Is the roof suitable for solar panels?
Roof condition, usable space and sun exposure affect the installation. Have the installer review shading and any roof work expected before the panels go on. The proposal should show the array layout and explain the assumptions behind its estimated production. If reroofing is already planned, coordinate that work with the solar installation. Equipment can be priced more usefully when the proposal describes the roof and installation you actually expect to have, rather than only a panel count.
How should the solar system be sized?
Annual electricity use gives the installer a starting point. Share recent usage records and changes you expect, such as an EV charger or electric heating. Compare estimated annual production with the home’s expected consumption. Keep the production assumptions visible, including shading and the available roof area. The system size should be discussed with the household’s energy goals and budget; future additions should be identified rather than silently included in an estimate of today’s use.
What electrical and utility work is included?
The installation scope should identify panels, inverter equipment, wiring and any required panel changes. Include permits, inspection and utility interconnection responsibilities. For a grid-connected installation, confirm who handles the application and completion steps, and how utility requirements affect the sequence. If the electrical panel will be replaced in the same project, coordinate the connection design with that work. This helps the proposal describe one completed installation instead of leaving the connection to be priced later.
How much does solar panel installation cost?
System size, roof preparation, equipment and electrical changes affect the price. Compare the total installed scope and the estimated annual production using the assumptions provided for your property. Battery storage should be itemized separately, with its intended functions described. Keep financing terms separate from the equipment and installation price if financing is offered. An estimate should make clear which work is included, which is assigned elsewhere and what must be completed before the system can be connected.
Will solar provide power during an outage?
A standard grid-connected solar installation does not provide backup power during an outage. Backup requires compatible storage and equipment designed to isolate from the grid and supply the selected loads. If outage power is one of your goals, specify the circuits and equipment you want supported and have those functions included in the design. Request a solar estimate with annual usage records, the roof work you anticipate and any planned electrical additions.
