Question 1

How much does commercial solar cost in Lewisville, TX?

Accepted Answer

Commercial solar in Lewisville costs approximately $2.50-$3.00 per watt before incentives. A typical 375 kW system for a warehouse runs around $637,500 gross, dropping to $310,781 after the 30% Federal ITC, MACRS depreciation, and Texas property tax exemption.

Question 2

Is commercial solar worth it in Lewisville?

Accepted Answer

Yes. With 5.0 peak sun hours per day and Oncor commercial rates around $0.102/kWh, Lewisville businesses typically see 4.4-4 year paybacks and 25-year savings between $2,187,676 and $2,646,382 depending on building type. Texas property tax exemption on solar adds ~$350,625 in lifetime savings.

Question 3

What incentives apply to commercial solar in Lewisville?

Accepted Answer

Lewisville 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 Lewisville have the fastest solar payback?

Accepted Answer

Cold storage facilities and manufacturing plants have the fastest paybacks (4-4 years) due to their high baseload electricity consumption. Warehouses pay back in 4.4-5.4 years. Retail and office buildings typically see 5.4-7 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 Lewisville?

Accepted Answer

A typical Lewisville 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 Lewisville?

Accepted Answer

Battery storage is optional but increasingly popular in Lewisville 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 Lewisville commercial projects start solar-only and add batteries later.
