Practical preparation guides for homeowners who want answers before the first installer visit
Most solar conversations start with equipment. Ours start with what your house already tells you: how much power you use, where shade falls at midday, and whether your roof and electrical service can support a safe installation. We walk through those steps so you know what to ask — not what to buy.

Pull twelve months of utility records before anyone mentions panel count. Seasonal spikes from heating, pool pumps, or an EV charger change the conversation entirely. Knowing your baseline kWh helps you spot when a proposal assumes usage you do not actually have.
A clear morning does not guarantee a clear afternoon. Walk outside at three set times and note where shadows cross your best roof sections. Chimneys, vent stacks, and neighbor trees move differently than satellite images suggest.
South-facing slopes are a starting point, not a verdict. East and west arrays can work when afternoon usage is high. Steep pitches affect mounting hardware and walkway clearance — details that belong in your notes before the ladder goes up.
Your main panel rating, available breaker spaces, and meter configuration determine whether a system connects cleanly or needs upgrades. Photograph the label on your electrical panel and note whether your service is overhead or underground before scheduling site visits.
Most counties require building permits and an electrical inspection before a grid-tied system goes live. Ask your local office which documents they expect — site plans, structural letters, interconnection forms — so nothing stalls after panels arrive on the truck.
A licensed installation crew handles roof penetrations, conduit runs, and final commissioning. That is different from a handyman who offers to mount panels without pulling permits. Know the distinction before you sign anything.
Work inside your main panel, service disconnects, and grounding systems belongs to a licensed electrician. We explain what questions to ask; we do not walk you through live wiring.

Step-by-step notes from our latest homeowner reviews
Most homeowners skip straight to panel wattage. Your bill already shows seasonal swings, baseline loads, and the months where air conditioning dominates — clues that change how many modules actually make sense.

Drone surveys look impressive, but they often miss the hour when production peaks. Standing in your yard at noon reveals whether a branch, dormer, or neighbor roofline cuts into the space you assumed was open.

Tell us about your roof, shade, and utility records. We help you organize the questions worth asking before any installer visit — no equipment sales, no installation booking.
The materials on this site provide knowledge about residential solar preparation — roof assessment, shade observation, utility review, and permit planning. They are intended to help you understand the steps involved before contacting licensed professionals.
RoofMeter Guide is not a solar installation company. We do not visit homes to mount panels, schedule installations, or provide project quotes. We are also not a retail store: we do not sell panels, inverters, batteries, or compare equipment brands and models.
We do not promise payback timelines, specific savings figures, zero utility bills, or free electricity. Tax credits, utility rates, and interconnection rules change by state and provider — consult official government and utility sources for current information.
Grid interconnection, work inside your electrical panel, and structural roof assessments require licensed electricians, engineers, and local authorities. Do not attempt these tasks yourself based on website content.
Every home differs in roof condition, shading, consumption, and budget. A plan that worked for a neighbor may not fit your property. Any decisions about system size, equipment, or contractors are yours alone.
