What goes into a solar installation quote?
We explain the items to compare, from the panels to the access equipment. The lowest headline price may cover a different job.
Start with the same specification
Compare the panel model and quantity, inverter, mounting system and any battery. Ten 440-watt panels have a rated capacity of 4.4 kW. A quote for that system is not directly comparable with one using fewer panels or different equipment.
Look beyond the equipment
Access equipment, cable routes, electrical work and roof condition can affect the job. We discuss these before agreeing the scope. Ask which items are included, which are allowances and which are excluded.
Keep optional items separate
A battery, backup capability or an EV charger can change the total. Ask for each addition to be identified so you can decide what to do now and what to consider later.
Read the handover details
Ask what testing, documents, warranty cover and support are included. We do not publish a universal installed price because the scope has to be established for your property.
