Williams Solar (the trading name of Williams Evergreen Ltd.) today ranks as one of the most experienced developers of solar photovoltaic (PV) projects in Barbados, having installed over 10MWp of solar PV to date. The long list of solar generation systems successfully engineered, procured and constructed by Williams Solar ranges from modest residential premises to large-scale commercial properties, including banks, offices, shopping complexes, and factories, in Barbados and the wider Caribbean.

As a subsidiary of the well-respected Williams Industries Inc. company, Williams Solar is able to draw upon over 40-years of group experience to provide clients with tried, tested and proven quality in engineering, procurement, and construction. Recognizing that the longevity of their systems provides even greater value for their clients, Williams Solar also focuses heavily on mitigating any potential risks to preserve the life of the system for twenty-five years and beyond.

Client Testimonial

Clemco Electrical Services Inc. – Electrical contractors & suppliers
Our 5kW and 7kW systems were installed and commissioned in April 2014. Since this time we have seen a considerable reduction of our electricity bills. The installations were carried out in a very timely manner and the quality of the work and the equipment used have been exceptionally good. The performance of our systems to date has been within the stated parameters. One of the outstanding features of the Systems is that all the relevant data regarding the system can be viewed online, which has allowed us to keep track of the system’s performance. Management together with their technical team have been very responsive towards any queries we had and their after-sales service has been very good. I, therefore, have no hesitation in recommending Williams Evergreen to anyone intending to have a Photovoltaic System installed.
