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.

Solar is no longer just a panel-price question. In 2026, the real decision is about tariffs, export rules, storage, paperwork and a quote you can trust.
Solar panel installation process UKA good solar installation process is mostly paperwork and planning before the panels ever arrive on the roof.
Solar panels without a batteryA battery is optional, not compulsory. Many UK homes should model solar-only first before adding the extra storage cost.

SEG is the route most UK households use to get paid for exported solar electricity. The rule is simple, but the paperwork and tariff choices matter.
MCS certificates for solar panelsMCS isn't just a logo on a quote. For many households it is the simplest proof route for SEG eligibility and system paperwork.
DNO, G98 and G99 for home solarThe DNO question is about how your system connects to the local electricity network. It isn't the same as your panel size.
VAT on solar panels and batteriesInstalled solar panels and certain energy-saving materials are temporarily zero-rated for VAT, but the detail matters.
Planning permission for solar panelsMost house roof installs are straightforward, but planning rules aren't identical across the UK and exceptions matter.
Solar panel grants and support in the UKThere isn't a universal solar grant for everyone, but VAT relief, SEG payments and targeted schemes can still change the numbers.
How to compare solar quotesThe cheapest quote isn't always the best. The best quote is the one where the system design, assumptions and paperwork all stack up.
Roof suitability and shadingA good roof matters more than a glossy panel brochure. Shade and roof condition can change the economics quickly.
Self-consumption and solar savingsSelf-consumption is often the quiet number that decides whether a solar estimate looks ordinary or excellent.
Is a solar battery worth it?A battery can be useful, but it's not automatically a faster payback. The answer depends on cost, routine and tariff.
Export tariffs, batteries and time-of-use ratesExport tariffs can be simple or surprisingly fiddly. Batteries make the small print more important.
Solar generation by system sizeSystem size is only the starting point. Annual generation depends on the roof and location as much as the headline kWp.
Solar panels with an EV or heat pumpEVs and heat pumps can improve the solar case, but only when the timing and controls make sense.
Solar panel maintenance and warrantiesSolar is low-maintenance, not no-maintenance. Warranties and monitoring are what keep small problems from becoming expensive.
Solar panel cost calculatorA solar cost estimate is only useful if it includes the whole installed job and separates solar-only cost from battery extras.
How to calculate solar savingsSolar savings are not one magic number. You get a better estimate by valuing self-used electricity and exported electricity separately.
Solar battery payback calculatorThe right battery calculation compares the extra annual benefit with the extra battery cost. Blended payback can hide the real answer.
Peak shaving with solar batteriesPeak shaving sounds technical, but for a household it usually means using storage to avoid expensive grid electricity at busy times.
Solar panel price comparison UKA fair price comparison looks beyond the headline quote. You need to compare system size, annual kWh, paperwork and aftercare.
Solar cost per kWh explainedCost per kWh can be useful, but it is easy to misuse. The household value of solar depends on both bill savings and export income.
