Transitioning to Solar: A Satisfying Experience

With the rise in energy costs, we decided to invest in solar panels and a battery installation. Supporting a local business was crucial for us to help them compete against larger companies. Among three local providers, one stood out. I contacted a representative who quickly arranged a visit within the hour. During the visit, he presented a thorough report detailing our needs and, importantly, what was unnecessary. He provided a quote and encouraged us to seek additional estimates, which we often do. However, his respectful approach and the professionalism of the report convinced us to proceed without looking further. The installation date was set, and work began on time. One of the installers proposed setting up 13 panels, which was a challenging task due to our loft windows. Remarkably, he completed the installation without leaving out any panels, something we thought would be difficult for others to achieve. He demonstrated great commitment, working diligently from morning until evening without complaints, even in the cold weather. The panels were installed quickly, followed by efficient electrical work from another team member. Throughout the process, he kept us updated and limited our power downtime to under an hour. He even stayed late to ensure everything was finished and that we understood how to operate the system and its app. Despite our usual practice of obtaining multiple quotes, the service's customer-oriented approach and dedicated team made our choice easy. We are also planning to have a heat pump installed by them in the upcoming year, confident it will go as smoothly as the solar setup. We intend to recommend this company to our family and friends, given our satisfaction. The solar panels are now producing more electricity than we use during the day, and the battery effectively stores energy for nighttime. We look forward to receiving payments for surplus energy from the grid soon.

Rising Energy Costs Led Us to Solar

With energy prices increasing, we chose to install solar panels along with a battery system. Supporting a local business was essential for us to help them compete with larger firms. Of three local options, one stood out. I reached out and spoke with a representative who quickly arranged a visit within the hour. During this visit, he provided a comprehensive report detailing our needs and, importantly, what wasn't required. He offered a quote and encouraged us to seek other estimates, which we typically do. However, we were so impressed by his respectful approach and the professionalism of the report that we decided to proceed without looking for further quotes. The installation date was set, and work began on schedule. One of the installers suggested setting up 13 panels, which was a complex task due to our loft windows. Remarkably, he managed to complete the installation without missing any panels, something we doubted others would attempt. He demonstrated his commitment, working tirelessly from morning until evening without complaints, even in the cold. The panels were installed promptly, followed by efficient electrical work. Throughout the process, he kept us informed and minimized our power downtime to under an hour. He even stayed late to ensure everything was completed and that we understood how to operate the system and its app. Despite our usual habit of seeking multiple quotes, the service's customer-focused approach and dedicated team made our decision clear. We also plan to have a heat pump installed by them next year, confident it will be as smooth as the solar installation. We will recommend this company to family and friends due to our satisfaction. The solar panels are now generating more electricity than we consume during daylight hours, and the battery efficiently stores energy for nighttime use. We anticipate receiving payments for surplus energy from the grid soon.

Smooth Solar and Heat Pump Installation

I recently had a solar system and a heat pump installed by this service. Throughout the process, their knowledge was impressive, which was a key factor in my decision to proceed. The installation went very smoothly, thanks to the excellent staff on-site. After installation, I received all the assistance I needed to learn how to use the system effectively. From the initial contact onward, the office team was outstanding, ensuring all administrative work was handled efficiently, resulting in smooth delivery on time. I would definitely recommend this service. The heat pump system performs significantly better than a gas boiler; I wish I had undertaken this project sooner. Thank you!
