Solar sales is part teacher, part estimator, part trusted advisor. You help a homeowner or business understand their electric bill, size a system to fit it, and decide if the savings make sense. You do not need an engineering degree; about two thirds of people in this job have a 2-year degree or a bachelor's. What you need is solid basic math, clear explanations, and honesty. This roadmap starts with how electricity and solar work, then builds to reading bills and sizing systems, then to running a sale from lead to signed contract, and finally to commercial deals, financing structure and leade

Stage 1 of 3 · about 6 weeks
Understand how solar works and read a utility bill well enough to explain it to a neighbor.
Solar and electricity basics
Customers ask 'how does this actually work?' within the first five minutes. If you can explain kW versus kWh, panels, inverters and net metering in plain words, you earn trust. If you bluff, you lose the sale.
Reading a utility bill
The bill is your sales tool. It shows kWh used, rate per kWh, tiers or time-of-use rates and fixed charges. Sizing and savings all start here.
Spreadsheet math for sales
Most of your numbers are simple: percentages, averages, payback and savings over time. Excel or Google Sheets lets you do them fast and avoid mistakes in front of a customer.
Incentives and policy basics
The federal tax credit, state rebates and net metering rules change the price a customer sees. Misstating them is the fastest way to lose credibility or break the law.
