How to Use This Calculator

Enter your kennel runs and HVAC tonnage

Kennel run count and HVAC tonnage are the two critical inputs for pet boarding solar sizing. Boarding facilities require strict temperature control — 68-72°F for dogs, 70-75°F for cats — year-round. Unlike offices or retail that reduce HVAC after hours, boarding kennels maintain full HVAC 24/7 when occupied. The calculator estimates HVAC load at 1.2 kW per ton of capacity — an industry-standard figure for commercial HVAC systems. Enter your nameplate cooling tonnage from equipment data plates or from your HVAC contractor.

24/7 boarding vs. daycare-only operation

This toggle significantly changes solar economics. 24/7 boarding facilities use 40% of their electricity at night when solar produces nothing — requiring net metering or battery storage to capture full solar value. Daycare-only operations (no overnight stays) have loads concentrated in 8am-8pm hours, aligning well with solar production and enabling 75-85% solar self-consumption without batteries. The calculator models both scenarios. For 24/7 facilities, net metering (available in most states) allows daytime solar credits to offset nighttime draws at full retail value.

Grooming stations and outdoor lighting

Professional grooming dryers are the highest-power intermittent loads in a boarding facility — high-velocity dryers run 1,500-2,500W each. Each grooming station (dryer, clippers, hot water, tub) uses about 600 kWh/month of electricity. Outdoor play yard lighting (LED) adds about 300 kWh/month and enables evening play sessions — valuable in summer when daytime heat limits outdoor activity for dogs. Include these loads for accurate sizing.

The Formula

Load Estimate (monthly kWh): HVAC: tons × 1.2 kW/ton × hours/day × 30 24/7 boarding: 24 hrs/day Daycare only: 12 hrs/day Kennel lighting/heating: runs × 30 kWh/run/month Grooming: stations × 600 kWh/station/month Hot water (kennel washing): runs × 15 kWh/run/month Play yard lighting: 300 kWh/month (if enabled) Roof Area = kennel runs × 150 sq ft Max System kW = Roof Area ÷ 80 sq ft/kW Annual kWh Used = Annual Bill ÷ (State Rate / 100) System kW = min(kW for full offset, Max kW) Annual kWh Generated = System kW × PSH × 365 × 0.80 Annual Savings = Annual Bill × Offset % Gross Cost = System kW × 1,000 × $2.80/W ITC = Gross Cost × 30% Year 1 MACRS Savings = (Gross Cost − ITC×50%) × 24% × 25% Payback = (Gross Cost − ITC − MACRS) ÷ Annual Savings Eco Premium = Runs × $50/night × 80% occupancy × 365 × 10%

The eco-boarding marketing premium assumes a conservative 10% rate premium over non-solar competitors at $50/night average and 80% occupancy. Premium boarding resorts in affluent markets may achieve 15-20% premiums with robust sustainability marketing. The premium is additive to electricity savings but requires active marketing investment to realize.

Example

Pawsaway Pet Resort — 50-suite boarding facility, Florida

A 50-suite boarding facility in Florida with 15 tons HVAC, 3 grooming stations, outdoor play yard lighting, 24/7 operation. Monthly electricity bill: $4,500.

Kennel runs/suites50 suites

Result

System size~50 kW (125 × 400W panels)
Energy offset~70% (net metering for night loads)
Annual savings~$37,800/yr
Gross cost$140,000
ITC (30%)-$42,000
Year 1 MACRS savings-$13,000
Effective cost$85,000
Payback~2.2 years
Eco-boarding premium~$73,000/yr at 10% higher rate

Florida's year-round AC demand makes boarding facilities ideal solar candidates. The 2.2-year payback is exceptional. Adding the eco-boarding marketing premium to realized rate increases transforms this into a business growth investment, not just a utility cost reduction project.

FAQ

Pet boarding facilities are excellent solar candidates because their primary load — HVAC — runs year-round without the seasonal dips seen in office buildings or retail. A boarding kennel in Florida runs air conditioning 12 months per year; one in Minnesota runs heating in winter and AC in summer. Both create consistent annual electricity demand that solar can offset. The MACRS + ITC combination (30% ITC + year-one depreciation tax savings = typically 40-50% effective cost reduction) creates paybacks of 3-7 years for commercial boarding facilities.
24/7 boarding means approximately 40% of electricity consumption occurs at night when solar produces nothing. Two solutions: (1) Net metering — available in most states, allows daytime solar production to bank credits on the utility meter that offset nighttime draws at a 1:1 or near-1:1 ratio. This is the simplest and often most economical approach. (2) Battery storage — sized for 30-50% of nighttime load, captures daytime solar production for nighttime use without grid dependency. Battery payback is typically 8-12 years currently, improving as costs decline. Net metering is recommended as the first step; battery storage as a second-phase investment.
Pet owners are among the most values-driven consumers. A 2024 survey found 68% of pet owners prefer pet services from environmentally responsible businesses, and 41% would pay more for "green" boarding. Solar provides tangible proof points: kWh generated per dog-night stayed, CO2 offset per year, equivalent trees planted. Boarding facilities that prominently market solar — "Your pet's stay powered by solar energy" — can command 10-20% premium rates in competitive markets. For a 100-suite resort at $75/night doing 80% occupancy, a 10% rate premium adds $219,000 annually.
Solar is most directly valuable for summer cooling because peak production aligns with peak AC demand. In Florida, Texas, and Arizona, year-round AC creates year-round solar value. Northern facilities (Michigan, Ohio, Minnesota) see maximum solar benefit in summer and often use natural gas, propane, or heat pump heating in winter — reducing electric heating load. The calculator models your state's annual average PSH and electricity rate, which already account for seasonal variation. Summer months typically generate 150-200% of winter production for northern facilities.
The critical difference is 24/7 HVAC. A grooming-only salon operates 8-10 hours per day and powers down HVAC overnight — similar to retail. A boarding facility's HVAC, lighting, and security run continuously when dogs are present (typically 90%+ occupancy means near-continuous operation). This increases monthly kWh consumption by 50-80% compared to a grooming-only business of equal square footage. Use the pet grooming calculator for salons without overnight boarding.
