Solar suitability in West Lothian

Do solar panels work in the Scottish climate?

Yes. Modern solar panels generate electricity from daylight, not direct sunshine, so they produce meaningful power even on overcast days. West Lothian's position in the central belt gives long daylight hours in summer — from around 4am to 10pm in midsummer — which means strong generation for six months of the year. Panels still produce electricity on winter days, though output is lower.

What roof orientation is best for solar?

South-facing roofs generate the most total electricity across the day. East-facing roofs generate more in the morning, and west-facing more in the afternoon and evening. East-west arrangements are increasingly popular because they match when most households use electricity — morning and evening — which means you consume more of what you generate. We assess orientation during your survey and advise on the best layout.

Can solar panels go on a slate roof?

Yes. Slate roofs, common on older properties around Linlithgow and Bathgate, can accommodate solar panels using a specialised flashing system that maintains weatherproofing. We inspect the slate condition during your survey — if slates are fragile or the structure needs attention, we will tell you before quoting.

My roof is shaded — can I still have solar?

Partial shading does not necessarily rule out solar. We can use optimisers or microinverters that allow each panel to operate independently, so one shaded panel does not reduce the output of the whole array. During your survey we identify shading from chimneys, trees and neighbouring buildings and design around it. If shading is too severe, we will tell you honestly.

Battery storage

What does a home battery do?

A home battery stores the surplus electricity your solar panels generate during the day so you can use it in the evening and overnight. This means you consume more of your own generation rather than exporting it to the grid, which for most West Lothian households makes solar significantly more useful — especially if you are out at work during peak generation hours.

Can I add a battery later?

Yes. We can install a battery as a retrofit if you already have panels. However, installing panels and a battery together in one visit is usually more efficient and avoids a second installation appointment. We will quote for whichever option suits you.

How long does a battery last?

Modern home batteries typically come with a warranty of around 10 years and are designed for thousands of charge cycles. Battery capacity gradually reduces over time, just like a phone battery, but at a slow and predictable rate. We will discuss warranty and expected performance with your quote.

Inverters and system design

What is an inverter and why does it matter?

The inverter converts the direct current (DC) your panels produce into the alternating current (AC) your home uses. It is a critical component — a well-chosen inverter ensures you get the most from your panels. We use modern string inverters with optimiser or microinverter options where shading or roof layout requires them.

Can I see how much my panels are generating?

Yes. Every system we install includes a monitoring app or online portal, accessible from your phone or computer. You can see real-time generation, battery charge level, and home electricity consumption. Many homeowners find this one of the most satisfying parts of having solar — watching the electricity flow.

Installation and process

How long does installation take?

A typical residential solar PV installation is completed in one to two days. Adding a battery may extend this slightly. Scaffolding is erected the day before and removed after the installation is signed off. We give you a clear timeline with your quote.

Do I need to be home during installation?

Yes, someone should be home for access — the team needs to reach the loft and the area around your consumer unit. We will tell you exactly what access is needed when we schedule the installation.

Is the installation MCS-certified?

Yes. We install through MCS-certified partners, which means your installation is properly accredited and registered. This is important for any future requirements and gives you confidence that the installation meets industry standards.

Costs, VAT and finance

Is there VAT on solar panels?

The UK government currently applies 0% VAT to the supply and installation of solar panels and battery storage on residential properties until 31 March 2027. The quote we send you is the full amount you pay — no VAT is added.

Can I spread the cost?

Loans available, subject to status. We can discuss finance options after your survey and will explain the terms clearly so you can decide whether paying upfront or spreading the cost is right for you.

Is the survey and quote really no-obligation?

Yes. We arrange the survey, assess your home, send a written quote, and you decide whether to proceed. If you choose not to go ahead, there is no charge and no pressure. We believe in honest advice — if solar is not right for your home, we will tell you.

Frequently asked questions

Do solar panels work in winter in West Lothian?

Yes, but output is lower. Panels generate from daylight, so they still produce electricity on short winter days, just less than in summer. Most generation happens from April to September, with the long daylight hours of the Scottish summer.

Will solar panels damage my roof?

No. Panels are mounted on a rail system fixed to your roof structure. For tiled roofs, tiles are lifted and replaced carefully; for slate roofs, a flashing system maintains weatherproofing. A properly installed system does not compromise your roof's integrity.

How do I know if my roof is suitable?

We assess this during your no-obligation survey. We check orientation, pitch, shading, structural condition and roof size. Most West Lothian roofs are suitable, but we will tell you honestly if yours is not a good fit.

Can I run my home entirely on solar?

In summer, a well-sized system with a battery can cover most of a typical household's electricity needs during daylight hours and into the evening. In winter, you will still draw from the grid. Solar reduces your reliance on the grid rather than eliminating it entirely.

Do I need planning permission for solar panels?

Most domestic solar installations in West Lothian do not require planning permission as they fall under permitted development. Exceptions include listed buildings and some conservation areas. We will advise if your property has any constraints.

What maintenance do solar panels need?

Very little. There are no moving parts. Rain cleans the panels in the Scottish climate, though occasional manual cleaning can help. We are available after installation if you have any questions or concerns.
