Installation of solar panels (priority n°1)

How it's done

• Diagnosis of the condition of the roof (watertightness, covering, framework, anchor points).
• Arbitration between local repair and complete refurbishment depending on the remaining lifespan.
• Roof + solar coordination on the same site to pool scaffolding and logistics.
• Integration of fixings and technical passages with waterproofing treatment.

Checkpoints

• Check in black and white which guarantees watertightness after intervention.
• Avoid installing PV on a roof that will need to be redone in the short term.
• Confirm allowable loads and anchoring zones before ordering material.

How it's done

• Implement production monitoring to detect abnormal deviation.
• Carry out a periodic visual inspection (dirt, debris, connectors, fixings).
• Plan cleaning only if necessary (heavy pollen, droppings, dust, low slope).
• Use gentle methods compatible with modules (clean water, soft brush, without abrasives).

Checkpoints

• Avoid risky interventions on roofs without suitable equipment/know-how.
• Request a clear cleaning protocol so as not to damage glass, seals and frames.
• Compare before/after on monitoring to validate the real effect of maintenance.

How it's done

• Analyze the actual load curve of the home (day, evening, peaks).
• Define the main objective: self-consumption, relief, or price arbitrage.
• Size the battery and check inverter/EMS/protection compatibility.
• Configure the charge-discharge strategy and validate the parameters during commissioning.

Checkpoints

• Do not choose battery capacity without actual consumption data.
• Check the useful capacity, the cycles/years warranty and the power limits.
• Request a compared economic scenario: with battery vs without battery.

How it's done

• Configuration of production alerts and remote monitoring.
• Periodic checks (performance, electrical safety, exposed components).
• Targeted diagnosis then replacement of faulty parts (inverter, protections, connections).
• Intervention report with corrective actions and post-repair monitoring.

Checkpoints

• Require a contractual response time in the event of a blocking failure.
• Plan who manages the manufacturer's warranty and associated labor.
• Maintain production history and reports for long-term monitoring.

How it's done

• Choice of a communicating terminal compatible with the inverter/EMS.
• Configuration of charging modes (single surplus, mixed, time schedule).
• Commissioning with dynamic tests when solar production varies.
• Adjustment of driving rules according to your mobility habits.

Checkpoints

• Check terminal + inverter compatibility before purchase.
• Ensure that the minimum charging power follows production variations.
• Measure the share of charging actually covered by solar after 1-2 months.
