Solar Hybrid Systems
Hybrid solar systems generate power in the same way as a common grid-tie solar system but use batteries to store energy for later use. This ability to store energy enables most hybrid systems to also operate as a backup power supply during a blackout, similar to a UPS system. What is the difference between PV and Solar thermal?
Geothermal Energy
Marchetti designs affordable commercial and residential geothermal heating & cooling installations for those suffering from high energy bills. What is a geothermal system? A geothermal heat pump is a central heating and/or cooling system that adds or removes heat to or from the ground to cool in the summer or heat in the winter. Geothermal heat pumps collect heat absorbed at the Earth’s surface from solar energy. How does a Geothermal system work?
Combined Heat & Power (CHP) System
