Each manufacturer has its strengths and weaknesses, so it is important to choose a panel based on the points you want to prioritize... *The material is from the booklet "Oshiete! Hakkutsutai!"*
Points to Consider When Choosing Solar Panels (1) Price The price is often compared not by how cheap it is, but by the cost per watt. This is to assess the cost performance relative to the power generation capacity. (2) Conversion Efficiency and Self-Generation Capacity Conversion efficiency is calculated as [Nominal Maximum Output of the Module (W)] ÷ [Module Area (m²) × 1000 W/m²]. This represents the power generation per unit area. (3) Actual Power Generation Some manufacturers focus on actual power generation, ensuring that the output does not decrease even in shadowy or cloudy conditions. ★ Right now, you can download the booklet "Basic Knowledge for Introducing Solar Power Generation Systems" for free. ★ ≪Contents Included≫ - What is a solar power generation system? / How solar power generation works - Types of solar panels and how to choose them - Power generation simulation - Annual forecasted power generation across the country - Installation examples - Benefits of having over 10 kW - Regarding selling electricity and more.
