When to use and what to include
Draft the system approach, timeline, and pricing online, then generate a proposal PDF for review. Use this after a roof assessment and energy-usage review when the customer needs the proposed design, production assumptions, utility and incentive inputs, installation scope, schedule, and price in one document.
What to include
- Property address, roof assessment summary (orientation, pitch, shading analysis with percentage of usable area), current annual electricity usage in kWh from utility bills, and average monthly electric bill.
- System design: total system size in kW DC, panel brand/model and wattage per panel (e.g., a 400-440W tier-one module), panel count, inverter type and model (string inverter, microinverter, or DC optimizer from brands like Enphase or SolarEdge), and expected annual production in kWh.
- Warranty summary using the current documents for the quoted equipment and installer: covered components, performance or degradation terms, period, start date, exclusions, claim process, transfer terms, and separate workmanship or roof-penetration coverage actually offered.
Common questions
- Can I structure this Solar Installers Proposal online for different client scenarios?
- Yes. Revise the proposed work, options, schedule, and pricing in the guided form before downloading the final PDF.
- Can I save this Solar Installers Proposal and reuse its structure for another customer?
- Yes. With an account, save it in your history, edit it later, and reuse its details as a starting point for another customer.
- Can I generate a presentation-ready PDF from this Solar Installers Proposal?
- Yes. Export a polished PDF suitable for email delivery, proposal reviews, and approvals.
- What size system do I need?
- System size is based on your annual kWh usage divided by your roof's production factor (based on orientation, pitch, and sun hours). A typical US home uses 10,000 kWh per year, which needs roughly a 7 to 9 kW system.
- What is the difference between string inverters and microinverters?
- String inverters are cheaper but the whole string drops output if one panel is shaded. Microinverters on each panel optimize independently and allow panel-level monitoring. Recommend microinverters for roofs with partial shading.
- How long does the installation process take?
- Record the estimated installation duration separately from permitting, inspection, and utility-interconnection milestones. Timing varies by system, site, authority, and utility, so confirm current dates with the responsible parties.
- Will solar panels damage my roof?
- The proposal should state the mounting and flashing method, roof-condition findings, who is responsible for roof work, and the exact penetration warranty offered. A qualified installer or roofer should assess roof suitability and applicable installation requirements for the site.
- What is the difference between a proposal and a quote?
- A quote presents the price for a defined job. A proposal also explains your approach, timeline, materials, and pricing, which suits larger or multi-phase projects.
- What makes a proposal clear and complete?
- Describe the project approach, deliverables, materials, timeline, pricing, assumptions, and next step in terms specific to the customer.
- Should I include multiple pricing options?
- Yes. Three clearly defined options let customers compare scope, equipment or materials, performance, and price before choosing.
