Solar and energy systems, designed properly.
TopBytes provides independent solar, battery-storage and EV-charging consultancy for homes and businesses. We take you from the first feasibility conversation to a full system design and specification you can hand to an installer with confidence. We don't sell panels, so our advice is in your interest.
From feasibility to optimisation
Advisory & feasibility
An honest assessment of what solar and storage can realistically do for your property or site. It covers expected generation, savings and payback, and the pitfalls to avoid before you spend anything.
System design
Sizing and layout of solar arrays, battery storage, inverters and EV charging, tailored to your usage, your roof or site and your budget. The design is built to perform, not just to fit.
Specification
A clear, installer-ready specification of components, ratings and configuration. You can compare quotes like for like and know exactly what you're buying.
Tariff & optimisation
Getting the most from your system once it's installed: smart tariff selection (including Octopus tariffs), battery scheduling and monitoring, often integrated with Home Assistant for full visibility and automation.
Homes and businesses
Residential
Homeowners who want solar, battery and EV charging that actually saves money and works the way they expect. Our solar, battery & EV case study shows real-world numbers.
Commercial
Businesses and sites that want to cut energy costs, add resilience and make a credible, well-specified investment case.
