Sized for mid-size SMEs, hospitality, care homes and retail units with annual demand of 40,000 to 60,000 kWh. For care homes and hotels with significant overnight load, battery storage often forms part of the design from day one.

50kW · 95-110 panelsA 50kW commercial solar system is sized for mid-size SMEs and operationally diverse businesses, from small-to-mid hotels, restaurants and retail units to care homes and small manufacturing operations. It uses 95 to 110 panels across 220 to 280 square metres of roof and suits businesses with annual electricity demand of 40,000 to 60,000 kWh.
For care homes and hotels with significant overnight load, battery storage typically forms part of the design from day one. The system is eligible for the Annual Investment Allowance, business rates exemption to April 2035 and 20% reclaimable VAT, and all paperwork and grid approvals are handled end to end by Solar4Good on your behalf.
Indicative figures for a 50kW commercial system on a typical UK site. Your exact output depends on your roof, orientation, shading and usage, confirmed in a site visit.

Every 50kW system is designed around your site’s demand profile and usage, then installed by the same MCS-certified team that assessed it. Certified under our own MCS registration, no remote sales centre, 3,000+ UK homes and counting.
For businesses using 40,000 to 60,000 kWh a year, a 50kW system covers a large share of daytime demand, and for hospitality and care operations a battery extends that into the evening and overnight.
If your demand is lower a 40kW system may suit; if higher, look at 70kW or above. We size precisely from 12 months of your meter data rather than a template, and design in battery storage and commercial EV charging where they strengthen the case.
We design and install commercial systems across the UK, certified under our own MCS registration. A few recent examples near this scale:
Pick your rough annual electricity use for a starting point, then compare the commercial sizes below. We size precisely from 12 months of your meter data in a site visit.
Larger sites? We install commercial systems up to 150kW and beyond.
You work with a UK-wide commercial team based in Harrow, not a remote sales centre. The person who assesses your roof is directly involved in designing the system, and once it is in we handle MCS certification, SEG export-tariff setup and your monitoring app, so you are never left navigating the process alone.

The questions businesses actually ask about a 50kW commercial solar system.
A 50kW system suits mid-size SMEs and operationally diverse businesses, from small-to-mid hotels, restaurants and retail units to care homes, with annual demand of 40,000 to 60,000 kWh. For sites with overnight load, a battery is usually designed in from day one.
95 to 110 panels across roughly 220 to 280 square metres of roof, sized to deliver 50 kW DC. They fit most mid-size commercial roofs, including corrugated metal, concrete and slate-tile buildings.
Commercial solar is eligible for the Annual Investment Allowance, business rates exemption to April 2035, and 20% reclaimable VAT. With high daytime self-consumption, payback is typically faster than an equivalent residential system.
Yes. Every commercial project starts with a site visit and structural assessment. A qualified engineer reviews roof type and load capacity and, where available, 12 months of half-hourly meter data to design around your actual demand.
Most installations are carried out under our own MCS registration. Further afield we use installers working under our MCS registration, and the certificate and workmanship warranty remain ours. We handle all paperwork, grid approvals, MCS certification and AIA modelling guidance for your accountant.
