Why Switch to Solar After the July 2026 Energy Price Cap Increase?

Estimated reading time: 9 minutes

On 1 July 2026, Ofgem raised the energy price cap by 13%, increasing the typical annual dual-fuel bill for a household paying by Direct Debit from £1,641 to £1,862 — a rise of approximately £221 per year. The average electricity unit rate moved from 24.67p to 26.11p per kWh, with a standing charge of around 57.19p per day.

For homeowners across West Sussex, Surrey and Hampshire who have been thinking about solar panels but have not yet taken the next step, this is a useful moment to look more carefully at the long-term picture. Not because solar is a quick fix, but because the July 2026 increase is a reminder of something that has been true for several years: household electricity costs remain closely linked to wholesale energy markets and international events — and they can move sharply.

This article explains how solar PV and battery storage work, what they can realistically offer, and why summer is a good time to start the conversation.

What the July 2026 Price Cap Actually Means

Before considering how solar panels might help, it is worth being clear about what the price cap does and does not do.

The £1,862 annual bill figure is not a maximum amount any household can be charged. It is an illustration based on typical energy consumption for a dual-fuel household paying by Direct Debit. The cap limits the unit rate and standing charge that suppliers can apply — not the total bill. If your household uses more electricity than average, your bill will be higher. The current cap period runs from 1 July to 30 September 2026, after which Ofgem will review the figures again.

The July 2026 increase demonstrates how exposed households remain to movements in global energy markets. Price caps are reviewed every three months and can rise or fall depending on wholesale conditions. This uncertainty is one of the reasons a growing number of homeowners across Horsham, Crawley, Worthing, Chichester and the wider South East are looking at ways to generate a proportion of their own electricity at home.

How Solar Panels Can Help Reduce Your Electricity Costs

Solar panels generate electricity from daylight. Every kilowatt-hour (kWh) generated and used directly within your home is one less kilowatt-hour you need to purchase from your supplier. At the current import rate of 26.11p per kWh under the July 2026 cap, each unit generated and consumed at home rather than imported from the grid has a direct cost benefit.

Over the course of a year, a domestic solar installation can generate a meaningful proportion of a household's electricity requirement. How much depends on a range of factors:

• Roof orientation, pitch and available area
• Shading from trees, chimneys or neighbouring structures
• Local weather and seasonal variation
• The size of the system installed
• How and when electricity is used within the home

Solar panels do not normally eliminate an electricity bill. You will continue to pay a standing charge — currently around 57.19p per day — regardless of how much electricity you generate. Most homes also draw some electricity from the grid, particularly in the evenings and during winter months. What solar can do is reduce the number of units you purchase, which directly reduces your exposure to future unit rate changes.

Solar should be viewed as a long-term investment in your property. No accurate savings figure or payback period can be given without a property-specific design, survey and calculation, and any installer who offers headline guarantees without knowing your property is not giving you a complete picture.

Is My Roof Suitable for Solar Panels?

A common assumption is that only south-facing roofs are suitable for solar panels. In practice, the picture is more nuanced — and more encouraging for many homeowners.

South-facing roofs do tend to produce the most electricity overall, because they receive the most direct sunlight throughout the day. However, they are not the only option.

East and west-facing roofs often perform very well, and in some cases they may actually suit a household's electricity usage pattern better than a south-facing installation. An east-facing array generates more electricity in the morning; a west-facing array generates more in the afternoon and early evening. For a household with higher afternoon and evening demand, this can increase the proportion of solar generation used directly in the home.

Shading is a factor that can usually be assessed during the design stage rather than assumed to be a barrier. Modern design software — including tools that model expected generation based on roof orientation, pitch, local weather data and the position of nearby obstructions — can give a realistic picture of what a particular roof is likely to generate before any commitment is made.

Roof pitch and roof condition also matter, but these are assessed as part of the design and survey process rather than being a reason to rule out solar at the outset.

The best system design depends on when your household actually uses electricity, not simply which direction your roof faces. Omni3 uses design software to model expected generation for each property individually. Many homes can also receive an initial desktop assessment — using aerial imagery and mapping software — before any site visit is arranged, giving you a useful early indication of suitability without requiring you to commit to a visit.

