Frequently Asked Questions

Solar panels contain photovoltaic (PV) cells that convert sunlight into direct current (DC) electricity. An inverter then converts this DC power into alternating current (AC) electricity that powers your home. Any excess energy can be stored in batteries or sent back to the grid through net metering.

Yes! While solar panels are most efficient in direct sunlight, they still generate electricity on cloudy days. Modern panels can produce 10-25% of their normal output even on overcast days. The UK gets enough sunlight year-round to make solar a worthwhile investment.

Quality solar panels typically last 25-30 years or more. Most manufacturers offer 25-year performance warranties, guaranteeing at least 80-85% of original efficiency after 25 years. Inverters usually last 10-15 years and may need replacement during the system's lifetime.

Solar panels require minimal maintenance. We recommend annual inspections and cleaning 1-2 times per year to remove dirt, leaves, and debris. Most systems include monitoring that alerts you to any performance issues.

Most residential installations are completed in 1-3 days. The entire process from consultation to activation typically takes 3-6 weeks, with most of that time spent on permitting and utility approvals rather than physical installation.

No. Professional installers mount panels using specialized equipment that protects your roof. We inspect your roof before installation and may recommend repairs if needed. Properly installed solar panels can actually protect the roof area they cover.

We strongly recommend professional installation. Solar systems involve electrical work, roof penetrations, and local permitting requirements. Professional installation ensures safety, optimal performance, and warranty coverage.

Standard grid-tied systems shut down during outages for safety reasons. However, systems with battery storage can provide backup power. We offer battery solutions that keep essential appliances running during grid outages.

Residential systems typically range from £5,000-£12,000 depending on size and components. The average home needs a 3-6kW system. We offer free consultations to provide accurate quotes based on your specific needs and energy usage.

We offer several financing options including cash purchase, solar loans, and Power Purchase Agreements (PPAs). Many customers qualify for 0% interest financing. We help you find the best option for your budget and goals.

Yes! The UK offers the Smart Export Guarantee (SEG), which pays you for excess energy sent to the grid. You may also qualify for VAT reductions and local authority grants. We help navigate all available incentives.

Most homeowners see payback in 6-10 years through energy savings and incentives. After that, you enjoy free electricity for the remaining 15-20+ years of the system's life. Total 25-year savings often exceed £20,000.

Most homeowners save 50-70% on electricity bills. Savings depend on system size, energy consumption, and electricity rates. Our calculator can provide personalized estimates based on your specific situation.

Excess energy can be stored in batteries or sent back to the grid through net metering. The Smart Export Guarantee pays you for exported electricity, typically 3-7p per kWh, turning your solar system into an income source.

Yes! Studies show homes with solar sell for 3-4% more on average. Solar panels are viewed as valuable upgrades that reduce operating costs and appeal to environmentally conscious buyers.

All our systems include smart monitoring apps that track real-time energy production, consumption, and savings. You can view performance from your smartphone and receive alerts about any issues.

System size depends on your energy consumption, roof space, and budget. The average UK home needs 3-6kW (10-15 panels). We conduct a detailed energy assessment to recommend the optimal size for your needs.

South-facing roofs are ideal but not required. East and west-facing roofs work well too, producing 85-90% of a south-facing system. We design systems to maximize production regardless of roof orientation.

Yes! Most systems are designed to be expandable. We can add panels as your energy needs grow or budget allows. It's easier to expand if planned from the start, so mention this during consultation.

Some shading is often manageable with proper system design and panel placement. Modern microinverters and optimizers minimize shading impact. We conduct shade analysis during site assessment.

Batteries provide backup power, maximize self-consumption, and increase energy independence. They make sense if you want backup power during outages or experience time-of-use electricity rates. We help you evaluate if batteries suit your needs.

Modern lithium batteries last 10-15 years and include 10-year warranties. They're designed to handle thousands of charge cycles. When they eventually degrade, batteries can usually be replaced without changing the solar panels.

Most homes benefit from 10-15kWh of storage. This covers evening energy use and provides backup for essential loads. We analyze your consumption patterns to recommend appropriate battery capacity.

Yes! Most solar systems can be retrofitted with batteries. Some inverters are battery-ready, while others may need upgrades. We assess your current system and recommend the best battery integration approach.
