FAQ’s

Your savings depend on your current electricity usage, roof orientation and system size. Most Essex homeowners see significant reductions in their electricity bills, with many systems paying for themselves within 6-10 years through energy savings. Our team provides detailed projections based on your specific circumstances and energy usage patterns.

We offer three main options to suit different budgets and requirements:

  • Ja Solar: Budget-friendly panels offering excellent value for money
  • Longi: Mid-range panels providing reliable performance and durability
  • Aiko Neostar: Premium panels delivering maximum efficiency and energy generation

Our engineers assess your roof space, energy needs and budget to recommend the optimal choice for your property.

Yes, solar panels work effectively in Essex conditions. They generate electricity from daylight, not just direct sunlight, so they produce energy even on cloudy days. Essex receives good solar irradiation throughout the year, making it an ideal location for solar installations.

Most residential solar installations fall under permitted development rights and don’t require planning permission. However, some restrictions apply to listed buildings, conservation areas, or certain roof configurations. We assess your property and advise on any planning requirements during our site survey.

Battery storage transforms your solar investment by storing excess energy generated during the day for use during evening peak hours when electricity is most expensive. This maximises your energy independence and savings, particularly beneficial during winter months when daylight hours are shorter.

We provide three tiers of battery storage:

  • Fox ESS: Cost-effective systems offering reliable energy storage
  • Duracell: Mid-range batteries with proven reliability and strong warranties
  • Sigenergy: Premium systems with advanced features (10kW system available for £3,920)

All our battery systems are stackable, allowing you to start small and expand capacity as needed.

Modern lithium batteries typically last 10-15 years with minimal capacity loss. Most manufacturers provide warranties of 10 years or more and batteries often continue performing well beyond their warranty period.

In most cases, yes. We can retrofit battery storage to existing solar installations, though the complexity depends on your current system configuration. Our engineers assess your existing setup and recommend the best integration approach.

We install chargers from leading manufacturers including Tesla, Hypervolt, Sigenergy and Duracell. Each brand offers different features and capabilities and we help you choose the right charger based on your vehicle, usage patterns and integration requirements.

Yes, smart EV chargers can be integrated with solar systems to charge your vehicle using renewable energy. This provides the ultimate in sustainable transport, allowing you to power your car with clean energy generated on your own roof.

Home chargers typically operate at 7kW or higher, charging most electric vehicles overnight. This is much faster than standard domestic plugs and more convenient than public charging stations.

Most EV charger installations require dedicated electrical circuits and may need consumer unit upgrades. Our qualified electricians assess your existing electrical system and carry out any necessary upgrades as part of the installation process.

Beyond renewable energy installations, we provide comprehensive electrical services including:

  • Domestic and commercial electrical installations
  • EICR testing and certification
  • Consumer unit upgrades
  • Fire alarm systems and CCTV
  • Fuseboard upgrades and rewiring
  • Full electrical compliance services

Yes, all our electrical work includes full certification and compliance documentation. We provide electrical installation certificates, EICR reports and all necessary paperwork for insurance and regulatory requirements.

Absolutely. We provide electrical services for industrial units, retail spaces, farms and office buildings. Our commercial services include lighting upgrades, full rewires, refurbishments and office fit-outs throughout Essex.

We provide services throughout Upminster, Hornchurch, Brentwood, Billericay and Loughton. Our local presence ensures quick response times and ongoing support for all installations.

Most residential solar installations take 1-2 days, while battery storage additions typically require half a day. EV charger installations usually complete within a few hours. We provide specific timelines during your consultation based on your particular requirements.

We stand behind all our work with comprehensive warranties and ongoing support. As a local company, we’re always available to address any concerns quickly and professionally. Our installations include full manufacturer warranties plus our own workmanship guarantees.

While solar and battery systems require minimal maintenance, we provide ongoing support including performance monitoring guidance, system health checks and any necessary repairs or adjustments.

Yes, we provide flexible finance options to help spread the cost of installations. Our transparent financing makes renewable energy accessible while allowing you to start benefiting from energy savings immediately.

All equipment comes with manufacturer warranties (typically 10-25 years for solar panels, 10+ years for batteries). We also provide installation warranties covering our workmanship and ensuring long-term system performance.

Yes, renewable energy installations consistently add value to properties. Many homeowners find the added property value exceeds the installation cost, making it not just an energy investment but a property investment as well.
