The supply meter still imports whatever the array is not covering, including nights, winter shortfalls and peaks above instantaneous output. The array is generation connected to the supply, not a replacement for it." } }, { "@type": "Question", "name": "Which parts of a business electricity bill can on-site solar reduce?", "acceptedAnswer": { "@type": "Answer", "text": "Solar typically reduces imported kilowatt-hours while the array is producing and the building is using power. That can affect the commodity element of a commercial supply contract and some charges calculated on imported volume. It does not remove the connection, and it does not automatically remove standing charges or capacity-related charges. The split on a given invoice is a contract fact, so it has to be read from the current bill rather than assumed as a national rule." } }, { "@type": "Question", "name": "Why is roof area a poor way to judge whether solar will cut imported electricity?", "acceptedAnswer": { "@type": "Answer", "text": "A generated kilowatt-hour helps the bill only if it lands while loads are running, within the connection agreement, and on a metering boundary that can show generation, import and export separately. Warehouses, factories and cold stores with daytime lighting and refrigeration usually match solar hours better than evening-peaked or weekend-empty sites. Offices and shops depend on occupancy and trading hours. Annual consumption is not a design load, and a layout based only on roof area will overstate on-site use and understate export." } }, { "@type": "Question", "name": "Is exported solar worth the same as electricity the business avoids importing?", "acceptedAnswer": { "@type": "Answer", "text": "It should not be assumed to be. Using a kilowatt-hour on site usually avoids more cost than selling it, because avoided import displaces the commodity and any volume-related charges on that unit. Export is a separate commercial arrangement and should not be copied from a small domestic export tariff. If the terms are not in writing, they are not part of the comparison. Storage can move surplus into later hours, but it is a further investment, and an export limit can mean surplus is not sold at all." } }, { "@type": "Question", "name": "What can limit a warehouse or office scheme before price is discussed?", "acceptedAnswer": { "@type": "Answer", "text": "Usable area, structural capacity, covering condition, access, switchgear and any distribution-network works can all cap the scheme. A large roof is not proof of a large useful system. Landlord consent matters too: a short lease, or a supply in the landlord's name, can mean the party who pays for the array is not the party whose invoice falls. Planning permission is not automatic for every non-domestic array, and business-rates treatment differs by nation, so neither an approval nor an exemption should be assumed. No national price, grant or tax relief is stated here, and any incentive or VAT treatment has to be checked against current official guidance." } }, { "@type": "Question", "name": "Can the local network change the size or start date of a commercial array?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. The distribution network operator has to agree how generation connects, including any export limit and any works on the network. Until that position is known, a layout based on roof area is not a project. Smaller connections are often notified under G98, and G99 is the common route once the plant sits outside that smaller class, but the boundary and study steps must be taken from the current documents for that operator. An export limit or a requirement for network works can change both the permissible capacity and when any saving can start." } }, { "@type": "Question", "name": "Is commercial solar maintenance-free, and does a performance guarantee mean lower bills?", "acceptedAnswer": { "@type": "Answer", "text": "No. Monitoring, cleaning, electrical inspection and inverter replacement are recurring items, and there is no national cost for that work. A performance guarantee is a contract, not a physical certainty. Shading, grid curtailment, outages and soiling are typical exclusions and should be read rather than treated as a savings promise. A module performance warranty is not a guarantee of bill savings, and whether a certification such as MCS is required depends on the contract, funder or export arrangement." } }, { "@type": "Question", "name": "How should a business compare on-site solar with staying fully on the grid?", "acceptedAnswer": { "@type": "Answer", "text": "Compare the cost of usable on-site energy over the period the business will actually use the system with the imported energy it displaces, after downtime, degradation and the charges solar cannot affect. Staying fully on the grid means every kilowatt-hour is imported. Adding solar means some daytime kilowatt-hours are generated on site, surplus is exported, stored or limited, and the connection remains. A green import tariff or corporate power purchase agreement changes the contractual source of grid electricity, but it does not create daytime coincidence at the site. Yields, prices and the share of a bill displaced stay unknown until the site and the contract are known." } } ], "about": { "@id": "https://kilowatts.uk/resources/commercial-solar-vs-grid-electricity-for-uk-businesses/#content" } }, { "@type": "WebPage", "@id": "https://kilowatts.uk/resources/commercial-solar-vs-grid-electricity-for-uk-businesses/#webpage", "url": "https://kilowatts.uk/resources/commercial-solar-vs-grid-electricity-for-uk-businesses/", "encoding": [ { "@type": "MediaObject", "encodingFormat": "text/markdown", "contentUrl": "https://kilowatts.uk/resources/commercial-solar-vs-grid-electricity-for-uk-businesses.md" }, { "@type": "MediaObject", "encodingFormat": "application/ld+json", "contentUrl": "https://kilowatts.uk/resources/commercial-solar-vs-grid-electricity-for-uk-businesses.schema" } ], "name": "Commercial solar vs grid electricity for UK businesses: UK", "headline": "Commercial solar vs grid electricity for UK businesses: UK", "description": "Commercial solar does not replace grid electricity for UK businesses.
