For congregations, panels cost a lot and their payback period is prohibitively long* Break-even in 18th year * 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?
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. What’s not to like?
Here are our assumptions.

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