PSNH Utility Bill: 05/01/2010

PSNH Bill
The PSNH billing software can't generate a graph if any month has excess generation nor can they display the meter reading info. I have to get them to email me the meter reading info. Every month that we have excess generation, they also send us a letter telling us what our current generation credit is in kWh. Update 08/06/10: PSNH has implemented my request to put the actual meter readings on the credit leter!

When we installed the solar pv system, our average daily usage was 37 kWh (1100 kWh/month). We've made some changes (reduced the number of PCs that are on, changed to highly power efficient PCs, smaller and more energy efficient fridge, etc) and have gotten this down to 21 kWh/day (639 kWh/month) in the summer.
