Paisley solar questions, answered

Yes. Panels generate electricity from daylight, not direct sunshine. Output on an overcast day is lower than in full sun, but it is not zero. Scotland's cooler temperatures actually improve panel efficiency. Paisley has kept its own daily weather record since 1884 at the Coats Observatory on Oakshaw — the data shows the town gets enough daylight to make solar viable on most south-, east- or west-facing roofs. A south-facing 4kWp system here produces around 3,300–3,800 kWh a year.

A south-facing 4kWp system produces around 3,300–3,800 kWh a year in Paisley. East- or west-facing roofs produce roughly 15–20% less. These are typical ranges, not a promise — actual output depends on shading, roof pitch and local conditions. Projected output is confirmed at survey.

Jinko Tiger Neo panels with a SolarEdge HD-Wave inverter. The SolarEdge system uses panel-level optimisation, which reduces the impact of partial shading — relevant on Paisley roofs with dormers or chimney stacks. Warranty and guarantee terms are confirmed in writing on your quotation.

Usually not. Most domestic installations are permitted development. However, if your property is in a conservation area — Oakshaw, the Abbey and town centre, Castlehead, or the mill conservation areas — or is a listed building, panels on a visible elevation may need planning or listed-building consent from Renfrewshire Council. We check this before a survey is booked.

You need consent from all roof owners, which is the most common reason a Paisley enquiry cannot proceed. If you live in a flat in a tenement or converted mill building, the roof is almost certainly shared. Solar panels on that roof need the agreement of the other owners through the factor or owners' association. We check this before booking a survey rather than wasting anyone's time.

Yes, every solar installation requires notification to SP Energy Networks (SP Distribution), the network operator for Renfrewshire. The G98 or G99 notification and all DNO paperwork are handled on your behalf as part of the standard process.

Yes. We install through MCS-certified partners, who handle the G98 or G99 notification to SP Energy Networks, the MCS certification, and the paperwork you need to register for the Smart Export Guarantee. You do not need to contact SP Energy Networks yourself.

Yes. A battery can be retrofitted to an existing system. Compatibility with your current inverter and wiring is checked at survey. Priced at survey — the cost is confirmed on your written quote, and 0% VAT applies to batteries until 31 March 2027.

A Solar iBoost diverter uses surplus solar generation to heat your hot water instead of exporting it to the grid. It is the one part of a solar system that works on your hot water rather than your electricity use. We advise at survey whether it suits your setup.

Yes. A battery can be retrofitted to an existing system. Compatibility with your current inverter and wiring is checked at survey. 0% VAT applies to batteries until 31 March 2027.

Priced at survey. Every home is different, so the cost of solar panels, a battery or both is confirmed on your written quote after a full property survey. 0% VAT applies to solar panels and batteries until 31 March 2027.

There is no set age limit, but the roof covering needs to be in sound condition. If slates or tiles need significant repair or replacement, that should be done before panels are fitted — it is much harder to re-roof under panels later. Roof condition is assessed at survey.

For many homes with solar panels, it is worth considering. Paisley's latitude means long summer days produce surplus electricity and short winter days produce a deficit. A battery shifts the summer surplus to the evening and enables overnight charging on off-peak tariffs in winter. Without solar, a standalone battery is usually only worth considering if you are on a time-of-use tariff. We talk through whether it suits your household at survey.

The primary battery is the Duracell Dura5. Tesla Powerwall 3, Pylontech US5000 and Fox ESS are alternatives depending on capacity and installation requirements. Warranty and guarantee terms are confirmed in writing on your quotation.

Yes, a heat pump can replace a gas, oil or LPG boiler. A heat loss survey checks insulation, radiators and hot water needs so the system is sized to your home. We install through MCS-certified partners.

For many off-gas homes in rural Renfrewshire with reasonable insulation, a heat pump is worth a survey. Oil and LPG fuel costs can be volatile, which is why many owners consider a heat pump when the boiler is due for replacement.

Usually, yes. Most home insurance policies require you to notify your provider of any material change to the property, which can include a solar panel or battery installation. Check with your own provider. You receive the installation documentation you need.
