ANTA technical resource

See the system, not only the equipment.

A renewable-energy system is an architecture of flows: resource, conversion, protection, grid, loads, storage, backup, monitoring and operating rules.

!

Diagrams explain a principle. Any application requires analysis of the site, use, climate, local rules and operating conditions.

Understand how it works

From principle to technical decision.

Each stage shows what engineering must observe, calculate, coordinate or verify.

01

Describe the loads

Establish consumption, schedules, peaks, seasonality and criticality. The load profile comes before sizing.

02

Characterise the resource

Use location-appropriate weather data and assess orientation, tilt, shading, temperature, dust, wind and salt exposure.

03

Select the architecture

Compare self-consumption, export, hybrid operation, partial autonomy, microgrid and targeted backup.

04

Define control logic

State when to supply, charge, discharge, shed, back up, recharge from grid or generator and raise alarms.

05

Design for life

Plan access, cleaning, ventilation, protections, spares, warranties, cybersecurity, maintenance and replacement.

Design principles

What truly changes project quality.

P01

Use before capacity

More panels do not fix a poorly understood demand profile.

P02

Energy and power

Battery energy capacity and instantaneous power answer different questions.

P03

Load priorities

Backup must distinguish vital, priority, deferrable and shed-able loads.

P04

Continuous measurement

Monitoring should reveal generation, consumption, state of charge, alarms and drift.

Decision support

The right questions before selecting.

These answers provide direction. They do not replace surveys, sizing or site validation.

01

Is a battery always required?

No. It should meet a defined purpose such as continuity, time shifting, peak limitation or autonomy.

02

Does solar work during a grid outage?

A conventional grid-tied system may stop for safety. Maintaining selected loads requires a designed backup architecture and often storage.

03

Can annual output be predicted from kWp alone?

No. Location, orientation, shading, temperature, system losses, availability and operation all matter.

Learning caseIllustration — not a client reference

Learning case — shop exposed to outages

The shop needs lighting, till, communications and refrigeration during outages.

  1. Measure power and duration
  2. Classify load criticality
  3. Define a shedding sequence
  4. Compare battery, PV-battery and hybrid generator options
  5. Test transfer and actual autonomy
Useful autonomy comes from load selection and operating strategy, not from choosing a battery in isolation.

Frequently asked questions

Clear answers without oversimplifying.

01How many panels are needed?

Consumption, schedules, area, shading, climate, objectives and architecture are required.

02How long will a battery last?

Technology, temperature, depth and number of cycles, power, BMS and operation determine life.

03Does cleaning matter?

Yes. Dust, salt or organic deposits reduce output and can create hot spots.

04Can PV, grid and generator be combined?

Yes, with defined priorities, interlocks, protection, control and ownership of commands.

05How is performance checked?

Separate metering, availability indicators, tests and comparison of measured and weather-adjusted expected output.

ANTA perspective

A clear technical position.

Capacity is not selected in isolation. Uses, schedules, criticality, grid quality, ageing and operating strategy define the system.
