Our focus on clear communication and dependable service ensures that moving to solar feels straightforward, efficient and genuinely worthwhile.
Every solar system needs to be designed to suit the roof it’s installed on, taking into account its size, shape and layout. We also look at how much energy your home uses, the direction your roof faces and any shading from nearby trees or buildings. At 100% Solar Energy, we use reliable, high-quality panels that perform well even in lower light. Above all, we focus on clear guidance and a friendly, supportive service throughout your solar journey.
We start by looking at whether your home or business is well suited for solar. This involves checking the roof’s orientation and angle, noting any areas of shade and making sure the structure can safely support the panels. If your property is a good fit, we create a bespoke design based on your needs. We determine the right number of panels and map out the most effective layout to maximise energy generation.
When installation day takes place, our team begins by preparing your roof and positioning each panel with precision to ensure a secure and durable fit. We then install the inverter, the component responsible for converting the energy captured by the panels into usable power for your home. A certified electrician integrates the system with your property’s electrical network, ensuring everything operates seamlessly. To conclude, we conduct a full series of technical checks to verify that the entire system meets safety standards and is performing at its highest efficiency.
Every installation includes a personalised mobile app that lets you stay connected to the solar system at all times. You can check your energy production in real time, monitor your home or business consumption and see your savings instantly. The app also shows daily, weekly and monthly performance, and sends alerts if anything unusual occurs. Simple and secure, it puts your whole system in the palm of your hand, giving you a modern and complete way to make the most of the sun’s energy.
With 100% Solar Energy, you’re not just installing solar panels. You’re investing in a complete, modern solution designed to help you make the very most of the sun’s power.
How long does a solar panel instalation take ?
The time required can vary, but most systems are fully installed within 1 to 2 days. The complexity of the setup, the type of roof and weather conditions all play a part in determining how quickly the work can be completed.
Can solar panels operate when it's cloudy or after dark ?
Solar panels continue to produce power on overcast days, although the output is lower than in bright conditions. Once it gets dark, they stop generating altogether. If your system includes a battery, the energy stored during daylight hours can then be used to keep your home running through the evening and night.
Do Solar panels work in winter?
Yes, solar panels continue to operate throughout winter. Shorter days mean reduced daylight, but panels still generate electricity even in cold or overcast conditions. In fact, they often perform efficiently in cooler temperatures, making them reliable all year round.
How much will I save with a solar panel installation?
Savings depend on factors like your system size, how much electricity you use during the day, your tariff and whether you have a battery. Many households can cut their electricity bills by 30–60%, and you may also earn money by exporting surplus energy back to the grid, further increasing your overall savings.
