Tax-Exempt Church, Direct Pay, and a Roof That Cannot Carry the Array

A tax-exempt entity may be able to elect direct payment for the investment tax credit on eligible solar property, but it is not automatic and it is not a salesperson’s tax opinion. The church must confirm eligibility with tax counsel and file the required election and return. The 30% rate depends on the project meeting the applicable labor and domestic-content rules, or qualifying for an exception. A 50 kW project may fall under a small-project exception to some labor requirements, but that must be verified for the tax year and property type-do not assume it.

Direct pay is also a cash-flow issue. The church may need to fund the full project first and receive the credit later, so bridge financing or donor timing matters. A power purchase agreement shifts ownership and tax attributes to a third party, but the church may lose direct-pay value and some control; a lease or PPA may also affect utility interconnection and net-metering treatment. Compare ownership with direct pay against a PPA on net cost, risk, and timing.

The donor offer should be documented, and the church should not treat the 30% as a discount at point of sale. Present the incentive as an estimated post-filing benefit subject to tax counsel, and show a downside case where the credit is delayed or reduced.

The structural engineer allows 4 psf additional dead load, but the proposed ballasted system is 6 psf. That is a 50% overstress relative to the stated allowance, so the system cannot be installed as designed. Do not treat the 2 psf difference as a minor field adjustment. Options include a lighter mounting system with fewer ballast blocks, adhered or mechanically attached mounts, structural reinforcement, or a smaller array. Penetrations may solve the weight issue but can affect the 5-year roof warranty and create leak risk.

The roof membrane has only 5 years of warranty left, and the HVAC unit may be replaced in 5 years. Installing PV now means either planning a removal and reinstall or coordinating the roof and HVAC work first. A roof-first plan adds cost but avoids a likely future removal. If the church proceeds now, require a roof consultant’s letter, a manufacturer-approved mounting detail, and a written maintenance access plan around the HVAC unit.

The sales recommendation should be: do not sign a construction contract until the structural and roof-warranty issues are resolved. Present three options-roof replacement plus PV, a lighter non-penetrating system with reduced ballast, or a smaller array on the strongest roof areas-with lifecycle costs. Hiding the engineer’s 4 psf limit would be indefensible.

The net-metering program is 85% subscribed, so the church may or may not secure the current tariff depending on the queue and the utility’s acceptance date. Do not promise net metering. Ask the utility for the current queue position, the program rules, and whether a complete interconnection application locks in the tariff. If the cap fills before acceptance, the project may be compensated under net billing, where exports are credited at avoided cost rather than retail.

Model savings under both tariffs. Under net metering, export credits offset retail consumption; under net billing, only self-consumed energy gets full retail value and exports get a lower credit. A 50 kW array may export heavily on Sundays and low-load days, so the net-billing case could be much worse. Size the array to the church’s daytime load or add load shifting if self-consumption is low.

Present a sensitivity table: net metering, net billing, and a delay scenario. Include a contract clause that savings estimates are not guaranteed and that utility tariffs can change. If the church cannot accept tariff risk, a third-party PPA may transfer some risk, but the church should compare the PPA price and escalator against the ownership case. The decision should be based on the downside tariff, not only the current net-metering benefit.
