Average System Cost £4,500-£5,500 £5,500-£7,000 £7,000-£8,500 £8,500-£11,000
Number of panels 10 14 18 22
Annual Savings £400-£500 £500-£600 £600-£750 £700-£900
Lifetime Savings (30 yrs) £15,000 £18,000 £22,500 £27,000
Expected Payback Period 9-11 years 8-10 years 8-9 years 7-8 years

Factors Affecting Payback:

Sunlight availability in the region:

The more sunny days, the more energy generated and saved.

Energy tariffs:

Rising electricity prices can shorten the payback period as the value of saved energy increases.

Government subsidies and incentives:

In the UK, programs like SEG can accelerate payback by providing additional income for every kilowatt-hour returned to the grid.

On-grid Solar Panel System

A home solar panel system harnesses sunlight and converts it into electricity to power your home, reduce energy bills and provide backup during outages. This integrated system provides sustainable, reliable energy while reducing utility costs, offering a simple way to make your home more eco-friendly and energy-efficient.

Solar Panels:

Mounted on the roof, these panels capture sunlight and convert it into direct current (DC) electricity.

Inverter:

The inverter changes DC electricity from the panels into alternating current (AC), the type of electricity your home’s appliances and lights use.

Battery Storage:

Excess energy is stored in batteries, so you have power available at night or during cloudy weather, making your home less dependent on the utility grid.

Meter:

The meter tracks your energy usage and any extra electricity sent back to the grid. Many homes receive credits for this surplus energy through a net metering program.

Utility Grid Connection:

When solar energy production is low, your home automatically pulls power from the grid, ensuring you always have electricity available.

On-Grid Solar System

Off-grid Solar Panel System

An off-grid solar panel system operates independently of the utility grid, making it ideal for remote locations or homes seeking complete energy independence. Unlike a grid-tied system, an off-grid setup relies entirely on solar, battery and generator power, offering true energy independence and self-sufficiency.

Solar Panels:

Mounted on the roof, these panels capture sunlight and convert it into direct current (DC) electricity.

Inverter:

The inverter changes DC electricity from the panels into alternating current (AC), the type of electricity your home’s appliances and lights use.

Battery Storage:

Batteries store excess energy generated during the day for use at night or during cloudy periods, providing a reliable, round-the-clock power supply.

Meter:

The meter helps monitor energy production and usage, allowing you to optimize battery levels and overall system performance.

Backup Generator:

If solar and battery power run low, a backup generator kicks in, ensuring an uninterrupted power supply during extended periods of low sunlight.

Solar Panel Installation Process

Initial Consultation

We start with a consultation to understand your energy needs, location and goals, providing an initial overview of the system that best suits your requirements. Typically takes 1 day.

1

Site Assessment

After initial contact, our team will schedule a site visit within a day or two to assess the roof condition, sun exposure and location for solar panels, batteries and other components, ensuring optimal system performance. Typically takes 1-2 days.

2

System Design & Proposal

Based on the assessment, we design a custom solar solution, including equipment recommendations, estimated energy savings and a detailed project proposal. Takes about 4-5 days.

3

Permission & Approvals

We handle all required permits and paperwork, ensuring the installation complies with local regulations and utility requirements. The timeline depending on local regulations and utility provider processing times.

4

Installation & Testing

Certified technicians install and thoroughly test the entire system, including panels, inverters and batteries, ensuring safety and efficiency. Installation itself usually takes 1-3 days, depending on system size and site accessibility.

5

System Handover & Support

The handover session typically takes 1-2 hours. After installation, we provide ongoing support, offering routine maintenance, panel cleaning and monitoring to ensure long-term efficiency and optimal performance.

Off-Grid 5.7kW Solar Power System for Hotel

We installed an off-grid 5.7kW solar power system at a remote hotel in northern Scotland, expanding the solar array from 7 to 16 high-efficiency panels and adding a second 6kW SMA Solar Inverter alongside BYD lithium batteries (20kWh) for extended energy storage. The system, equipped with MPPT charge controllers, generates up to 22 kWh per day, providing up to 48 hours of autonomy and reducing diesel generator usage by approximately 65% annually, cutting fuel costs and lowering CO₂ emissions by 2,000 kg per year.

Residential Wind Turbine Project for Outdoor Lighting

We installed a compact horizontal-axis wind turbine (300W) on a 2-meter pole in the yard of a private home to power outdoor LED lighting. The system includes a 12V 100Ah lithium battery with an MPPT charge controller and a 300W pure sine wave inverter, ensuring stable energy supply. The turbine, optimized for average wind speeds of 4.8 m/s, generates approximately 1.5 kWh per day, providing reliable night-time illumination for garden pathways and patio areas. The energy stored in the battery offers up to 20 hours of lighting autonomy. This project highlights an eco-friendly, cost-effective solution for residential outdoor lighting using renewable wind energy.

Frequently Asked Questions

How much energy can a residential solar power system generate?
chevron icon

The amount of energy generated depends on the system size, location and sunlight availability. On average, a residential solar system can produce between 3,000 and 10,000 kWh per year, which is often enough to cover most of a household's energy needs.

Can a wind turbine power my home?
chevron icon

Yes! A properly sized residential wind turbine can generate enough electricity to meet or supplement your home’s energy demands, especially in areas with consistent wind speeds above 5 meters per second (11 mph).

What happens during cloudy days or low wind conditions?
chevron icon

Solar panels and wind turbines will generate less power during cloudy or low-wind conditions. However, battery storage or hybrid systems can provide backup power, ensuring consistent energy supply even when conditions are not ideal.

How long does the installation process take?
chevron icon

Installation typically takes between 1 to 5 days, depending on the system size and complexity. The full process, including permitting and inspections, may take a few weeks from start to finish.

Is an off-grid system reliable in remote locations?
chevron icon

Absolutely. Off-grid systems are specifically designed for remote areas and include batteries and energy management systems to ensure a stable power supply 24/7 — even without access to the main electricity grid.

How much can I save on energy bills?
chevron icon

Savings depend on your energy consumption and system size. Many homeowners reduce their energy bills by 50–90%. Over time, the system often pays for itself through savings and possible government incentives.

Do I need planning permission for solar panels or a wind turbine?
chevron icon

In many cases, small-scale solar panels and wind turbines fall under permitted development. However, this can vary based on your location and the size of the installation. It's best to check local regulations or let us handle the planning requirements for you.

How long do the solar panels and batteries last?
chevron icon

Solar panels typically last 25–30 years with minimal efficiency loss. Batteries generally last 10–15 years, depending on usage and type. Our systems use high-quality components for maximum lifespan and reliability.

Do you offer maintenance and support?
chevron icon

Yes, we offer full lifecycle support including regular maintenance, system monitoring and responsive customer service to ensure your system runs efficiently for years to come.
