How to Use This Calculator

Facility size and refrigeration units

Funeral homes have a unique electrical load profile dominated by two critical systems: morgue refrigeration and precision HVAC. Enter your facility size and the number of commercial refrigeration units. Each refrigeration unit draws approximately 500W continuously, 24 hours a day, 365 days a year — this is a non-negotiable load that cannot be reduced or scheduled. Morgue refrigeration represents the most solar-compatible load type: it's constant, predictable, and benefits directly from solar's daytime generation supplementing baseload consumption.

Crematorium presence — important distinction

If your facility has cremation services, select the crematorium option. Traditional retort cremators operate at 1,400–1,800°F using natural gas — they cannot be powered by solar electricity. Solar panels and cremation equipment are not directly connected. However, solar still meaningfully offsets your facility's electrical loads (refrigeration, HVAC, lighting, office equipment). Selecting the crematorium option adjusts the calculation to account for gas-driven cremation costs being separate from electrical savings.

Viewing rooms and HVAC

Viewing and visitation rooms require precise temperature and humidity control regardless of outside conditions — families expect comfort during services. HVAC for funeral homes is typically sized at 1 ton per 500 sq ft, similar to commercial office space, but must maintain consistent conditions year-round. Viewing rooms also have AV equipment for memorial services and, increasingly, livestreaming capabilities for remote family members.

The Formula

Refrigeration Load kW = Units × 0.5 kW (500W per unit, 24/7) HVAC Load kW = (Facility sq ft ÷ 500) × 1.2 kW/ton Viewing Room Load kW = Rooms × 1.5 kW Embalming Room Load kW = 4.0 kW (fixed estimate) Electrical Fraction = 100% (no crematorium) | 70% (with crematorium) Annual kWh Used = Annual Bill × Electrical Fraction ÷ (Rate/100) Usable Roof = Facility sq ft × 60% System kW = min(kW for full offset, Max from roof) Annual Savings = Annual Bill × Electrical Fraction × Offset % ITC + MACRS Year 1 = Combined first-year tax benefit Payback = Effective Cost ÷ Annual Savings

The 60% roof efficiency factor for funeral homes reflects that many facilities have architectural elements (porticos, dormers, decorative rooflines) that reduce usable panel area below what a standard commercial building would offer. Funeral homes also often have lower rooflines and setbacks to maintain an appropriate residential aesthetic in their neighborhood context. Even so, most funeral homes have sufficient roof area for a 10–40 kW system that meaningfully offsets electrical costs.

Example

Heritage Funeral Services — 8,000 sq ft, Ohio, 8 refrigeration units

Heritage Funeral Services operates an 8,000 sq ft funeral home in Ohio with 8 commercial refrigeration units, 4 viewing rooms, no on-site crematorium, and a $2,800/month electricity bill.

Facility size8,000 sq ft
Refrigeration units8 × 500W = 4 kW continuous
Viewing rooms4
Monthly bill$2,800/mo ($33,600/yr)

Results

System size~22 kW
Energy offset~75%
Annual savings~$25,000/yr
Gross system cost~$61,600
First-year tax benefit (ITC + MACRS)~$24,200
Effective cost~$37,400
Payback~1.5 years
25-year NPV~$284,000

Heritage's 1.5-year payback reflects a near-ideal solar scenario: moderate system size, high electricity rate, and a consistent refrigeration load that directly benefits from solar offset. The $284,000 25-year NPV transforms a $61,600 investment into substantial long-term value — meaningful for a family-owned business planning generational continuity.

FAQ

Yes — funeral homes are increasingly adopting solar as part of a broader sustainability and modernization strategy. The financial case is sound: funeral homes have consistent electrical loads (refrigeration, HVAC), moderate-to-large flat or low-slope roofs, and qualify for business tax incentives (ITC + MACRS depreciation). The growing green burial movement and consumer interest in environmentally conscious death care create marketing opportunities. The National Funeral Directors Association (NFDA) has reported growing consumer interest in green and sustainable funeral services. Solar-powered facilities can authentically market as environmentally responsible while reducing operating costs.
Traditional retort cremation chambers operate at 1,400–1,800°F using natural gas burners — this thermal energy requirement far exceeds what solar electric panels can provide. A single cremation cycle uses 15–30 cubic feet of natural gas. Solar panels generate electricity, not thermal energy, so they cannot directly fuel the cremation process. However, solar can offset the electricity consumed by the crematorium's control systems, ventilation fans, and auxiliary equipment — typically 2–5 kW of electrical load per cremation. Electric cremation technology (using microwave or other electric heating) exists but is rare in the US market as of 2026.
The intersection of solar energy and death care is genuinely meaningful to a growing segment of families. Key marketing angles: (1) Green burial alignment — solar complements natural burial, biodegradable caskets, and other eco-friendly options as part of a holistic sustainability offering. (2) Dignity in operations — solar demonstrates that the facility operates with minimal environmental footprint, which resonates with families who view end-of-life care as a values statement. (3) Legacy messaging — "the last service we provide is also sustainable" connects powerfully in planning conversations. (4) Community trust — funeral homes are community institutions; visible sustainability investment signals long-term commitment to the community.
Battery storage deserves serious consideration for funeral homes for a specific reason: morgue refrigeration is a critical, non-interruptible load. A grid outage that disables refrigeration for more than 4–6 hours can create catastrophic problems. A battery storage system sized to power refrigeration units during outages (typically 4–15 kWh depending on unit count) provides meaningful business continuity insurance. Many funeral home operators in storm-prone regions (Florida, Gulf Coast, coastal Northeast) have added batteries specifically for this backup use case, even where the savings-based ROI alone wouldn't justify the investment. The combination of solar-charged batteries and generator backup provides complete refrigeration resilience.
