Solar panels.

For congregations, panels cost a lot and their payback period is prohibitively long*

* Because congregations don’t pay taxes, they don’t benefit from the 30% tax credit.

…which presents an opportunity.
Might tying energy conservation to solar panels make an enticing combination –both cost-effective and exciting?
![Page 9: How to help deep energy conservation take flight?](https://reader036.vdocuments.us/reader036/viewer/2022062516/56812a93550346895d8e43f2/html5/thumbnails/9.jpg)
Tying panels to deep energy conservation could shorten the payback for panels to just eleven years. Much shorter.

Break-even in eleventh year

But still out of reach. Congregations often need to recoup their investments very quickly – in perhaps seven years or less.
Might we get to seven or less by also tying panels to conservation by congregants - and by providing a modest grant?

Break-even in six years
Yes! With a $5000 grant and sixty members contributing half their energy savings for three years, the payback shrinks to six years.

Affordable solar – simply conserve.

Here are our assumptions.
Congregation Average congregant householdBase year annual electricity cost $5000 $900
Base year annual natural gas cost $3700 $900
Amount of energy conservation 17% 14%
Cost per watt of solar panels $3.40 Annual increase in electricity cost* 6%
Annual kWh generation per installed watt 1.13 Annual increase in natural gas cost 0%
Base year cost per watt from grid $.10 Congregant contribution of energy savings** 50%
* Based on Indiana Utility Forecasting Group projections.** Three years only. $70 a year.

And here are our results,Solar panels funded solely by a $5,000 grant and $23,000 in energy savings recouped in six years.
