Question 1

How much does commercial solar cost in Round Rock, TX?

Accepted Answer

Commercial solar in Round Rock costs approximately $2.50-$3.00 per watt before incentives. A typical 360 kW system for a warehouse runs around $612,000 gross, dropping to $298,350 after the 30% Federal ITC, MACRS depreciation, and Texas property tax exemption.

Question 2

Is commercial solar worth it in Round Rock?

Accepted Answer

Yes. With 5.1 peak sun hours per day and Oncor commercial rates around $0.104/kWh, Round Rock businesses typically see 4.3-3.9 year paybacks and 25-year savings between $2,174,584 and $2,609,501 depending on building type. Texas property tax exemption on solar adds ~$336,600 in lifetime savings.

Question 3

What incentives apply to commercial solar in Round Rock?

Accepted Answer

Round Rock commercial properties qualify for: (1) 30% Federal Investment Tax Credit (ITC), (2) 5-year MACRS accelerated depreciation, (3) 100% Texas property tax exemption on solar value (TX Tax Code § 11.27), and (4) potential USDA REAP grants for rural/agricultural property owners. These stack — a business typically recovers 45-55% of system cost in Year 1 tax benefits alone.

Question 4

Which building types in Round Rock have the fastest solar payback?

Accepted Answer

Cold storage facilities and manufacturing plants have the fastest paybacks (3.9-3.9 years) due to their high baseload electricity consumption. Warehouses pay back in 4.3-5.3 years. Retail and office buildings typically see 5.3-7 year paybacks. All five building types remain profitable over 25 years; the difference is how quickly capital is recovered.

Question 5

How long does commercial solar installation take in Round Rock?

Accepted Answer

A typical Round Rock commercial solar project takes 3-6 months from contract signing to operation. This includes engineering (2-4 weeks), Oncor interconnection approval (6-12 weeks — the longest step), permitting with the local jurisdiction (2-4 weeks), and installation (2-4 weeks for systems up to 500 kW). Larger systems or those requiring utility grid upgrades can take 6-9 months.

Question 6

Do I need battery storage with solar in Round Rock?

Accepted Answer

Battery storage is optional but increasingly popular in Round Rock given ERCOT grid instability since Winter Storm Uri. Batteries add $400-$800/kWh to project cost but enable: peak demand charge reduction (valuable on $8.5/kW demand-charged tariffs), backup power during outages, and time-of-use arbitrage. Most Round Rock commercial projects start solar-only and add batteries later.
