Update as of October 30, 2017
- Calendar Year to Date 92% of all energy consumed through the end of September 2017 was produced by Solar at OMC. Now that the days are getting shorter there are less hours of sunlight so we do not produce as much energy via our solar system. We will also be using our interior and exterior lights for longer periods.
To lower the heat gain and provide another level of security we installed security window tinting on the south and west facing windows in the hall and rectory. This window treatment will reduce the solar gain which will reduce the amount of air conditioning and will make it more difficult to break and enter.
All of our exterior building and parking lot lights have been changed to energy saving LEDs. We took advantage of $7,500 in rebates from SDG&E and will use SDG&E’s On Bill Financing program to fund this $30,000 project. Payback is expected to be less than 3 years. These new LED lights are 80% more efficient and will not have to be replaced for at least 15 years, saving much time, effort and expense.
- We will continue to monitor the outdoor temperatures and adjust our HVAC as necessary to keep everyone comfortable. When the temperature is mild, there is no need for fans or air conditioning.
- In addition to saving money on our electric bills, we receive an incentive from the state of California of $.114 per kWh produced by Solar for the first 5 years that our system is in operation.
- In 2015 we received $9,423 in incentive payments from the state of California.
- In 2016 we received – $10,269 in incentive payments from the state of California.
- YTD 2017 we earned $7,891 in incentive payments from the state of California.
- we saved $44,233 in the cost of electric from SDG&E.
- In 2016 we saved $41,220.
- YTD 2017 we saved $27,689
- In Aug 2014 we paid $188,850 for our 152 panel system using Sunpower 327w panels.
- Our system was approved and connected to the grid in Nov 2014.
- Estimated payback after analyzing 2 1/2 years of data is now less than 4.5 years.
As good stewards of the resources that are given to us, our goal is to reduce our demand and overall consumption. This will take some further behavioral changes, light fixture and bulb replacement and careful monitoring.
