Assess Your Site and Choose the Right Kit

Start by measuring roof orientation, tilt, and shading. South‑facing roofs with a 30‑45° pitch capture the most sunlight in the northern hemisphere. Use IKEA's online solar calculator or a free solar‑irradiance map to estimate annual kWh production for the selected panel model. Choose a kit that matches your energy needs and roof size; IKEA offers 1‑panel, 2‑panel, and 4‑panel packages ranging from 300 W to 1.2 kW each.

Gather Permits and Verify Electrical Compatibility

Before any mounting, check local building codes and utility interconnection requirements. Most jurisdictions require a building permit for structural changes and an electrical permit for grid‑tie inverters. Submit IKEA's pre‑filled permit packet, which includes system diagrams and voltage specifications, to your municipality. Confirm that your home's main breaker panel can accommodate the additional circuit; a 20 A or 30 A breaker is typical for a single‑panel kit.

Mount the Panels Securely

Install the mounting rails on rafters using the supplied stainless‑steel brackets. Space the brackets 1 m apart to distribute load evenly and follow IKEA's torque settings (8‑10 Nm). Attach the panels to the rails with the provided clamps, ensuring a 5‑mm gap between panels for thermal expansion. For flat roofs, use the low‑profile tilt kit that angles panels 15‑20° to improve runoff and efficiency.

Wire the System According to the Diagram

Run DC cabling from each panel to the junction box, using MC4 connectors rated for outdoor use. Connect the positive leads together, then the negative leads, forming a series string if you need higher voltage, or a parallel string for higher current. Feed the combined DC output into the inverter's MPPT input, observing polarity markings. Secure all connections with weather‑proof tape and route cables through conduit to protect against UV and mechanical damage.

Commissioning, Testing, and Grid Connection

After wiring, install the inverter on a ventilated wall mount near your main service panel. Connect the inverter AC output to a dedicated circuit breaker, then label the breaker as "Solar PV". Power on the inverter and use the built‑in diagnostic screen to verify voltage, current, and power readings match the expected values from your panel rating. Submit the final inspection report to the utility; they will perform a net‑metering test before approving export of excess electricity.

Maintenance and Performance Monitoring

Inspect the panels twice a year for dust, bird droppings, or loose clamps. Clean with a soft brush and water; avoid abrasive detergents that could scratch the anti‑reflective coating. Monitor output through IKEA's Solar App, which logs daily production and alerts you to any fault conditions. Replace a faulty panel or inverter under IKEA's 25‑year product warranty and 10‑year performance guarantee.
