Solar 101: How residential PV works, who it helps and how to avoid common scams
Summary
Solar United Neighbors presented a Solar 101 covering PV basics, siting criteria, costs and financing; presenters urged homeowners to check warranties, get multiple bids and use vendor-neutral help desks to avoid scams.
Monica Kerry, Pennsylvania program director for Solar United Neighbors, opened the webinar with a plain-language primer on residential solar systems and consumer protections. "Today I'm going to give a solar 101," Kerry said, and walked attendees through the basic technology and buyer safeguards.
Kerry explained that "solar" in the presentation referred to photovoltaics (PV), which convert sunlight to electricity; an inverter turns that DC output into the AC used in homes and provides monitoring capability. She recommended measuring system size in kilowatts (kW) rather than panel count and distinguished that a kilowatt-hour (kWh) is the unit homeowners see on bills.
Why some roofs work and others do not: Kerry listed four practical siting criteria homeowners should check before getting proposals — roof orientation (southerly preferred, easttowest acceptable), shading, at least about 250 contiguous square feet for a modest rooftop array, and a roof in good condition (she recommended installing on roofs no older than about 10 years).
On costs, Kerry said a 10 kW residential system in Pennsylvania currently costs about $30,000 on average and that payback periods in the state typically fall in the 8-to-12-year range. She illustrated how net metering lets owners bank kilowatt-hours month-to-month and noted the billing year runs June 1 to May 31.
Kerry emphasized consumer protection steps: get multiple bids, compare the specific panels, inverters and racking listed in proposals, check reviews on EnergySage and Solar Reviews and ask for references. She also recommended Solar United Neighbors' free help desk for unbiased proposal review. "We have experts who are going to offer you unbiased opinions on your proposals," she said.
Kerry warned homeowners to watch for high-pressure sales tactics, exaggerated savings claims and misstatements about incentives. "The solar tax credit is gone," she said about residential eligibility, adding limited exceptions may still exist for some nonprofits and commercial systems.
The session closed with practical financing advice: paying cash yields the most lifetime savings, but loans (including HELOCs or installer financing) and some credit-union products are common. Kerry cautioned owners considering third-party ownership (leases or power purchase agreements) that those arrangements often reduce direct homeowner benefit and historically have been a frequent vector for consumer complaints.
Next steps: attendees were urged to gather multiple proposals, confirm installer warranties and engage vendor-neutral resources if uncertain. Solar United Neighbors and local programs listed contact information for follow-up resources and help-desk support.
