A useful solar proposal connects energy use, roof suitability, and the full installation cost. Every part should make sense together.
Bring recent bills. Discuss seasonal use, an electric vehicle, a planned ADU, or other changes before choosing a system size.
Review roof age, condition, orientation, shading, available area, and access. Coordinate roofing needs before installing panels.
Review equipment, installation, electrical work, permits, utility approvals, warranty documents, and the assumptions behind production estimates.
A useful solar design brings the roof, household usage, equipment, and future plans into the same conversation. Look at the whole system before focusing on a headline number.

Discuss roof condition, available area, shade, orientation, and equipment placement.

Review equipment specifications, mounting, electrical work, and written warranty documents.

If your roof needs attention, address it in the project plan before panel placement. Avoid treating roof condition and system design as separate conversations.
Ask for a written system proposal that explains the equipment, work, costs, and requirements for operation.
Discuss recent utility statements, household consumption, and changes expected from new appliances, an EV, or an ADU.
Review roof condition, available area, shading, orientation, mounting considerations, and any planned roof work.
Discuss capacity, equipment layout, electrical requirements, and the assumptions behind production estimates.
Review panels, associated equipment, mounting, electrical work, permits, and the responsibilities included in the proposal.
Identify the applicable utility process and approvals needed before the system is allowed to operate.
Compare total installed cost, exclusions, equipment documents, production assumptions, and financing terms if considered.
Production estimates are not guaranteed bill savings. Usage, shade, utility rates, fixed charges, and export rules affect the result.
Compare a solar installation budget with an annual energy-production scenario. Adjust the capacity, installed rate, and production assumptions.
A final proposal starts with your address and a defined scope. Default solar rates are illustrative and adjustable.
Explore system cost and annual production using editable example assumptions.
Example inputs, not Wilshire pricing, guaranteed generation, or bill savings. Production divided by annual use is an energy comparison, not a utility-bill offset. This total does not apply tax credits, rebates, financing, or utility export payments.
Book a free in-home consultation. Have recent utility bills and details about your roof and future electricity needs ready.
Discuss site conditions, shade, roof suitability, equipment placement, and the electrical work involved.
Review capacity, installed scope, production assumptions, total cost, warranty documents, and required approvals.
Follow the agreed installation sequence, inspections, and utility requirements before operation.
Start with your home and your actual electricity use. Ask about the details behind the system proposal.
Yes. Book a free in-home estimate and consultation with no obligation to hire. Discuss your roof, electricity use, and what needs to be reviewed for a project-specific proposal.
Not necessarily. Usage, system production, utility rates, fixed charges, and export rules affect bills. Production as a percentage of annual use is not the same as a bill reduction.
System sizing depends on actual and expected consumption, usable roof area, shade, orientation, electrical conditions, and utility requirements. Bring recent bills to the consultation.
Review roof condition and remaining service life before choosing panel locations. If roofing work is needed, coordinate the two scopes and sequence before installing the system.
No. The calculator does not apply tax credits, rebates, financing, or utility export payments. Confirm any current incentive eligibility independently before relying on it.
Discuss equipment, complete installed cost, production assumptions, warranties, exclusions, financing terms, and utility steps. Review the current CPUC Solar Consumer Protection Guide before signing.
