What exactly am I buying?
Ask for panel and inverter model numbers, battery capacity if included, warranty terms and any optional items. The proposed size needs to suit your roof and electricity use.
Quality
Before work starts, you should know what equipment is proposed, where it will go and what you will receive at handover. Here is what to look for in your proposal.
Your installation checklist
Use these questions to compare proposals on the same basis.
Ask for panel and inverter model numbers, battery capacity if included, warranty terms and any optional items. The proposed size needs to suit your roof and electricity use.
Review panel layout, equipment positions, cable routes, access and any disruption during the survey. Ask how the design accounts for shading and your electrical setup.
Ask which documents, monitoring access, commissioning information and support contacts you will receive. Confirm any backup function explicitly; a battery does not automatically provide it.
Equipment options
We use Leapton panels for homes, with GoodWe and Sigenergy inverter and storage options. The proposal names the equipment selected for your property.

Our residential packages use 460 W Leapton panels with a full black finish. Your proposal confirms the model, panel count and roof layout.
Commercial projects may use different panels, as specified for each installation.
Sigenergy equipment is one of our inverter and storage options. Your proposal confirms the model, power rating, storage and any additional functions included.
Optional functions and future expansion depend on the selected model and system design.
GoodWe equipment is another inverter and storage option. The right configuration depends on electricity use, the property and the agreed specification.
The ESA illustration shows a manufacturer product family, not a confirmed package for your home.For cable runs that require containment, we use galvanised steel conduit rather than plastic conduit. It gives the enclosed cables robust physical protection and keeps the visible route neat. Ask us to walk you through the cable route and equipment positions during your survey.
The survey checks your roof, shading, access and electrical setup. It is also your chance to discuss equipment locations before the proposal is finalised. The home survey is free, with no obligation to proceed.
Keep the equipment documents, warranty terms, monitoring guidance and support contacts together. These help you understand the system and explain an issue if you need assistance.
