Solar-as-a-Service Startup Operating Model
This template is for a business that installs solar panels for free and then charges the customer for energy over time through power purchase agreements.

Description
Plan out all sorts of various financial scenarios and test feasibility based on various installation costs, pricing, and expenses over a 10-year period. There are 200 tranches that can be configured, each with their own inputs for the usage of debt as well as relevant revenue and expense drivers. I group them into rows of 10, where you can adjust each set of 10 deployments by adjusting the first row of the set.
I've included monthly and annual pro forma details that drive down to EBITDA and cash flow. There is also a DCF Analysis and return summary with IRR, total ROI, NPV, and Equity Multiple. The model assumes the minimum cash needed to keep the balance above zero is the initial investment. You can use the data on the DCF Analysis to plug into any sort of annual waterfall if this is a joint venture. It has a clear flow of the initial investment and cash flow produced over time.
The user can think of each row as an individual installation or as a group of installations. Simply adjust the expected initial cost, MWh production, and ongoing direct expenses accordingly.
The way this model is set up makes it easy to account for residential and/or commercial deployments.
The unit economics of installing solar panels for free and charging for the energy usage over time involves analyzing the costs and revenues associated with the business model to determine its financial viability and profitability. This model is often referred to as a "Solar-as-a-Service" or "Power Purchase Agreement (PPA)" model. Here's a breakdown of the key components:

This model is often referred to as a "Solar-as-a-Service" or "Power Purchase Agreement (PPA)" model. Here's a breakdown of the key components:
Costs
Installation Costs:
- Solar Panels: The cost of purchasing the solar panels themselves.
- Inverters and Other Hardware: Necessary equipment to convert and manage the solar power.
- Labor: Costs associated with installing the panels, including technicians and engineers.
- Permitting and Inspection: Fees paid to local authorities for permits and inspections.
- Routine Maintenance: Regular maintenance to ensure optimal performance, including cleaning and minor repairs.
- Monitoring: Costs associated with monitoring the system’s performance, often through software and remote management systems.
- Repairs and Replacements: Costs for any unexpected repairs or replacement of parts over time.
- Interest Payments: If the installation is financed through loans, the interest payments must be accounted for.
- Marketing and Sales: Expenses related to acquiring new customers, including advertising, sales commissions, and promotional activities.
Revenues
Energy Usage Fees:
- Electricity Sales: Revenue generated from charging customers for the electricity produced by the solar panels. This is usually at a rate lower than traditional utility rates, providing savings to customers.
- Billing Model: Can be structured as a fixed monthly fee, a variable rate based on usage, or a hybrid model.
- Excess energy the customers doesn't use can be sold to the grid, usually at a lower price.
- Government Incentives: Many governments offer incentives, tax credits, or rebates for renewable energy projects, which can enhance revenue or reduce initial costs.
- PPA Contracts: Long-term agreements (often 15-25 years) ensure a steady stream of revenue. The terms of the contract typically include escalators that increase the price slightly over time to account for inflation and increased energy costs.
