Savings vary depending on your roof size, energy use, and whether you add battery storage. Most homeowners in Crawley see their electricity bills fall by 25–50% once their solar system is installed. During your consultation, we’ll provide a tailored estimate for your property.
Almost certainly. We use satellite imagery to assess your roof’s direction, shading, and pitch before creating your design. An independent surveyor then confirms the details in person to ensure everything is suitable before installation.
In most cases, no. Solar panels are classed as “permitted development” for residential properties. If your home is listed or within a conservation area, we’ll guide you through any additional requirements to make the process easy.
Most of our solar installations are completed in just one day. Once grid approval and scaffolding are arranged, our in-house electricians and roofers handle everything, keeping disruption to a minimum.
Solar panels are low-maintenance and designed to last for decades. We recommend a simple annual clean and inspection to keep them performing efficiently. Our team can advise you on upkeep or arrange this for you.
Yes. Many of our customers start with solar panels and add a battery system later to store surplus energy. We design all our installations with flexibility in mind, so upgrading in the future is straightforward.
