Build Your Solar System

Tools & Tech System Builder

Plan your solar system

Create an indicative UK home-solar setup, keep the whole system in one shopping plan and see what is still missing before you request an installer quote.

Important: this is a planning and buying organiser, not an electrical design approval. Electrical compatibility is not validated. Final panel layout, inverter sizing, battery compatibility, protection, DNO requirements and installation must be confirmed by a suitably qualified installer.

1. Tell us what you are trying to build

Starting point: choose your requirements above, then create a plan. You can change every recommended quantity or product afterwards.

2. Complete the system

Enter exact products as you research them. Add the product name, quantity, expected price and buying/source link. Your plan saves in this browser on this device.

Purchase plan: add product/source links above, then press “Buy this setup”. Valid links are grouped by website. Manufacturer pages, retailer pages and tracked affiliate links remain different destinations; no combined basket is created.

3. Research the exact parts

Buying safeguard: do not assume two products are electrically compatible because both appear in a shortlist. Ecosystems, battery communications, inverter firmware, backup gateways and installer requirements can be brand- and model-specific. The final system should be approved as one design.

Research your solar system: compare solar panels, inverters, home batteries, smart energy and the Powerwall 2 safety notice, or return to Build Your Setup.

Compare equipment before requesting a solar quote

Use the builder to organise candidate equipment, then compare the exact panel wattage and variant, inverter phase and power rating, battery capacity, compatible monitoring and any backup or installation accessories. Our linked guides provide specifications and buying research, not a live multi-retailer checkout or an installed-system quotation.

Important: panel, inverter, battery, protection, grid-connection and installation requirements depend on the property and location. Check system compatibility and seek an appropriately qualified installer for design, compliance and a complete written quotation. Affiliate or manufacturer links, where present, are disclosed and do not substitute for installation advice.
