When to use this template

Draft your approach, timeline, and pricing online, then generate a proposal PDF you can send immediately. Use this after completing a roof assessment and energy usage review when a homeowner or business wants a comprehensive plan for going solar, including system design, financial analysis, and timeline.

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.
  • Financial analysis: total system cost before incentives, federal Investment Tax Credit (ITC) amount at current percentage, state and local rebates, net cost after incentives, estimated monthly loan payment if financed, payback period in years, and 25-year savings projection.
  • Installation plan: permit timeline, HOA approval steps if needed, installation duration in days, electrical panel upgrade if required (100A to 200A), utility interconnection application, and net metering enrollment.
  • Warranty summary: panel performance warranty (25 to 30 years with degradation rate), inverter warranty (12 to 25 years), workmanship warranty from installer, and roof penetration leak warranty.

Common questions

Can I structure this Solar Installers Proposal online for different client scenarios?
Yes. Edit scope options, sequencing, and pricing narrative in-browser before exporting a final version.
Can I save this Solar Installers Proposal and repurpose it for new prospects?
Yes. With an account, save and duplicate it so you can reuse proven structure while tailoring project specifics.
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?
Installation itself is one to three days. But permits, utility interconnection approval, and inspections add four to twelve weeks total from signed contract to powered-on system.
Will solar panels damage my roof?
Properly installed mounts use lag bolts with flashing that seals the penetration. A good installer includes a 10-year roof penetration warranty. If your roof needs replacement within 5 years, do that first.
What is the difference between a proposal and a quote?
A quote gives a price. A proposal presents your plan — approach, timeline, materials, and pricing — to persuade the customer. Use proposals for larger or competitive jobs where you need to sell your approach, not just your price.
How do I make my proposal stand out from competitors?
Focus on specifics: describe your approach to their project, include a timeline, and address their concerns directly. Generic proposals lose to detailed ones even if the price is lower.
Should I include multiple pricing options?
Yes. Offering good, better, and best options lets the customer choose rather than just say yes or no. Most will pick the middle option, which often means a higher ticket for you.
