Solar PV
Rooftop solar PV is one of the most straightforward ways for a manufacturer to cut electricity costs. For sites with significant daytime demand, a well-designed system will cover a meaningful proportion of consumption directly from generation, reducing the volume of electricity purchased from the grid.
Pro Enviro designs solar PV systems for manufacturing sites, manages the full installation process with MCS-accredited partners, and provides the half-hourly data analysis needed to size a system accurately against your actual demand profile. We work on installations from small commercial systems up to 1.5 MWp.
INDICATIVE PERFORMANCE FIGURES
How the numbers work
The financial case for solar rests on self-consumption - the proportion of generated electricity used on-site rather than exported. For manufacturers with strong daytime demand, self-consumption rates of 85 to 95% are typical. At current electricity prices, a well-matched system can achieve payback in four to six years and deliver significant returns over its 25-year operating life.
What we do
Every installation starts with your half-hourly consumption data. We analyse twelve months of metered data to understand when your site draws electricity and how closely that profile aligns with the solar generation curve. This determines the right system size, expected self-consumption rate, and financial return.

Is solar right for your site?
Solar PV works best for sites where electricity demand is concentrated in daytime hours. Manufacturing operations that run standard day shifts are typically well matched. Sites with the following characteristics are usually strong candidates:
- Significant annual electricity consumption, generally above 250,000 kWh per year
- Daytime-dominant demand profile, with peak load between approximately 07:00 and 16:00
- Available south, east, or west-facing roof area in reasonable structural condition
- Electricity unit rates above the current market average
BATTERY STORAGE
Where a site exports a significant proportion of its solar generation, or where demand shifts outside peak solar hours, battery storage can improve the economics of an installation. We assess whether storage makes sense for your specific load profile and incorporate it into the system design where it does.
