Solar follows useful demand
The useful solar fraction depends on daytime demand, operating days, seasonal behaviour, available area, network limits and how much export or curtailment the site can tolerate.
SOLUTION / SOLAR + BESS
Renewables that work inside the power system.
Solar and battery storage deliver the most value when they are matched to the load profile, dispatch rules and reliability requirement rather than treated as standalone equipment.
Storage has two dimensions
Battery power in kW or MW determines how much instantaneous support the system can provide. Battery energy in kWh or MWh determines how long that support can be sustained. Both must be engineered.
Dispatch controls the economics
The operating logic decides whether storage supports peaks, reduces generator loading, improves power quality, shifts solar energy or provides resilience. The best configuration depends on the commercial objective.
ENGINEERING BASIS / PUBLIC NOTE
Built from operating questions, not equipment catalogues.
This page explains the engineering logic used to frame an early power decision. Final sizing, commercial terms and detailed design depend on verified project data, site conditions and formal engineering work.

FIRST DECISION BASIS
Inputs that materially change the answer.
These are the early inputs Mergen would normally test before treating a configuration as a credible project basis.
01Daytime load profile
02Peak and critical demand
03Available solar area
04Battery duty and duration
05Existing grid or generation
06Energy and fuel cost
PROJECT QUESTIONS
Questions owners and project teams ask.
What is the difference between battery kW and kWh?
kW describes how much power the battery can provide at one moment. kWh describes energy and therefore contributes to how long that output can be sustained. Both are required for proper sizing.
Can battery storage replace all firm generation?
That depends on load size, required duration, recharge opportunity, reliability requirement and economics. For many industrial systems, storage works best as one part of a wider architecture rather than as an automatic replacement for every firm source.
How is solar capacity selected for an industrial load?
Useful solar capacity depends on daytime demand, operating days, available area, network limits, curtailment tolerance and how solar interacts with generators, storage or grid supply.
What determines battery payback?
Savings depend on the duty the battery performs, energy price differences, generator efficiency, solar utilisation, cycling frequency, losses, degradation, maintenance and the installed commercial cost.
START WITH THE LOAD
Bring the operating problem.
Send the State or FCT, demand, operating hours, current supply and reliability requirement. Mergen can use that as the first engineering basis.