What Size Solar System Is Right for My Home?

Every property is different, and the right system size depends on a combination of factors specific to your home and how you use electricity. There is no single answer that suits every household, which is why Omni3 designs systems around the customer's property rather than selling fixed packages.

When assessing the right system for a home in Worthing, Haywards Heath, Burgess Hill or anywhere else across the South East, the key considerations include:

• Annual electricity consumption — your current usage is the starting point; a recent electricity bill or your annual kWh figure is the most useful information you can share
• Available roof space — this sets the upper limit on what can physically be installed
• Roof orientation and pitch — these determine when generation peaks and how output varies across the seasons, modelled alongside the household's actual usage pattern
• Shading — from trees, chimneys, neighbouring buildings or dormer windows; modern design software can assess likely impact at the design stage
• Future EV charger installation — a household planning to charge an electric vehicle at home will have significantly higher electricity demand, which changes the case for solar and battery storage
• Future heat pump installation — heat pumps are large electrical loads and, like EV chargers, affect how a system should be sized and specified
• Battery storage requirements — whether you want to maximise self-consumption, benefit from off-peak tariffs, or both
• Household occupancy — whether someone is at home during the day affects how much solar generation can be used directly rather than exported
• Budget — a larger system is not always better value; the right balance between system size, battery capacity and cost should be assessed for each property

The aim is a system that works well for your home over the long term — not the largest system that will fit on your roof. Before requesting a full property survey, you may find it useful to explore the principles involved with the Omni3 solar savings calculator.

Why Solar Panels and Battery Storage Work Particularly Well Together

Solar panels generate electricity during daylight hours. Without battery storage, any surplus generation that is not used immediately in the home is exported to the electricity grid. This can attract a payment through the Smart Export Guarantee (SEG) scheme — a programme through which energy suppliers pay homeowners for electricity exported to the grid — though tariffs and eligibility vary between suppliers and products.

A battery changes that picture considerably. Modern battery systems can:

• Store excess solar generation that would otherwise be exported to the grid
• Increase the proportion of your own electricity you actually use — known as self-consumption
• Charge overnight using cheaper off-peak electricity tariffs, reducing reliance on expensive peak-rate grid electricity
• Discharge stored electricity during the evening and at times of higher grid prices
• Work alongside EV chargers and heat pumps, helping to coordinate when large loads draw power
• Provide backup power in the event of a grid outage, depending on the system and battery model chosen

Some homeowners are on time-of-use or off-peak electricity tariffs, under which electricity is available at a lower rate during certain hours — often overnight. A battery capable of charging during cheaper periods and discharging when grid prices are higher makes that kind of tariff structure genuinely useful, rather than something that requires significant changes to daily habits.

Battery storage is not automatically the right choice for every household. The economics depend on the tariff available, the capacity of the battery, how the household uses electricity and whether solar panels are also installed. Proper sizing matters — an undersized battery may offer limited benefit, while an oversized one may not deliver an appropriate return. Any battery recommendation from Omni3 will be based on your specific usage and circumstances, not a standard package.

Monitoring Your Solar and Battery System

One of the practical advantages of modern solar and battery installations is the visibility they give you over your household's electricity use. Most current systems include a smartphone application that allows you to monitor, in real time or near real time:

• Solar generation — how much electricity your panels are producing right now and over time
• Battery charge level — how much stored electricity is available and whether the battery is charging or discharging
• Household consumption — how much electricity your home is using in total
• Grid import — how many units you are drawing from the grid and when
• Grid export — how much surplus electricity is being sent back to the grid

This information helps in two ways. First, it lets you understand how your system is actually performing across different seasons and weather conditions. Second, it shows how small changes to your habits — running a dishwasher or washing machine during peak solar generation, for example — can meaningfully increase the proportion of your own electricity you use directly. Omni3 demonstrates the monitoring application as part of every handover.

Should I Install Solar Panels, Battery Storage or Both?

This is one of the most common questions, and the honest answer is that it depends on your property and how you use electricity.

Solar panels only may suit homes with good daytime electricity consumption — for example, where someone is at home during the day, or where flexible loads such as a dishwasher or washing machine can run during peak generation hours.

