How We Install Sigenergy Systems
At UK Green Energy Installations (UKGEI), our goal is to make your transition to smart energy as simple and stress-free as possible. Thanks to Sigenergy’s innovative plug-and-play design, our installation process is faster, cleaner, and more reliable than traditional solar and battery systems.
Every Sigenergy installation begins with a tailored energy assessment to determine the right setup for your property. Our MCS-certified engineers then design and install your system — from Sigenergy SigenStor all-in-one solar and battery storage to SigenStack modular units — ensuring maximum performance and efficiency.
Because Sigenergy’s products are modular and pre-configured, installation time is dramatically reduced, and there’s less chance of wiring errors or performance issues. This means a more dependable system, quicker turnaround, and minimal disruption to your home or business.
Once installed, we fully commission and test your system, connect it to your solar PV and EV charging where applicable, and provide guidance on using the Sigenergy Smart Energy App to monitor your power in real time.
With UKGEI, you get a seamless, professional installation — designed for long-term reliability, backed by world-class Sigenergy technology, and supported by a trusted local team.
