Solar panels convert sunlight into electricity. This power can be used in your home, stored in a battery, or sent to the grid for a Smart Export Guarantee (SEG) payment.

A battery storage system stores excess solar energy for use when the sun isn't shining. It helps reduce your reliance on the grid and saves more on energy bills.

Prices vary depending on system size, components, and installation specifics. We offer systems starting from £4,995 for a complete setup. Contact us for a free, no-obligation quote!

Most residential solar PV systems are installed in 1-2 days, depending on complexity.

Yes! Solar panels still generate electricity in diffused sunlight, but performance is lower compared to direct sunlight.

Yes! We offer retrofit battery storage solutions to upgrade your existing solar PV system.

Most high-quality panels have a 25+ year lifespan, with warranties covering 80-90% efficiency over that period.

In most cases, no planning permission is required for residential solar installations unless you live in a listed building or conservation area.

We work with various leading brands such as:
• JA Solar
• Jinko

We install:
• Solax
• Sunsynk
• Hanchu
• Solaredge

Most panels have efficiency ratings between 18-22%, meaning they convert that percentage of sunlight into usable electricity.

Panels are durable, but if one fails, we can replace it under warranty or repair the system.

We offer:
• Solax
• Sunsynk
• Hanchu
• Solaredge

Battery sizes range from 2kWh to 20kWh+, depending on your needs. We'll help you choose the right size.

Most batteries last 10-15 years, with warranties covering 6,000+ charge cycles.

It's possible, but in the UK, most homes still need some grid connection for backup during winter months.

Yes! With an off-peak energy tariff, you can charge your battery overnight when electricity is cheaper and use it during peak hours.

Savings depend on system size and usage. A typical 4kW system can save £500+ per year on electricity bills.

Yes! The Smart Export Guarantee (SEG) allows you to earn money for exporting surplus electricity.

Currently, there are no direct solar panel grants, but VAT is 0% on solar & battery installations until 2027.

Most systems pay for themselves in 5-10 years, depending on electricity savings and SEG payments.

Yes! We offer flexible finance options to spread the cost of your installation.

No! Our expert installers ensure secure mounting without any damage to your roof structure.

Technically, yes, but it's not cost-effective. A solar system increases your property value, making it a great selling point!

• Solar panels – 25-year performance warranty
• Inverters – 5-12 years depending on brand
• Batteries – 10-year warranty

We offer ongoing support and maintenance. If anything goes wrong, we'll help troubleshoot and fix the issue.

All our installations include a smart app for real-time energy monitoring on your phone or computer.

Most domestic solar panel installations fall under Permitted Development Rights (PDR), meaning you don't need planning permission. However, you might need approval if your property is listed or in a conservation area, or you are installing ground-mounted panels above 9m² or taller than 4m.

A G98 application is required for small-scale solar installations (≤3.68kW per phase or 11.04kW for three-phase systems) connecting to the grid. It is a simplified process, and in most cases, it is handled after installation as a "Connect and Notify" procedure.

A G99 application is needed for larger systems above 3.68kW per phase (or 11.04kW for three-phase systems). Unlike G98, it must be submitted before installation to get approval from the Distribution Network Operator (DNO).

After your solar installation, you should receive:
✅ DNO Notification Approval (for G98 systems) or Final Connection Approval (for G99 systems)
✅ MCS (Microgeneration Certification Scheme) Certificate – Required to register for export tariffs like the Smart Export Guarantee (SEG)
✅ Electrical Installation Certificate (EIC) – Confirms that the installation complies with UK electrical regulations
✅ DNO Letter of Acceptance – Confirms the system is approved and connected to the grid
✅ Product Warranties & User Manuals – Covering your solar panels, inverter, and battery (if applicable)

The Smart Export Guarantee (SEG) allows you to get paid for surplus electricity you export to the grid. To apply, you will need your MCS certificate, your DNO approval confirmation, and a smart meter that records export readings.

Yes, as solar panels are a structural addition to your home, you should inform your insurance provider to ensure coverage.
