Disconnecting solar panels safely requires understanding that solar panels generate electricity whenever they’re exposed to light — you cannot turn panels “off” the way you turn off a light switch. Even with all breakers open and the inverter disconnected, solar panel strings remain energized as long as sunlight is hitting them. Safe disconnection uses the Read more »
Solar panels come in a range of physical sizes and wattages depending on whether they’re built for a residential roof, a commercial rooftop, or portable use. Most residential panels today measure around 65×39 inches and produce 400-450 watts, while commercial panels are larger and portable panels are much smaller and lower-powered. Standard Residential Panel Dimensions Read more »
Whether solar installation voids your roof warranty depends heavily on your roof’s age, the manufacturer’s specific warranty terms, and how carefully the installer handles roof penetrations. Most roof warranties remain intact if installed properly on a roof within its expected service life, but some manufacturers have specific clauses homeowners should verify beforehand. Types of Roof Read more »
Solar battery storage lets you capture the excess electricity your solar panels produce during the day and use it after dark — or whenever the grid goes down. The result: lower electric bills, protection against peak-hour utility rates, and a reliable backup power source that keeps your lights and refrigerator running through outages. If you’re Read more »
Solar tracking systems move panels throughout the day to follow the sun’s position, capturing significantly more energy than a fixed installation — but they add mechanical complexity, cost, and maintenance requirements. Single-axis trackers boost output 25-35%, while dual-axis systems reach 30-45%, though both are primarily used in utility-scale rather than residential settings. Types of Solar Read more »
Not having a roof doesn’t have to mean missing out on solar savings. Renters and apartment dwellers can access solar benefits through community solar programs, portable balcony panels, or by advocating for landlord-installed systems. Community Solar Programs Available in 20+ states, community solar lets you subscribe to a share of a local solar farm’s output, Read more »
Solar thermal water heaters use the sun’s heat directly to warm water, rather than converting sunlight to electricity like PV panels. The two main designs — flat plate and evacuated tube collectors — differ in efficiency, cost, and climate suitability, and both can significantly cut water heating costs. How Solar Thermal Water Heating Works A Read more »
Gel batteries are a sealed lead-acid battery variant that once served as a reliable middle-ground choice for solar storage — less maintenance than flooded lead-acid, but at a lower cost than lithium. While lithium (LiFePO4) has become the standard for most new solar installations, gel batteries remain relevant for specific budget-conscious or replacement scenarios. Gel Read more »
Floating solar (floatovoltaics) installs panels on bodies of water instead of land or rooftops, offering unique advantages for utilities and large landowners. Floating solar arrays reduce water evaporation, avoid land-use conflicts, and benefit from cooler operating temperatures that boost efficiency. Floating Solar vs. Ground-Mount Solar Factor Floating Solar Ground-Mount Solar Land use None — uses Read more »
A solar cell is the fundamental building block of every solar panel — the small silicon wafer that actually converts sunlight into electricity. Understanding how individual cells work, and how they’re wired together, explains everything about how a full panel performs. What a Solar Cell Actually Is A solar cell is a thin wafer of Read more »
