We fit solar and battery storage on Gloucester homes and businesses through the year, so you deal with an installer that genuinely works in the area.
Four things decide it. Most homes pass on all four, and the one people worry about most is rarely the problem.
The question we are asked most, and the one people get wrong. Due south is best, but in Gloucester an east-facing roof still returns about 81% of a south-facing one and west about 80%. South-east and south-west are within 6%. A roof that is not south facing is usually still worth doing.
A 4kW system needs roughly 9 panels and about 18 square metres of usable roof. Panels can be split across two faces where one is not big enough, which is common on terraces and on houses with a rear extension.
A chimney, a dormer or a neighbour's tree costs more than people expect, because shade on one panel used to drag down the whole string. Panel-level optimisers or microinverters fix that, and the survey is where we work out whether you need them.
We check age, covering and structure before anything else. If a roof needs work in the next few years, it is cheaper to do it before the panels go on, and we will say so rather than fit around it.
Our residential solar panel installation services in Gloucester are designed to help homeowners harness the power of the sun and reduce their carbon footprint.
Businesses across Gloucester, from offices and warehouses to retail units, cut running costs and carbon with commercial solar. We handle solar panel installation Gloucester companies can rely on, from the design and DNO paperwork through to commissioning, sized to your roof and demand.
Store the power you generate and charge your car on sunshine. We fit home and commercial battery storage, a matched inverter and a home EV charger across Gloucester.
No, and the gap is smaller than most people expect. In the UK the sun sits in the southern sky, which is why a south-facing roof is the 100% case and every other direction is measured against it. Modelled for Gloucester.
Each figure is that orientation’s own annual output in Gloucester. The compass turns with the house, so the reading is for the way it is facing. Tap any of the five to hold it.
PVGIS (EU Joint Research Centre), 4kW system at a 35 degree pitch. An east or west facing roof in Gloucester still returns around four fifths of a south-facing one, which is usually the difference between worth doing and not.
Start with the one figure you already know off your bill. What comes back is what we actually quote a home that uses that much, and what it would make in Gloucester.
5,000kWh
It starts at 5,000 kWh, the middle of the 1,504 quotes we hold a usage figure for. The mark shows GL: a median of 5,749 kWh across 22 quotes.
What we typically quote a home like that
13panels6.2 kW
Modelled to make 5,937 kWh a year in Gloucester, against the 5,000 kWh you use. Over a year that is more than the house gets through, though not at the hours it gets through it.
| System | Panels | Generation a year | Typically suits |
|---|---|---|---|
| 3kWp | 6 panels | 2,855 kWh | Smaller homes, or a roof with one usable face |
| 4kWp | 8 panels | 3,806 kWh | Around the size we fit most often |
| 6kWp | 13 panels | 5,709 kWh | Larger homes, or a household with an EV |
| 8kWp | 17 panels | 7,612 kWh | High usage, an EV and a heat pump |
Generation from PVGIS (EU Joint Research Centre), 35 degree pitch, due south. The size we suggest is the median we quote homes in your usage band across 1,450 quotes, not a rule of thumb: real quoting is much flatter than usage, because roof space caps the top of it. Panels at 480W, the AIKO module in most of our quotes; the 470W DMEGC needs one more for the same output. The table models whole kWp sizes, so its panel counts are the nearest module. What you save depends on your tariff and how much you use during daylight, which is what the free assessment works out. We will not put a figure on it before we have seen your bill.

However, it’s recommended to check with your local planning authority or consult with a professional installer to ensure compliance with regulations.
Solar panels installed in Gloucester typically have a lifespan of 25 to 30 years or more. While the initial investment in solar panels is significant, their long lifespan ensures that they provide a reliable and sustainable source of energy for decades to come.
The efficiency of solar panels in Gloucester depends on various factors, including the orientation of the panels, shading, and weather conditions. On average, solar panels installed in Gloucester can have efficiency ratings between 15% to 22%, meaning they can convert 15% to 22% of sunlight into usable electricity. Across our Gloucester installs, 4kW is the system size we fit most.
