A rooftop project with two purposes In the early 2000s The Green Project in New Orleans installed a rooftop solar photovoltaic (PV) system as an explicit experiment in both onsite energy and public education. The installation was framed at the time as a small, grid-connected demonstration: a way to reduce purchased electricity for a nonprofit … Read more

Small-scale solar projects can be rewarding and practical when scoped correctly. This guide explains the difference between fabricating a DIY PV module and assembling a safe, small off-grid or portable solar system from commercial parts. It focuses on realistic use cases (sheds, RVs, workshops, lighting), how to size a system, which components you need, important … Read more

Quick summary The credit commonly called the “residential energy tax credit” is officially the Residential Clean Energy Credit under Internal Revenue Code §25D. For qualified clean-energy property placed in service through December 31, 2025, the credit generally equaled 30% of qualified costs. Under Public Law 119-21 (enacted July 4, 2025), new §25D expenditures made after … Read more

Introduction: Solar can help, but it isn’t one-size-fits-all Rooftop solar photovoltaic (PV) systems can produce electricity for your home, lower the amount you buy from the utility, and reduce operational emissions. Whether it’s worthwhile depends heavily on your roof, local sunlight, utility rules, and how you plan to pay for the system. This article explains … Read more

Solar pool heating uses solar thermal collectors—typically unglazed polymer or rubber panels—to heat pool water by routing filtered water through channels warmed by sunlight. These collectors transfer heat directly to the water; they are not photovoltaic (PV) modules that generate electricity. Proper planning covers collector sizing, siting, plumbing integration, controls, freeze protection, and permits rather … Read more

What are Robotikits? Robotikits (sold by OWI Inc., dba RobotiKits Direct) are small, build‑your‑own educational toys that use a tiny photovoltaic (solar) cell to power a DC motor and simple mechanical motion. Often marketed as “mini‑solar kits,” these snap‑together models demonstrate how sunlight becomes motion and are positioned as beginner STEM/STEAM projects for classroom and … Read more

The “hybrid car” analogy — misleading in one way, useful in another Some critics have called Nevada Solar One a “hybrid” between solar and fossil fuel, implying that natural gas is the plant’s real engine while sunlight is a secondary assist. That characterization overstates the role of natural gas. Nevada Solar One is a concentrating … Read more
