Understanding battery storage capacity helps homeowners size a system that meets their backup goals without overpaying for unused capacity. Usable capacity (kWh), not total capacity, determines how much power you can actually draw before recharging. Battery Capacity Terms Explained Term What It Means Total capacity (kWh) The battery’s full rated energy storage Usable capacity (kWh) Read more »
Solar panels power far more than just homes — their applications span residential, commercial, utility, transportation, and even space technology. From rooftop homes to satellites orbiting Earth, solar panels generate power across nearly every scale of human activity. Solar Panel Applications by Scale Application Example Residential Rooftop home systems, off-grid cabins Commercial Business rooftops, parking Read more »
A home equity line of credit (HELOC) is one of several ways to finance solar panels, offering potentially lower interest rates than dedicated solar loans in exchange for using your home as collateral. HELOCs often offer lower rates than solar-specific loans, but carry the risk of using your home as collateral and typically have variable Read more »
Solar skins are a niche aesthetic product that applies a printed layer over standard solar panels, letting them blend with roof color or display custom designs. Solar skins like Sistine Solar’s product sacrifice some efficiency for aesthetics, at a meaningful cost premium over standard black panels. Solar Skins Overview Factor Solar Skins Standard All-Black Panels Read more »
The Sun Number Score was once a popular tool for quickly estimating a home’s solar potential, though its availability and role have shifted in recent years. Sun Number scoring assessed roof orientation, shading, and size on a 0-100 scale, but Zillow discontinued its integration, shifting homeowners toward alternative tools. Sun Number Score Basics Score Range Read more »
Air conditioning is one of the biggest electricity draws in most homes, making it a prime target for solar offset — though “solar air conditioning” usually means solar-powered standard AC rather than a fundamentally different technology. Solar PV paired with an efficient AC system or heat pump is the most practical way to run cooling Read more »
Solar access rights protect a solar system owner’s ability to receive sunlight without a neighbor’s new tree, structure, or addition blocking their panels. Most US states have some form of solar access or solar easement law, though protections vary widely from strong guaranteed rights to weak, voluntary arrangements. What Solar Access Rights Cover Right/Law Type Read more »
Smart inverters go beyond basic DC-to-AC conversion, providing grid support services and advanced monitoring that benefit both homeowners and the broader electrical grid. Smart inverters offer voltage regulation, frequency response, and remote monitoring capabilities that basic inverters lack. Smart Inverter Features Feature Benefit Voltage regulation Helps stabilize local grid voltage fluctuations Frequency response Supports grid Read more »
Solar panels actually lose efficiency as they get hotter, which surprises many people who assume more sun always means more power. Understanding a panel’s temperature coefficient explains why hot, sunny days aren’t always a panel’s best-performing days. Why Heat Reduces Panel Output Solar cells are rated under Standard Test Conditions (STC) at 25°C cell temperature. Read more »
Rooftop solar remains the most common way homeowners generate their own electricity, converting sunlight into usable power right where it’s needed. A typical rooftop system costs $15,000-$25,000 before incentives and can offset most or all of a household’s electricity usage. Rooftop Solar System Types System Type Description Best For Grid-tied (no battery) Connects to utility Read more »
