Before getting solar quotes, homeowners want to know whether their home is even a good candidate for solar. The Sun Number Score — sometimes called a SunScore — was designed to answer that question. Developed with funding from the Department of Energy and once prominently displayed on Zillow property listings, Sun Number Scores provide an Read more »
Solar air conditioning combines photovoltaic panels with AC systems to reduce or eliminate dependence on grid electricity for cooling. As climate change intensifies summer heat and energy costs rise, homeowners increasingly seek sustainable ways to keep their homes cool without excessive energy bills. Solar AC systems leverage abundant daytime sunlight to power air conditioning units, Read more »
Solar access rights are legal protections that allow property owners to maintain unobstructed access to sunlight for solar panels. As the solar industry grows, disputes over shading from neighboring trees, buildings, or structures increasingly affect system performance and ROI. Understanding solar access rights and solar easements is essential for anyone installing or considering solar energy Read more »
Smart inverters (also called intelligent or advanced inverters) are solar inverters with grid-aware capabilities and two-way communication enabling real-time control and optimization. Unlike traditional string inverters that simply convert DC to AC power, smart inverters actively participate in grid operations, respond to grid signals, and support voltage/frequency management, making them essential technology for modern grid-integrated Read more »
Solar panel temperature directly impacts electrical efficiency and system lifespan. Most homeowners understand that sunlight powers solar panels, but fewer realize that excessive heat significantly reduces energy output. Understanding temperature coefficients and thermal management helps optimize solar system performance and longevity. Solar panels operate most efficiently in moderate temperatures between 45°F and 75°F (7°C to Read more »
Rooftop solar panels are the most common way homeowners go solar in America. They’re increasingly affordable, require no additional land, and can power most or all of your home’s electricity needs. This guide covers how rooftop solar works, what it costs, how much you’ll save, and whether your home is a good fit. How Rooftop Read more »
Solar panel replacement becomes necessary when panels degrade beyond acceptable performance levels, suffer physical damage, or become obsolete compared to newer, more efficient technology. While quality panels last 25–30 years with minimal degradation (0.3–0.8% annually), circumstances may warrant earlier replacement for economic or practical reasons. Understanding when and why to replace panels, the process, costs, Read more »
Renewable Portfolio Standards (RPS) are among the most powerful policies driving solar energy adoption in the United States. If you’ve heard the term “RPS” in conversations about energy policy, you may have wondered what it means and how it affects you. Understanding renewable portfolio standards is essential for grasping the policy landscape that makes solar Read more »
As solar energy systems become increasingly popular, it’s important to understand the factors that influence their performance and longevity. One critical factor is solar batteries’ depth of discharge (DoD). In this article, we will explore the significance of DoD in solar battery systems, its impact on battery performance and cycle life, and strategies to maximize Read more »
smart-solar-panels Smart solar panels integrate monitoring, microinverters, and communication technology to optimize energy production, detect faults in real time, and provide granular performance data. While traditional panels are simple and passive, smart panels add 10–15% cost but enable advanced features like per–panel optimization, automatic fault detection, and integration with home automation systems. Smart solar technology Read more »
