Your best shot at winning a sale is with a well-developed solar sales proposal. It shows legitimacy, demonstrates technical skill, and helps the home or business owner feel comfortable with a major investment. Even if you create your proposals with sophisticated solar proposal tools, you still need to know what to include.
In today’s competitive renewables landscape, particularly in markets with high levels of solar installation like California, a prospect needs more than a plain quote sheet. Instead, a well-crafted solar sales proposal can differentiate your company from competitors and help move the customer toward a decision. Here is what to include.
1. Executive Summary & Company Overview
Start your proposal with an executive summary that focuses on the customer’s needs and your solution. Then, provide a company profile that explains your licensing, experience, and coverage area.
For California customers, mention your solar installation license, such as C-46 or C-10. Customers want to know they are dealing with a legitimate contractor. This detail can build trust, especially in a market where customers may have concerns about unreliable solar companies.
In addition, working with solar proposal software can support your sales process. An association with a solar proposal company like PTO Edge can help your team present project information in a clear and professional format.
2. System Design & Site Assessment Details
System design and site assessment give the customer a clear picture of the proposed solar project. Therefore, your solar sales proposal should include:
- A roof or ground-mount design layout generated from solar design software
- The number, brand, and model of panels, along with their efficiency
- The inverter type, including string inverter, microinverter, or power optimizer
- Shade reports and estimated annual energy production in kWh
- Battery storage details, when included in the system
For example, solar software companies such as Aurora Solar, Solargraf, and OpenSolar can create 3D renderings and shade reports. These visuals make technical information easier for clients to understand.
| Pro Tip: Always include solar plan sets when appropriate, or state that you will provide them after the customer signs the contract. Engineered drawings can support the permitting process and show that your team has planned the project carefully. |
3. Energy Production & Savings Analysis
Numbers can help customers understand the financial value of solar. For this reason, your solar sales proposal should clearly present the expected savings and energy production.
Show the customer their current annual utility spending and compare it with the expected solar energy production. You can also include the estimated energy offset and projected savings over the system’s expected life.
- Current annual utility spend
- Anticipated solar energy production and energy offset
- Estimated long-term savings
- Estimated return on investment
- Net metering credits and applicable utility rates
Solar proposal software can calculate many of these estimates using customer utility information. For example, PTO Edge can use utility bill data or manual entries to support proposal calculations and reduce manual data-entry work.
4. Pricing, Financing & Incentives
Next, make your pricing easy to understand. Start with the total system cost and then show applicable incentives, rebates, and other financial considerations.
For eligible projects, explain the U.S. Federal Investment Tax Credit and any applicable state or local incentives. California customers may also want information about utility programs, net metering rules, and battery incentives that apply to their project.
Also, provide suitable financing options. Depending on your business model, these may include cash purchases, solar loans, power purchase agreements, or leases. Good solar proposal software can help sales teams compare payment options during a customer presentation.
5. Timeline, Warranty & Next Steps
Finally, explain what happens after the customer approves the proposal. Provide a clear project timeline from contract signing through installation and Permission to Operate (PTO).
If you use PTOEdge to manage the utility interconnection process, explain how the platform supports the post-sale workflow. Clear status updates can help your team keep customers informed while the utility processes the interconnection application.
Also include:
- Panel and equipment warranty information
- Inverter warranty information
- Labor warranty details
- Production guarantee details, if offered
- A clear call to action and e-signature option
| Pro Tip: The most effective solar sales proposal combines clear project information, accurate financial details, professional visuals, and a simple path to the next step. |
FAQs about Solar Sales Proposal
What is a solar sales proposal, and why does it matter?
A solar sales proposal is a tailored document that explains a proposed solar project to a potential customer. It usually covers system design, expected energy production, project cost, applicable incentives, financing options, and the installation timeline. A clear proposal helps customers understand the project and the next steps before they make a decision.
What should a solar sales proposal include?
A solar sales proposal should include company information, system design details, estimated energy production, savings information, pricing, financing options, applicable incentives, warranties, project timelines, and next steps. Depending on the project, it can also reference solar plan sets and the utility interconnection process.
Do I need a solar installation license to sell solar in California?
California requires solar installation contractors to hold the appropriate contractor license for the work they perform. C-46 covers solar contractor work, while C-10 covers electrical contractor work. The California Contractors State License Board (CSLB) provides the applicable licensing requirements and rules for contractors operating in California.
What are solar plan sets and should I include them in my proposal?
Solar plan sets are detailed project drawings that can support the permitting and installation process. They may include site layouts, electrical diagrams, roof layouts, equipment details, and structural information. A sales proposal does not always need to contain the complete plan set, but it can explain when the drawings will be prepared and submitted for permitting.
How does PTOEdge help solar companies manage the post-sale process?
PTOEdge supports the utility interconnection workflow for solar companies. The platform can help teams manage application information, monitor project status, review documents, and keep customers informed during the interconnection process. This can create a clearer workflow from contract signing to Permission to Operate (PTO).
