Solar Panel Installer Widnes, an independent guide / Guides

All the Widnes solar guides

The guide is arranged around the three questions a Widnes household meets in order: can my roof take panels, how will they be connected, and what will it cost and who should fit them. Start wherever your question is.

Export limits

The worst case for a capped system, and why the real loss is lower.

Getting paid for exports

Certificates, meters and choosing an export tariff.

Choosing an installer

Registers, the visit and reading the quote.

After switch-on

Papers, monitoring and upkeep once the panels are working.

Where to start

If you have a quote in front of you, open the connection checker with the quote's panel count, panel wattage and inverter model to hand: it takes a minute and tells you whether the firm will be notifying the network after switch-on or applying first, which affects the timetable. Then read choosing an installer before you sign.

If you are only starting to think about it, begin with the roof. Homes across Widnes shows what kind of houses each ward has and what that tends to mean, and Victorian terraces covers the older streets around Appleton, Newtown and Simm's Cross in detail. The money pages come after that, once you know roughly how many panels the roof could take.

Why so much about the grid?

Most solar guides stop at the roof and the price. In practice the inverter and the connection decide a surprising amount: whether a battery can be added without an application, how long the job takes, and whether part of the output is held back by a limit. Widnes has its own reason to pay attention, too: Halton's 2010 infrastructure plan recorded constraints in the electricity network at Widnes Waterfront. The figures on these pages come from PVGIS hourly data for the town, so you can judge the trade-offs before the installer makes them for you.
