Practical UK solar guides
Clear, source-backed guides for the parts of solar that actually trip people up: export tariffs, DNO paperwork, MCS certificates, VAT, planning, batteries and payback.
Editorial standard
Current figures, cautious examples
The guides use official sources where possible, separate regulations from buying advice, and keep calculator examples conservative. When Ofgem rates, Energy Saving Trust figures, VAT rules or SEG guidance change, affected pages are reviewed rather than silently refreshed.
