How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For a dog house fan, safety means the weather ratings and protective nets the listing actually states; two state IP ratings and two state protection nets. Only one of the five states a warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| pqins Dual Fan | 9.7 | 30 | 22 | 20 | 6 | 3 |
| HNRLOY 4-Fan | 9.6 | 32 | 24 | 20 | 5 | 0 |

| HASDSAGY 25W | 9.5 | 28 | 21 | 20 | 5 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

The pqins and NHZOTUD state 200 CFM from dual fans; the HNRLOY states 4×120.5 CFM from four fans; the DC HOUSE and HASDSAGY state no CFM figure. More fans spread the airflow; more CFM moves more air. See our best solar fan for chicken run picks for coop-sized kits.
