Choosing an Upgrade for Your Johnstone Home
Different problems call for different upgrades. If you export most of your generation, a battery or hot-water diverter helps you use more of it. Where demand has grown, for example with an electric car, adding panels may make more sense. If a tree or chimney shades part of the array, optimisers or microinverters can recover lost output.
Preparing for an Upgrade Survey
- Your original MCS certificate or handover pack
- Any tariff or export payment arrangements
- Your current annual electricity use
- Any new appliances increasing demand
- Photos of the roof showing unused space
How Much Does a Solar Upgrade Cost in Johnstone?
Most solar upgrades in Johnstone cost between £500 and £6,000. Simple indoor upgrades are the cheapest, and adding extra panels with scaffolding sits at the top. Bigger combined upgrades can go beyond this range.
Protecting Your Existing Tariff
For FiT systems, the extension is normally kept on a separate meter to protect the original payments. New capacity needs its own MCS certificate to earn Smart Export Guarantee payments.
Do Solar Upgrades Need Permission in Johnstone?
Extra panels on a house roof are usually permitted development, as long as they follow the same rules as the first array. Indoor equipment such as diverters and batteries does not normally need planning permission. The local planning authority for Johnstone is Renfrewshire Council.

Frequently Asked Questions
Here are some practical answers to common questions about this work.
How do I get solar upgrade quotes in Johnstone?
Send one enquiry with your postcode, details of your existing system and what you would like to improve. We can match it with up to four specialists covering Johnstone.
Can old and new solar panels work together?
Yes, but they are usually wired as separate strings, often with their own inverter, because older and newer panels have different electrical characteristics.
Is it worth upgrading an older solar system?
Often, yes. Upgrading builds on the panels, roof fixings and wiring already in place, which is usually much cheaper than a complete new system.
Will an upgrade affect my Feed-in Tariff?
Not if it is handled correctly. Extensions are normally metered separately so the original FiT payments continue, and your FiT supplier must be informed.
