While we do not install meters ourselves, you will need a second-generation smart meter (SMETS2) to track the electricity you export to the grid. This is essential if you wish to receive payments through the Smart Export Guarantee (SEG).

In most cases, solar panels fall under "Permitted Development." However, planning permission may be required if your property is a listed building, situated in a Conservation Area or AONB, or if you are installing a large ground-mounted array. Our team provides expert guidance on these applications, and we can always work to secure planning permission prior to an installation agreement being signed.

Commercial projects vary significantly; a 50kW warehouse system might take a week, while multi-megawatt arrays can take several weeks to complete. Residential installations usually take 1 to 2 days, depending on the system size and whether a battery is included.

We deliver a seamless, ISO9001‑accredited installation experience, keeping you informed at every stage and ensuring your system is designed, installed and handed over to the highest standards. With a dedicated point of contact, fully trained installers, strict on‑site safety, and a thorough walk‑through at commissioning, we’re with you every step of the way.

The physical installation of panels and electrical components usually takes just one day with minimal disruption. The entire process, from initial quote and technical survey to final commissioning, typically takes between two and four weeks.

The average 3-bedroom UK home typically requires between 8 and 12 solar panels to meet its energy needs. The exact number depends on your annual kWh consumption and the wattage of the specific panels you choose.

Standard solar systems automatically shut down during a power cut for safety reasons to prevent electricity from feeding back into the grid. However, if you have a battery storage system with "backup" capabilities, you can continue to power essential items during an outage.

Yes, you should inform your insurance provider to ensure the panels are included in your buildings' cover. Failing to do so could void your policy or leave the expensive equipment unprotected against theft or accidental damage.

Yes, energy-efficient homes are increasingly in demand, often selling faster than properties with high running costs. Buyers are often attracted to the "move-in ready" benefit of having lower electricity bills from day one.

Standard home warranties usually do not cover solar panels; instead, they are protected by specific manufacturer warranties (product and performance) and your installer's workmanship warranty. At Geo Green Power, we provide a lifetime installation warranty when you take out a service plan, alongside long-term panel guarantees.

While you can legally install panels yourself, you must use an MCS-certified installer to qualify for the Smart Export Guarantee (SEG) and most insurance policies. Professional installation also ensures that the system meets strict UK building and electrical safety regulations.

The core components include solar PV panels, a mounting system, an inverter, and generation meters to track output. You may also choose to add a battery storage system and an EV charger for greater energy flexibility.

Panels connect to an inverter, which converts the solar-generated DC power into AC power for use in your home electrical system. The inverter is then wired directly into your consumer unit (fuse box) to distribute power to your appliances.

Solar panels are largely self-cleaning due to the UK's rainfall, but they can be cleaned using water and a soft brush if dirt builds up. For safety and to avoid damaging the glass, it is recommended to hire a professional cleaner or use extendable tools from the ground.

Selection is based on your specific energy goals, available roof space, and budget, often favouring Tier 1 manufacturers for better efficiency and warranties. A professional survey will help determine the best panel type, such as monocrystalline for high efficiency, for your property.

A modest 4kW system can generate approximately 3,400kWh to 4,000kWh of electricity per year, which is enough to cover the average UK household's annual usage. The actual generation depends on your location, roof orientation, and the amount of daylight received.

Most modern solar panels are designed to last 25 to 30 years or more, often coming with a 25-year performance warranty. While panels are long-lasting, the system inverter typically needs replacing after about 12 to 15 years.

Solar energy can power all standard household appliances, lighting, and heating systems, and can even be used to heat water via a solar diverter. Any excess energy can be stored in a battery for later use or sold back to the grid through the Smart Export Guarantee (SEG).

In most cases, solar panels are covered under standard building insurance because they are considered permanent fixtures of the property. You should notify your insurer after installation to ensure your rebuild cost is accurately updated.

