- Why Choose Solar Panels?
Solar energy is at the core of what we do at Polar Energy Ltd. As specialist solar PV installers in Devon and the South West, we design and install high-performance solar panel systems that deliver real savings, long-term reliability and environmental benefits.
Our foundation is 30+ years of electrical work. We don’t just install solar panels – we engineer complete energy systems designed to give you the highest return on investment with reliable operation for decades.
Our every solar installation process begins with a detailed design analysis. We assess your property’s roof layout, orientation, shading, energy consumption and grid connection requirements to create a bespoke solar PV system that is optimised for maximum energy generation and is also compliant with MCS standards.
Whether you’re a homeowner looking to cut electricity costs or a business seeking sustainable energy solutions, our NAPIT-registered team manages every aspect of your solar project, from initial design and DNO applications (G98/G99) through to installation, commissioning and certification.

Generate your own clean electricity and significantly reduce what you pay to energy suppliers. With rising energy costs, solar panels offer long-term savings and protection against future price increases. Most Devon homeowners achieve payback in 6-8 years and also get decades of free electricity thereafter.
Solar PV systems produce zero-emission renewable energy which ultimately helps you reduce your environmental impact and contribute to a cleaner, greener future. For instance, if you install a typical 4kW system, you can save approximately 1.5 tonnes of CO2 annually by using this green energy.
Homes and businesses with solar installations are increasingly attractive to buyers and tenants, offering lower running costs and sustainable credentials. Your property’s value can increase by up to 4-5% with solar.
Reduce reliance on the National Grid. When combined with battery storage, solar panels allow you to store excess energy and use it when you need it most. This will help you achieve up to 60% energy independence.
Benefit from schemes such as the Smart Export Guarantee (SEG), which pays you for surplus energy exported back to the grid. Current rates range from 3-15p per kWh exported.
Solar panels require minimal maintenance and are designed to last 25+ years so they can deliver decades of clean, cost-effective energy with virtually no moving parts to fail.
Polar Energy Ltd specialises in residential solar installations across Devon and Cornwall. Whether you live in a detached house, semi-detached, terraced bungalow or new build, we design solar systems to suit your property and energy needs.
What’s included in our domestic solar packages:
Reduce operating costs and demonstrate environmental responsibility with commercial solar PV systems from Polar Energy Ltd. We work with businesses across Devon and Cornwall to deliver tailored solar solutions that maximise return on investment and meet ESG goals.
Ideal for
Combine your solar PV system with battery storage to store excess energy generated during the day and use it during evenings, overnight, or during peak tariff periods. Battery storage increases self-consumption from 30-40% to 70-80%, reduces grid reliance and maximises the financial return of your solar installation.
We install premium solar panels and inverters from leading manufacturers to ensure reliability, efficiency and long-term performance.
All equipment comes with manufacturer warranties and is installed to MCS and NAPIT standards.
Polar Energy Ltd designs and installs solar PV systems in compliance with MCS (Microgeneration Certification Scheme) standards. MCS certification is essential for:
All our renewable installations include RECC-backed insured warranties and deposit protection for complete peace of mind.
Solar panel costs can vary and depend on system size, equipment and installation complexity. In addition to that, MCS certification, all DNO application fees, scaffolding and RECC-backed warranties are also added to the total cost. Contact us and we will provide a free, no-obligation estimate to suit your individual needs and requirements.
Savings depend on your energy usage, system size and electricity tariff. Energy savings vary along with payback periods. During the design process, we will calculate your estimated savings and payback period in your individually customised proposal.
Generally, a typical 3-4 bedroom family home in Devon would choose a system around 4kW to 6kW, which translates to 10-14 panels. However, the exact number varies according to your available roof space, energy usage and whether you want full or partial energy independence. Our detailed assessment will provide you with precise recommendations.
All projects vary depending on system size and complexity. We’ll provide a complete timeline of the installation process in our assessment.
Yes, battery storage can be retrofitted to existing solar systems just so long as the inverter is a hybrid type inverter. We design systems with future expansion in mind.
