How solar works
MCS, DNO, and SEG – Explained Simply
We Handle the Paperwork. You Save from Day One.
DNO Approvals:
We submit your application to the Distribution Network Operator so your system connects legally
and safely.
MCS Certification:
All EcoGlow installations are fully MCS-certified, which qualifies your system for SEG income.
Smart Export Guarantee (SEG):
Any excess power you don’t use is exported to the grid — and your energy company pays you for it.

Sustainability Callout
An average 3.5kW solar system offsets 1.5 tonnes of CO2 per year.
That’s like planting 75 trees annually — or avoiding 2 return flights from London to Rome
Put in – A Complete Energy Solution This isn’t just solar – it’s about taking full control of how your home uses and pays for energy.
By combining solar panels, battery storage and a smart EV charger, you move away from being fully reliant on the grid and instead start generating and managing your own electricity. During the day, your home can be powered by solar, with any excess stored in the battery ready to be used later in the evening.
This also allows you to charge your car for day-to-day use using solar where possible, alongside cheaper off-peak electricity overnight. The result is a more efficient, future-proof home where you have far greater control over your energy costs, reduced exposure to rising prices, and significantly less reliance on the grid. The example below is based on a typical system using 8 solar panels (approximately 3.6kW), paired with 11.5kWh battery storage and a smart EV charger. This would suit a household using around 5,000–7,000 kWh per year, including electric vehicle usage. A full system of this type, including supply, installation and a fully installed EV charger, would typically be in the region of £9,000–£11,000, depending on roof type, orientation and overall system specification.

Can I install solar without a south-facing roof?
Yes. East- and west-facing roofs perform at 70–85% of optimal.
What happens on cloudy days?
Solar still works – just at reduced output.
Battery storage smooths the curve.
