Rooftop Solar + Storage for Industry: A Roadmap to Cut Energy Costs
For daytime-operating industrial sites, rooftop solar can push self-consumption to 70–95%. Add storage and you can manage shifts and peaks too.
Why it is ideal for industry
Industrial production is usually daytime-heavy, overlapping with solar output. The higher your self-consumption, the less hourly netting affects you. Since businesses may install up to their connection-agreement power, serious rooftop capacity is possible.
The roadmap
- Consumption analysis: map your hourly load profile and its day/evening split.
- Rooftop sizing: design to self-consumption and connection power.
- Storage: if you have shift/evening load, shift midday surplus with BESS.
- Revenue streams: where eligible, evaluate ancillary services and peak shaving.
The cost-saving logic
Savings come from two places: consuming your own generation instead of buying expensive daytime grid power, and avoiding expensive peak hours via storage. In EPİAŞ data, peak (17–22) ~3,375 TL/MWh; drawing from the battery instead of the grid in those hours is a direct cost advantage.
Industrial zones (OSB) potential
The large roofs of organised industrial zones, with high self-consumption potential, are strong rooftop-solar candidates. Egesa runs the whole process under one engineering standard, from feasibility to commissioning.

What self-consumption can industry reach?
Daytime-operating sites can naturally reach 70–95% self-consumption, meaning they are little affected by hourly netting.
How much rooftop solar can a business install?
Unlicensed installed power for businesses can be up to the connection-agreement power; roof area and this power together are decisive.
Is storage essential for industry?
For shift-based or evening-heavy sites, storage increases the cost advantage; with a pure daytime profile, rooftop solar alone delivers strong savings.
