This comprehensive guide explains how to calculate solar panel costs, energy production, financial returns, and environmental benefits for your specific home or business. Our solar panel calculator simplifies complex calculations to help you make informed decisions about going.
Instantly estimate solar panel quantity, inverter capacity, and lithium battery storage size based on your daily power consumption and location's sunlight hours.
List each device → note its power (W) → estimate daily run‑time (hours) → compute Wh = W × hours → convert to kWh (Wh ÷ 1,000) and sum. Add 10–20% for “phantom”/future loads. Example (lean 2‑bed prefab): Look at the last 12 utility bills and note the highest‑use months (kWh).
Estimate the ideal spacing between rows of solar panels to minimize shading and maximize efficiency based on latitude, tilt, and panel height. Formula: Spacing = Height / tan (Solar Altitude).
Learn how to assess your home's critical electrical loads and design your solar setup to support them during an outage. Discover tips for maximizing solar production and extending battery runtime when the grid goes down.
