Solar myths persist despite falling prices and improving technology. Myths like “panels don’t work on cloudy days,” “solar requires batteries,” or “panels damage roofs” cost homeowners thousands in missed savings and delayed installations. This guide debunks 10+ common solar myths with facts and data. Contents1 Myth 1: Solar Panels Don’t Work on Cloudy Days2 Myth Read more »
The Balance of System (BOS) plays a vital role in the performance and efficiency of solar PV systems. While solar panels capture sunlight and convert it into electricity, the BOS components are responsible for the infrastructure and support systems that enable the smooth operation of the entire PV system. In this article, we will delve Read more »
Solar PV systems come in three main types: grid-tied (most common), off-grid (standalone with batteries), and hybrid (grid+battery). Each type has different costs, benefits, and use cases. This guide covers system types, performance characteristics, economics, and which type suits your situation best.

When you install solar panels, they generate power during daylight hours. But what happens when your panels produce more electricity than your home uses? Historically, homeowners simply let that excess power flow back to the utility grid. Today, most of the US has adopted net metering — a billing mechanism that credits your account when Read more »
Oversizing a solar system—installing more capacity than needed to cover 100% of annual consumption—can increase long-term returns if your utility offers favorable net metering. However, some utilities penalize overproduction, making right-sizing more important. This guide covers oversize analysis, economics, and when oversize makes sense. Oversize Economics With favorable net metering (full retail credits for excess), Read more »
Solar quotes are not created equal. Two installers might propose 5 kW systems on the same house with dramatically different equipment brands, labor structures, and final pricing. One might quote $3.00 per watt, another $4.50/watt. Without understanding what’s bundled into each quote — and knowing what industry-standard costs look like — you risk overpaying by Read more »
You’ve installed a solar battery to store daytime generation for evening use. But how long does it actually take to charge that battery from empty to full? The answer depends on three factors: battery capacity (in kilowatt-hours), your solar array size (in kilowatts), and the amount of available sunlight. A 10 kWh Powerwall paired with Read more »
Rooftop solar is the default for most homeowners, but it’s not the only option. Pole-mounted systems place an array on a single or multi-pole structure on the ground, typically 8-15 feet tall. For properties with unshaded acreage, roofs too old or weak to support panels, or roofs facing the wrong direction, pole mounting is a Read more »
You check your solar monitoring app and notice something alarming: your system’s output is zero or far below what it should be. The sun is shining brightly, but your panels aren’t generating power. Before calling your installer and paying a service visit fee, you can troubleshoot several common issues yourself. Most problems fall into a Read more »
Liquid solar panels is a broad term for several emerging photovoltaic technologies that involve liquids—from colloidal quantum dots suspended in liquid, to perovskite solar inks, to concentrating solar systems that use molten salt or synthetic oil as heat transfer fluid. The term is often misunderstood: “liquid solar panels” doesn’t exist as a single product you Read more »
