Solar PV & Battery Storage Systems Designed to Perform
Considered solar design and accredited installation that improves EPC ratings, reduces energy costs and delivers long-term value.
Solar PV & Battery Storage
Accredited Solar Design & Installation for Developers, Businesses & Homes
Since 2015, Flint Energy has been designing, supplying and installing Solar PV and battery storage systems for residential, commercial and development projects across the UK.
We combine considered system design with accredited, professional installation to deliver solar solutions that improve EPC ratings, reduce energy costs and provide long-term performance.
Solar is more than panels on a roof. Correct sizing, inverter selection, battery integration and electrical infrastructure planning all determine how well a system performs. Our approach ensures every installation is technically sound, compliant and built to deliver measurable results.

Solar & Battery Brands We Work With & Install
Who We Design & Install Solar For
-
Solar for Developers
Since 2015, we have supported development projects by integrating solar early in the design process. Our solar installations can:
✔ Improve SAP calculations
✔ Strengthen EPC ratings
✔ Support Part L compliance
✔ Reduce reliance on excessive fabric upgrades
✔ Enhance scheme marketabilityWhen included at design stage, installation becomes more efficient and cost-effective.
-
Solar for Commercial & Industrial Buildings
For commercial architects and property owners, solar provides:
✔ Reduced operational overhead
✔ Predictable energy pricing
✔ Improved ESG credentials
✔ Greater control over long-term energy exposureAt Flint, we design systems around actual load profiles to maximise self-consumption and minimise unnecessary export.
-
Solar for Homeowners & Landlords
We provide straightforward guidance on:
✔ System size
✔ Battery options
✔ Expected savings
✔ Smart Export Guarantee (SEG)
✔ Integration with heat pumps and EV chargersOne of the main reasons homeowners choose Flint for solar is because our process is clear, transparent and focused on long-term value.
// Why Work With Us
Why Solar Needs to Be Designed - Not Just Installed
With more than a decade of renewable delivery experience, the team at Flint understand that solar performance depends on more than panel count.
System output, self-consumption levels and financial return are influenced by:
✔ Roof orientation and shading
✔ Structural suitability
✔ Inverter configuration
✔ Electrical infrastructure capacity
✔ Grid connection limits
✔ Battery sizing
✔ Future expansion planning
Flint Energy will assess all these factors before installation begins, ensuring your system is properly engineered from the outset.
// Why Work With Us
Integrated Solar, Heat Pumps & Smart Systems
Because we design and install low-carbon heating systems as well, we ensure solar integrates seamlessly with:
✔ Air Source Heat Pumps
✔ Underfloor heating
✔ EV charging
✔ Smart energy management
This creates cohesive, future-ready energy systems rather than disconnected technologies.

Frequently Asked Questions About Solar
Still have questions about solar or batter storage? Our team is happy to provide clear, practical guidance tailored to your project.
-
Yes. Flint Energy designs, supplies and installs Solar PV and battery storage systems using qualified engineers and accredited standards. We manage the process from feasibility and system design through to installation, commissioning and certification.
-
The required roof space depends on your energy demand and target system size. As a guide, a typical residential 4kW system requires approximately 20–25m² of suitable roof space. We assess orientation, pitch, shading and structural suitability before confirming capacity.
-
Yes. Solar PV can significantly improve SAP calculations and EPC outcomes, particularly when integrated at design stage. For new developments, early solar strategy can support Part L compliance and strengthen overall energy performance.
-
Most modern Solar PV panels carry performance warranties of 25 years or more. Inverters and batteries typically have shorter warranties (often 10–15 years depending on manufacturer). We specify reliable brands designed for long-term performance.
-
Payback varies depending on system size, usage profile, export rates and electricity costs. Residential systems often see payback within 6–10 years, while commercial installations can achieve shorter returns depending on daytime energy demand.
We provide realistic yield and savings projections before installation.
-
Yes. We support grid connection processes and liaise with the relevant Distribution Network Operator (DNO) where required to ensure your system complies with connection regulations.
-
Yes. Installing solar during the construction phase can reduce costs, particularly when scaffolding is already in place. Early planning also ensures electrical infrastructure and cabling routes are correctly integrated.
-
Solar PV systems require minimal maintenance. Occasional cleaning and periodic system checks help ensure optimal performance. We can advise on ongoing maintenance where required.
-
Yes. Solar integrates effectively with Air Source Heat Pumps, underfloor heating systems and EV charging infrastructure. When designed properly, this combination improves overall energy efficiency and long-term cost savings.
