In-Roof Solar Panels

Rather than sitting above the tiles, these panels replace part of the roofing material itself, providing a flush and seamless aesthetic. Spirit Energy installs numerous in-roof solar systems, highly valued for their visual appeal, enhanced weatherproofing, and reduced maintenance needs. Homeowners choosing in-roof installations typically benefit from improved kerb appeal, which can boost property value, along with excellent energy efficiency. Ideal for new builds or roof refurbishments, in-roof panels combine practicality and style in one elegant solution.

Wall Mounted Solar Panels

Wall-mounted solar panels provide a practical solution for properties with limited or unsuitable roof space, making effective use of otherwise unused vertical surfaces. Spirit Energy has successfully completed numerous wall-mounted solar installations across the South of England, typically involving panels mounted securely on horizontal rails, fixed directly into brick or block walls with specialist screws and standard clamps.

Though they generate around 30% less energy annually compared to optimally pitched south-facing roof systems, wall-mounted panels can still outperform less ideally oriented roof arrays, making them a sensible option for many homeowners. They generally fall within permitted development rights, avoiding the need for planning permission.

Ground Mount Solar Panels

Ground-mounted solar panels offer an ideal solution when roofs are shaded, unsuitable, or simply lack adequate space. Spirit Energy regularly installs ground-mounted systems throughout southern England, securely anchoring frames directly into the ground using robust steel foundations. These installations provide flexibility in panel orientation and pitch, optimising performance and maximising annual energy output.

Although ground-mounted systems require suitable open space and may involve higher initial groundwork costs, their ease of maintenance, enhanced cooling airflow around panels, and typically higher overall efficiency can often offset these factors. As with roof-mounted panels, ground-mounted installations typically fall under permitted development rights.

Flat Roof Solar Panels

Flat roof solar installations are an excellent way to maximise unused roof space on commercial and residential buildings. Spirit Energy frequently installs flat roof systems, typically using ballast-mounted or low-penetration fixing methods, ensuring the integrity of waterproofing membranes while securely anchoring the panels. This type of mounting allows flexibility in orientation and tilt, optimising energy generation even on roofs with limited structural loading capacities.

While flat roof solar systems typically require careful consideration of shading between panel rows, their ease of installation, minimal visual impact, and straightforward maintenance make them highly attractive. In most cases, planning permission isn't required, as flat roof installations often fall comfortably within permitted development rules.

Fitting solar panels on your roof taps into free solar energy to generate clean electricity on-site, directly reducing your reliance on grid power and lowering energy bills by up to 70 per cent. High-efficiency photovoltaic cells convert sunlight into affordable solar power, cutting household electricity costs and protecting you from rising utility tariffs. Government incentives and feed-in tariffs further boost your return on investment, which is often repaid within seven to ten years, and any surplus electricity can be sold back to the grid for extra income. By choosing solar panels, homeowners secure long-term cost savings, predictable energy bills and increased property value.

Installing solar panels enhances your home’s market appeal and can increase property value thanks to improved energy efficiency and lower running costs. A high-performance photovoltaic system contributes to a higher Energy Performance Certificate rating, making your property more attractive to eco-conscious buyers and commanding a premium price. Sustainable solar power appeals to a growing market of homeowners seeking green credentials and long-term savings, while offering demonstrable return on investment. By integrating solar panels, you not only cut energy bills but also boost your home’s resale potential and investment value.

By installing a solar PV system paired with battery storage, homeowners can achieve true grid independence and energy self-sufficiency, generating and storing their own clean electricity on-site rather than drawing from the grid. This setup delivers uninterrupted backup power during outages, shields you from volatile utility prices and maximises the value of your solar investment. Advanced photovoltaic technology and lithium-ion batteries work together to capture surplus solar energy by day for use at night and in poor weather, enabling up to 100 per cent off-grid operation. Embracing solar panels for grid independence not only boosts energy security but also enhances your property’s green credentials and long-term savings.

Harnessing solar power on-site cuts household carbon emissions, replacing grid electricity generated from fossil fuels and substantially lowering your carbon footprint. High-efficiency panels convert sunlight into clean energy, reducing reliance on coal- and gas-fired power stations and shrinking greenhouse gas output. Over their typical 25-year lifespan, solar panels can save dozens of tonnes of CO₂, offering a practical way for homeowners to combat climate change and demonstrate genuine environmental responsibility.

By generating your own clean electricity on-site, solar panels provide a robust defence to mitigate rising electricity costs by reducing reliance on wholesale markets and national grid supply. Your solar array supplies a stable, self-produced power source that remains unaffected by energy price cap adjustments or seasonal tariff spikes. As utility providers shift rates in response to market volatility, adopting solar PV ensures a significant share of your household consumption is covered by predictable green energy. Coupled with smart monitoring and export agreements, you gain full control over generation, use and export of excess power, delivering lasting budget certainty and resilience against future cost escalations.

Solar panels are engineered for durability and require minimal upkeep over their 25-year lifespan. With no moving parts, routine maintenance is limited to periodic visual inspections and an occasional clean to remove dust or debris. Advanced monitoring systems track performance in real time, alerting you to any issues so you can address them promptly without costly service visits. Most installations come with comprehensive manufacturer warranties covering both panels and inverters, ensuring that any faults are repaired or components replaced at no extra cost. By choosing solar PV, you benefit from a nearly hands-free energy solution that delivers reliable performance year after year with only the simplest maintenance tasks.

Solar panels paired with battery storage systems provide reliable backup power whenever the grid fails, automatically switching to stored solar energy to keep your essential circuits or entire home running. Intelligent hybrid inverters detect outages instantly and draw from your on-site battery bank, ensuring critical appliances such as refrigerators, heating controls and lighting remain operational through the night or during extended blackouts. Scalable storage capacity lets you tailor your system to match household demand while optional generator integration offers extra redundancy for prolonged power interruptions. Remote monitoring and performance alerts give you peace of mind by flagging any issues in real time, so you can maintain uninterrupted energy security and true self-sufficiency.

My aim at Spirit is to make sure we get the right renewable energy solution for your home or business. It is a great feeling to take yourself off grid and generate your own power without needing to worry about power cuts or an increasing energy price over the next 25 years.

I have an in-roof PV installation at my home with a zappi and eddi. Having the technology you sell on your own roof fitted by the company you work for really helps to understand how the system works and what sort of experience a customer expects.
