TerraSol Costs and Installation Process


TerraSol offers prospective customers two payment paths: either cash payment or financing. A cash payment involves paying for and owning the solar system whereas financing deals with repaying a flexible, fixed payment plan that requires an application process to see if the customer qualifies.

Due to the company operating in multiple states, it is difficult to pin down a price bracket; also the company does divulge its prices on its official channels such as its website or social media platforms. As such, TerraSol was contacted through a secret shopper with questions regarding the company’s prices and some of the intricacies of the installation process, however, the shopper was not answered.



The general installation process involves the following steps:

  • A site visit with TerraSol personnel to discuss the customer’s needs, expectations, and current power usage while an estimate is given
  • Designing the solar system and drafting a proposal for the installation
  • Town approval, inspection, and permits for the solar system
  • Installation of the system


TerraSol Legitimacy

Listed on the Pennsylvania Office of Attorney General’s government site, TerraSol is a licensed business with its current license set to expire in November, 2023. Alongside the license, it has the following accreditations to consider: 

  • The company has a BuildZoom (BZ) score of 95, placing the business above 78% of 125,106 contractors in Pennsylvania
  • TerraSol is not an accredited business by Better Business Bureau (BBB)



The company makes itself available to provide answers to any problems or questions after installation. Largely, complaints regarding the maintenance of panels after installation have been minimal as the installation process has been stellar.


Customer Experience

Customers are highly satisfied with TerraSol’s professionalism, sales process, quoted prices, scheduling, installation quality, and post-sales support. Two clients, specifically, refer to how the end price was cheaper than what they were expecting and what rival companies offered them.

In general, the staff of TerraSol are knowledgeable, readily available, and prepared to help customers through the process by educating and answering any questions. Robert Santoleri, the Vice President of the company, is fondly, and quite frequently, referenced in the glowing customer reviews, alongside a few other key team members.



The SolarEmpower View (Conclusion)

TerraSol Energies, Inc. reviews positively across the board: as a business that was established in 2009, it has longevity, over 10,000 completed projects, over 100 customer reviews, numerous recent reviews, and an average rating of 4.5/5. The work the company has done over the years can be tracked very easily and the business is highly transparent about its processes and equipment used.

The only improvement the company could provide is to make an easier and more streamlined method for prospective customers to get answers to questions such as information on prices, financing options, and details of their installation process.
