Question 1

What is Solar PV?

Accepted Answer

PV stands for Photo-Voltaic (light-to-electricity). Solar PV panels convert any light (not just direct sunlight) into electricity, so they still generate power on cloudy days—just less when it's dimmer. The basic physics dates back to the 19th Century, but modern panels are far more efficient and affordable.

Question 2

How much do solar panels cost in West Wales?

Accepted Answer

As an indicative guide, a typical 4 kW domestic solar system is around £4,000 installed (inc 0% VAT), a 6 kW system around £5,400 and an 8 kW system around £6,400. Adding battery storage alongside a new solar install is around £2,000 for ~5 kWh or ~£3,000 for ~10–12 kWh; retrofitting to existing solar starts from around £1,500 for 5 kWh. Every job is priced individually after a free site survey — we provide no-obligation quotes tailored to your property.

Question 3

What does an inverter do?

Accepted Answer

An inverter converts the DC electricity produced by your PV panels into the AC electricity used by your home and the grid. Choosing the right inverter and siting it correctly (e.g. in a cool, accessible space rather than a hot loft) maximises performance and longevity.

Question 4

How much electricity will my PV panels generate?

Accepted Answer

A typical 4 kWp system on an unshaded, south-facing roof in Pembrokeshire can produce around 3800 kWh per year. East- or west-facing roofs still yield roughly 3300 kWh. The average UK household uses about 3500 kWh annually, so you could cover most or all of your needs, depending on usage patterns.

Question 5

How much will I save on my bill?

Accepted Answer

Using the latest PV 3D modelling software, we factor in panel and inverter performance, shading, roof orientation and local weather to forecast your annual output. Then we translate that into financial savings based on your tariff and typical consumption.

Question 6

What happens when there's not enough light?

Accepted Answer

Your system simply draws the remainder from the grid as normal. Even on overcast days, your panels will still contribute something. Solar panels work well in Wales, even on cloudy days, as they generate electricity from daylight, not just direct sunlight.

Question 7

What happens if my panels produce more than I'm using?

Accepted Answer

Any surplus is automatically exported and credited by your energy supplier. We can discuss and advise which tariffs past customers have provided the best feedback for.

Question 8

What size system can I fit on my roof?

Accepted Answer

We use Open Solar and PV-Sol to create a 3D model of your property and test panels from over 400 manufacturers. Whether you need 3 kWp or 10 kWp (or more), we'll find the optimal layout.

Question 9

How long does installation take?

Accepted Answer

Domestic installs typically finish in two days (up to five for large roofs). Commercial projects vary by size and complexity. All work is carried out by our in-house team: an experienced roofer, a labourer and a certified electrician.

Question 10

Do I need planning permission for solar panels in Wales?

Accepted Answer

Most domestic installs are 'permitted developments' with no planning needed—unless you're on a listed building, in a conservation area facing a highway, have panels protruding over 200 mm, or are mounting on the ground. We'll advise if any special consents are required.

Question 11

How long do solar panels last?

Accepted Answer

Average degradation is ~15% over 25 years; top-tier panels lose as little as 2.5%. Solar panels typically last 25-50 years with minimal maintenance. We provide 25-year performance warranties on all our solar installations in Pembrokeshire, Carmarthenshire, and Ceredigion.

Question 12

What happens in a power cut?

Accepted Answer

For safety, your inverter shuts off when the grid goes down. If you require backup power, ask about battery-storage options that can island your home during outages.

Question 13

Do panels need a south-facing roof?

Accepted Answer

No—east/west setups still achieve about 86% of a south-facing system's yield. We can optimize any roof orientation for maximum performance.

Question 14

What about shading?

Question 48

What is a battery storage system and how does it work?

Accepted Answer

A battery storage system stores excess electricity generated by your solar PV panels (or imported from the grid) and releases it when you need it—such as in the evening or during peak-rate periods. The system's inverter/charger manages charging, discharging and grid interaction automatically.

Question 49

How does battery storage increase self-consumption?

Accepted Answer

By storing surplus solar generation that would otherwise be exported, a battery lets you use your own green energy later on. This reduces the amount of electricity you buy from the grid and maximises the value of every kWh your panels produce.

Question 50

How much battery capacity do I need?

Accepted Answer

Capacity (kWh) depends on your household's evening and overnight usage, as well as your goals (e.g., maximising self-consumption vs. backup power). We analyse your consumption patterns and simulate different battery sizes in our PV-Sol models to recommend the optimal capacity.

Question 51

How long will my battery last?

Accepted Answer

Most manufacturers guarantee around 6,000 cycles or 10 years of performance retention (often > 70% capacity remaining). In real-world terms, that's typically 15–20 years of usable life, depending on how deeply and often you cycle the battery.

Question 52

Can I install battery storage without solar panels?

Accepted Answer

Yes. A grid-charged battery system can be installed independently to take advantage of time-of-use tariffs (charging when rates are low, discharging when high) or provide uninterruptible power during outages.

Question 53

Can I retrofit battery storage to an existing PV installation?

Accepted Answer

Yes. As long as your current inverter is compatible or can be supplemented by an add-on battery inverter, you can retrofit storage. We'll assess your inverter's specifications, available AC/DC coupling options, and whether a hybrid solution or separate battery inverter is more suitable for your system.

Question 54

How does a hybrid inverter manage both solar PV and battery storage?

Accepted Answer

A hybrid inverter seamlessly directs solar-generated DC power either to your home, to charge the battery, or to export to the grid. When solar production exceeds your immediate demand, it prioritises charging the battery before exporting, and during low-sun periods it will draw first from the battery, then from the grid if needed.

Question 55

How much do battery storage systems cost?

Accepted Answer

As an indicative guide, adding a battery to an existing solar system starts from around £1,500–£2,000 for ~5 kWh, or £2,000–£3,000 for ~10 kWh (including the inverter where needed). Installed alongside new solar, ~10–12 kWh is around £3,000. Standalone battery-only systems are priced per job. We offer flexible options from 5kWh to 15kWh+ systems, all quoted after a free survey.
