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.

Start with these guides
Solar can be a strong household upgrade, but only when the roof, quote, generation estimate, tariff and export setup all work together.
5 times solar panels might not be worth it yetSolar is a good fit for many homes, but not all of them. A weak roof, poor quote or unrealistic battery claim can turn a decent idea into a bad buy.
Is solar worth it with a battery? 8 checksA battery can make solar feel more useful, but it needs its own calculation. Start with the solar-only case, then judge the battery uplift.
Energy Saving Trust solar calculator guideEnergy Saving Trust figures are a useful benchmark, but your own savings estimate still needs your roof, quote and tariffs.
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.

Export 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.
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 panels without a batteryA battery is optional, not compulsory. Many UK homes should model solar-only first before adding the extra storage cost.
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.
