We were keen to get Solar energy and contacted Harrisons for the project. Four things impressed us. First, Carl and Sian were very clear in explaining the various options, decoding all the jargon so we did not feel like numpties, clearing up any misconceptions we had. We felt entirely comfortable through the decision-making process, and were very happy moving forward. Second, the equipment we ended up with is elegant, robust, and frankly enhances the appearance of our house - in particular, the Tesla Powerwalls look better than any kitchenware we have. Third, the installation team was very precise and exacting, and every detail is completely perfect - we literally cannot find anything that is ill-fitting or jars. In addition, they were a polite and pleasant team to deal with over the day, and did a timely install despite winter weather and a challenging location. Fourth, Carl and Sian are a pleasure to deal with in terms of logistics and business matters, with clear and timely responses. We recommend this team +++