Yes, you can use solar energy to charge an electric vehicle by integrating an EV charging point with your solar PV system. Adding a battery allows you to store solar energy generated during the day to charge your car overnight.

While possible in theory, most UK homes remain connected to the grid to ensure a consistent power supply during the night or winter months. To achieve total independence, you would typically need a very large array combined with significant battery storage and a reduction in energy usage.

A premium residential solar PV system, using the highest quality materials, and designed to last for 25 years can cost between £10,000 and £15,000, though this varies based on system size and property type. These costs typically include the panels, inverter, and full professional installation.

Yes, studies show solar panels can increase a home's value by 2% to 14%, depending on location and system size. They also improve your Energy Performance Certificate (EPC) rating, making the property more attractive to future buyers.

Under current UK regulations, most wall-mounted EV chargers fall under "Permitted Development" and do not require formal planning permission. However, you may still need to seek approval if your property is a listed building, in a conservation area, or if the installation exceeds specific size and height limits.

You primarily need dedicated off-street parking (like a driveway or garage) and a modern consumer unit with sufficient electrical capacity. Our specialists will conduct a survey to check your property’s wiring and Wi-Fi signal strength before beginning the installation.

As of 2025, the OZEV EV Chargepoint Grant provides up to £350 for renters, flat owners, and homeowners with no off-street parking who are installing cross-pavement solutions. Landlords and businesses can also access significant funding to support the installation of charging infrastructure across their properties.

A typical home charger draws around 7kW of power, which is like the demand for an electric shower or a large heat pump. Smart chargers use "load management" to monitor your home's total power usage, automatically slowing the car charge if other heavy appliances are running simultaneously.

Standard 7kW home chargers typically provide about 25–30 miles of range per hour of charging, which is roughly three times faster than a standard three-pin plug. A full overnight charge is usually more than enough to top up even the largest EV batteries from empty to full.

Most modern "smart" chargers require a Wi-Fi or 4G data connection to access features like remote scheduling and firmware updates. This connectivity is also essential for syncing with smart energy tariffs, allowing the charger to automatically start when electricity prices are at their lowest.

Installing a dedicated EV charging point is a smart investment that can increase property value by making your home more attractive to the growing market of electric vehicle drivers. Many buyers now view a pre-installed charger as a premium "move-in ready" feature that enhances a home's sustainability credentials.

While a home charger offers the most convenience and lowest costs, you can own an EV by relying on workplace, destination, or public rapid-charging networks. However, without home charging, you may miss out on significant savings from overnight off-peak energy tariffs.

Yes, EV chargers must be installed by qualified electricians to ensure compliance with BS7671 wiring regulations and safety standards. Using an MCS and OZEV-certified installer like Geo Green Power also ensures your warranty remains valid and qualifies you for potential grants.

Most smart chargers allow you to lock the unit via an app or use RFID cards to prevent unauthorised access. Conversely, you can also choose to share your charger with others through community-charging apps if you wish to earn extra income.

Fixed EV chargers are generally treated as permanent fixtures and are typically covered under the buildings section of your home insurance policy. We recommend notifying your provider after installation to ensure your total rebuild cost accurately reflects the new equipment.

Yes, you can install two chargers, provided your home electrical incoming supply can handle the combined load. We often use "load-balancing" technology to share the available power between both units, ensuring your household fuse is never overloaded.

Yes, most home chargers are specifically designed with high IP ratings to withstand the UK's weather conditions and can be safely installed on exterior walls or pedestals. Our team will ensure the unit is positioned conveniently for your driveway while maintaining full protection from the elements.

We select a charger based on your vehicle's connector type and your home's electrical supply, typically choosing a 7kW smart charger for the best balance of speed and efficiency. Considering "solar-ready" models if you already have panels, and ensure the unit is compatible with smart energy tariffs to maximise your savings.

Geo Green Power provides thorough aftercare following the installation of an EV charging station. Don’t hesitate to contact our specialist!

