Are Solar Panels Worth It?

Solar can be worthwhile when local electricity prices are high, roof conditions are suitable, installation costs are reasonable, and you can use a meaningful share of the electricity on site. It is not automatically the best choice for every household, especially where export credits are low or the roof is heavily shaded.

Start with the household need rather than the panel size. Review annual kWh, daytime use, future EV charging, electric heating plans, and how long you expect to remain in the property. A system designed around a realistic usage profile is easier to evaluate than one sized only to a marketing claim.

Roof condition, orientation, shading, structural constraints, and local connection rules affect production and installation cost. Ask for a proposal that clearly separates equipment, labor, electrical work, permitting, monitoring, warranties, and any optional battery. Comparing like-for-like proposals makes the trade-offs visible.

The best answer depends on your bill, roof, incentives, export rate, and how long you expect to stay in the home. Use a calculator to test modest changes to rate, self-consumption, and incentive assumptions rather than relying on a single optimistic payback figure.

Before signing, verify rebate eligibility and export arrangements with the relevant authority or utility. Read warranty terms and understand who will support the system if an installer changes ownership. A solar decision is stronger when the financial case still makes sense under conservative assumptions.

For a useful comparison, keep the period, units, and assumptions consistent across each option. Use a calculator to explore the figures, then rely on current documents from the relevant provider or authority for terms that apply to your home.
