I’m giving just 1 star purely for the after sales care. Installations went really smoothly and professionally, nothing to complain about. Installation happened in early August. We have tried to contact the office to arrange for an engineer to visit, we have few issues with the application and problems with the system itself. Still no visit or explanation from anyone and we are in October!! We are very disappointed with the customer care, bearing in mind the amount of monies we have spent on the product. Seems like there is nobody in the there willing to help with the very important issues we have been having. At the moment based on the poor customer care, highly unlikely I will be recommending a product from Solar Project.
