Quick answer
Cheshire West and Chester had 5,759 solar sites at the end of 2019 and 11,740 at the end of 2025, about 2.04 times as many. That is roughly 7.6 sites per 100 households. The count covers the whole borough and includes non-domestic sites, so it cannot give a Winsford figure on its own.
The figures
The Department for Energy Security and Net Zero publishes counts of renewable electricity sites for every local authority, including solar PV (regional renewable statistics). For Cheshire West and Chester, the borough that includes Winsford, the two ends of the period look like this:
| Point in time | Solar sites | Per 100 households |
|---|---|---|
| End of 2019 | 5,759 | 3.7 |
| End of 2025 | 11,740 | 7.6 |
| Change | +5,981 | +3.9 |
Over six years the count rose by about 5,981, roughly 997 a year on average, to about 2.04 times its 2019 level. Only the two end points are used here; the published tables give the years between, and the source link leads to them.
How the count is built
The statistics are assembled from the registers that installations pass through, such as MCS certification and the schemes that have paid for generation over the years, together with larger sites known to the government’s own records. Two things follow. First, recent years are revised as late registrations arrive, so the most recent figure tends to creep up in later editions. Second, systems that were never registered anywhere, such as some small plug-in kits or panels fitted without certification, are unlikely to appear at all. The count is therefore best read as a firm floor for registered solar in the borough rather than a census of every panel.
What counts as a site
Each installation is counted once, whatever its size. A house roof with ten panels and a ground-mounted array covering several fields each add one site. The count also includes non-domestic installations, on farms, businesses, schools, churches and public buildings, as well as homes. That has two consequences for reading it.
- It is not a count of homes with panels. Some of the 11,740 are not on homes at all, so the number of households with panels is lower than the site count.
- It says little about electricity produced. A handful of large sites can make more than thousands of roofs. The statistics publish installed capacity separately for that reason.
Sites per 100 households
Dividing the site count by the number of households gives a rough sense of how common solar has become. Against the government’s estimate of about 155,200 households in the borough, which is close to the Census 2021 figure of 155,154 (Census 2021), the count works out at about 3.7 sites per 100 households at the end of 2019 and about 7.6 at the end of 2025. Because non-domestic sites are included, the share of households with their own panels will be somewhat lower than that. Even so, the direction is clear: solar went from unusual to familiar in six years.
What the borough figure cannot say about Winsford
There is no published count for Winsford alone, and this guide does not try to estimate one. The town differs from the borough in ways that would matter. Its expansion as an overspill town in the 1960s, recorded in the council’s planning paper (Places background paper, 2024), left it with more social renting than the borough as a whole: 28.2% of households in Over & Verdin and 23.9% in Wharton, against 14.6% across Cheshire West and Chester. In those homes panels arrive through the landlord’s programme, not the household’s decision. In Gravel, where 74.7% of households own their home, the position is closer to the borough’s.
So the borough’s growth tells a Winsford household that panels have become common nearby, not how common they are on its own street. The tenure picture, ward by ward, is on who decides about solar, and house types are on Winsford homes by ward.
The council’s group-buy in context
Some of the recent growth came through Switch Together Solar, the group-buying scheme the council runs with Cheshire East and Warrington. By the council’s figures, 473 people in the borough had solar fitted through the 2023 to 2025 rounds. Its most recent window for registering shut on 25 September 2026 (council page). The scheme counts people, while the statistics count sites, so the two numbers measure different things and should not be divided one by the other. Both point the same way. How the scheme works is on grants and schemes.
What the figures do not explain
A count of sites shows that more panels went up, not why. It does not separate homes from other buildings, owners from landlords, or new systems from replacements, and it cannot say what people paid or what their roofs make. This guide therefore draws no conclusion about causes from the figures. For what a roof in Winsford makes, see what panels make in Winsford; for what people paid in 2025/26, see solar costs in Winsford.
Reading a doubling
A count that doubles sounds dramatic, and in one sense it is: roughly as many solar sites were added in the borough between 2019 and 2025 as existed in total at the start. But the starting point matters. At the end of 2019 there were about 3.7 sites per 100 households, so even after doubling the large majority of households in the borough still had no panels of their own. The figures say nothing about what happens next. They are a record of what was installed and registered, not a forecast, and this guide does not project them forward.
Using the figures sensibly
The take-up figures are context, not a reason to buy. They are useful in three ways. They show that solar is now ordinary enough that firms, lenders, solicitors and surveyors deal with it routinely. They mean that buyers will meet panels more often on houses for sale, which is why buying a Winsford home with solar exists. And for tenants of social landlords they are a reminder that panels are spreading through the borough’s housing, which is a fair point to make when asking a landlord about its plans; housing association tenants lists the questions.
Panels on nearby roofs
Growth on this scale means many Winsford households can now see panels on houses like their own. That is useful in a practical way. A neighbour’s array on a matching semi shows which face the firms chose and roughly how many panels fitted, and a neighbour willing to talk can say how the job went and whether the papers arrived. It is not evidence about any particular firm, and a roof that looks the same may differ in shade, structure or wiring. Treat what you see as a reason to ask better questions at the survey, not as a substitute for one.
Where the data comes from
The site counts and household estimate come from the DESNZ regional renewable statistics; the household comparison and tenure figures from Census 2021; the scheme figure from the council.
