All your Domestic Solar Questions Answered

Got questions about domestic solar panels? TRE Energy is here to help. Our experts provide clear, concise answers, guiding you every step of the way.

TRE Energy installs high-efficiency photovoltaic (PV) solar panels from top-tier manufacturers, such as SunPower and LG. These panels are known for their durability, high performance, and long-term reliability.

We carefully select panels best suited to your home's unique energy needs, ensuring maximum energy output and savings. Each installation is customised to provide optimal efficiency.

The cost of installing solar panels with TRE Energy varies based on several factors, including the size of the system, the complexity of the installation, and your geographic location. TRE Energy helps you take advantage of available local incentives and rebates, which can significantly reduce the overall cost. Additionally, we offer flexible financing options to make the transition to solar energy more accessible.

In most cases, installing solar panels does not require planning permission, especially for residential properties. However, exceptions may apply if your dwelling is a listed building, located in a conservation area, or subject to specific local regulations.

TRE Energy's team is experienced in navigating these regulations and will help you determine whether planning permission is needed. We handle all necessary paperwork and ensure compliance with local building codes and regulations, providing a hassle-free installation process.

TRE Energy's solar panels typically have a lifespan of 25-30 years. These panels come with warranties that guarantee at least 80% of their original efficiency after 25 years, ensuring reliable energy production over the long term. With proper maintenance and care, many solar panels can continue producing electricity beyond their warranty period.

TRE Energy also offers ongoing maintenance services to help extend the lifespan and efficiency of your solar energy system, protecting your investment.

Yes, the angle and orientation of your roof can significantly impact the efficiency of your solar panel system. Ideally, solar panels should be installed at an angle that maximises their exposure to sunlight throughout the day.

TRE Energy conducts thorough site assessments to determine your panels' optimal installation angle and placement. We use advanced modelling tools to simulate different scenarios and design a system that maximises energy production based on your roof's specific characteristics.

Yes, shading can reduce the efficiency of solar panels by blocking sunlight. Even partial shading from trees, buildings, or other obstructions can impact energy production.

TRE Energy uses advanced shading analysis tools to assess potential issues and design systems that minimise shading effects. We ensure consistent and reliable energy output by strategically placing panels and using technologies like microinverters or power optimisers, even in less-than-ideal conditions.

Despite the variable climate, Northern Ireland, Ireland, and the UK are suitable for solar energy generation. Modern solar panels are highly efficient and can generate electricity even on cloudy days.

TRE Energy's systems optimise energy production under local weather conditions, providing reliable and sustainable power year-round. Additionally, the longer daylight hours during summer can offset the shorter days in winter, ensuring consistent energy production.

Yes, all TRE Energy operatives are fully certified and trained to the highest industry standards. This includes certifications from recognised bodies such as the Microgeneration Certification Scheme (MCS) and the Renewable Energy Consumer Code (RECC).

Our team's expertise and professionalism guarantee a seamless installation process, adherence to safety protocols, and optimal system performance. We take pride in our commitment to quality and customer satisfaction, ensuring you receive the best service possible.

Solar panels provide clean, renewable energy to power various household needs, including lighting, heating, cooling, and appliances. By generating your own electricity, you can reduce reliance on the grid, lower energy bills, and contribute to a more sustainable environment.

Solar panels can also be used with battery storage systems to provide backup power during outages, further enhancing energy independence and reliability.

TRE Energy offers extensive warranties on its solar panels, typically lasting 25 years. These warranties cover performance guarantees, ensuring that your panels produce a specified amount of energy over their lifespan. Additional warranties may cover installation and other system components, providing comprehensive protection and peace of mind.

Yes, TRE Energy provides a range of financing options to make solar panel installations more affordable for homeowners. These options include solar loans, leases, and power purchase agreements (PPAs), allowing you to spread the cost over time and start saving on energy bills immediately.

Our team can help you explore the best financing options based on your financial situation and energy goals, ensuring a smooth and cost-effective transition to solar energy.
