Solar PV Installation
Solar installation involves the setup of photovoltaic (PV) panels on your property to harness energy from the sun and convert it into usable electricity. This process typically begins with a detailed assessment of your energy needs, roof space, and orientation to design a system that maximizes efficiency and output.
Once the system is tailored to your property, skilled installers mount the solar panels, connect them to an inverter, and integrate them with your home’s electrical system. Whether it's a domestic rooftop install or a large commercial array, professional installation ensures long-term safety, compliance with regulations, and optimal performance.
Battery Storage Solutions
Battery storage solutions allow you to store the excess electricity generated by your solar panels during the day, so you can use it later when the sun isn’t shining—such as in the evening or during a power outage. Instead of sending unused solar energy back to the grid, battery systems let you keep that energy on-site, increasing your self-consumption and reducing your reliance on external power sources. This makes your solar setup more efficient and helps you get the most value out of your investment, especially during periods of high electricity rates.
Modern battery storage systems are compact, smart, and highly reliable. They can be installed alongside a new solar PV system or retrofitted to an existing one. Many models offer app-based monitoring, allowing you to track charge levels, usage patterns, and system health in real-time.
EV Charger Installations
EV charger installation allows you to conveniently and efficiently charge your electric vehicle at home or at your business premises. By having a dedicated EV charger installed, you can reduce your reliance on public charging stations and enjoy faster, safer charging compared to using a standard wall socket.
Professional EV charger installation ensures that your unit is properly integrated with your electrical system and meets all safety regulations. Whether you drive a Tesla, Nissan, Kia, VW, or any other electric vehicle, our installers will recommend a charger compatible with your car and tailored to your charging needs.
Maintenance & Care
Solar panel maintenance is essential to keeping your system operating at peak efficiency and ensuring long-term performance. While solar panels are generally low maintenance with no moving parts, they can accumulate dirt, dust, leaves, and bird droppings over time, which can reduce energy output. Regular cleaning and visual inspections help to keep your panels clear and functioning efficiently.
Professional maintenance services go beyond surface cleaning—they include thorough system checks, inverter diagnostics, and performance monitoring to catch any issues early. Technicians can identify faults, drops in output, or signs of wear before they become costly problems.

What is included in your Solar PV Installation?
Step 1: Site Assessment & Design
Tailored Planning
We begin with a no-obligation consultation where we’ll assess your roof, your electricity usage, and your energy goals. This can be done in person or remotely using satellite imaging. You’ll receive honest advice and zero pushy sales tactics.
Step 2: System design & Quotation
Seamless Setup
We create a bespoke solar PV system tailored to your property. Our detailed proposal includes a panel layout, estimated annual generation, cost savings forecast, ROI estimates, and a fixed-price quote. We’ll also explain your payback period and answer any technical questions.
Step 3: Professional Installation
Long Term Performance
Once you’re ready, we’ll schedule the installation at a time that suits you. Our team will install all panels, wiring, inverters, batteries, and monitoring systems, plus we handle scaffolding and final electrical checks. Most residential installs take just 1–2 days.
Step 4: Activation & Handover
Quality Installation
Once complete, we’ll commission the system, walk you through the monitoring app, and register your install with MCS and your energy provider. You’ll start generating clean electricity right away—and saving on your bills from day one.
What are the benefits?
Cost Savings
You generate your own electricity from sunlight, which means you rely less on power from the grid. This directly reduces your monthly energy bills, allowing you to keep more money in your pocket.
Energy Independence
Solar power gives you more control over your energy supply. By producing your own electricity, you become less vulnerable to fluctuations in energy prices and grid outages.
Zero Emissions
Solar energy is a clean and renewable power source that produces no greenhouse gas emissions while generating electricity. It’s a powerful way to contribute to a sustainable energy future.
Increased Value
Potential buyers recognise the long-term energy savings and environmental benefits that come with a solar installation, making your property more attractive.
Government Incentives
Many governments offer financial incentives such as tax credits, rebates, or grants to encourage solar adoption. These schemes help offset the upfront cost of installation, making solar energy more affordable and accessible.
Stored Energy
Pairing your solar panels with a battery storage system lets you save excess energy generated during the day for use at night or during power outages. This increases your energy independence and allows you to make the most of your solar investment by using stored solar power even when the sun isn’t shining.
Low Maintenance
With no moving parts, they are less prone to breakdowns and typically come with long warranties, often lasting 25 years or more. Routine cleaning and occasional inspections ensure optimal performance over time.
Unobtrusive
Solar panels operate silently and blend seamlessly onto rooftops or open spaces without disrupting daily life. Unlike generators or other energy systems, solar produces no noise pollution, making it an ideal energy solution for residential and commercial properties alike.

How does the solar panel installation process work?
The solar panel installation process begins with a thorough assessment of your property, including roof condition, orientation, shading, and your typical energy usage. A professional installer will design a system tailored to your needs to maximize energy production. After design approval, the installation team will securely mount the panels on your roof or another suitable location, connect them to an inverter (which converts sunlight into usable electricity), and integrate the system with your home’s electrical supply. The entire process usually takes a few days, depending on the system size and complexity.
Once installed, the system undergoes testing to ensure everything operates correctly and safely. Your installer will also guide you through monitoring tools to track your energy production. After final inspections and approvals, your solar system will be ready to start generating clean electricity, reducing your energy bills and carbon footprint immediately.
