Although we did not move the Earth and Sun (pun intended) in 2018, Gresco did make significant strides in becoming a stronger player in the solar market. We completed six 50KW projects for the Alabama Municipal Electric Authority (with three remaining) and we completed a 1MW project for Irwin EMC in Georgia. As we mentioned in our last solar update, Gresco is set up as a National Distributor for Sungrow inverters. To date, our sales to solar contractors in US have topped $500,000!

In your travels, you have probably seen solar farms. A brief explanation of how solar panels work might shine some light (more pun intended) on the subject. Please keep in mind, I am not an engineer or a chemist.

Put simply, solar panels are placed in the best position possible to absorb the most sunlight or photons. The panels are made of two layers of silicon, which is a conductor of electricity. The silicon absorbs the photons, turning them into electrons, or current. The current flows between the layers of silicon to the inverter, which converts the direct current (DC) into an alternating current (AC) that is then put on the electrical grid for utilities to use. The more the sun shines, the more energy is produced.


Although the US Solar market slowed down in 2018 due to tariffs, experts still predict solar will be a major economical source of alternative energy in the future. Gresco stands ready to play our part in this growing market!
