PV Solar vs Geothermal
In southern Delaware, we are planning to build a 2500 square foot house that will meet EnergyStar standards. Because of the dimensions of the lot (50'x 110') and the direction (north to south). The roof peaks will be facing east and west. Despite this I've had two solar companies tell me that the house will have sufficient exposure. I am also looking into geothermal. Does anyone know which system PV Solar vs Geothermal is more cost effective regarding return on investment snd lowering energy costs long term? Also how do I get an indepent site evaluation of my solar exposure preferrably by someone who is not also trying to sell me the sytem?
