With a great deal of customers asking, the cost of solar does vary. It hinges on several things. Some of those things include product brands, distance from house/building (trenching wire length etc.), size of system, type of inverters, and more.
Solar costs do vary, but in the grand scheme of things, they do not vary by a great deal. Typically around 2.75-4.00/Watt. (add another $1-2, if you want battery storage options). Now this is all a generalization, but does allow for basic calculations. We would be happy to answer questions, or assist you in planning custom solutions for your home or business.
