Solar Panel Installation Model
Build a 10-year forecast for a Solar-as-a-Service business that installs panels without charging an upfront installation fee, then earns recurring revenue from customer electricity usage and excess power sold to the grid. Model deployment timing, energy production, financing, direct costs, valuation, and returns across a scalable portfolio.

What the model includes
A scalable 10-year model for recurring solar-energy revenue.
Build the portfolio one deployment tranche at a time, then roll the activity into operating results, debt coverage, valuation, and equity-return outputs.
Model a large deployment pipeline
Enter up to 200 separate installation tranches, each with its own timing, cost, financing, production, pricing, and direct-cost assumptions.
Follow the operation from launch through maturity
Forecast up to ten years with the monthly detail needed for rollout timing and annual views for planning and presentation.
Calculate customer payments from kWh usage
Forecast recurring revenue from energy consumed by each customer instead of relying on a one-time panel installation fee.
Monetize excess power production
Separate energy used by the customer from excess production sold to the grid using its own kWh price assumptions.
Shape annual output across the calendar
Allocate expected annual power production by month to reflect the seasonal pattern of solar generation.
Model financing as the portfolio scales
Define financing percentage, interest rate, and term by tranche, then monitor debt-service coverage as deployments grow.
Evaluate IRR, DCF value, and equity multiple
Measure investment returns, apply an EBITDA exit multiple, and review the value created for equity investors.
Use 18 charts and two scenario tables
Review 18 visualizations plus IRR and NPV sensitivities across changing exit years, EBITDA multiples, and discount rates.
The business behind the model
Install the system now and earn from the energy over time.
The operating concept differs from a traditional installer that earns a one-time project fee. The model follows the economics of retaining the installed system and monetizing its production.
No upfront installation charge
The customer receives the solar installation without paying a conventional installation fee at deployment.
Customer energy revenue
The business earns recurring revenue as the customer pays for electricity consumed, measured in kWh.
Excess-power sales
Power produced but not used by the customer can be sold to the grid under a separate pricing assumption.
Deployment-level economics
Every tranche carries its own installation timing, cost, financing, production, pricing, and ongoing direct costs.
Scalable rows
A row can represent one installation or a group of 10, 20, 100, or more installations by scaling the cost, production, and direct-cost assumptions.
Long-term drivers
Define how customer kWh pricing, grid pricing, and direct costs change over time across the operating forecast.
Inputs for every deployment tranche
Build the portfolio with bottom-up installation assumptions.
Each tranche can reflect a different launch schedule, financing package, energy profile, selling price, and cost structure.
Installation and revenue start dates
Define the installation month, the lead time from installation to kWh production, and the month recurring revenue begins.
Installation cost and financing terms
Enter the total installation cost, percentage financed, interest rate, and loan term for each deployment tranche.
Usage, price per kWh, and price cap
Forecast annual MWh consumed by the customer, the contracted kWh price, and any cap applied to that pricing.
Excess power and ongoing obligations
Model the energy sold to the grid, grid price per kWh, maintenance, insurance, and other recurring direct costs per installation.
Decision-ready outputs
Follow operations, financing, value, and returns in one model.
The deployment assumptions flow into a detailed operating forecast and a focused set of executive and investor outputs.
Monthly and annual pro forma
Review detailed revenue, direct costs, EBITDA, cash flow, and operating performance at both monthly and annual levels.
Annual executive summary
Use a higher-level annual view to communicate the scale, financial trajectory, and key results of the business.
IRR, DCF, and equity multiple
Evaluate investor returns and present value using the forecast cash flows, discounting assumptions, and exit economics.
Exit value and DSCR
Apply an EBITDA exit multiple and monitor debt-service coverage, an important constraint when debt is used to accelerate deployment.
Two sensitivity tables
Test IRR across exit year and EBITDA multiple, then test NPV across discount rate and EBITDA multiple.
How to use it
Move from deployment assumptions to portfolio returns.
Build the deployment schedule
Enter the installation month, cost, production lead time, and revenue start for every planned tranche.
Define energy and pricing economics
Set annual customer usage, customer and grid kWh pricing, price caps, seasonality, and long-term pricing drivers.
Add financing and ongoing costs
Enter the financed percentage, rate, term, maintenance, insurance, and other direct costs associated with each tranche.
Review cash flow, coverage, value, and returns
Use the pro forma, summary, DSCR, DCF, IRR, equity multiple, charts, and sensitivity tables to test the plan.

A few useful details.
How does this business make money?
The modeled business installs panels without charging an upfront installation fee, then earns recurring revenue from customer kWh usage and excess power sold to the grid.
How many deployments can the model handle?
The template supports up to 200 deployment tranches. Each row can also represent a group of installations, allowing the model to scale to potentially thousands of systems.
What can be changed for each tranche?
Inputs include installation timing and cost, production lead time, revenue start, financing percentage, interest rate, term, customer and grid pricing, energy usage, grid sales, and ongoing direct costs.
How are financing and debt coverage handled?
Financing inputs are set by tranche, and the model calculates debt-service coverage because debt capacity is an important driver of deployment scale.
Which sensitivities are included?
One table sensitizes IRR across exit year and EBITDA multiple. The second sensitizes NPV across discount rate and EBITDA multiple.
Is it included in any bundles?
Yes. It is included in the Industry-Specific, Renewable Energy, and Super Smart bundles.
