3 targeting system performance Determining estimated system performance is not an exact science. We aim to provide you with a realistic range of your system s expected performance. Many variables unique to your home are considered in our calculations. Knowledge of how we determine your system s estimated production will help you understand production fluctuations and maintain reasonable expectations of your system s performance. We do our very best to design a solution suited for your home and budget.

5 seasonal production curve Depending on the time of year, your ACTUAL monthly PV production will differ from the ANNUAL AVERAGE monthly PV production estimated for your system size. Actual production will fluctuate with seasonal changes in sun angle, length-of-day and weather conditions. Additionally, estimated system production may vary from year-to-year. For example, a rainy month this year may be a sunny one next year. In general, you will see higher production in summer months and reduced production in the winter. Determining the right system size is important because there is little benefit to producing more energy than you use in any twelve month period. SUMMER WINTER

6 PV USAGE A PV CREDITS B C UTILITY USAGE A B PV electricity delivered directly to your home excess PV electricity sent to the utility for credit utility power delivered back to your home C Your PV system production will always be greater than the Net Metering Credit shown on your utility bill, because the system is connected on the home side of your utility meter. The meter doesn t track the PV electricity used by your home, it only reports the excess energy that was sent out of your home, to the utility. Typically, during the day, some of the electricity your system produces will be sent to the utility for credit. During cloudy days, you may consume all of the electricity your system produces and may even need a little extra from the utility, while at night, when your system is not making electricity, you will receive all of your electricity from the utility. net metering
