How to choose a home solar system

Panels generate electricity; the inverter makes it usable

Panels generate direct current, which an inverter converts to alternating current for household appliances. kWp describes rated panel power; kWh measures energy used for billing. Actual output depends on sunlight, temperature, shade, orientation and system losses.

Choose a system for the job you need

On-grid connects to the utility to reduce purchased electricity. Hybrid equipment can manage batteries depending on the model. Off-grid requires enough energy and backup without utility support.

• To reduce bills: check loads that coincide with sunlight.
• For backup: specifically verify supported backup circuits and power ratings.
• To export electricity: eligibility and a separate contract are required.

Prepare this information before requesting a quote

Collect 12 months of kWh usage and bills. Photograph the meter and distribution board from a safe location. Describe when you are home, plans for an EV or extra air conditioning, and roof-repair history. Have the installer survey the site before confirming the design.
