How the process works
It starts with a conversation about your power use and what you want the system to accomplish. A site review looks at the roof, shading, electrical panel, and meter before the design is finalized.
The written proposal shows the panel layout, system size, equipment, estimated annual production, consumption offset, price, assumptions, and warranty terms. If you proceed, East Coast Sun coordinates the utility application, permitting, installation, inspection, connection, and monitoring setup.
The equipment
Equipment is selected for the property rather than forced into one standard package. A published East Coast Sun sample proposal used 18 LONGi 500 W panels for a 9 kW array with a 10 kW Solis single-phase grid-tied inverter. Your proposal will identify the exact current models selected for your home.
The inverter turns the DC power from your panels into the AC power your home uses. Roof layout, shade, monitoring needs, service equipment, and budget all affect the right inverter and racking choice.
Warranties
The same published example included a 12-year panel product warranty, a 25-year panel performance warranty, and a 10-year inverter product warranty. Equipment changes over time, so the terms in your own written proposal are the ones that apply.

The East Coast Sun sample proposal shows the level of detail you can expect, including layout, production, financial assumptions, equipment, warranties, and next steps. Its old pricing and program information are examples only and should not be treated as a current quote.
Net metering matters for sizing
Utility rules affect the value of exported energy and the right system size. The net-metering guide explains the current and proposed rules, with proposed items clearly labelled.
