Project Overview
Client: Chilton Estate
Location: North West of Hungerford, North Wessex Downs
Property Type: Farm and Tenanted Properties on Estate
Installer: ProStar Energy
System Size: 111 kWp across two installations
Key Feature: Sub-metering installed for tenant billing
The Challenge
Chilton Estate, a large farm and tenanted property in the heart of the North Wessex Downs, was looking to reduce operational costs and increase energy efficiency across its estate buildings.
With multiple tenants occupying the property, the estate required a renewable energy solution that could also allow for accurate energy monitoring and individual tenant billing.
The Solution
ProStar Energy delivered a tailored solar PV solution with two separate systems installed on the estate, alongside full sub-metering capability. This enabled the landlord to effectively monitor energy usage per tenant and bill accordingly — a vital feature for multi-occupancy sites.
✅ System One Installation
- Capacity: 63 kWp
- Cost: £37,781
- First-Year Savings: £13,258
- Estimated Payback: 2 years 10 months
- Carbon Offset: 13 tonnes CO₂ annually
✅ System Two Installation
- Capacity: 48 kWp
- Cost: £29,339
- First-Year Savings: £11,659
- Estimated Payback: 2 years 6 months
- Carbon Offset: 12 tonnes CO₂ annually
Key Benefits Significant Financial Return
Combined, the two systems are projected to deliver over £24,000 in savings during the first year alone, with both achieving a full return on investment in under three years.
Environmental Impact
The installations will collectively reduce 25 tonnes of CO₂ emissions per year, supporting the estate’s sustainability goals and contribution to the UK’s net zero targets.
Designed for Tenanted Properties
One of the standout features of this project was the integration of sub-metering technology. This allows the landlord to:
- Monitor solar energy usage per tenant
- Bill tenants individually for their share of the energy produced
- Improve transparency and energy efficiency across the estate
This approach makes solar power a viable and attractive option for landlords of multi-tenanted properties who want to reap the benefits of renewable energy while ensuring fair and accurate billing.
Client Outcome
The Chilton Estate now enjoys lower energy costs, a strong return on investment, and a reduced carbon footprint — all while offering tenants sustainable energy benefits with transparent sub-metered billing.
