The costs of a solar system vary based on system size, panel quality, and additional components like batteries and inverters. On average, a small homestead solar system may cost between $10,000 to $25,000, but it may offer significant long-term savings.

To calculate the long-term benefits and payback of installing a solar system on a homestead, we need to consider several factors, including the cost of the system, energy savings, electricity rates, and incentives. Let’s assume an average monthly electricity bill of $150 and an annual electricity rate increase of 3%.

For the $10,000 Solar System:

1. Energy Savings:
   • Calculate the estimated annual energy savings using the solar system:
   • Assuming the solar system reduces the electricity bill by 80%, the annual energy savings would be: $150 (monthly bill) x 12 months x 80% = $1,440 per year.
2. Payback Period:
   • Determine the payback period by dividing the initial cost of the system by the annual energy savings:
   • Payback Period = $10,000 (cost of the system) / $1,440 (annual energy savings) ≈ 6.94 years.
3. Long-Term Benefits:
   • After the payback period, the homestead will continue to save $1,440 annually on electricity bills. Over 20 years, the total savings would be:
   • 20 years x $1,440 per year = $28,800.

For the $25,000 Solar System:

1. Energy Savings:
   • Calculate the estimated annual energy savings using the solar system:
   • Assuming the solar system reduces the electricity bill by 90%, the annual energy savings would be: $150 (monthly bill) x 12 months x 90% = $1,620 per year.
2. Payback Period:
   • Determine the payback period by dividing the initial cost of the system by the annual energy savings:
   • Payback Period = $25,000 (cost of the system) / $1,620 (annual energy savings) ≈ 15.43 years.
3. Long-Term Benefits:
   • After the payback period, the homestead will continue to save $1,620 annually on electricity bills. Over 20 years, the total savings would be:
   • 20 years x $1,620 per year = $32,400.

While the initial investment for a $25,000 solar system is higher, it will yield higher annual energy savings. However, the payback period for the $25,000 system is longer compared to the $10,000 system. Both systems offer significant long-term benefits, with the $25,000 system saving more over 20 years. The choice between the two systems depends on the homestead’s budget, electricity needs, and desired payback period. It’s also essential to consider available incentives and rebates that could reduce the upfront costs and shorten the payback period.
