All news →Common buying mistakes to avoid
Choosing wrong capacity
Calculate actual power needs first. Most buyers over- or under-size by 30–50%.
Ignoring roof space
Check roof area and sunlight hours before choosing panel size.
Undersizing inverters
Startup power is 2–3× running power. Always add 30% buffer.
Not comparing prices
Same product costs 15–30% more or less by season and platform.