Geo Green Power provides the following EV charging systems: MyEnergi Zappi 7kW, Tesla Wall Connector 7kW, GivEnergy 7.2kW and Rolec pedestals.

EV chargers are cost-effective, highly convenient, and time-saving. The value of a house is also likely to increase with the addition of an EV charger.

Although leaves and moss rarely cause issues, as panels sit close to the roof, any debris accumulation under the panels can be dealt with by our team during a maintenance visit. If you spot moss development, inform your solar panel cleaner so they can ensure its complete and careful removal.

Birds, especially pigeons, are drawn to the sheltered, shaded, and protected space beneath solar panels for nesting. To proactively prevent this common issue, Geo Green Power can pigeon-proof your solar PV system during installation. Simply ask about this service when you book your consultation, and we will include it in your order.

Solar panels will be most efficient when the sun is hitting them directly, which is around midday. Light intensity is the most important factor when considering efficiency – when the sun is lower in the sky, light won’t be as intense, and this will reduce the output of your panels. Seasonal changes can also affect the efficiency of your panels, as during the summer, the sun shines for longer than in winter. From around May to September, your residential solar PV system will produce more energy than from October to April as the days are shorter. However, remember that solar panels don’t need direct sunlight to function. Even on cloudy days, your solar panels will still absorb light and continue to work effectively. Whatever the weather, you can benefit from energy production year-round; it will simply be more effective on sunnier days and at times when the sun is highest in the sky.

In most cases, local rainfall and the angle of installation mean that solar panels are self-cleaning. However, dust, bird droppings, tree sap, lichen and other dirt can build up, so occasionally it is worth cleaning them manually. A spray with a garden hose is often enough to remove surface dirt, or most window cleaning companies will have a reach-and-wash system that can be used to get the panels thoroughly clean quickly. We do recommend an annual service of your solar PV system, and as part of this, our team can inspect your panels and assess whether they need cleaning.

Solar panel replacement cost will depend on how easy it is for us to reach and replace a specific panel. Costs would vary from £350 + VAT for the panel and work involved.

Yes. Solar panel systems are designed so that you can easily handle solar panel replacements if required.

It’s unlikely that your panels will stop working, as there are no moving parts; a fault with your system is much more likely to be an error with your inverter. Panels do, however, stop working if they are damaged by falling objects, if they or the cabling is moved and become loose or if they become excessively dirty. All these issues can be identified during service.

Depending on how good the manufacturer is, inverters typically have a life span between 10-15 years. Fault codes on inverters vary depending on the manufacturer. Some common codes to look out for include:

• Error 509 = No energy is being fed back to the grid. The common cause of this error is dirt or debris on your panels.
• Error 314 = This is a calibration timeout, which should rectify itself when the inverter repeats its start-up routine.
• Green Flashing Light = A connection issue. Once the conditions for the feed-in operation are met, the inverter will start the feed-in operation. Make sure the power supply is secure and connected to the solar PV system.

If you’re detecting any of these issues, call our maintenance team today!

Most solar panels come with a minimum 20-year warranty, so they’re truly future-proof! If there’s an issue, it’s more likely to be your inverter or power supply. The lifespan of inverters, unfortunately, isn’t as long as that of the panels. Before you report a fault, it’s worth checking a few things: Is there enough ventilation? Inverters can overheat if not provided with space to breathe. Making sure they’re not boxed in or near heat sources (radiators, etc.) is important to ensure the longevity of your inverter. Is the inverter clean and free of dust? Regularly cleaning your inverter can extend its lifespan, as dust can easily clog up the vents and cause overheating.

One easy way you can check if your panels are performing at their best is to check the estimated annual generation figure, which you can find in your MCS certificate. If this number isn’t accurate to the figure on your generation meter, then this can be a sign that there may be an issue with your system. Checking your generation figure every quarter is a great habit to get into, especially when you’re approaching the warmer months, as you’ll want your panels working at full capacity and taking advantage of the summer sun!

