Solar PV Operations and Maintenance Software

What does solar pv systems software do?

The difficulty in solar PV service is not doing one job — it is running dozens at once without mixing them up. Where each technician is, which job is waiting on a part, which customer has not been called back: leave that in a notebook and in people's heads, and it falls apart as the business grows.

The AsentTime field service module holds all of it in a single work order. A numbered record opens the moment a request arrives, tying customer, address, equipment, reported fault and assigned technician together. Every status change is written to history, so "what happened to that job?" always has an answer in the system.

The second layer is the asset record. In solar PV service, the same equipment is visited many times over the years; knowing what was done before shortens diagnosis and makes recurring faults visible.

Which equipment can you track?

An asset record holds make, model, serial number, asset tag, installation date and both manufacturer and service warranty expiry dates. Equipment can be nested under other equipment, so site-level installations are tracked as a hierarchy.

Equipment commonly tracked in solar PV service:

• Solar panels and string groups

• Inverters and optimisers

• DC and AC boards and protection equipment

• Monitoring and data acquisition systems

• Mounting structures

• Battery storage units

• Transformers and grid connection points

• Cabling and earthing systems

Common jobs and fault types

Defining fault categories makes it possible to report which problems occur how often — the most concrete data you have for stock planning and technician training.

The most frequently opened work order types in solar PV service:

• Planned maintenance and general inspection

• Panel cleaning and efficiency loss

• Inverter faults and error codes

• String loss and cable faults

• Monitoring system connection drops

• Thermal imaging inspection of panels

• Earthing and protection checks

• Installation, commissioning and expansion

How the technician's day gets easier

Technicians see their assigned jobs on their phone: customer name, address, directions, on-site contact and the equipment's history are all to hand. There is no need to call the office for information.

Where a workflow template is defined, the tasks and checklist arrive with the work order. Ticking items off records the work as it happens, and photos and notes can be attached. Recording a part against the work order deducts it from stock automatically.

When a job needs more than one visit — waiting on a part, or needing a second pair of hands — separate visit records are created, so the total hours and number of trips reflect reality.

Spare parts, stock and procurement

Two things affect profitability most in field service: wasted trips and parts you do not have. Both come down to stock visibility.

Parts are tracked per stock location. The main warehouse and every service van can be defined separately, so you can see which part sits in which vehicle. Parts used on a work order are deducted from that location and the movement is recorded.

Suppliers and purchase orders are held in the system too. Which supplier a missing part was ordered from and when it is due can be seen from the work order, so the date you give the customer rests on a record rather than a guess.

• Stock locations per warehouse and van

• Automatic part deduction from work orders

• Visibility of critical stock levels

• Supplier and purchase order tracking

• Full stock movement history

Preparing quotes and getting approval

Work outside warranty starts with a quote built from labour and parts lines and sent to the customer with the total.

Not starting before approval prevents disputes over the amount afterwards and cuts the time a technician spends waiting on site. The approved quote is linked to the work order, so what was done can be compared against what was agreed.

Planned maintenance contracts

Planned maintenance and panel cleaning affect generation efficiency directly; neglected maintenance causes a measurable loss over a year of output.

A contract defines scope, interval (monthly, quarterly, half-yearly, annual) and the equipment covered. The system creates the work orders when each interval falls due — the possibility of forgetting a maintenance visit disappears.

A maintenance contract also means predictable revenue. Moving from turnover that swings with breakdowns to steady contract income is the single most decisive step in growing a field service business.

How customers follow their job

A significant share of calls to a service business are not new requests but "what is happening with my job?". Those calls tie up the office and leave the customer uncertain.

AsentTime generates a shareable tracking link for each work order. Customers see what stage their job is at themselves, with internal statuses simplified before they are shown — the detail of your operation stays inside.

You can also publish a fault reporting form. Requests submitted through it become work orders directly, removing the risk of details being lost in a phone call.
