Solar & Battery Packages
Complete energy independence. One integrated system, one installer, one point of contact.
A combined solar and battery system is the most effective way to achieve genuine energy independence for your home. When designed together from the outset, the solar array and battery capacity are optimised as a single integrated system — delivering significantly better performance than two separate installations bolted together after the fact.
At Lumos Energy, our solar and battery packages are designed around your specific property and energy profile. We analyse your roof, your usage patterns, and your goals to create a system that maximises self-consumption while ensuring you generate enough surplus to justify battery storage. The result is a system that typically covers 70-80% of your annual electricity needs from your own roof.
The financial case is compelling. With 0% VAT on the entire installation (panels, battery, inverter, and labour), combined with the Smart Export Guarantee for any surplus you do export, payback periods in the South West typically fall between 5 and 8 years. After that, you are generating free electricity for 20+ years.
As a single installer handling the complete system, there is no coordination headache, no compatibility issues between components, and one point of contact for everything from design through installation to long-term support.

Why Choose a Combined System?
Integrated Design
Solar panels and battery sized together for optimal performance — not two separate systems bolted together.
Maximum Savings
Combined systems typically save 70-80% on electricity bills, with payback periods of 5-8 years in the South West.
Single Installer
One company designs, installs, and supports your entire system. No finger-pointing between separate solar and battery installers.
0% VAT on Everything

Solar & Battery FAQs
A typical 4kW residential solar panel system in Wiltshire costs between £5,000 and £7,000 including installation, with 0% VAT until March 2027. Larger systems (5-6kW) range from £7,000 to £9,000. Every Lumos Energy quote is bespoke — based on your roof, your usage, and your goals.
A typical 4kW system in the South West generates approximately 3,920 kWh per year. At current electricity rates, this can save £800-£1,200 annually depending on your self-consumption rate. Adding battery storage increases savings further by using more of your own generation.
Most residential solar systems in Wiltshire and the South West pay for themselves within 5-8 years, depending on system size, energy usage, and whether you add battery storage. After payback, you generate free electricity for 20+ years.
Yes. Since April 2022, domestic solar panel installations in the UK have been zero-rated for VAT. This applies to panels, inverters, battery storage (when installed with solar), and installation labour. The 0% rate is currently guaranteed until March 2027.
The SEG pays you for surplus electricity you export to the grid. Current rates are approximately 10.8p per kWh. Your system must be MCS certified to qualify — all Lumos Energy installations are MCS registered as standard.
