How to Use This Calculator

Enter your monthly bill and select your utility

NV Energy serves approximately 90% of Nevada including Las Vegas, Henderson, Reno, and Sparks. Valley Electric serves Pahrump and surrounding areas. Enter your average monthly bill — in Nevada, summer air conditioning can make July-August bills 2-3x higher than winter. Using a 12-month average gives the most accurate sizing.

Enter system size and check incentives

Nevada's 6.2 peak sun hours is the 2nd highest in the US, meaning every kilowatt of solar produces approximately 1,810 kWh per year. An 8 kW system in Las Vegas covers most 2,000-2,500 sq ft home usage. The calculator automatically applies Nevada's retail-rate net metering (through 2026), property tax exemption, and sales tax exemption.

Understand the incentive stack

Nevada solar buyers benefit from three financial incentives: (1) 30% federal ITC on the full system cost, (2) 100% property tax exemption — your home's assessed value does not increase when you add solar, and (3) sales tax exemption on solar equipment purchase (NRS 372.806). Together these reduce effective system cost by 35-40%.

The Formula

Monthly kWh = Monthly bill ÷ Electricity rate Annual production = System kW × 1,000 × 6.2 PSH × 365 × 0.80 Recommended kW = Monthly kWh ÷ (6.2 PSH × 30 days × 0.80) Net metering savings = Production × Retail rate (full retail, through 2026) Gross cost = System kW × 1,000W × $2.55/W ITC = Gross cost × 30% Net cost = Gross cost − ITC Property tax savings = System value × 0.94% × 20 years Sales tax savings = Equipment cost × 6.85% (NV avg) Payback = Net cost ÷ Annual savings

Nevada uses full retail-rate net metering under NRS 704.773, which is guaranteed through at least 2026. This means every kWh exported to the grid earns the full retail rate — significantly better than states where utilities pay wholesale rates for excess solar.

Example

Martinez family — Las Vegas, NV

The Martinez family in Las Vegas has an average monthly bill of $165 with NV Energy. They're considering an 8 kW system at $2.55/W.

Monthly bill$165/mo
UtilityNV Energy ($0.12/kWh)
System size8 kW (20 panels)
LocationLas Vegas, NV (6.2 PSH)

Result

Annual production~14,476 kWh/yr
Annual savings~$1,737/yr
Gross system cost$20,400
Federal ITC (30%)-$6,120
Sales tax exemption~$1,400 saved
Payback period~8.2 years
25-year savings~$43,400

Nevada's combination of 6.2 PSH (2nd in the US), low installation costs ($2.55/W), and strong net metering makes for excellent solar economics. The Martinez family recovers their net investment in ~8.2 years — then generates $1,700+ per year in pure savings for the remaining panel life.

FAQ

Nevada's net metering law (NRS 704.773) requires NV Energy to credit excess solar generation at the full retail electricity rate. Credits roll over monthly and settle annually. The full retail-rate program is guaranteed through at least 2026 for new systems installed during this period. NV Energy has previously proposed reducing net metering rates — installing now locks in the better retail-rate program. After 2026, the PUC may revise rates, but systems already enrolled typically grandfather in for 20 years.
Yes — Nevada provides a 100% property tax exemption for residential solar installations. When you add solar, the assessed value of your home for property tax purposes does not increase, even though solar systems typically add $10,000-25,000 in home market value. This exemption applies automatically — you don't need to file a special application. Nevada's effective property tax rate is about 0.94%, so on a $20,000 system, this saves you roughly $188/year in perpetuity.
Yes — Nevada exempts solar energy systems from sales and use tax under NRS 372.806. This applies to the purchase of solar panels, inverters, mounting hardware, and associated equipment. Nevada's statewide sales tax is 6.85% (higher in some counties), so on a $15,000 equipment purchase, this saves $1,000-1,200 at the point of purchase. Your installer should apply this exemption automatically — if they don't, ask them to correct the invoice before payment.
Nevada averages 6.2 peak sun hours per day, second only to Arizona at 6.5. The combination of low latitude, desert climate with minimal cloud cover, and low humidity (which reduces atmospheric scattering of sunlight) creates ideal solar conditions. Las Vegas receives about 294 sunny days per year. A 1 kW solar system in Nevada produces approximately 1,810 kWh/year, compared to 1,460 kWh in the national average location — 24% more energy from the same hardware.
Yes — solar panels lose efficiency at high temperatures, typically 0.3-0.5% per degree Celsius above 25°C (77°F). In Las Vegas summers where rooftop temperatures can reach 70-80°C (160-175°F), panels may operate at 10-20% below their rated output during peak afternoon heat. However, Nevada compensates with exceptional irradiance levels and long summer days — the net effect is still outstanding annual production. Monocrystalline panels have better temperature coefficients than polycrystalline and are the recommended choice for Nevada.
