From the team behind LMG: Big Green Solar delivers expert Solar PV and Battery Storage solutions for your home.

Big Green Solar is LMG Home Improvements’ dedicated Solar PV and Battery Storage division, delivering MCS-accredited design, installation and maintenance across Wales & West for both private homeowners and social housing providers.

Our engineers have been installing solar since the early days of the UK market and have completed thousands of installations, giving us the technical depth to handle everything from single residential systems to multi-property social housing programmes. We work to the same rigorous standards on every contract, backed by TrustMark and HIES accreditation.

With energy costs rising and solar technology now more capable and cost-effective than ever, we help homeowners and housing providers build long-term energy resilience — from initial site assessment through to installation and ongoing maintenance.

Frequently asked questions about Solar PV and Battery Storage

Why choose LMG Home Improvements for Solar PV and battery storage?2026-01-12T13:43:13+00:00

LMG Home Improvements is and MCS Accredited installer who provide professional Solar PV and battery storage solutions with quality equipment, correct system design, and safe installation standards. We focus on long-term performance, reliability, and helping homeowners maximise savings from their renewable energy system.

Can Solar PV work with other home improvements?2026-01-12T13:42:49+00:00

Yes. Solar PV pairs well with upgrades such as insulation, heat pumps, EV chargers, and smart energy tariffs. Combining measures can significantly improve energy efficiency and reduce overall energy costs.

Is Solar PV safe?2026-01-12T13:49:03+00:00

Yes. When designed and installed correctly by qualified professionals using compliant equipment and protections, Solar PV and batteries are safe and reliable systems.

What maintenance is required for Solar PV and batteries?2026-01-12T13:42:08+00:00

Solar PV requires very little maintenance. Periodic visual checks and performance monitoring are recommended. Batteries are usually maintenance-free, and system performance can be monitored via an app.

Will the installation disrupt my home?2026-01-12T13:41:43+00:00

Disruption is minimal. Most work takes place externally on the roof and internally near the consumer unit/inverter location. Power may need to be isolated briefly during electrical connection and commissioning.

How long does installation take?2026-01-12T13:41:22+00:00

Most Solar PV systems are installed within one to two days. Battery storage installation is typically completed alongside the solar installation, although it can vary depending on electrical works required.

Can Solar PV be installed on any roof?2026-01-12T13:41:03+00:00

Many properties are suitable, but installation depends on roof condition, direction, pitch, shading, and structural suitability. South-facing roofs are ideal, but east/west-facing roofs can still perform very well.

Do I need planning permission for Solar PV?2026-01-12T13:40:41+00:00

Most domestic solar installations fall under permitted development rules, but exceptions apply (for example, listed buildings, conservation areas, or certain roof layouts). A site assessment will confirm requirements.

Will Solar PV work during a power cut?2026-01-12T13:40:17+00:00

Most standard Solar PV systems automatically shut down during a power cut for safety. Some battery systems can provide backup power functionality, but this requires specific equipment and system design.

How long do solar batteries last?2026-01-12T13:39:53+00:00

Battery lifespan depends on the brand, capacity, usage patterns, and operating temperature. Most modern batteries come with warranties based on years and/or cycles (charge/discharge cycles).

How long do Solar PV panels last?2026-01-12T13:39:22+00:00

Solar PV panels are designed to last for decades and typically come with long manufacturer performance warranties. Output gradually reduces over time, but systems commonly continue producing usable energy well beyond warranty periods.

Can Solar PV and battery storage increase my property value?2026-01-12T13:38:55+00:00

It can. Solar PV and battery systems are often seen as desirable upgrades because they reduce ongoing energy costs and improve EPC performance in many cases, which can be attractive to buyers.

What happens to unused solar electricity?2026-01-12T13:38:37+00:00

If you generate more power than you use, the surplus can either be stored in your battery (if installed) or exported back to the grid. Some households may receive export payments depending on their tariff.

Is battery storage worth it on its own?2026-01-12T13:38:12+00:00

Battery storage is most effective when paired with Solar PV. In some cases, batteries can also be charged using off-peak electricity tariffs to lower running costs, depending on your energy supplier and tariff.

Is Solar PV worth it without a battery?2026-01-12T13:37:47+00:00

Solar PV can still be worth it without a battery, especially for households with high daytime electricity use. However, a battery usually improves overall value by storing excess power and reducing evening grid usage.

How much can Solar PV reduce my electricity bills?2026-01-12T13:37:22+00:00

Savings depend on your system size, roof orientation, shading, and how much energy you use during the day. Adding battery storage typically increases savings because more of the energy generated is used within the home rather than exported.

Does Solar PV work on cloudy days or in winter?2026-01-12T13:37:04+00:00

Yes. Solar PV works in daylight and still generates electricity on cloudy days, though output is lower. In winter months, generation is reduced due to shorter days, but the system still contributes to household electricity usage.

Why are Solar PV and battery storage considered a quality home improvement?2026-01-12T13:36:46+00:00

Solar PV with battery storage is considered a premium upgrade because it reduces household energy costs, improves energy independence, adds long-term value, and supports lower carbon living. Batteries also improve performance by making solar energy usable when panels are not generating.

What is battery storage for Solar PV?2026-01-12T13:36:25+00:00

A solar battery stores surplus electricity generated by your solar panels during the day so it can be used later, such as in the evening or overnight. This increases self-consumption and reduces the amount of electricity you need to buy from the grid.

What is Solar PV?2026-01-12T13:36:08+00:00

Solar PV (photovoltaic) is a system of solar panels that converts daylight into electricity for your home. Panels can be installed as roof-mounted systems (fixed above existing tiles) or as in-roof systems (integrated into the roof structure for a lower-profile finish). Solar PV helps reduce reliance on the grid and can lower electricity bills.
