Cut your energy bills by up to 70% depending on system size, your usage and your property, potentially earn from surplus power via the Smart Export Guarantee (subject to supplier eligibility), and protect yourself from rising energy prices.

0% VAT applies to all solar PV installations until March 2027 — saving typically £500–£1,500 on the total cost.

How it works

Solar PV in four simple steps

1
Panels capture sunlight
Solar panels absorb daylight — even on cloudy days — and convert it into DC electricity.
2
Inverter converts power
An inverter converts DC into AC electricity — the type your home appliances use.
3
Power your home
Your solar electricity powers your home first. Surplus is stored in a battery or exported.
4
Earn from surplus
Export surplus electricity via the Smart Export Guarantee (SEG) and earn money back. SEG eligibility depends on your energy supplier’s requirements and the installation evidence they accept — suppliers normally require an MCS certificate, so please talk to us about the arrangements for your installation.

0% VAT on all solar PV and battery storage until March 2027. Guide prices — contact us for a fixed quote.

Smart Export Guarantee — please read: SEG payments require your energy supplier to accept the installation — suppliers normally ask for an MCS certificate. Eco Care Solutions is not currently MCS certified (re-registration is in progress) and our Heat Pump Go partnership covers heat pumps only, so we cannot currently issue an MCS certificate for a solar PV installation. Please talk to us about what this means for your SEG application before you order.

FAQs

Solar PV questions

Yes — solar panels generate electricity from daylight, not direct sunlight. South Wales receives enough solar radiation to make solar PV an excellent investment. Modern panels are more efficient than ever and generate meaningful electricity on overcast days. Swansea receives around 1,500–1,600 hours of sunshine per year (Met Office).
In most cases, solar panels are permitted development — no planning permission needed. Exceptions apply for listed buildings or conservation areas. We check all planning requirements as part of our survey process.
Most domestic solar PV installations are completed in one day. Systems with battery storage typically take 1–2 days. We handle all DNO notifications and paperwork on your behalf.
Yes — in most cases we can retrofit a battery to an existing solar PV system. Retrofit batteries currently benefit from 0% VAT until March 2027.
Solar PV benefits from 0% VAT until March 2027. Low-income households in Wales may qualify for fully-funded solar through ECO4 or the Warm Homes Programme Wales. The Smart Export Guarantee (SEG) can provide ongoing income from surplus electricity you export, subject to your energy supplier’s eligibility requirements — suppliers normally require an MCS certificate for the installation.
