How do solar panels work?
Solar panels (also known as photovoltaic or PV panels) convert sunlight into electricity. This electricity can be used immediately, stored in a battery, or exported back to the grid if your system is grid-connected. Even on cloudy days, solar panels can generate energy.
Will solar panels work in Northern Ireland’s climate?
Yes – solar panels work effectively even in diffused light, meaning they still generate electricity on overcast days. Northern Ireland and the UK receive enough annual sunlight to make solar a highly viable energy source.
How much can I save with solar panels?
Savings depend on your energy usage, system size, and whether you combine solar with battery storage. On average, homeowners can reduce electricity bills by up to 70% with a properly installed solar system.
Can I sell excess energy back to the grid?
Yes. If your system is connected to the grid, you can export surplus electricity through schemes like the Smart Export Guarantee (SEG), which provides payment for exported energy.
How long does a battery last?
Modern lithium-ion batteries typically last between 10 to 15 years, depending on usage and environmental factors. We only install high-quality, proven brands with strong warranties.
Can I add a battery to an existing solar system?
Absolutely. Battery storage can be retrofitted to most existing solar systems. We’ll assess your current setup and recommend the best battery solution for your needs.
Do I need a home charger if I already have a charging cable?
Yes – a home EV charger is much faster, safer, and more efficient than a standard 3-pin plug. It also allows for smart scheduling, monitoring, and energy management.
Can you install EV chargers for businesses or multi-car households?
Certainly. We provide single and multi-point EV charging solutions for homes, offices, and commercial properties. Our systems are scalable, future-proof, and compatible with all major electric vehicle models.
How long does it take to charge an electric car at home?
Most home EV chargers provide 7kW charging, which takes around 6–8 hours for a full charge – ideal for overnight charging. Faster options may be available depending on your electrical supply.
What does it mean to go off-grid?
Going off-grid means your property is completely independent from the national electricity grid. All your energy comes from local sources, such as solar panels, batteries, and optional backup generators.
Is an off-grid system reliable in rural or remote locations?
Yes. Off-grid systems are specifically designed for remote areas where grid access is limited or non-existent. We use robust technology and accurate energy profiling to ensure continuous, reliable power 24/7.
Will I need a generator as a backup?
In some cases, yes – particularly in the winter months. While solar and battery storage can meet the majority of your energy needs, we may recommend a small generator as an additional safeguard, depending on your location and energy usage.
How much does a full system cost?
Costs vary depending on the size and complexity of the installation. We provide free site assessments and customised quotes to ensure you get the best value and system performance for your needs.
Do you offer finance or payment plans?
We do not offer finance or payment plans at the moment
Are there any grants or incentives available?
There are occasionally local and national grants or incentive schemes. We stay up to date with current offerings and will advise you if you’re eligible for support when we provide your quote.
How long does installation take?
Most domestic systems are installed within 1 to 3 days. Larger or more complex systems may take longer, but we’ll always provide a clear timeline before starting any work.
What support do you provide after installation?
We offer ongoing support, maintenance, and system monitoring to ensure everything continues to run smoothly. Should you ever need help or have questions, our team is just a phone call away.
