Solar panels in Lake Havasu City, AZ

Check your specific roof in Lake Havasu City → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical Lake Havasu City solar system costs
A 16-panel system (6.4 kW) is about right for an average Lake Havasu City home using 10,800 kWh a year. It would produce roughly 10,864 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 5,432 | $6,384 | $826 | 7.7 yrs |
| 12 panels | 4.8 kW | 8,148 | $9,576 | $1,238 | 7.7 yrs |
| 16 panels | 6.4 kW | 10,864 | $12,768 | $1,644 | 7.8 yrs |
| 20 panels | 8 kW | 13,580 | $15,960 | $1,747 | 9.1 yrs |
| 26 panels | 10.4 kW | 17,653 | $20,748 | $1,902 | 10.9 yrs |
Notice that payback barely improves as systems get bigger, and eventually gets worse. That's because you can only save money on electricity you were going to buy anyway. Once a system covers your usage, extra panels mostly generate exports at a much lower rate.
Why Lake Havasu City gets 1,997 sun hours
That figure comes from Google's analysis of real rooftops across Lake Havasu City — it already accounts for shading from trees, chimneys and neighbouring buildings, which is why it's lower than the raw "hours of daylight" figures you'll see elsewhere. An unusually open, unshaded roof in Lake Havasu City reaches about 2,095 hours, roughly 5% better than typical.

When Lake Havasu City actually produces
Annual totals hide the thing that catches people out: 34% of Lake Havasu City's yearly sunlight arrives in May–July, and just 15% across November–January.
| Month | Sun hrs | Share of year |

Output is unusually steady — only about 2.4× between Jun and Dec. Lake Havasu City is close enough to the equator that seasonal variation is mild, which makes sizing a system considerably more predictable.
The annual total is measured from Google's rooftop imagery. Its split across months is calculated from solar geometry at Lake Havasu City's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
