Agrivoltaics
Keep the land in production — grazing and cropping continue under and around the panels.
Land that keeps working
Solar doesn't have to take your best fields out of use.
Ground-mount arrays can be raised and spaced so sheep keep grazing and machinery keeps moving. We design around your rotation, your hedgerows and your tenants — so the panels pay and the farm keeps farming.
- Dual-use design: power generation plus continued grazing or cropping
- Raised mounting for livestock and machinery access
- Sited to respect hedgerows, habitats and tenancy agreements
Aftercare
Installed, monitored and supported.
RLW Electrical & Solar doesn't just install systems. Every install is connected to remote monitoring that runs around the clock — tracking performance, identifying issues and supporting long-term system reliability.
- Remote performance monitoring on every installation
- Flags underperforming strings, inverter faults and generation drops
- Supports ongoing system management and long-term output
