Model comparison of 12V Solar DC Freezer
Manufacturing Exporter
Since all the models reviewed are similar in size,
the main cost difference is related to the ampere-hours consumed by the battery
each day. As mentioned earlier, if a generator or utility grid power can be used
to keep the battery fully charged, I recommend using the lower cost marine or RV
model. However, if solar panels are the main power source for charging the
battery, then I strongly recommend models with very low ampere-hour
requirements, and in most cases, these models will be the most
expensive.
Solar requirements
Unless you live in extremely cold northern
latitudes with short sunshine hours and low sun angles, most parts of the United
States have an average of 4 to 4.5 hours of direct sunlight per day in winter
and 5 to 6 hours per day in summer. Of course, some milder geographic locations
may also have a lot of rainfall and cloud cover, which will reduce these average
hourly values.
