Sigenergy Solar Installation in Crewe: 11.5kWp Solar & 20kWh Battery System Completed in Weston

Underwood Electrical has completed a high‑performance Sigenergy solar installation in Crewe, delivering a full solar PV and battery storage solution for a homeowner in Weston. The project combines a powerful 11.5kWp solar array with 20kWh of advanced Sigenergy battery storage, enabling the property to generate, store and manage its own renewable electricity more efficiently than ever.

With energy prices continuing to fluctuate, more homeowners are turning to solar and battery systems to reduce reliance on the grid, improve long‑term energy security and take control of their energy usage. This installation demonstrates how modern solar technology and intelligent energy management can work together to maximise self‑consumption and deliver long‑term savings.

Project Overview

This renewable energy system features:

• • 25 × 460W Jinko all‑black solar panels
• • 11.5kWp total installed solar capacity
• • Sigenergy 10kW Energy Controller
• • 2 × 10kWh Sigenergy batteries (20kWh total storage)
• • Full bird‑protection system

The combination of high‑efficiency Jinko panels and Sigenergy’s intelligent battery technology allows the homeowner to capture excess solar generation during the day and use it later in the evening when demand is higher. This significantly reduces imported electricity and increases the value of every unit of solar energy produced.

Solar Array & Bird Protection

The all‑black Jinko panels provide a sleek, modern appearance while delivering excellent performance throughout the year. The array was carefully designed to maximise available roof space and maintain an attractive finish that complements the property.

A full bird‑protection system was installed to prevent nesting beneath the panels — a common issue that can cause debris build‑up, reduced airflow and long‑term maintenance problems. Drone photography highlights the scale of the installation and how seamlessly the array integrates with the existing roof structure.

Why Battery Storage Makes a Difference

Battery storage is now one of the most valuable additions to any solar installation. Without it, excess daytime generation is typically exported back to the grid for a relatively low return. With a 20kWh Sigenergy battery system, the homeowner can store a substantial amount of renewable electricity and use it later when it’s most beneficial.

Sigenergy’s intelligent energy management software continuously monitors:

• • Solar generation
• • Household consumption
• • Battery charge levels

This ensures the system operates at peak efficiency throughout the day, maximising self‑consumption and reducing reliance on imported electricity.

Clean & Professional Garage Installation

The Sigenergy battery units and energy controller were installed neatly within the garage, creating a clean, accessible and professional setup. Underwood Electrical’s attention to detail ensures the system is easy to maintain while providing a tidy, modern finish. The Sigenergy equipment offers advanced functionality alongside a sleek design that fits seamlessly into the space.

Benefits of Solar & Battery Storage

Homeowners across Cheshire and the surrounding areas are increasingly investing in renewable energy systems due to the wide range of benefits:

• • Lower electricity bills
• • Greater energy independence
• • Protection against future price rises
• • Reduced carbon footprint
• • Improved long‑term return on investment

By combining solar generation with battery storage, homeowners can make far better use of the electricity they produce — increasing efficiency and maximising financial savings.