Yes, there are several incentives available for solar panel installations in Gloucester, including the Smart Export Guarantee (SEG) and the Renewable Heat Incentive (RHI). These schemes offer financial incentives and payments for generating renewable energy, helping to offset the cost of solar panel installations.
Yes, solar panels can still be installed on roofs that are not south-facing in Gloucester. While south-facing roofs typically receive the most sunlight throughout the day, solar panels can still generate significant electricity on east-facing or west-facing roofs. A professional installer can assess the orientation and suitability of your roof for solar panel installation.
The payback period for solar panel installations in Gloucester can vary depending on factors such as the cost of the system, energy savings, and available incentives. Payback depends on system size and how much of the electricity you use during daylight. As a guide, most home systems in Gloucester typically pay back in 8 to 12 years, and larger commercial systems are usually faster. Our calculator gives you a figure for your own roof in about a minute. With 11 installs completed around Gloucester, we base your estimate on real nearby jobs, not a generic average.

It depends on your roof and how much electricity you use, not on the town. Modelled by PVGIS, a 4kW system in Gloucester returns about 3,806 kWh a year, and the median system we are asked to quote in the GL postcode area is 8.16 kW. Whether that adds up for you comes down to your tariff and how much you use during daylight, which is what the free assessment works out. We will not put a figure on it before we have seen your bill.
About 3,806 kWh a year from a 4kW system, modelled for Gloucester by PVGIS (the EU Joint Research Centre) at a 35 degree pitch facing south. It is not spread evenly: roughly 466 kWh in May against 127 kWh in December. Your own figure depends on which way the roof faces, its pitch and any shading, which is what the survey measures.
No. They run on daylight rather than heat or direct sun, so they generate on overcast days too. Gloucester shows it plainly: the same 4kW system still returns about 127 kWh through December, the dullest month of the year here.
Yes. We survey and install across the GL postcodes, including GL51, GL50, GL2, GL20, GL52, GL4, GL1 and GL3. If your postcode is not in that list it is still worth asking, because the list is drawn from where we actually work rather than a radius drawn on a map.
Yes. Work is carried out under our own MCS registration. That matters beyond the badge: MCS is the UK government-recognised standard for solar installations and it is what the Smart Export Guarantee requires, so without it you cannot be paid for what you export. You can check any installer, us included, by name at mcscertified.com before you commit.
Check three things before you compare prices. That the installer is MCS certified, because the Smart Export Guarantee depends on it. That the quote is itemised, so you can see the panel, the inverter and the battery separately instead of one number. And that the workmanship warranty is written down, with who honours it named. It is also worth asking who files your DNO paperwork, because that is the step most often left to the customer.
They cut what you buy from the grid, and how much depends on your tariff, when you use power and whether you add a battery. In the GL postcode area 94% of the systems we are asked to quote include storage, which is what lifts the share of your own generation you actually use. We will not put a saving figure on it before we have seen your bill.
Solar panels turn daylight into electricity: the panels generate DC power, an inverter converts it to the AC your home uses, and anything you do not use can charge a battery or export to the grid. They run on daylight rather than direct heat, so they work all year round. Every system we fit in Gloucester is sized and wired to your own roof and usage.
It depends on how much electricity you use, your roof space and whether you add a battery, not your postcode. The system we fit most around Gloucester is about 4kW; after a free assessment we size it to your actual bills so you are not over- or under-panelled.
Yes. Solar panels run on daylight rather than heat, so they still generate on overcast days and through winter, just less than at the height of summer. For Gloucester that is about 127 kWh in December against 466 kWh in May from the same 4kW system, which is why we size systems around your annual usage rather than a single sunny day.
As well as cutting your bills, solar and battery systems can make a home more appealing to buyers, and several studies link them to a modest uplift in value. In Gloucester, the day-to-day saving on your electricity is usually the bigger draw, with any resale benefit on top.
