Renewable Energy Installations
Solar PV, battery storage, wind turbines & solar-aware EV charging — designed, installed and commissioned across the South West
Solutions Ltd
Your Complete Renewable Energy Specialist
We design and install integrated renewable energy systems that combine solar PV, lithium battery storage, small-scale wind, and smart EV charging — all working together through a single hybrid inverter. Whether you want to slash your electricity bills, prepare for a heat pump, or take a remote Dartmoor longhouse fully off-grid, we cover the entire South West and project-manage every element from planning to commissioning.

Wind Turbines
Domestic, agricultural and commercial wind power. G98/G99 DNO approval included. Best for coastal & high-ground sites.
From £6,500 plus VAT →
EV Chargers
Solar-aware EV chargers (Zappi, Ohme, Andersen) that charge from surplus solar. OZEV grant approved.

Why Combine Technologies?
The Hybrid Advantage
A modern hybrid inverter (Sunsynk, GivEnergy, Victron MultiPlus, SMA Sunny Boy Storage) is the brain of a serious renewable system. It manages solar input, wind input, battery charge/discharge, grid import/export and EV charger demand — all in real time, all optimised for the cheapest energy outcome.
Set up correctly, your system will charge the battery from solar by day, top up from cheap-rate Octopus Go/Agile by night, divert surplus to your EV and hot water cylinder, and only ever pull peak-rate grid electricity as a last resort. We've seen Devon households drop from £3,200/year to under £400/year on combined electricity and petrol with this exact setup.
Frequently Asked Questions
What's the best renewable system for a typical Devon home?
For most 3-4 bedroom Devon homes, the optimum system is 4-6kW of solar PV + 10kWh of lithium battery + a Zappi or Ohme solar-aware EV charger. This typically reduces grid imports by 75-85% and costs £12,000-£18,000 plus VAT installed. Coastal or high-ground properties (Exmoor, North Devon, Lizard) often benefit from adding a small wind turbine for winter generation when solar yields drop.
Are renewables still worth it without the Feed-in Tariff?
Yes — and arguably more so. The Smart Export Guarantee (SEG) replaced FiT and currently pays 5-15p/kWh for exported surplus. With electricity prices at 27-30p/kWh, self-consumption is where the real savings are. A typical 5kW solar + 10kWh battery system pays back in 6-9 years with a 25-year asset life — a 12-15% effective annual return.
Do I need an MCS-certified installer?
MCS certification is required to claim the Smart Export Guarantee (SEG) and any current government grants (ECO4, BUS for heat pumps). Our installations are designed to MCS standards and we work with MCS-certified partners on the design sign-off so you remain eligible for all schemes.
Can I go fully off-grid in Devon?
Yes — and we have done it for properties on Dartmoor, Exmoor and across remote Cornwall. A typical off-grid system is 6-10kW solar + 1-3kW wind + 20-30kWh lithium battery + a small LPG or diesel generator for January/February top-up. Budget £25,000-£45,000 plus VAT depending on consumption profile. We design every system around your actual annual kWh usage, not generic templates.
How long does a renewable installation take?
Solar-only: 1-2 days. Solar + battery: 2-3 days. Full hybrid solar+wind+battery: 5-10 days plus a separate day for DNO commissioning. Wind turbine mast installation depends on civils (typically a separate week). We project-manage the whole process from initial survey to grid commissioning.