Most units are roughly the size of a small radiator or a medium-sized suitcase, though dimensions vary by brand. High-capacity systems or modular units may require more wall or floor space in your garage or utility room.

An average UK home typically requires a battery between 5kWh and 10kWh to cover evening demand. To find your exact size, match the capacity for your daily evening energy consumption and the output of your solar array.

Most modern lithium-ion solar batteries last between 10 and 15 years, depending on usage and cycle frequency. They typically come with a warranty that guarantees a certain level of capacity after a decade of use.

The premise that they require a "high amount" of servicing is a misconception; they are generally much lower in maintenance than combustion boilers. However, because they rely on moving a high volume of air or fluid through fine heat exchangers to extract energy, keeping the system clean and the pressures balanced is vital to preventing the system from working too hard and increasing your electricity bills.

Yes. Most common issues, such as faulty sensors, blocked filters, or minor electrical faults, can be repaired quickly by a specialist. Even major components like compressors or fans can be replaced, though regular maintenance is the best way to avoid the need for these more significant repairs.

A well-maintained air source or ground source heat pump typically has a lifespan of 20 to 25 years. This is significantly longer than a traditional gas boiler, which usually needs replacing every 10 to 15 years, making the heat pump a far more durable long-term investment.

A standard professional service typically takes between 1.5 and 2 hours to complete. During this time, the engineer will perform all necessary safety and efficiency checks, clean the components, and provide you with a detailed report on the health of your system.

Heat pumps must be serviced by qualified, MCS-accredited renewable energy engineers. Because these systems use specialised refrigerants and F-Gas technology, they cannot be maintained by standard gas engineers; only technicians with specific heat pump training have the tools and knowledge to correctly calibrate and repair these units. At Geo Green Power, we’re fortunate to have Rob Jennison (Heating Installation Manager) and Yasmin Gibson (O&M Manager) with their endless heat pump expertise.

At Geo Green Power, a standard domestic heat pump service starts from £275 + VAT. This price ensures your system is handled by accredited engineers and includes a full performance report; however, the cost may vary slightly based on your location and the specific complexity or size of your installation.Polite notice: If our engineer cannot gain entry on a confirmed appointment, please be aware that you may incur an abortive fee.

Industry standards and manufacturer guidelines recommend that your heat pump is professionally serviced once every 12 months. Homeowners in coastal areas or high-pollution urban zones may benefit from more frequent checks to clear salt or debris build-up from the external heat exchanger.

Yes, while heat pumps are incredibly reliable with fewer moving parts than a boiler, they still require regular professional attention. Servicing is essential to maintain your manufacturer’s warranty, ensure the system is running at its highest possible efficiency (SCOP), and prevent minor issues from escalating into expensive mechanical failures.

A comprehensive service includes a full visual inspection of the indoor and outdoor units to check for wear, leaks, or damage. Our engineers will clean the evaporator coils and filters to ensure maximum airflow, test the electrical connections, check refrigerant levels and pressures, and verify that the control settings and thermostats are operating at peak efficiency.

Yes. If you are installing a system larger than 3.68kW (single phase) or 11.04kW (three phase), you must get prior permission from the Distribution Network Operator (DNO). This is known as a G99 application. Our planning and permissions team handles all the technical paperwork and grid applications for you, ensuring your system is fully legal and ready to export power to the grid as soon as it is commissioned.

Yes, in a recent update to the Boiler Upgrade Scheme (BUS), the government introduced a £2,500 grant specifically for air-to-air heat pumps. While this is lower than the £7,500 for wet systems, air-to-air units are often cheaper to install and provide the added benefit of high-efficiency air conditioning during the summer months.

Are SEG payments taxable for homeowners? For the vast majority of UK homeowners, income earned from the Smart Export Guarantee (SEG) is tax-free. HMRC generally considers this income exempt as long as the system is installed primarily for personal use and the amount generated does not significantly exceed (usually by more than 20%) the amount of electricity the household consumes.