Battery storage only, without solar panels, may suit some properties on a favourable off-peak tariff, though the economics must be assessed carefully and will not work for every household.

Solar and battery together generally provides the greatest level of control and the highest proportion of self-consumed electricity, combining daytime generation with evening use of stored energy. For most households, this combination offers the most robust long-term position.

EV charger or heat pump — if you have, or are planning, an electric vehicle charger or a heat pump, this should be included at the system design stage. These are significant electrical loads that affect how a solar and battery system should be specified. Designing the installation as a whole from the outset avoids the need for costly changes later.

Solar as Part of Your Home's Long-Term Infrastructure

It is easy to assess solar panels purely against today's electricity price. A more useful frame is to treat them as part of your property's long-term infrastructure — in the same way you might think about a boiler, a roof or a new heating system.

A well-specified solar installation, once commissioned, will typically:

• Generate electricity for 25 years or more with minimal maintenance
• Continue to reduce the number of units imported from the grid whether prices are high or low
• Support future technologies — EV charging, heat pumps, home energy management — that are likely to increase your electricity demand over time
• Reduce dependence on grid electricity and the external factors that determine its price
• Improve energy resilience, so your home is less exposed to supply disruptions or sharp price movements
• Leave your household better prepared for whatever changes the energy market brings over the next two decades

Solar is not a complete solution to energy costs, and it does not suit every property equally. But for homes where it is well-matched, it offers something a standard electricity tariff does not: a degree of control over where your electricity comes from and how much of it you need to buy.

Solar and Your Home's Energy Future

The July 2026 price cap rise is part of a broader picture. Household electricity demand is likely to increase over the coming years as more homes adopt electric vehicles, heat pumps and other electrically powered technologies. Each of these increases the amount of electricity drawn from the grid — and therefore the value of generating some of that electricity at home.

• Electric vehicles are becoming mainstream. An EV charged at home adds significantly to a household's annual electricity consumption. Charging using solar generation or stored battery electricity reduces the cost per mile compared with drawing from the grid at standard rates.
• Heat pumps replace gas boilers with electrically powered heating. A home that moves to a heat pump will typically use considerably more electricity — making solar and battery storage increasingly relevant.
• Changing tariffs — time-of-use and smart tariffs are becoming more widely available, rewarding households that can shift consumption away from peak periods. A battery system designed with this in mind can make those tariff structures genuinely useful.
• Increasing household electrification — the general direction of energy policy and infrastructure investment is towards greater electrification. Homes that generate their own electricity are in a stronger position to manage costs as that transition continues.

Solar PV installation, battery storage and EV charger installation are not entirely separate decisions — they are components of a long-term energy strategy for the home. Thinking about them together from the outset generally produces better outcomes than adding each component independently over time.

Is Solar Still Worthwhile If Energy Prices Fall Again?

This is a fair question and deserves a clear answer.

The energy price cap is reviewed every three months. It has moved both up and down over recent years, and there is no certainty about where it will sit in the years ahead. Basing a long-term investment decision on a single price-cap period would give you an incomplete picture.

Solar panels, once installed, typically operate for 25 years or more. Over that period, electricity prices will rise and fall. The value of a solar installation comes from the cumulative reduction in imported units across all those years — not from any single quarter's unit rate. Even when electricity prices fall, generating and using electricity at home still means purchasing fewer units from the grid.

The case for solar does not depend on prices remaining at current levels. It rests on a straightforward principle: every unit you generate and use at home is one less unit you need to buy.

Why Summer Is a Good Time to Investigate Solar

Longer daylight hours make it easier to understand how a solar system would perform on your property. If you are at home during the day, you already have some sense of when your electricity demand is highest and how that might align with solar generation.

There is also a practical reason to begin the process now. A thorough property assessment, system design, DNO notification or application where required, and professional installation takes time. Homeowners in Pulborough, Chichester, Littlehampton, Bognor Regis and across West Sussex who start the process in summer can make a considered, unhurried decision — and if they proceed, the installation can potentially be completed before the higher consumption months of autumn and winter.

Reacting to a future price increase under time pressure rarely produces the best outcome.
