Price: £1945.25 Includes 24-hour delivery (excluding weekends and bank holidays).

This kit is designed for the homeowner who wants high-quality, professional-grade hardware without the immediate expense of a full battery storage system. It provides the core “engine” and “fuel” for your home energy independence.

The Inverter: Sunsynk 5kW Hybrid

The Sunsynk 5kW is a legendary workhorse in the renewable industry. While budget inverters exist, Sunsynk is renowned for its robustness and extreme flexibility. It is one of the most widely used and respected designs globally, offering a level of reliability that cheaper “clones” cannot match.

Hybrid Ready: This is a hybrid unit, meaning it is ready for a battery the moment you are.
Dual MPPT: It manages two separate “strings” of solar panels, allowing you to maximize harvest even if your roof has different orientations.
Support: Wind turbine and micro inverters are supported inputs of the inverter

The Panels: Longi 505W Bi-Facial

We have paired this system with Longi, a global leader in solar innovation. These are Bi-Facial panels, meaning they don’t just harvest energy from the top; they capture reflected light from the underside as well.

Increased Yield: When installed with the included mounting system—which provides the necessary clearance and spacing—you’ll see a measurable boost in output compared to standard “one-sided” panels.
3kW Array: This kit provides a 3kW solar array. On an average day, this will generate approximately 12kWh of power. Expect up to 24kWh in the peak of summer and around 3kWh during the shortest winter days.

What’s in the Box (and what isn’t)

This kit includes the core components required for a standard installation. To keep the price low and the choice in your hands, we have excluded the AC cabling and the specific protection (such as an RCBO) required for your home’s consumer unit, as these vary by property.

The Battery Strategy: Scale Smarter, Not Sooner

We have purposefully left the battery out of this initial package. In 2026, energy storage is a personal choice based on your specific “overnight” usage (typically from 16:00 to 09:30).

Our Professional Advice: If you are shopping on a budget, it is often better to hold off than to buy a small 5kWh battery today. Why? Because battery costs do not scale linearly:

Two separate 5kWh batteries often cost the same as a single 15kWh unit.
A 20kWh battery is frequently only a small price jump from a 15kWh one.

By starting with this solar-only kit, you can monitor your actual generation and usage via the Sunsynk app, allowing you to “right-size” your future battery purchase for maximum ROI.
