Most solar lighting systems use fixtures ranging from 20 Watt LED (2000+ Lumens) to 90 Watt LED (9000+ Lumens) and are typically in the 35 Watt to 50 Watt range for most applications. High security or light level requirements use the brighter lights and residential and remote areas use the lower range.
Wattage refers to the amount of electrical power a solar panel can produce under standard test conditions (STC), which simulate a bright sunny day with optimal solar irradiance (1,000 W/m²), a cell temperature of 25°C, and clean panels. In simpler terms, a panel’s wattage rating tells you its maximum power output under ideal conditions.
Solar panels are rated by their peak DC power under ideal test conditions. Homeowners use AC electricity, so inverters convert DC to AC with a small efficiency loss (around 3–5%). Over the past decade, panel wattage has climbed steadily. Here’s a snapshot of what’s common now: 250–300 W: Older or budget-friendly modules.
A 400-watt panel can generate roughly 1.6–2.5 kWh of energy per day, depending on local sunlight. To cover the average U.S. household’s 900 kWh/month consumption, you typically need 12–18 panels. Output depends on sun hours, roof direction, panel technology, shading, temperature and age.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
