"The initial visit was carried out by an engineer, not a salesman and there was a clear explanation of all the aspects of the installation with no pressure selling. We went to their premises (they have sinced moved) to ensure that there was substance behind their presentation and we were pleased to find a professional set up staffed by people who were keen and knowledgeable about their product range, We were provided with a computer simulation of the installation as well as month-by-month prediction of the power output we could expect to get from the system. These outputs have been exceeded every month so far, so we are very pleased "
