including material, production, and labor.
Our Silfab Solar Panels come with a 30-year production warranty and material and labor for 25 years.
Our enphase microinverters come with a 25-year warranty.
Reliable Solar Panel Service
We are frequently called upon to service other solar companies’ installations.
If you’ve had services done by another company and you’re unsatisfied, you can still call us. We’ve stepped in and helped clients who previously worked with other electrical and solar companies. We were able to fix any issues they encountered with their current equipment.
We even had a client who, after four years of solar power production, his system failed. We were able to quickly and efficiently get the job done – and at a reasonable cost.
