They generate the electricity a battery stores and an EV charger consumes, and the panel install determines your inverter choice for the other two. If budget is tight, start with a hybrid-inverter solar install sized for future battery capacity — it's cheaper to add the battery later than to retrofit the wrong inverter." } }, { "@type": "Question", "name": "Do I have to buy all my services from the same installer?", "acceptedAnswer": { "@type": "Answer", "text": "No, but there are real advantages to bundling. A single installer means one warranty pack, one MCS certificate covering solar and battery, one DNO application, and no finger-pointing when something goes wrong. Bundled solar + battery + EV-charger quotes are typically 8-15% cheaper than three separate installers, and the commissioning is meaningfully cleaner." } }, { "@type": "Question", "name": "How long does each service take to install?", "acceptedAnswer": { "@type": "Answer", "text": "Solar panels: 1-2 days on the roof plus a day for inverter and commissioning. Battery retrofit: 1 day. EV charger: half a day. Commercial installs: 1-3 weeks depending on system size. Scaffolding is usually delivered 1-2 days before roof work and removed the same week." } }, { "@type": "Question", "name": "What warranties come with each service?", "acceptedAnswer": { "@type": "Answer", "text": "Solar panels: 25-30 years performance, 12-15 years product. Inverters: 10-12 years extendable to 20. Batteries: 10-15 years or 6,000+ cycles. Workmanship: 12 years via RECC / MCS. EV chargers: 3-5 years depending on brand. All warranties are backed by named manufacturers and transferable if you sell the house." } }, { "@type": "Question", "name": "Are all your services MCS-certified?", "acceptedAnswer": { "@type": "Answer", "text": "Solar PV and battery storage installs are MCS-certified — that is essential for the Smart Export Guarantee and for battery grant schemes. EV chargers do not fall under MCS but are installed to BS 7671 by qualified electricians registered with NICEIC or NAPIT. Maintenance and repairs are performed by MCS-registered engineers where the original install was MCS-certified." } }, { "@type": "Question", "name": "Can you service systems installed by another company?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. Around one in five service and repair calls we attend involves a system installed by another firm — sometimes one that has ceased trading. We re-bind monitoring, source spares, re-register the system on the MCS database where possible, and bring it back to full serviceable condition." } }, { "@type": "Question", "name": "Do you offer commercial as well as residential services?", "acceptedAnswer": { "@type": "Answer", "text": "Yes — commercial solar up to 500 kWp, agricultural buildings, community projects, workplace EV charging and battery storage integrated with demand-side response revenue. See the Commercial Solar service page for typical payback figures and grid-connection processes." } }, { "@type": "Question", "name": "How do I get a quote for multiple services at once?", "acceptedAnswer": { "@type": "Answer", "text": "Use the quote form on this page and tell us in the notes field which services you're considering — for example 'solar + 10 kWh battery + 7 kW Zappi charger'. We'll match you to an installer who does all three in-house and can price the bundle as one job." } } ] }, { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ { "@type": "Question", "name": "How often do solar panels need servicing?", "acceptedAnswer": { "@type": "Answer", "text": "Most installers recommend a check every 1-2 years.

MCS Certified Installers RECC Consumer Code 0% VAT on Solar Up to 25-Year Warranty Finance From 0% APR Rated 4.9 / 5 on Reviews Jump to a section about maintenance A well-installed solar PV system is largely fit-and-forget — but an annual or biennial health check catches small issues before they become expensive ones, keeps your warranties valid, and protects long-term yield. ## What we check Visual roof inspection, panel cleanliness, mounting integrity, DC isolator and connector condition, inverter error logs and firmware, AC switchgear, earthing, and a full performance check against expected generation. ## Why it matters Soiling alone can reduce yield by 3-7% per year, and a single failed connector or under-performing string can cost £200+ annually in lost generation. A £149 service typically pays for itself. ## Warranty preservation Most manufacturer warranties require evidence of reasonable maintenance. We keep a digital service record you can share with your installer or insurer. ## Performance benchmarking We compare your actual generation against PVGIS modelling for your postcode, roof aspect and pitch. If you're more than 8% below expected for the season, we investigate string-level performance, optimiser data (where fitted) and shading changes — trees grow, neighbours build extensions, and yield can quietly drift downward year on year. ## Inverter firmware and monitoring Most modern inverters (SolarEdge, GivEnergy, Fox ESS, Solis, Fronius) push firmware updates that improve MPPT tracking, fix monitoring bugs and add tariff features. We check you're on the current release, confirm your monitoring is reporting correctly to the cloud, and re-link the portal to your email if your previous installer disabled access. ## Battery health checks If your install includes a battery, we read state-of-health (SoH), cycle count, and charge/discharge throughput. A typical lithium battery should retain 90%+ capacity after five years; lower numbers may indicate cell imbalance or a cooling issue worth raising with the manufacturer while warranty cover applies. ## Bird and pest proofing Pigeons nesting under panels are the single most common avoidable cause of damage to South East installs. We fit mesh skirting around array perimeters during maintenance visits — it stops nesting, protects cabling, and avoids the much larger cost of stripping panels to clear an established colony.

Most installers recommend a check every 1-2 years. We can schedule recurring visits if that's easier. Do solar panels need cleaning? In most South East locations, rain cleans panels adequately. Coastal salt deposits, heavy pollen and tree sap can require a manual clean — see our cleaning service. Will a service void my existing warranty? No — independent maintenance by an MCS-registered engineer using non-invasive testing is explicitly permitted under every manufacturer warranty we've reviewed. We document everything so your warranty paper trail is stronger after a visit, not weaker. What if you find something wrong? We give you a written report with photos, a priority rating (urgent / recommended / nice-to-have) and a fixed-price quote for any repairs. There's no obligation to use us for the fix — many homeowners take the report to their original installer for warranty work. ## Get your free quote Vetted local installer · MCS certified · No obligation [Request my quote](/services/solar-panel-maintenance#quote)[Call 0333 567 1183](tel:+443335671183) South East Solar Network MCS-accredited residential solar installers across the South East of England.
