Government Incentives and Support
The UK government continues to support solar adoption through various schemes and incentives.
Smart Export Guarantee (SEG)
The SEG scheme requires licensed electricity suppliers to pay for excess solar electricity exported to the grid.
- Eligibility: Systems up to 5MW capacity
- Payment rates: Vary by supplier (typically 3-7p per kWh)
- Duration: Ongoing payments for exported electricity
- Requirements: MCS certification mandatory
VAT Reduction
Since April 2022, VAT on solar panels has been reduced to 0% for residential installations, making solar more affordable than ever.
Green Homes Grant (Where Available)
Some local authorities still offer grants and financing options for renewable energy installations. Check with your local council for available schemes.
Planning Permission and Building Regulations
Most residential solar installations in the UK fall under permitted development rights, but it's important to understand the requirements.
Permitted Development Criteria:
- Panels don't protrude more than 200mm from roof surface
- No panels on walls facing highways
- Removal restores original appearance
- No panels on listed buildings without consent
- Conservation area restrictions may apply
Building Regulations Compliance:
Solar installations must comply with building regulations, particularly regarding structural integrity and electrical safety. A qualified installer will ensure compliance.
Choosing the Right Solar Installer
Selecting a reputable installer is crucial for a successful solar project. Here's what to look for:
Essential Qualifications:
- MCS Certification: Microgeneration Certification Scheme
- Electrical qualifications: Part P compliance
- Insurance coverage: Public liability and professional indemnity
- Industry memberships: Solar Trade Association, RECC
- Local reputation: Established track record in your area
Questions to Ask Potential Installers:
- Are you MCS certified and can you provide certificate number?
- What warranties do you offer on equipment and installation?
- Can you provide local references from recent customers?
- What is your process for obtaining necessary permits?
- How do you handle system monitoring and maintenance?
- What financing options are available?
- What happens if panels need repair or replacement?
System Sizing and Energy Assessment
Proper system sizing ensures optimal performance and return on investment.
Factors in System Sizing:
- Annual electricity consumption: Review past 12 months of bills
- Roof space and orientation: South-facing roofs optimal
- Shading analysis: Impact of trees, buildings, chimneys
- Future electricity needs: Electric vehicles, heat pumps
- Budget considerations: Balance system size with investment
Roof Orientation and Performance:
South-facing
100% efficiency - Optimal performance
East/West-facing
85-90% efficiency - Very good performance
North-facing
60-70% efficiency - Generally not recommended
Financing Options for Solar Panels
Multiple financing options make solar accessible to homeowners with different financial situations.
Cash Purchase
