Step 1: Define your goals and check site suitability
Start by clarifying what you want to achieve with a new solar and storage system. Some households prioritise lowering electricity bills, while others want backup power for outages or greater energy independence. Write down your typical daily usage, including when Solar & battery installers in Devon you’re home, and note any major appliances such as electric showers, heat pumps, or EV charging. This helps you choose the right system size and battery capacity rather than relying on a one-size-fits-all quote.
Next, assess whether your property has the physical conditions required for efficient generation. Review roof orientation, roof angle, and the amount of shading from trees, chimneys, or nearby buildings. If you’re unsure, ask an installer to perform a site survey that includes solar access checks, not just a quick measurement from the street. Also confirm whether you have space for outdoor components like inverters and whether there are any access constraints for scaffolding or safe installation routes.
Step 2: Choose compliant components and confirm the installation plan
Use a component checklist to compare proposals in a consistent way. Look for clear details on solar panel type, inverter model, battery capacity, and installation hardware such as mounting systems and isolators. Reliable installers should explain how the inverter will manage Solar panel installer in Exeter energy flow and how the battery will be charged and discharged to match your usage patterns. If a quote is vague, request specifications in writing so you can verify performance claims and warranty coverage.
Confirm that the installer’s plan addresses the electrical and structural side of the job. Ask whether they will upgrade your consumer unit if needed, and whether they will integrate the system with your existing meter arrangements safely. For roof-mounted systems, request information on rail placement, waterproofing approach, and cable routing so you understand how penetration points are sealed.
Step 3: Review paperwork, warranties, and performance expectations
Before signing anything, check that you receive a complete package of documentation. This should include a clear scope of work, product warranties for panels, inverters, and batteries, and workmanship guarantees for the installation itself. Ask how long monitoring is included and what the process is if you need support later, especially if performance appears lower than expected. Make sure the contract clearly states responsibilities for any additional works that might be required after the survey.
Next, validate the expected output and how it will be measured. Request an estimate of annual generation based on your roof conditions and a battery strategy for self-consumption, not just peak output figures. Confirm whether performance will be tracked through an app or portal and whether you’ll receive guidance on interpreting data. You should also ask about system limits such as maximum battery cycling, how firmware updates are handled, and what maintenance checks are recommended to keep the system operating efficiently.

Using this checklist approach helps you compare options fairly and avoid common pitfalls when selecting Solar & battery installers in Devon. By defining goals early, verifying site suitability, and insisting on transparent specifications, you can build confidence that your system will match your property and energy habits.
