Most installers live on a roller coaster: sell, install, get paid once and move on to the next. O&M (operation and maintenance) breaks this cycle: it turns each installed system into recurring revenue, retains the customer and generates referrals. It is the difference between running a business and running a series of jobs.
Why O&M is the installer's best asset
Each installed customer is a system that will run for 25 years and will need attention: cleaning, inspection, the occasional component replacement. If you do not offer that service, someone else will — or the customer will go to a competitor when something fails. O&M is predictable revenue, good margin and the best bridge to upselling (expansion, batteries) and referrals.
What to include in the plan
A solid O&M plan combines remote monitoring of generation (with alerts), periodic inspections (visual and thermographic), module cleaning, checks of connections and protections, a performance report and a service-level agreement (time to fix faults). Offer it in tiers (basic, intermediate, premium) to suit different budgets and system sizes.
How to price and sell recurring service
Common models: a monthly fee (subscription), an annual contract or a price per kWp per year (widely used for larger plants). Anchor the price on the value of protected generation: "monitoring prevents a problem from going unnoticed for months, which would cost far more than the fee". Include the plan in the sales proposal — it is easier to sign it with the installation than later.
