2016 Jan thru Apr

Update as of September 30, 2016

  • Calendar Year to Date 89% of all energy consumed thru the end of August 2016 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 both our interior and exterior lights for longer periods.
  • You may have noticed that we installed some window tinting on the south and west facing windows in the hall and rectory. This window treatment will reduce the solar gain and reduce the amount of air conditioning that we will need. Some of the windows and doors in the downstairs classrooms now have a security film on them which would make it more difficult to break and enter.
    Our next project is to replace all of the parking lot lights, all of the sanctuary lights and all of the exterior lighting on the church to LEDs. We will take 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.
  • YTD 2016 we received – $6,774 in incentive payments from the state of California.
  • In 2015 we saved approximately $31,980 in the cost of electric from SDG&E.
  • Estimated saving YTD for 2016 is $31,4657.

 

  • 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 one year 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.
