Selecting the right solar installer: There is more to it than just price. An installation needs to be safe, clean and fit properly in your home or business with the infrastructure behind it if something goes wrong. Questions you should ask before signing an agreement:
1) Are you licensed and bonded?
Simply from a due diligence perspective, ask what accreditations they hold and if the company carries insurance for public liability. A good installer will actually put that in writing. For Dorset Solar Panels, contact //solarpanelsdorset.co.uk/solar-panels
2) Which system size would you suggest and why?
Your average consumption, roof space, shading and whether you want to pair it with a battery or EV charger. These are all factors that will impact this decision. A good installer should provide one handy quote explaining the reasoning. Be wary of “one-size-fits-all” packages.
3) Panel brands and Inverter Brands
If other panels are being used, what is the brand of these or do they all have a TIER rating?
Ask to see item names and datasheets. Top brand components can last decades, but the cheaper parts are typically far less rugged and a significant source of pain due to their failure rate. Quality counts.
4) What warranties do I get?
Clarify:
Panel product warranty
Performance warranty
Workmanship/installation warranty
Inverter and battery warranties
Don’t forget to ask what happens regarding warranty claims if the installer should go out of business.
5) What does the quote include?
Check if there is work for scaffolding, bird protection , supervision etc. (are there any sub-contractors) paperwork and grid connections. You want real prices and no hidden extras.
6) What does the timeline look like?
Also inquire on survey dates, how long installation takes and when the system will be commissioned.
