At Pure Luminescence Inc. quality is our guideline. We have selected the very best system to utilize solar output for our customers. We use Ontario made solar panels, reliable micro inverter technology, and superior monitoring equipment. We have designed these systems to not only perform during the 20 year period of the contract, but long after as well.
The Micro Inverter is the best thing to happen to the solar industry since the sun. They have countless advantages over string inverters. Pure Luminescence Inc. has chosen to use Micro Inverters over anything else, because they last. When entering a contract for 20 years you want to be certain products will last. A string inverter carries a MTFB (Mean Time before Failure) of 10 – 15 years while our micro inverter is rated MTBF of 331 years. During the contract, systems with string inverters will face replacements and increased periods of failure.
