These production values are for Apricus AP-30 collectors,
the savings estimates are based on NJ solar insolation levels provided by NASA.

Number of collectors =	(AP-30, thirty tube collectors )
Water Heater efficiency =	% (86 to 95% is average)
Cost of Electricity =	$ per kWh (usually 0.15 to 0.20)

When comparing other production values PLEASE NOTE the following variables that are incorporated into this program.

Solar insolation levels vary throughout the country depending on your latitude and local weather. A solar insolation level is simply the average daily amount of energy received in a specific region. This number is the average cumulative kWh/m²/day based on 22 year historical data. When comparing with other collector performance please compare "apples with apples" as we use this 22 year average and not the maximum possible daily output you could receive to calculate system production...after all not every day is sunny!

Because solar insolation levels vary from month to month this estimator uses data from the "Apricus System Sizing Program" to calculate the yearly average of Btu’s produced per day. This program takes into account the latitude, temperature, solar insolation levels, installation angle, sun angle throughout the year and collector efficiency . In NJ the average daily collector output throughout the year (including winter) is calculated to be 25,000 Btu –or- 25kBtu.

These calculations are based on a single AP-30 collector installed in NJ on a 40º angle facing due south. Collector efficiency is adjusted throughout the year to account for temperature and 1 kilowatt of electricity is calculated to equal 3,412 Btu.

Apricus collectors are among the most efficient on the market today so be sure to verify any claims of other collectors producing in excess of these collectors.
