Solar System Size Breakdown

Your monthly electric bill is used to estimate how much solar electricity you would need based on typical utility rates in your area.

A 2.8kW solar system will cover about 94% of your electricity usage.

A 3.5kW solar system will cover about 98% of your electricity usage.

A 5kW solar system will cover about 97% of your electricity usage.

A 6.8kW solar system will cover about 99% of your electricity usage.

Cost of Solar Systems

Largest lifetime savings can be had by purchashing your solar system in full upfront. By doing this, you will be the outright owner, which means you may claim any local, state, or federal incentives in place.

A 2.8kW solar system will cost $13,223 (before federal tax incentives)

Total payments over 20 years:

Maintenance: $0

Remaining utility bills assuming 2.2% annual price increases: $4,323
Total: $13,223 + $4,323 = $17,546

State and Federal Incentives

Federal Investment Tax Credit (ITC): $3,438
State tax credit: $0
$17,546 – $3,438 = $14,108

Total 20-year cost with solar

Includes above costs and incentives: $14,108

Total 20-year cost without solar

Assumes 2.2% annual increase in electricity prices: $23,511

Total 20-year savings

Net present value at 4% discount rate: $3,284.

$23,511 – $14,108 = $9,402

You would save $9,403 in 20 years by installing a 2,8kW solar system.

A 3.5kW solar system will cost $15,263 (before federal tax incentives)

Total payments over 20 years:

Maintenance: $0

Remaining utility bills assuming 2.2% annual price increases: $3,898
Total: $15,263 + $3,898 = $19,161

State and Federal Incentives

Federal Investment Tax Credit (ITC): $3,968
State tax credit: $0
$19,161 – $3,968 = $15,193

Total 20-year cost with solar

Includes above costs and incentives: $15,194

Total 20-year cost without solar

Assumes 2.2% annual increase in electricity prices: $29,520

Total 20-year savings

Net present value at 4% discount rate: $6,152

$29,520 – $15,194 = $14,326

You would save $14,326 in 20 years by installing a 3.5kW solar system.

A 5kW solar system will cost $19,343 (before federal tax incentives)

Total payments over 20 years:

Maintenance: $0

Remaining utility bills assuming 2.2% annual price increases: $5,190
Total: $19,343 + $5,190 = $24,533

State and Federal Incentives

Federal Investment Tax Credit (ITC): $5,029
State tax credit: $0
$24,533 – $5,190 = $19,343

Total 20-year cost with solar

Includes above costs and incentives: $19,505

Total 20-year cost without solar

Assumes 2.2% annual increase in electricity prices: $44,542

Total 20-year savings

Net present value at 4% discount rate: $12,471

$44,542 – $19,505 = $25,037

You would save $25,037 in 20 years by installing a 5kW solar system.

A 6.8kW solar system will cost $24,103 (before federal tax incentives)

Total payments over 20 years:

Maintenance: $0

Remaining utility bills assuming 2.2% annual price increases: $4,839
Total: $24,103 + $4,839 = $28,942

State and Federal Incentives

Federal Investment Tax Credit (ITC): $6,266
State tax credit: $0
$28,942 – $6,266 = $22,676

Total 20-year cost with solar

Includes above costs and incentives: $22,676

Total 20-year cost without solar

Assumes 2.2% annual increase in electricity prices: $59,565

Total 20-year savings

Net present value at 4% discount rate: $19,405

$59,565 – $22,676 = $36,889

You would save $36,889 in 20 years by installing a 6.8kW solar system.

What if All Homes in Los Angeles Installed Solar?

If all solar viable homes were to install a solar system, the amount of avoided CO2 emissions from the electricity sector in Los Angeles would be the equivalent of the below metrics. (Please note that each metric is singular, therefore; 4.2 million metric tons of Co2 = 891,000 passenger cars off the road, which = 108M trees planted, which = 2.1 million less humans.) These metrics are updated as soon as new information becomes available.
4.2M Metric Tons
of carbon dioxide would be removed from our planets atmosphere. Energy consumption is the biggest source of human-caused greenhouse gas emissions, responsible for an enormous 73% worldwide.
108M Trees Planted
would be planted throughout the city, each one with the ability to absorb the CO2 that we emit on a daily basis.
891K Passenger Cars
would essntially be removed from the streets of Los Angeles for 1 year. Currently Los Angeles has roughly 7,931,003 registered auto vehicles.
2.1M Less Humans
Each human produces about 2 tons of CO2 a year. The amount of carbon reduced by installing solar systems on every home in Los Angeles would be the equivalent of reducing the cities population by 2.1 million people.
