Yes — solar panels and the metal components of every solar installation must be grounded, and this requirement is not optional or cosmetic. Grounding protects people from electric shock if a fault develops, protects the equipment from lightning-induced voltage spikes, and is required by the National Electrical Code (NEC) for every residential and commercial solar Read more »
Your solar monitoring app provides real-time and historical data on what your system is producing — but knowing how to interpret the numbers transforms monitoring from a passive dashboard into an active tool for catching problems and maximizing your system’s value. The three most important numbers to check are today’s production, lifetime production to date, Read more »
A common misconception is that solar panels don’t work well in winter. In reality, solar panels often perform better in cold weather than in summer heat — cold temperatures improve panel efficiency, and reflective snow on the ground can actually boost production. What reduces winter output is shorter days and lower sun angles, not temperature. Read more »
Solar panels installed correctly by a licensed contractor do not damage roofs — in fact, they can extend roof life by shielding shingles from UV radiation and weather. The vast majority of solar roof damage claims stem from improper installation: incorrect flashing, inadequate sealant, penetrations into cracked or near-end-of-life shingles, or installers who don’t understand Read more »
A solar carport combines covered parking with solar power generation — panels are mounted on a structure over your driveway or parking area rather than on your roof. Solar carports cost $15,000–$50,000+ for residential installations and are increasingly popular for homeowners whose roof is unsuitable for solar (wrong orientation, too shaded, near end of life) Read more »
Virtual net metering (VNM) allows electricity customers to receive credits on their utility bills for solar energy generated at a location other than their home or business — typically a shared community solar installation. Unlike traditional net metering, where your rooftop panels offset your own meter’s consumption directly, virtual net metering routes solar production credits Read more »
Solar rebates reduce the upfront cost of installation through direct payments from utilities, state programs, or manufacturers. Unlike tax credits (which reduce what you owe in taxes), rebates are typically direct cash reductions applied at the time of purchase or paid out after installation. Rebates can range from a few hundred dollars to $15,000+ for Read more »
Solar energy can dramatically reduce electricity costs for small businesses — often more favorably than for residential homeowners, thanks to commercial tax incentives, accelerated depreciation, and the ability to reduce demand charges. A properly sized commercial solar system can cut a small business’s electricity bill by 50–90% and pay for itself in 5–10 years, then Read more »
The best states for solar combine high electricity rates, strong net metering policies, state-level incentives, and adequate sunshine — and these factors matter more than peak sun hours alone. Massachusetts, New York, and New Jersey often deliver better solar economics than sunnier states like Arizona or Nevada because high electricity rates make every kWh of Read more »
Solar panels require periodic cleaning to maintain peak production — dirt, bird droppings, pollen, and dust reduce output by accumulating on panel surfaces. Professional solar panel cleaning typically costs $100–$400 per visit for a residential system, while DIY cleaning costs almost nothing with the right approach. This guide covers when panels need cleaning, what professional Read more »
